Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxicity to microorganisms of the test substance was investigated and
an EC50 of >10000 mg/L was observed. The effect value relates to nominal concentration, since no analytical monitoring was performed.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 10 000 mg/L
Additional information
"should read: >10000 mg/L"
All aquatic tests were performed using the test substance diluted in a 8 : 17 mixture of 1-methoxy-2-propyl acetate (CAS: 108-65-6) and solvent naphtha 100 (CAS: 64742-95-6), respectively. The test solution consisted to 75 % of the test item and to 25 % of the 1-methoxy-2-propyl acetate/solvent naphtha mixture. As the test substance is only marketed in the above described composition, these tests can be used for the evaluation of the environmental risks of the substance. The results further display a worst case as the test substance is almost insoluble in water and will therefore not be available in large amounts (if at all) in aquatic test systems. As a conclusion the aquatic toxicity studies with the test substance diluted in organic solvents can be used as a worst case describing the toxicological behaviour of the test substance against aquatic organisms.
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.
