Isostearyl Palmitate
What is Isostearyl Palmitate?
Isostearyl palmitate is an ester of isostearyl alcohol and palmitic acid. It is a synthetic ingredient created through esterification, a chemical reaction between an alcohol and an acid that usually requires a catalyst.
This ingredient is often used in cosmetics, especially in makeup, due to its ability to act as an emollient. It helps to spread formulas smoothly on the skin, providing a silky feel. Most studies suggest it is generally safe for topical use, though the research on long-term effects is limited.
