Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 adsorption coefficient (Koc) of the substance on soil and on sewage sludge was estimated in a study conducted in compliance with GLP according to OECD TG 121 (HPLC method). Solutions of reference substances with known log Koc values based on soil adsorption data and the substance were analysed by HPLC using a Hypersil BDS-CN column at 35 °C. The log k’ values of reference substances were plotted against the known log Koc values. The log Koc value for the test substance was calculated by substituting its mean log k’ in the calibration curve. The Koc and log Koc values of the main component of the substance at neutral pH were 620 L/kg and 2.79 respectively and cover all constituents of Terpinyl Acetate multi.
Key value for chemical safety assessment
- Koc at 20 °C:
- 620
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.
