Brief Profile

Data platform availability banner - brief profile

Please be aware that the REACH registration parts of this Brief Profile are no longer maintained; they remain frozen as of 19th May 2023. All other data parts (substance identity, C&L, key regulatory lists etc. are up to date).

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Diss Brief Profile

The Brief Profile summarizes the non-confidential data on substances as it is held in the databases of the European Chemicals Agency (ECHA), including data provided by third parties. The Brief Profile is automatically generated; note that it does not currently distinguish between harmonised classification and minimum classification; information requirements under different legislative frameworks may therefore not be fully up to date or complete. For accuracy reasons, substance manufacturers and imports have the responsibility to consult official sources, e.g. the electronic edition of the Official Journal of the European Union.
This Brief Profile is covered by the ECHA Legal Notice.

Sub. description Substance description Substance description
The ’Substance description’ gives an overview of the main substance identifiers, substance classification, on-going regulatory activities, main uses of the substance and which registrants manufacture and/or import the substance. By summarising this information in a single page, ECHA aims to make this information accessible in a user-friendly way in line with the Agency’s goals and standards.
Data from all dossiers registered and the Classifications and Labelling Inventory (C&L) for the same substance are used to generate the Brief Profile. The information provided in the free-text fields is not published in the Brief Profiles.
The Brief Profile is automatically generated; information requirements under different legislative frameworks may, therefore, not be up-to-date or complete. For accuracy reasons, substance manufacturers and importers are responsible for consulting official sources. This Brief Profile is covered by the ECHA Legal Disclaimer.
Generating the Brief Profiles
The Brief Profile summarises the non-confidential data on substances as it is held in the databases of the European Chemical Agency (ECHA), including data provided by third parties. The Brief Profile is produced based on data in ECHA’s databases and maintained by the Agency, and therefore the Brief Profile as a dissemination tool falls under ECHA’s responsibility.
Due to the quantity of information and the number of chemicals, the Brief Profile is automatically generated based on the information available and is not manually verified. For sections such as substance use, chemical properties and the classification and labelling of substances, the quantity and quality of the information is the responsibility of manufacturers and importers. While the Agency tries to aggregate the information on chemicals in the best possible way, ECHA cannot check whether all the information provided by industry is free of errors.
Updates
Brief Profiles are updated regularly and new information is added when available. Since the source data can be updated at any time while the Brief Profiles are updated at intervals, a slight delay in the publication of information may occur.
The date of the last update corresponds to the publication date of the Brief Profile and not necessarily to the date in which the update occurred in the source data (registered dossiers, the C&L Inventory or a regulatory process).
Furthermore, updates in the source data may not always result in an update of the Brief Profile. For example, an update in a section of a dossier that is not displayed in the Brief Profile will not result in an update of the Brief Profile.

