Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Endpoint:
flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to REACh Annex XI / section 2, flammability study UN N1 relevant for classification criteria under IUCLID Section 4.13 does not apply to liquids. Please refer to Flash Point under IUCLID section 4.11.
Reason / purpose for cross-reference:
reference to other study
Endpoint:
pyrophoric liquids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
Expert statement : Experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time)
Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to REACh Annex XI / section 1, study for flammability if contact with water is deemed unnecessary, based on the experience in handling, testing and use of the substance.
In particular, in the Surface Tension study, no reaction was reported.
Moreover, the chemical structure that does not fall into critical categories described in the ECHA Guidance on the Application of the CLP Criteria (v5.0, July 2017, §2.12.7.1.) or in the Bretherick’s Handbook of Reactive Chemical Hazards (6th Edition, 1999, Volume 2, water-reactive compounds) (e.g. no acid anhydrides, halides, oxides, alkali metals, alkyl aluminium derivatives, alkyl metals, complex or metal hydrides, metal phosphides, certain metal powders...).
Reason / purpose for cross-reference:
data waiving: supporting information
Endpoint:
self-heating substances / mixtures
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
According to ECHA Guidance on the Application of the CLP Criteria (v5.0, July 2017, §2.11.4.2.), the phenomenon of self-heating generally applies only to solids. The surface of liquids is not large enough for reaction with air and the test method (UN N4) is not applicable to liquids. Therefore liquids, unless adsorbed, are not classified as self-heating.
Moreover, the chemical structure does not contain metals, which are typically self-heating substances.
Reason / purpose for cross-reference:
data waiving: supporting information

Description of key information




Flash Point = 57°C (experimental, EU A9; Currenta, 2010).
No pyrophoric properties, no release of flammable gases if contact with water, no self-heating anticipated. (waived)




Key value for chemical safety assessment

Flammability:
flammable

Additional information

The flammability of a substance under the present endpoint is determined following UN N.1 method. However, in accordance with section 2 of REACH Annex XI, this study is technically not feasible as the substance is a liquid. The relevant test to assess flammable properties of a liquid is the Flash Point measurement. A fully reliable experimental study is presented under IUCLID section 4.11.


Based on experience in production or handling, Benzyldimethylamine has no pyrophoric properties.


Based on the structural formula, Benzyldimethylamine does not emit flammable gases on contact with water.





As a liquid, no self-heating is anticipated either.




Justification for classification or non-classification




According to Regulation (EC) No.1272/2008 (CLP) criteria, the measured flash point is between the threshold values of 23 and 60°C, therefore the substance is considered as a FLAMMABLE LIQUID in category 3.
