Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment of C8-14AS TEA (CAS 85665-45-8) 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). A study using standardized test guideline is available for C8-14AS TEA (CAS 85665-45-8) that could demonstrate the ready biodegradability of the substance (92% biodegradation after 30 days based on O2 consumption, OECD 301 D). Therefore, C8-14AS TEA (CAS 85665-45-8) does not meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation (B) Assessment:
The log Pow value was determined to be ≤ -0.76. The available data indicates that C8-14AS TEA (CAS 85665-45-8) has a very low potential for bioconcentration and the substance will not accumulate to significant levels in the aquatic environment. Therefore, C8-14AS TEA (CAS 85665-45-8) 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 experimental data on daphnids was 0.172 mg/L. This value exceeds the toxicity criterion and therefore, C8-14AS TEA (CAS 85665-45-8) is not considered as a toxic substance regarding ecotoxicological endpoints.
Human Health Toxicity:
Carcinogenicity: the available data on C8-14AS TEA (CAS 85665-45-8) do not warrant classification for carcinogenicity under Directive 67/548/EEC or GHS/CLP.
Mutagenicity: the available data indicate that C8-14AS TEA (CAS 85665-45-8) is not genotoxic or mutagenic and do not warrant classification for carcinogenicity under Directive 67/548/EEC or GHS/CLP.
Reproductive Toxicity: There is no evidence that C8-14AS TEA (CAS 85665-45-8) 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 Directive 67/548/EEC or GHS/CLP.
Chronic toxicity: due to the results of the relevant mammalian toxicity studies, C8-14AS TEA (CAS 85665-45-8) is not classified as Xn, R48 or STOT RE.
The substance is considered not to be PBT or vPvB on the basis of the provided relevant data.
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).
