Glyceryl Caprylate

Glyceryl Caprylate is a monoester formed from glycerin and caprylic acid (C8 fatty acid), typically derived from coconut or palm kernel oil. It serves a dual role in cosmetic formulations as both a mild co-emulsifier for oil-in-water systems and a multifunctional preservative booster with antimicrobial activity against bacteria and fungi. Formulators favor it for natural and eco-certified products because it provides gentle preservation enhancement while maintaining skin compatibility, allowing for reduced levels of traditional preservatives or supporting preservative-free claims in certain formulations.
