Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts
- Type of composition:
- boundary composition of the substance
- State / form:
- solid: bulk
- Reference substance:
- Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts
- Reference substance:
- Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts
- Reference substance:
- Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts
- Reference substance:
- Sulfuric acid, mono-C12-14 (even numbered)-alkyl esters, ammonium salts
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment for CAS 90583-11-2 is based on the criteria set out in the "Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment" (ECHA, 2008).
Persistence (P) Assessment:
A substance is not considered to be persistent if it can be demonstrated that it has potential to degrade (via photolysis, hydrolysis and/or biodegradation). Several studies using standardized test guidelines could demonstrate the ready biodegradability of the substance (79.1% after 28 days based on CO2 evolution, OECD 301 B). Therefore, CAS 90583-11-2 does not meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation (B) Assessment:
The value of log Pow at 20 ºC is in the range between 0.8 and 0.91. Available data indicate that CAS 90583-11-2 has a very low potential for bioconcentration and the substance will not accumulate to significant levels in the aquatic environment. Therefore, CAS 90583-11-2 does not meet the Bioaccumulative (B) or very Bioaccumulative (vB) criteria.
Toxicity (T) Assessment:
Environmental Toxicity:
According to Annex XIII of REACH Regulation (EC) No 1907/2006, a substance is considered to be toxic in terms of PBT criteria if long-term NOEC values for aquatic organisms are lower than 0.01 mg/L. The NOEC value based on chronic data on daphnids was 0.508 mg/L. This value exceeds the toxicity criterion and therefore, CAS 90583-11-2 is not considered as a toxic substance regarding ecotoxicological endpoints.
Human Health Toxicity:
Carcinogenicity: the available data on CAS 90583-11-2 do not warrant classification for carcinogenicity under GHS/CLP.
Mutagenicity: the available data indicate that CAS 90583-11-2 is not genotoxic or mutagenic and do not warrant classification for carcinogenicity under GHS/CLP.
Reproductive Toxicity: there is no evidence that CAS 90583-11-2 causes reproductive or developmental toxicity. The available data indicate that members of the alkyl sulfate category are not toxic to reproduction and do not warrant classification under GHS/CLP.
Chronic toxicity: due to the results of the relevant mammalian toxicity studies CAS 90583-11-2 is not classified as STOT RE.
The substance is considered not to be PBT or vPvB on the basis of the provided relevant data.
Reference
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