Sci. properties Scientific properties
Scientific properties
The ‘Scientific properties’ section gives an overview of summarised scientific data from registered dossiers. By summarising the endpoint study data, ECHA aims to make this information accessible in a user-friendly way in line with the Agency’s goals and standards.
All the source data on which the summaries on this page are based, is provided by industry and stored in the ECHA databases. Data from all dossiers registered for the same substance is used in the summarisation and aggregation process, as it is presumed that all data submitted by the registrants is relevant for the substance being registered. If the test material used is different from the substance being registered an indication will be provided. Please note that the information provided in the free-text fields is not published in the brief profiles.
Information in the ‘Scientific properties’ section is structured by substance properties, further broken down into endpoints. Each endpoint includes three information blocks:
- Study results – this information is collected from those endpoint study records provided by registrants of REACH dossiers which are flagged as Key or Weight of Evidence studies, and which have an indicated reliability (i.e. Klimisch score) of 1 or 2. Other types of studies are not processed for the Brief Profiles.
- Type of study provided – Provides an overview of the type of study records behind the presented results and data–waving justifications (e.g. key experimental study, Supporting QSAR study, etc.)
- Summary data – this information is collected from the endpoint summaries provided by registrants of REACH dossiers.
Note: Information presented in this section is generated as part of an automatic process, i.e. there is no manual verification or assessment of the correctness of the data. If no data is available in the registered substance dossiers, this will be indicated by a notification stating ‘Data not provided by the registrant’.
Summarisation and prioritisation of data
There are four methods to aggregate and summarise data, depending on the available data and endpoint. An icon is displayed to indicate the type of aggregation and summarisation performed:
- [R] Range of values – Range of results values (min-max) and range values of experimental condition(s) (min-max).
- [C] Concatenate distinct – Value types are ranked from most to least commonly provided, with a % attributed based on the count of total values provided.
- [M/C] Most conservative - Most conservative of all the data values provided, applying a precautionary principle (e.g. the lowest threshold or most hazardous statement)
- [P] Prioritisation – The result to be displayed is based on a set of criteria. For example, for endpoints related to (eco)toxicology four main types of criteria exist to prioritise the display of information: test species, dose descriptor, duration and measurement units. For Toxicology endpoint summaries two other criteria can be applied: Test type (Chronic, subchronic and subacute) and endpoint conclusion.
The precise data summarisation methods are specified per endpoint summary/study.
When more than one numerical result is available per endpoint the count is displayed between square brackets.
Units and data are normalised when possible and therefore the unit of measure/order of magnitude in the Brief Profile data may not correspond exactly to the one in the registered dossier. For temperature for example, data is standardised and displayed in Celsius (°C). For other data an order of magnitude logic might apply; e.g. 1 000 g will be displayed as 1 kg.
Processed studies and data-waiving
Due to the number of the substances and the associated information, substance data is processed and aggregated in an automatic process. Therefore, data has to fit the format and aggregation logic that is used for the Brief Profile.
Though the Agency aims to include as many studies as possible in the Brief Profile endpoint study results/summaries, those studies which do not fit the format or miss crucial information (such as measurement conditions) cannot be processed and therefore will not be included on this page. These study results can however be consulted when opening the source data.
The number of studies provided is indicated by ‘[x] studies submitted’, while the actual number of studies processed for the endpoint is indicated by ‘[x] studies processed’.
Data waiving
If only waived data is available for the substance, following justifications for data-waiving can be displayed in the Brief Profile:
- Study technically not feasible
- Study scientifically unjustified
- Exposure considerations
- Other justification
Excluded endpoints
Some endpoints are not included in the Brief Profile due to the use of free text and/or complex field(s) in the reporting of information, which cannot be easily summarised by an automatic algorithm. Please see the registered dossiers for substance information for the following endpoints:
- Particle size distribution
- Stability in organic solvents and identity of relevant degradation products
- Storage stability and reactivity towards container material
- Stability: thermal, sunlight, metals
- Additional physical-chemical information
- Mode of degradation in actual use
- Other distribution data
- Environmental data (monitoring data/field studies)

Substance Description

Substance identity

Help

The ’Substance identity’ section links substance identification information from all databases that are maintained by ECHA. The substance identifiers – if available and not claimed confidential – displayed in the ’Substance identity’ section of the Brief Profile are:

EC name/number
IUPAC name/number
CAS number
Index number
Molecular formula
Smiles
InChI

In addition, information on the type of substance, origin, number and type of registered compositions and other places where the substance is listed are displayed in this section.

EC (European Community) name/number

The EC name and number are the official identifiers for substances within the European Union and can be found in the EC Inventory.

The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). More information about the EC Inventory can be found here. If the substance has no EC number attributed, ECHA will attribute a list number. These numbers start with 6, 7, 8 or 9.

IUPAC name/number

An IUPAC name is based on the international standard chemical nomenclature set by the International Union of Pure and Applied Chemistry (IUPAC).

The IUPAC nomenclature is a systematic way of naming chemical substances, both organic and inorganic. In IUPAC nomenclature, prefixes, suffixes and infixes are used to describe the type and position of functional groups in the substance.

If more than one IUPAC name is available from REACH registered dossiers, all IUPAC names are displayed in ‘Other names’ section of the Brief Profile.

See the official IUPAC website for more information on the International Union of Pure and Applied Chemistry.

CAS (Chemical Abstract Service) registry number

The CAS number is the substance numerical identifier assigned by the Chemical Abstract Service, a division of the American Chemical Society, to substances registered in the CAS registry database. A substance may have more than one CAS number associated. In this case, the preferred CAS number is displayed first. More about CAS and the CAS registry can be found here.

Index number

The Index number is the identification code given to substances in Part 3 of Annex VI to the CLP Regulation ((EC) No 1272/2008). A distinct classification and labelling corresponds to each Index number.

The Index number for each substance is in the form of a digit sequence of the type ABC-RST-VW-Y. ABC corresponds to the atomic number of the most characteristic element or the most characteristic organic group in the molecule. RST is the consecutive number of the substance in the series ABC. VW denotes the form in which the substance is produced or placed on the market. Y is the check-digit calculated in accordance with the 10-digit ISBN method.

