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 Cocoyl glutamate for effects in the environment

In determining the classification appropriate to Sodium Cocoyl glutamate, it is necessary to consider all available evidence concerning its persistence, potential to accumulate and predicted or observed environmental fate and behaviour 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

 

Available data indicates that Sodium Cocoyl glutamate is not persistent in the aquatic and soil environment. Its persistent characteristics are only observed in the sediment compartment and hence it has been concluded that Sodium Cocoyl glutamate can be classified as a non- persistent chemical in nature.  

 

Thus, Sodium Cocoyl glutamate is classified as a non-persistent (P) chemical. 

 

Potential to accumulate

The estimated log Kow values for Sodium Cocoyl glutamate is less than 4 (Log Kow = 0.224). The potential for Sodium Cocoyl glutamate to 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 of Sodium Cocoyl glutamate is 10 dimensionless and below the threshold of 2000. 

 

Thus, Sodium Cocoyl glutamate does not satisfy the criterion for classification as bioaccumulative (B).

 

The toxicity values of fish, invertebrates and algae are LC50 = 135.98 mg/L, EC50 = 165.3484 mg/L and EC50 = 122.6892 mg/L, respectively. These values suggest that the classification for aquatic toxicity will not be applicable for all of the three tropic levels. 

 

So, Sodium Cocoyl glutamate does not satisfy the environmental effects criterion for classification as toxic (T).

 

Thus it can be inferred that Sodium Cocoyl glutamate is not a PBT (including vPvB) substance.
