Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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.
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.