Molecular formula

The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. If such information is available in ECHA’s database and is it not claimed confidential, the molecular formula and molecular structure will be displayed here.

SMILES

SMILES is the acronym for Simplified Molecular Input Line Entry Specification, a chemical notation system used to represent a molecular structure by a linear string of symbols.

With standard SMILES, the name of a molecule is synonymous with its structure: it indirectly shows a two dimensional picture of the molecular structure. Since a two dimensional chemical structure can be drawn in various ways, there are several correct SMILES notations for one molecule.

The basis of SMILES is the representation of a valence model of a molecule. SMILES notations are comprised of atoms (designated by elemental symbols), bonds, parentheses (used to show branching), and numbers (used for cyclic structures).

InChI

InChI is an abbreviated name for IUPAC International Chemical Identifier, a chemical identifier developed and supported by the InChI Trust.

InChIs consist of text strings comprising different layers and sublayers of information separated by slashes (/). Each InChI string starts with the InChI version number followed by the main layer. This main layer contains sublayers for the chemical formula, atom connections and hydrogen atoms. Depending on the structure of the molecule the main layer may be followed by additional layers e.g. for charge, stereo–chemical and/or isotopic information.

Molecular structure

Molecular structure displayed in this section is based on InChI annotation from IUCLID reference substances database and stored in the ECHA database. The structure is a computer generated visualisation of the molecular structure derived from the InChI character string.

Type of substance

Registrants can identify their substance as being a mono-constituent substance, multi-constituent substance, UVCB, polymer or specify another type. If more than one type of substance is registered, both types will be displayed.

Origin

Registrants can identify the origin of their substance as being:

Element
Inorganic
Organic
Organometallic
Petroleum product
Other

If more than one type of substance is registered, both types will be displayed.

Registered compositions (additives and impurities)

The total number of non-confidential registered compositions submitted in REACH dossiers are displayed here. If there are additives and impurities relevant for the substance classification, these are also indicated.

Within the context of REACH, impurities are unintended constituents present in a substance as manufactured. It may, for example, originate from the starting materials or be the result of secondary or incomplete reactions during the production process. While it is present in the final substance, it was not intentionally added. In most cases, impurities constitute less than 10% of the substance.

Additives are the constituents which have been intentionally added during the manufacturing process to stabilise the substance.

Substance listed

Provides information if the substance has been identified by one of the following previous EU chemicals regulatory frameworks:

Hazard classification & labelling

Hazard classification and labelling

The ‘Hazard classification and labelling’ section shows the hazards of a substance through a standardised system of statements and pictograms, as has been established under CLP (Classification Labelling and Packaging) Regulation. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. The CLP Regulation uses the UN Global Harmonised System (GHS) and European Union Specific Hazard Statements (EUH).

This section searches three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). The source of the information is mentioned in the introductory sentence of the hazard statement.

More information about classification and labelling can be found in the Regulations section of ECHA website.

Please note:

The purpose of the information provided under this section is to highlight in a readable format the substance hazardousness. It does not represent a new labelling, classification or hazard statement. Other relevant information includes the following:

Substances may have impurities and additives that lead to different classifications. However, substance notifications in the Brief Profile are aggregated independently of the impurities and additives.
Hazard statements were adapted to improve readability and may not correspond textually to the hazard statements codes description in the European Union Specific Hazard Statements (EUH) or UN Global Harmonised System (GHS).

To see the full list of notified classifications and have more information on impurities and additives relevant to classification, you can consult the C&L Inventory.

Harmonised classification and labelling (CLH)

The Hazard classification and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. Substance classifications under CLH are agreed at the Community level. Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment.

It is possible that the harmonisation is introduced through an amendment to the CLP Regulation. In that case, the ATP (Adaptation to Technical Progress) number is displayed. More information on CLH can be found here.

If the substance is classified under more than one CLH entry (e.g. disodium tetraborate EC no. 215–540–4, is covered by three harmonisations – 005–011–00–4; 005–011–01–1; 005–011–02–9), CLH information cannot be displayed in the Brief Profile as the differences between the CLH classifications require manual verification. If a substance is classified under multiple CLHs, a link to the C&L Inventory is provided to allow users to view CLH information manually, instead of having the information automatically generated in the Brief Profile.

