Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis and photodegradation are not relevant for the substance Fatty acids, C8-10, zinc salts.
Additional information
According to Annex VIII Column 2 of Regulation (EC) 1907/2006), information on hydrolysis is not required for biodegradable substances.
Regarding phototransformation/photolysis, Fatty acids, C8 -10, zinc salts is produced from natural fatty materials, i.e. fatty acids (octanoic acid (C8) and decanoic acid (C10)), and consists of approximately 84 % natural fatty acids and a maximum of 19.0 % zinc. The zinc moiety is an inorganic element and thus neither a subject to hydrolysis nor to photodegeneration. AOPWin (v.1.92) calculations result in photodegradation half-lifes of 15,372 and 11,485 hours for octanoic and decanoic acid, respectively. However, photodegradation is not expected to be relevant for Fatty acids, C8 -10, zinc salts under typical environmental conditions due to dominant biotic degradation processes.
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.
