About
An ester of isooctyl alcohol, lactic acid and tall oil fatty acids — a lightweight emollient with renewable sourcing but batch variability.
Isooctyl lactoyl tallate is a branched-chain ester built from isooctyl alcohol esterified with the lactate ester of tall oil fatty acids (the C18 unsaturated fatty acid fraction recovered from kraft pulping). It functions as a lightweight skin-conditioning emollient with a silky, non-greasy slip. Tall oil fatty acids are renewable but naturally variable; residual rosin (abietic acid) derivatives in insufficiently refined grades can act as contact sensitizers. There is no specific CIR monograph for this precise structure, though related tallate esters have been reviewed with broadly favorable conclusions when rosin content is controlled. Branched isooctyl alcohol-derived esters have thinner long-term data than linear octyl.