Classification and labelling under REACH

Additional information on classification and labelling (C&L) – if available – is derived from REACH registration dossiers submitted by industry. This information has not been reviewed or verified by ECHA, and may change without prior notice. REACH registration dossiers have greater data requirements (support studies) than notifications under CLP. When submitted by the lead of a joint submission, the classifications may also reveal agreement between companies.

Notifications under the Classification, Labelling and Packaging (CLP) Regulation

If additional information derived from classification and labelling (C&L) notifications to ECHA under the CLP Regulation exists, this will be displayed below the information derived from harmonised classification and labelling and REACH registrations. These notifications can be provided by manufacturers, importers and downstream users. ECHA maintains the C&L Inventory, but does not review or verify the accuracy of the information.

For readability purposes, only the pictograms, signal words and hazard statements referred to in more than 5% of the notifications under CLP are displayed.

According to the notifications provided by companies to ECHA in REACH registrations no hazards have been classified.

Additionally, the classification provided by companies to ECHA in CLP notifications identifies that this substance causes serious eye irritation, is suspected of causing cancer and may cause respiratory irritation.

Breakdown of all 28 C&L notifications submitted to ECHA

Hazard classification & labelling graph

The chart displays the number of matching substance classifications (hazard class, categories and hazard statements) provided by manufacturers and importers under REACH and CLP notifications, as well as whether the substance is defined under harmonised classification and labelling (CLH).

The results of matching substance classifications are displayed in percentages of the total number of notifications. The bars indicate the number of matching classifications, i.e. the level of agreement, in substance classification between the REACH registrants (dark blue bar) and CLP notifiers (light blue bar), as well as between the notified classifications and the approved harmonised classification.

Harmonised classifications (√ - check mark)

The (√- check mark)-icon indicates the classification is defined under harmonised classification and labelling (in accordance with the CLP Regulation) and made obligatory at Community level to ensure an adequate risk management throughout the European Community.

REACH & CLP classifications (bar)

The dark blue bar illustrates the percentage of matching substance classifications provided by manufacturers and importers in a REACH registration dossier. Classifications under REACH have to be supported by data (support studies).
The light blue bar illustrates the percentage of matching substance classifications provided by manufacturers and importers in CLP notifications.

Divergent classifications and impurities

The physical state and form of a substance can play a significant impact when the hazards of a substance are assessed. REACH and/or CLP notifiers may classify a substance differently based on different studies or the way they access the data.

For example, substance impurities can constitute a valid reason for a different classification of the substance. Different compositions or impurity profiles often lead to different classifications. If impurities and/or additives have been identified, an informative sentence is displayed below the graphic.

Different classifications can also be due to technical errors made during the notification process.

To have more information on impurities relevant to classification you can consult the C&L Inventory entry for the substance, or the disseminated registration dossier.

Properties of concern

The ‘Properties of concern’ section shows ECHA-assigned graphical indicators for certain substance properties that are regarded as critical for human health and/or the environment based on the information provided to the Agency. The following properties have been highlighted as critical:

C – This substance was identified as a carcinogenic (i.e. classified in Carcinogenicity categories 1A or 1B) in the EU harmonised classification and labelling and/or in a REACH registration dossier. More information about carcinogenicity here.
M – This substance was identified as Mutagenic (i.e. classified in Mutagenicity categories 1A or 1B) in the EU harmonised classification and labelling and/or by a REACH registration dossier. More information about mutagenicity here.
R – This substance was identified as toxic to reproduction (i.e. classified in reproductive toxicity categories 1A or 1B) in the EU harmonised classification and labelling and/or by a REACH registration dossier. More information about reproductive toxicity here.
Ss – This substance was identified as a skin sensitiser (i.e. classified in skin sensitisation categories 1, 1A or 1B) in the EU harmonised classification and labelling and/or by a REACH registration dossier. More information about skin sensitiser here.
Sr – This substance was identified as a respiratory sensitiser (i.e. classified in respiratory sensitisation categories 1, 1A or 1B) in the EU harmonised classification and labelling and/or by a REACH registration dossier. More information about respiratory sensitiser here.
PBT – This substance was identified as persistent, bioaccumulative and toxic (PBT) by at least one REACH registrant (i.e. it is PBT/vPvB). More information about persistent, bioaccumulative and toxic substances here.
POP – Recognised Persistent Organic Pollutant (POP): comes from an entry in the Annex I, II or III to the POPs Regulation and/or an entry in the Annex A, B or C to the Stockholm Convention. Under assessment as Persistent Organic Pollutant: is shown for substances that have been proposed for their inclusion in the Stockholm Convention and are under assessment, or for which a proposal is under preparation in the European Union. Note that proposals that have been set aside, either before their submission by the EU to the Convention, or by the POP Review Committee are still indicated as "Under assessment as POP".

