What is PCA Glyceryl Oleate?

PCA Glyceryl Oleate is a cosmetic ingredient formed by combining pyrrolidone carboxylic acid (PCA), a naturally occurring humectant in the skin's moisturizing factor, with glyceryl oleate, an ester from glycerol and oleic acid sourced from plant oils. It falls into the skin conditioning category, appearing in creams, lotions, and serums. In products, it functions as an amphiphilic agent, blending water-attracting humectant properties with oil-compatible emolliency. This enables deeper moisture penetration, formation of a breathable barrier to limit water evaporation, and enhancement of product texture for a smooth, non-sticky finish. Its structure supports emulsion stability, making it ideal for leave-on formulations targeting hydration without heaviness.
