Description of key information
The PBT Profiler & EPI Suite has estimated that sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days,does not exceeds the threshold of 120 days as per Annex XIII of REACH.Therefore, sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is estimated to be not persistent in the soil environment.
Key value for chemical safety assessment
- Half-life in soil:
- 75 d
- at the temperature of:
- 25 °C
Additional information
Based on studies of target substancesodium 2-(2-dodecyloxyethoxy) ethyl sulphate reviewed for Biodegradation in soil from reliable sources having Klimisch rating 2.

By applying weight of evidence approach the target chemical found to be not persistent with half life 68 to 75 days which does not exceeds the threshold (120 days) of not being persistent in soil.Thus it is concluded that sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is biodegradable in soil.
