Additional information
Conclusion on classification
Sodium tallowamphopolycarboxy glycinate has a high water solubility of 640 g/L and a low measured octanol water partition coefficient indicating a low lipophilicity and related low potential for bioaccumulation.
The available biodegradation data indicate that Sodium tallowamphopolycarboxy glycinate is <60% biodegraded on day 28. Prolongation of the tests till day 140 shows that Sodium tallowamphopolycarboxy glycinate is ultimately biodegradable.
There are acute aquatic ecotoxicity test result available for fish, daphnia and algae with a lowest EC/LC50 of 0.39 mg/L
Based on the available ecotoxicity data,Sodium tallowamphopolycarboxy glycinate should be classified as
Acute 1, M-factor: 1 (0.1 < EC50 ≤ 1)
Chronic classification is based on the acute data because Sodium tallowamphopolycarboxy glycinate is not readily biodegradable. The available fish LC50 of 0.39 mg a.i./L is therefore used for the chronic classification and derivation of the long term M-factor.
Chronic 1, M-factor: 1 (0.1 < LC50 ≤ 1)
