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.

Description of key information

Acute tests on all three trophic levels were performed to examine the aquatic toxicity of ´α,α'-propylenedinitrilodi-o-cresol´.

Algae were the most sensitive species revealing an EC50 (72h) of 1.117 mg/L. Thus, the ´α,α'-propylenedinitrilodi-o-cresol´ is considered to be acutely toxic to aquatic organisms. Studies on the effects of the test item towards fish and daphnia support this conclusion by providing a LC50 (96h) of approximately 46 mg/L for fish and an EC50 (48h) of 3.162 mg/L for Daphnia.

The ErC10 value from the study with algae was 0.116 mg/L (measured). No data on long-term toxicity on fish and aquatic invertebrates are available.

The chemical safety assessment of the registered substance does not indicate the need to further investigate long-term effects on aquatic organisms.
