Conclusion on classification

Aquatic environment classification

Based on the available data acetyl tributyl citrate is considered to be rapidly biodegradable, both in aquatic media and soil.

The most sensitive short-term endpoint is the 21d-NOEC from a limit test with Daphnia magna of ≥ 1.11 mg test item/l

, representing a conservative estimate of aquatic toxicity.

Due to rapid degradation and considering the insignificant bioaccumulation potential, the substance is not to be classified as dangerous/hazardous for the environment according to Directive 67/548/EEC or according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP).
