Additional information
Conclusion on classification
Tallow bis(hydroxyethyl)amine oxide is readily biodegradable and has a relatively low measured log Kow (ratio of octanol solubility and CMC) of 2.95 indicating a low lipophilicity and related low potential for bioaccumulation.
Tallow bis(hydroxyethyl)amine oxide is similar to the primary alkyl amines, diamine and primary alkylamine ethoxylates (2EO) expected to be rapidly metabolized in fish. BCFBAF estimates a half-life in fish of 0.17 days (normalized to 10 g fish)
There are acute aquatic ecotoxicity test result available for fish, daphnia and algae with a lowest ErC50 of 0.111 mg/L.
Based on the available ecotoxicity data, tallow bis(hydroxyetyl)amine oxide should be classified as
Acute 1, M-factor: 1 (0.1<EC50≤1)
Chronic classification is based on the acute data not possible because tallow bis(hydroxyethyl)amine oxide is readily biodegradable and has a low bioaccumulation potential.The available long term daphnia EC10 of 0.0178 mg/L is therefore used for the chronic classification and derivation of the long term M-factor because of the ready biodegradability and low bioaccumulation potential of the test substance.
Chronic 2, M-factor: - (0.01< EC10≤0.1)
