Additional information

Classification is not triggered based on available data, according to REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006.

Conclusion on classification

Classification of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate for effects in the environment

In determining the classification appropriate tosodium 2-(2-dodecyloxyethoxy) ethyl sulphate, it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behavior that may present a long-term and/or delayed danger to the structure and/or functioning of aquatic ecosystems. These points are considered below. 

 

Persistence 

Reliable studies are available to demonstrate thatsodium 2-(2-dodecyloxyethoxy) ethyl sulphateis non persistent in nature and so is considered to have rapid biodegradation in the environment. In other words, sodium 2-(2-dodecyloxyethoxy) ethyl sulphate degradation may therefore be expected to be fast. Thus it can be inferred thatsodium 2-(2-dodecyloxyethoxy) ethyl sulphate is non persistent in character.  

  

Thus, sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is not classified as a persistent (P) chemical. 

 

Potential to accumulate

The estimated log Kow values forsodium 2-(2-dodecyloxyethoxy) ethyl sulphateis less than 4 (Log Kow = -0.602). The potential forsodium 2-(2-dodecyloxyethoxy) ethyl sulphateto bioaccumulate in the tissues of organisms that inhabit aquatic or terrestrial matrices is negligible as the BCF factor for the substance is less than 2000.   

 

The estimated BCF ofsodium 2-(2-dodecyloxyethoxy) ethyl sulphateis highest 71 dimensionless and below the threshold of 2000. 

 

Thus, sodium 2-(2-dodecyloxyethoxy) ethyl sulphate does not satisfy the criterion for classification as bioaccumulative (B).

 

The toxicity values of fish, invertebrates and algae are LC50 = 102.59 mg/L, LC50 = 86.09 mg/L and EC50 = 115.075 mg/L, respectively. But the BCF value of sodium 2-(2-dodecyloxyethoxy) ethyl sulphate reported was not >= 500 as well as the substance was found to be rapidly degradable. (Does not fullfill CLP criteria for toxic classification).

 

So, sodium 2-(2-dodecyloxyethoxy) ethyl sulphate does not satisfy the environmental effects criterion for classification as toxic (T).

 

Thus it can be inferred that sodium 2-(2-dodecyloxyethoxy) ethyl sulphate is not a PBT (including vPvB) substance
