Description of key information

Sulfuric acids, C9-11-iso-C10 rich, alkyl esters, sodium salt is hydrolytically stable under environmental conditions.

Key value for chemical safety assessment

Additional information

No hydrolysis studies are available for Sulfuric acids, C9-11-iso-C10 rich, alkyl esters, sodium salt. Nevertheless, the test substance is readily biodegradable and therefore hydrolysis testing does not have to be performed.

The OECD SIDS Initial Assessment Report for category of alkyl sulfates, alkane sulfonates and α-olefin sulfonates (2007) states that alkyl sulfates are susceptible to hydrolysis in hot alkaline and acidic media and hydrolyze to sulfate and the corresponding alcohol. However, under environmental conditions alkyl sulfates are considered to be hydrolytically stable.
