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 40 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

Half-life in freshwater:
38 d
at the temperature of:
25 °C
Half-life in freshwater sediment:
340 d
at the temperature of:
25 °C
