Description of key information

The Coco fatty acids 2-sulfoethyl ester, sodium salt is considered to be readily biodegradable. Coco fatty acids 2-sulfoethyl ester, sodium salt is a UVCB substance and therefore was the 10-day windows not evaluated. No toxicity to the inoculum was observed at 1.62 mg a.i./L

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The ready biodegradability of the test substance was determined in four different tests. Coco fatty acids 2 -sulfoethyl ester, sodium salt was found to be readily biodegradable in all four tests. In the key study by van Ginkel, a Closed Bottle test according to the slightly modified OECD, EEC and ISO test guidelines under GLP conditions is described and here already after 14 days 80% degradation was observed. After 28 day 78% degradation was observed. No toxicity to the inoculum was observed.
