Pentaerythrityl Tetracaprylate/Tetracaprate

What is Pentaerythrityl Tetracaprylate/Tetracaprate?

Pentaerythrityl Tetracaprylate/Tetracaprate is a synthetic tetraester produced by combining pentaerythritol, a polyhydric alcohol, with caprylic and capric fatty acids typically sourced from coconut or palm kernel oils. It falls into the emollient and skin-conditioning category in cosmetic formulations like lotions, creams, and sunscreens. This ingredient works by forming a thin, lubricious layer on the skin that mimics natural sebum, promoting even distribution and a silky feel while aiding in moisture retention through improved barrier function. Its unique branched molecular structure provides excellent solubility in oils, enabling it to thicken and stabilize emulsions without adding greasiness, which supports better suspension of active ingredients and enhances overall product stability and user experience across various textures.
