Additional information
Conclusion on classification
Sodium cocoamphopolycarboxy glycinate has a high water solubility of 575 g/L and a low measured octanol water partition coefficient indicating a low lipophilicity and related low potential for bioaccumulation.
Sodium cocoamphopolycarboxyglycinate was biodegraded by 35% at day 28 in the Closed Bottle test. This test substance should therefore not be classified as readily biodegradable. In the prolonged Closed Bottle test sodium cocoamphopolycarboxyglycinate was biodegraded 39% at day 60. The biodegradation curve levels off between 20 and 60% biodegradation (Figure) suggesting partial degradation of the test substance. Van Ginkel (1996) found however 64% degradation on day 140 for the tallow based amphopolycarboxy glycinate indicating that despite of the slow biodegradation the structures are ultimately biodegradable.
There are acute aquatic ecotoxicity test result available for fish, daphnia and algae with a lowest EC/LC50 of 0.53 mg/L.
Based on the available ecotoxicity data, Sodium cocoamphopolycarboxy glycinate should be classified as
Acute 1, M-factor: 1 (0.1<EC50 ≤1)
Chronic classification is based on the acute data because Sodium cocoamphopolycarboxy glycinate is not readily biodegradable. The available lowest EC50 as observed for algae of 0.53 mg/L is therefore used for the chronic classification and derivation of the long term M-factor.
Chronic 1, M-factor: 1 (0.1<EC50≤1)
