Conclusion on classification
No toxic effect was shown in all aquatic tests.
This means that according to the criteria used by the Dangerous Substance Directive (DSD) 67/648/EEC and the 2nd ATP of Classification Labelling and Packaging Regulation (CLP) 2011/286/EC phosphoric acid, butyl ester has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.
