Ready biodegradability tests for several alkyl sulfates are available. Based on the results of screening tests for biodegradation in water it can be concluded that alkyl sulfates with carbon chain length of C8-C18 are readily biodegradable according to OECD criteria (OECD SIDS 2007).

Moreover, a study confirming ready biodegradation of C16-20AS Na (CAS 91648-55-4) performed according to OECD 301 B guideline is available. The substance is readily biodegradable according to OECD criteria: 100% of biodegradation was observed after 28 days based on CO2 evolution.
