Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
- Koc at 20 °C:
- 1 000
Additional information
For the estimation of sorption, Koc is used to estimate partitioning coefficients in various compartments. There are there estimated values of Koc for Chiguard 380/Chiguard 380W using there different empirical methods, the results are as below:
Kenaga and Goring correlation (1980): LogKoc=3.934 or Koc=8590;
Hodson and Williams correlation (1988): LogKoc=4.179 or Koc=15100
Computer calculation using PCKOC by saracuse research Corporation: LogKoc=5.283 or Koc=191870
All the above Koc estimates are above 1000, and indicate that the substance will be tightly bound to organic matter in soil.
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.
