Description of key information
Additional information
Based on the results of a short-term toxicity study to fish according to OECD guideline 203, the test item Reaction product of oleyl alcohol with polyphosphoric acid had no toxic effect at aquatic saturation (i.e. 100% v/v saturated solution, equivalent to 100 mg/L nominal concentration) on Zebrafish. The 96 h-NOEC value was determined as the saturation concentration and the LOEC and the EC50 values were determined to be higher than saturation.
In a 48-hour acute toxicity test with Daphnia magna according to OECD guideline 202 with the test item the 48 h EC50 and EC100 as well the LOEC values were determined to be higher than 100 mg/L, and the 48 h NOEC was determined as 100 mg/L. The results are based on the nominal test item concentrations.
In a 72-h algal growth inhibition test with Pseudokirchneriella subcapitata according to OECD guideline 201, the obtained results showed that the test item Reaction product of oleyl alcohol with polyphosphoric acid had no toxic effect at aquatic saturation (i.e. 100% v/v saturated solution, equivalent to 100 mg/L nominal concentration) on the algae. Accordingly, the EC10, EC50 and the LOEC values based on growth rate and yield were determined to be higher than the solubility level of the test item in the test medium which corresponds to a nominal value of > 100 mg/L.
Under the conditions of an Activated Sludge Respiration Inhibition Test according to OECD guideline 209, the EC50 value of test item was determined as higher than 100 mg/L. Based on the statistical evaluation in this test the NOEC was 19 mg/L.
The reaction product of oleyl alcohol with polyphosphoric acid is insoluble (see IUCLID section 4.8 Water solubility) and revealed no acute environmental hazard to fish, aquatic invertebrates or algae, thus, the long-term testing to fish and aquatic invertebrates was waived in accordance with column 2 REACH Regulation (EC) No 1907/2006 Annex IX section 9.1.
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).
