Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 performance of an adsorption/desorption study is not required as the test substance hexanoic acid, 3,5,5-trimethyl-, tin (2+)salt (2:1) undergoes dissociation in contact with water: The dissociation products Sn (IV)O2) and 3,5,5-trimethylhexanoic acid are insoluble in water and indicate a low sorption potential, respectively.
Key value for chemical safety assessment
Additional information
According to REACH Regulation (Annex VIII, 9.3.1, column II), the study on sorption/desorption does not need to be done if based on the physico-chemical properties a low sorption potential is to be expected (e.g. low log Kow) or the test substance decays rapidly. Hexanoic acid, 3,5,5-trimethyl-, tin (2+)salt (2:1) undergoes dissociation in contact with water: Sn (II) will be oxidized to insoluble Sn (IV)O2) and the calculated log D of 0.65 at 25°C and pH7 of 3,5,5-trimethylhexanoic acid indicates a low sorption potential. Furthermore, the test substance proved to be readily biodegradable in a guideline study.
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.
