Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The half life period of sodium 2-(2-dodecyloxyethoxy)ethyl sulphate in water is 38 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of sodium 2-(2-dodecyloxyethoxy)ethyl sulphate in water medium is 15 %. This coupled with the dilution of water shall result in ready biodegradabililty of the chemical.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Based on studies of target substance sodium 2-(2-dodecyloxyethoxy) ethyl sulphate reviewed for Biodegradation in water: screening tests from reliable sources having Klimisch rating 2.
