Conclusion on classification

Sodium oleylamphopolycarboxy glycinate has a high water solubility of 630 g/L and a low measured octanol water partition coefficient indicating a low lipophilicity and related low potential for bioaccumulation.

Sodium oleylamphopolycarboxy glycinate is considered to be readily biodegradable based on read across from the analogue substance Sodium tallowamphopolycarboxy glycinate.

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 oleylamphopolycarboxy glycinate should be classified as

Acute 1, M-factor: 1 (0.1<EC50 ≤1)

Chronic classification is based on the acute data because Sodium oleylamphopolycarboxy glycinate is inherently biodegradable. The available algae ErC50 of 0.53 mg/L is therefore used for the chronic classification and derivation of the long term M-factor because of the inherent biodegradability.

Chronic 1 (0.1 < EC50 ≤ 1)

M-factor: 1 (NRD and 0.1< EC10 ≤ 1)