The substance properties displayed in this section (with the exception of PBT properties) are derived from harmonised classification and labelling (CLH) and/or REACH registered dossier information. In case the substance classification is not harmonised and the substance is not registered the properties are derived from classifications provided in CLP notifications. PBT properties are derived from REACH registered substances dossiers.

Critical property indentification: Where less than 90% of the notifiers provide the same classification to derive the critical property, the border of this critical property icon is displayed as dashed.

Impurities or additives: When a specific critical property is associated with compositions with impurities and/or additives, the respective critical property icon has a * associated.

Please note: The icons in this section are only meant as visual indicators to help communicate information about the abovementioned critical properties. Unlike the pictograms in the ‘Classification and Labelling’ section, these icons are not determined by any legislative procedure and have the sole purpose of being informative in the context of InfoCards and Brief Profiles.

About this substance

The ’About this substance’ section provides an overview of the volume in which this substance is manufactured or imported to the European Economic Area (EU28 + Iceland, Liechtenstein and Norway). Data for calculating the ’total tonnage’ band is extracted from REACH registered dossiers for the last year reported on the tonnage manufactured or imported, unless the tonnage band has been claimed confidential. The ‘total tonnage’ band published does not necessarily reflect the registered tonnage band(s).

For more information on total tonnage band calculation please consult the Data submission manual.

Additionally, if available, information on the use of the substance and how consumers and workers are likely to be exposed to it can also be displayed here. The information is aggregated from REACH registered dossiers provided by industry through a use descriptor system based on five separate descriptor lists which in combination with each other form a brief description of use and exposure for certain life cycle stage.

The use information is displayed per relevant life cycle stage of the substance.

Manufacture stage includes processes by which the substance is manufactured from raw materials. Operations which are necessary for the handling of a substance on its own in the manufacturing for export or placing on the EU market are considered to be part of the manufacturing stage (e.g. filling into appropriate containers, storage or addition of stabiliser). If a substance is directly exported after manufacture, all activities with the substance will be reported under this stage.
Formulation or re-packing stage corresponds to specific activities meant to produce a mixture to be placed on the market. This means that during formulation, the substance is transferred and mixed with other substances. It corresponds to activities taking place at industrial sites. This stage also includes chemical distributorsâ activities such as repacking (which involves transfer of the substance).
End-use stage means the use of a substance as such or in a mixture (by professional workers (widespread uses), by consumers or at industrial sites), a last step before the end-of-life of the substance, namely before the substance is consumed in a process by reaction during use (including intermediate use), is emitted to waste streams or the environment or is included into an article.
(Article) service life stage means the period of time a substance incorporated into an article remains in service or in use. Articles containing the substance can be used or processed by consumers, by workers at industrial sites and/or by professional workers. This also includes processing of semi-finished articles by workers with the aim of producing finished articles or repair and maintenance work like for example sanding of surfaces.

Use Descriptors

The chemical product category (PC) describes the types of chemical products in which the substance is finally contained when it is supplied to end-users (by industrial, professional or consumer users). Examples include hydraulic fluids, perfumes and air care products. This category also describes uses as intermediate and under controlled conditions.
The sector of use category (SU) describes in which sector of the economy the substance is used. This includes mixing or re-packing substances at the formulator’s level as well as industrial, professional and consumer end-uses (e.g. building and construction work or manufacture of food products).
The process category (PROC) describes the application techniques or process types defined from the occupational perspective e.g. Industrial spraying, use in closed batch process (synthesis and formulation).
The environmental release category (ERC) describes the broad conditions of use from the perspective of release to the environment (e.g. if the use occurs in industrial setting, if it is indoor use in long-life materials with a low release rate (e.g. flooring, furniture, toys, etc).
The article category (AC) describes the type of article into which the substance has eventually been processed. This also includes mixtures in their dried or cured form (e.g. dried printing ink in newspapers; dried coatings on various surfaces).

Precautionary measures and safe use

This section provides information on the recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product, or improper storage or handling of a hazardous product. The recommendations are based on the precautionary statements provided in REACH registration dossiers.

If information on guidance on safe use is available in REACH registered dossiers, a link is displayed. Information in the guidance on safe use section consists of recommendations by a substance registrant(s) on the proper use of the substance in various situations. Examples include recommended measures on fire-fighting, transport, recycling and disposal.

