Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 for AES (C12-14, 1-2.5 EO) TEA (CAS 157627-94-6) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2014).
Persistence
All members of the category alkyl ether sulfates are readily biodegradable which is proved by many studies available for the certain mixtures. Due to the ready biodegradability of alkyl ether sulfates it is unlikely that the substances persist in the environment. Thus, the test substance does not meet the screening criterion for persistency and is not considered to be persistent (P) or very persistent (vP).
Bioaccumulation
Due to the low log Kow value bioaccumulation is not expected. Thus, the substance does not meet the screening criterion for bioaccumulation and is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
Toxicity
No long-term effects below the trigger value of 0.01 mg/L (EC10 or NOEC) occurred. Moreover, the substance is not classified according to Directive 67/548/EEC and Regulation (EC) No. 1272/2008 (7th ATP) as carcinogen, germ cell mutagenic or toxic for reproduction. Thus, the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 are not met and the test substance is not considered to meet the T criterion.
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.
