Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
All aquatic tests were performed using the test substance diluted in an 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. This is also the reason for the high effect value determined in the acute toxicity test to fish (LC50(96 h)= 562 mg/L) although the water solubility of the test item is <0.1 mg/L. 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.
Conclusion
Based on the available results, the registered substance does not exhibit acute toxicity effects at its solubility limit to the three trophic levels and the microorganisms.
Conclusion on classification
The registered substance is slightly soluble in water and does not exhibit acute toxicity effects to the three trophic levels at its solubility limit (<0.1 mg/L). Further the substance is not readily biodegradable but does not have a potential for bioaccumulation.
As a conclusion to the results listed above the substance does not have to be classified.
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).