More information on the use descriptor system can be found in ECHA’s Guidance Chapter R.12: Use Descriptor system of ECHA’s Guidance on information requirements and chemical safety assessment.

Please note:

Only non-confidential use descriptors are displayed and for readability purpose only use descriptors occurring in more than 5% of the total occurrences are displayed.

Registrants/suppliers

Registrant/suppliers

This section provides information on suppliers, importers or manufacturers of a substance (active and inactive) that have to register their substance under REACH.

Registration status
Status in REACH-IT	Displayed in Brief Profile
Active	Always as Active
Cease manufacture	Always as Inactive
Revoked registrations	Active/Inactive (pending). Due to ongoing appeals, all registrations flagged as revoked are published as Active pending the appeal outcome. When the appeal outcome is known, the registration will appear as Inactive
Annulled registrations	In the case of a merge between two companies having a registration for the same substance, the higher tonnage band registration is maintained as active, and the other registration is annulled. The annulled registration is still legally valid and considered as an active registration, because the registration number could be present on safety fata sheets and may already be communicated throughout the supply chain.

Under specific conditions, a registrant can claim confidentiality of their identity. If there is a confidentiality claim, an indication is provided with the tag [Confidential].

Data not provided by the registrant

Toxicological information

This section provides toxicological information compiled from all automatically processable data from REACH registration dossiers that is available to ECHA at the time of generation. The quality and correctness of the information remains the responsibility of the data submitter. The Agency thus cannot guarantee the correctness of the information displayed.

Derived No- or Minimal Effect Level (DN(M)EL)

This section provides information on the derived no- or minimal effect level (DN(M)EL), the level of exposure above which a human should not be exposed to a substance.

When more than one summary is provided, DN(M)EL values may refer to constituents of the substance and not to the substance as a whole. More detailed information is available in the dossiers.

When more than one result is available per endpoint the ‘worst case’ or most conservative of all the data values provided are displayed, applying a precautionary principal. The aim is to display the lowest values reported as causing the most adverse effects, and hence the broadest possible safety margins for the substance.

Inhalation exposure provides information on the substance’s hazard assessment conclusions regarding inhalation exposure.

Registrant can provide information on the long and acute/short term exposure for both systemic and local effects of inhalation exposure of workers and/or general population by selecting one of the following hazard assessment conclusions:

DNEL (Derived No-Effect Level)
DMEL (Derived Minimum Effect Level) - not included for short–term effects
Other toxicological threshold
High hazard (no threshold derived)
Medium hazard (no threshold derived)
Low hazard (no threshold derived)
Insufficient data available (further information necessary)
Hazard unknown (no further information necessary)
No hazard identified
Hazard unknown but no further hazard information necessary as no exposure expected

Prioritisation of display occurs based on the order above. If a threshold is derived, the type of hazard assessment conclusion is displayed and the registered threshold is reported in (nano/micro/milli)gram per cubic metre. If more than one DNEL/DMEL is available the most conservative (i.e. the lowest numerical data) is displayed.

Information on the most sensitive study can be provided by the registrants as:

Acute toxicity
Repeated dose toxicity
Effect on fertility
Developmental toxicity/teratogenicity
Neurotoxicity
Immunotoxicity
Sensitisation (skin)
Sensitisation (respiratory tract)
Carcinogenicity
Skin irritation/corrosion
Irritation (respiratory tract)
Genetic toxicity

Dermal exposure provides information on the substance’s hazard assessment conclusions regarding dermal exposure (for workers).

See ‘Data for workers – Inhalation exposure’, with the following additional hazard assessment conclusion in the case of short term:

‘No DNEL required: short term exposure controlled by conditions for long-term’ is added

The registered threshold is generally displayed in milligrams per kilogram per bodyweight per day.

Data for workers – eye exposure provides information on the substance’s hazard assessment conclusions regarding eye exposure (for workers).

Registrant can provide information on eye exposure by selecting one of the following hazard assessment conclusions:

High hazard (no threshold derived)
Medium hazard (no threshold derived)
Low hazard (no threshold derived)
Hazard unknown (no further information necessary)
No hazard identified
Hazard unknown but no further hazard information necessary as no exposure expected

Data for general population – eye exposure provides information on the substance’s hazard assessment conclusions regarding eye exposure (for the general population).

Registrant can provide information on eye exposure as mentioned above for ‘Data for workers – eye exposure.’
