PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

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).



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).


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).



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.
