Description of key information
The aerobic biodegradation of Reaction mass of Sodium ethylenesulphonate and Isethionate-bisether disodium salt was estimated by the models Biowin 1 and Biowin 2, included in BIOWIN, which are intended to convey a general indication of biodegradability under aerobic conditions, and not for any particular medium. The models show that Reaction mass of Sodium ethylenesulphonate and Isethionate-bisether disodium salt biodegrades fast.
Half lives in surface water and sediment were estimated with the PBT profiler (US-EPA) which calculates half life values from ultimate biodegradation estimations in the Biowin 3 model included in BIOWIN. The calculated half life values for Reaction mass of Sodium ethylenesulphonate and Isethionate-bisether disodium salt are 15 days for surface water and 140 days for sediment.
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- Half-life in freshwater sediment:
- 140 d
Additional information
The aerobic biodegradation of Reaction mass of Sodiumethylenesulphonateand Isethionate-bisether disodium salt was estimated by models Biowin 1 and Biowin 2, included in BIOWIN version 4.10. Biowin 1 (Linear Biodeg Probability) and Biowin 2 (Non-Linear Biodeg Probability), are intended to convey a general indication of biodegradability under aerobic conditions, and not for any particular medium. A biodegradation probability between 0.5 and 1 is considered as "biodegrades fast". The biodegradation probability of Reaction mass of Sodiumethylenesulphonate and Isethionate-bisether disodium salt is 0.8044 in biowin1 and 0.998 in Biowin2, showing that the substance biodegrades fast.
Half lives in surface water and sediment were estimated with the PBT profiler (US-EPA) which calculates half life values from ultimate biodegradation estimations in the Biowin 3 model included in BIOWIN. The calculated half life values for Reaction mass of Sodiumethylenesulphonateand Isethionate-bisether disodium salt are 15 days for surface water and 140 days for sediment. To account for the slower biodegradation under anaerobic conditions in the deeper layers of the sediment, the overall half life in sediment is estimated to be about 9 times higher than the half life in water.
The calculated results have no impact on classification but can be used for risk assessment.
Test results from simulation tests in water or sediment are not available.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
