About
Tall oil fatty acids esterified with isooctyl alcohol — a light emollient. Quality depends on removing rosin-acid residues.
Isooctyl tallate is an ester of branched-chain isooctyl alcohol with the fatty acid fraction of tall oil (mainly oleic and linoleic acid, recovered as a kraft pulping byproduct). It functions as a light, spreadable emollient. Like other tallate esters, the main quality concern is residual rosin (abietic-type) acids, which are known contact sensitizers; properly refined cosmetic grades should have these below detection. No dedicated CIR monograph, but related fatty-acid esters have broadly favorable safety records. The ingredient is also used heavily outside cosmetics as a plasticizer and lubricant.
