INCI: Cetearyl Olivate
Cetearyl olivate is an ester of cetearyl alcohol and the fatty acids derived from olive oil. It functions as an emulsifier, blending water and oil phases together in skincare formulations. Uniquely, it generates liquid crystal structures that closely mimic the lipid architecture of the stratum corneum, giving it barrier-repairing and moisturising properties beyond simple emulsification.
