According to Annex VIII Column 2 of regulation (EC) 1907/2006), information on hydrolysis is not required for biodegradable substances.

Regarding Phototransformation/photolysis, the substance Fatty acids, C14-18 and C16-18-unsatd., zinc salts is produced from natural fatty materials, which is amixture of stearic (C18), palmitic (C16) and myristic acid (C14). Fatty acids, C14-18 and C16-18-unsatd., zinc salts consist of 90% natural fatty acids and 10% zinc.Fatty acids biodegrade readily according to the β-oxidation pathway including three major steps (activation in the cytosol, transport into mitochondria, β-Oxidation until the entire chain is cleaved into acetyl CoA units). Thus, stable degradation products are not being formed in the environment. Furthermore, breaking down by photons is not expected to be relevant for Fatty acids, C14-18 and C16-18-unsatd., zinc salts under typical environmental conditions.
