Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Alcohol Ethoxylates (AE) category are readily biodegradable. All available screening studies, investigating the ready biodegradability of the substances, demonstrated degradation rates > 60% after 28 days. The substances of the Alcohol Ethoxylates (AE) category are expected to be ultimately degraded in the environment and persistence of the substances is unlikely. Based on the available results 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.



The substances of the Alcohol Ethoxylates (AE) categoryhave a limited potential to bioaccumulate. Overall, the potential to bioaccumulate increases with the alkyl chain length of the substances. This correlation is also reflected by the higher log Pow of long-chain AE substances. Literature data on the bioaccumulation potential of alcohol ethoxylates indicate a rapid biotransformation and elimination of the substances (Tolls, 1998; Tolls et al., 2000). A positive correlation between elimination rate alkyl chain length has been demonstrated for alcohol ethoxylates. Due to a rapid metabolisation of the substancesa long-term retention of AE in tissue is not expected.

Alcohol Ethoxylates (AE) category are not considered to be B or 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 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.



The substance is not PBT/vPvB.
