What It Does
Caprylic acid is a naturally occurring saturated medium-chain fatty acid (C8:0) derived primarily from coconut oil and palm kernel oil, where it exists as a minor triglyceride component. It is valued in cosmetic formulations for its mild, broad-spectrum antimicrobial activity against bacteria and fungi, making it a popular multifunctional ingredient in preservative systems and skin-balancing products. Formulators also choose it for its ability to slightly acidify formulations, support the skin's natural acid mantle, and contribute a lightweight, non-greasy skin feel as an emollient.
