Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
All results from aquatic tests show that the test item has no toxic effect up to the measured water solubility. For the quantitative calculations using EUSES 2.1.1 EC50 values of 53.3 mg/L (CMC) was used. Although this conservative approach is used for the calculation of RCR’s a safe use can be shown. All RCR’s are below 1. The real EC50 values and therefore the real PNEC values will be clearly above 53.3 mg/L.
Conclusion on classification
No toxic effect up to the water solubility 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, dodecyl ester potassium salt has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.
