Additional information

Al valid EC50/LC50 values are above 100 mg/L. Therefore no hazard identified. As a worst case scenario for risk assessment the EC50 is set to 100 mg/L.

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 Reaction mass of methyl dihydrogen phosphate and orthophosphoric acid and dimethyl phosphate has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.
