Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance will have a low potential for adsorption to organic matter of soils and sediments and for bioaccumulation in aquatic organisms at environmental relevant pH values.
Key value for chemical safety assessment
Additional information
Hexanoic acid, 3,5,5-trimethyl-, tin (2+)salt (2:1) undergoes
dissociation in contact with water :
a. Sn (II) will be oxidized to insoluble Sn (IV)O2: for this inorganic
species, the determination of log Kow is not required (REACH regulation,
Annex VII, column 2)
b. 3,5,5-trimethylhexanoic acid: Based
on the log Kow = 2.83 at pH 2.8 and the corresponding logKow (log D) =
0.65 at pH 7 of the organic dissociation product of the ionic substance,
the substance will have a low potential for bioaccumulation in aquatic
organisms and a low potential for adsorption to organic matter of soils
and sediments at environmental relevant pH values.
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.
