Description of key information
The reaction mass of aminophosphonium salt and bisphenol AF (XA31) has been tested for its toxicity to aquatic organisms. Acute E(L)C50 values were measured in the range >1-10 mg/L (fish, daphnids, algae) while a chronic NOEC value was measured at 1 mg/L (algae).
Aquatic toxicity data have been reported for the two main constituents of the reaction mass, i.e. the aminophosphonium salt and bisphenol AF (cf. REACH disseminated dossiers - not included here). Both constituents exhibit aquatic toxicity data very similar to the ones measured on the reaction, except for the chronic toxicity data on algae. For this endpoint, a 72h-NOEC value of 0.052 mg/L has been reported for bisphenol AF, which is significantly lower than the 72h-NOEC value of 1 mg/L reported for the reaction mass. Considering the analytical deficiencies of the algal toxicity study performed on the reaction mass, it is found preferable to use for the assessment, as a worst-case, the 72h-NOEC value reported for bisphenol AF. This worst-case approach is all-the-more relevant as the aquatic (chronic) toxicity of the reaction mass is not expected to be driven by the aminophosphonium salt.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
