Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT status:
the substance is not PBT / vPvB

The PBT Assessment is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).



The substances of the alkyl ether sulfates (AES) category are readily biodegradable. All available screening studies demonstrated degradation rates >= 69 - 100% after 28 days. Alkyl ether sulfates are expected to undergo ultimate degradation. Persistence in the environment is unlikely.

Based on the available experimental data, the substances of the Alcohol Ethoxylates (AE) category do not meet the screening criterion for persistence and is not considered to be P or vP.



Alkyl ether sulfates have a limited potential to bioaccumulate. The substances are expected to be rapidly biotransformed and eliminated.

The substances of the alkyl ether sulfates (AES) category are not considered to be B or vB.



The available experimental data show no acute or chronic effect concentrations below the trigger value of 0.01 mg/L (EC50/10 or NOEC). Moreover, the substances of the alkyl ether sulfates (AES) category are not classified according to the consolidated version of Regulation (EC) No 1272/2008 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.

The assessment is based on the data currently available. New studies, based on the category review and the final decisions issued for some category substances are ongoing. The T assessment will be re-evaluated and adapted, if necessary, as soon as all data is available.

Likely routes of exposure:

The substance is neither a PBT nor a vPvB substance; therefore, an emission characterisation is not required.
