Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

ELR50>1000mg/l and NOAEC>1000mg/l (based on a loading rate of 1000mg/l)  Measured TOC of this water accomodated fraction was 1.15mg/l (as TOC)

Key value for chemical safety assessment

Fresh water invertebrates

Effect concentration:
1 000 mg/L

Additional information

In an acute GLP guideline toxicity study using a C10/C12 polyalphaolefin, daphnia magna were exposed to a water accommodated fraction (WAF) at a loading rate of 1000mg/l for 48 hours under static test conditions. The measured total organic content of this solution was1.15mg/l. No immobilisation or adverse reactions to exposure were recorded during this period and hence the 48 hour effective loading rate (ELR50) and NOEC were both greater than or equal to 1000mg/l. This conclusion is supported by QSAR modelling.
