Castor Isostearate Beeswax Succinate
What is Castor Isostearate Beeswax Succinate?
Castor Isostearate Beeswax Succinate is a synthetic ester created by chemically combining fatty acids from hydrogenated castor oil, isostearic acid derived from vegetable oils, alcohols from beeswax, and succinic acid. This results in a waxy, thick material commonly used in anhydrous cosmetics like lipsticks, foundations, and mascaras. In formulations, it acts as an emollient by forming a protective film on the skin's surface, which helps retain moisture and imparts a smooth, non-greasy feel. It also functions as a viscosity builder, stabilizing product consistency and improving spreadability without altering color or scent. Derived partly from natural sources, it supports long-wear properties in makeup while maintaining skin barrier integrity during application.
