Conclusion on classification

Sodium cocopropylenediamine propionate has a high water solubility of 356 g/L and a low octanol water partition coefficient of -2.74 indicating a low lipofilicity and related low potential for bioaccumulation.

Sodium cocopropylenediamine propionate was found to be readily biodegradable.

There are acute aquatic ecotoxicity test result available for fish, daphnia and algae with a lowest EC/LC50 of 1.6 mg/L

Based on the available ecotoxicity data, Sodium cocopropylenediamine propionate should be classified as Chronic 4
