Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Bioaccumulation in organisms is negligible, due to biotransformation and excretion of propoxylated alcohols.

Key value for chemical safety assessment

Additional information

In the publication on the bioconcentration of the analogue alkylethoxylates (Tolls et al., 2000) the reported BCF-values ranging from <5 to 387.5 whereas uptake rates varied from 330 to 1660 (L x kg/d) and elimination rates varied from 3.3 to 59 per day. The authors stated that the time of steady state and the BCF increase with increasing chain length of alkyl chain. The substance with alkyl-chain length comparable to the given propoxylated alcohol is C16EO8. For this substance Tolls et al. (2000) reported a BCF-value of 387.5 L/kg.
