Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Readily biodegradable: 83% in 28 days (OECD 301B)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

A new OECD 301 B study is available, investigating the ready biodegradability of Reaction mass of sodium hydrogen N-(1-oxooctadecyl)-L-glutamate and stearic acid. After 28d the degradation was determined to be 83% based on CO2-evolution fulfilling the 10d window (64%). Based on the results, sodium hydrogen N-(1-oxooctadecyl)-L-glutamate and stearic acid is consdered to be readily biodegradable.
