Isoamyl Laurate

Brief Description

Isoamyl Laurate is a natural, plant-derived ester of isoamyl alcohol and lauric acid. It is commonly used as an emollient, texture enhancer, and silicone alternative in skincare and haircare products. This lightweight, biodegradable ingredient imparts a silky, non-greasy feel to formulations and improves spreadability while reducing tackiness.
