Additional information

Phototransformation in air :

The atmospheric oxidation half-life of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of sodium 2-(2-dodecyloxyethoxy)ethyl sulphate in air is only 0.35 days. This indicates that sodium 2-(2-dodecyloxyethoxy)ethyl sulphate is rapidly phototransformed in air.

OVERALL OH Rate Constant =0.000000000045cm3/molecule-sec at 25 degC.

Hydrolysis :

The Hydrolysis rate constant of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is estimated to be 0.0000000000454767 cm3/molecule-sec. at half life of 2.822 hrs.The estimated half life of the substance indicates that the substance is moderately hydrolysable.

Phototransformation in water

No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.

Phototransformation in soil

No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.
