Myristyl Myristate

Benefits

Softening

What is Myristyl Myristate?

Myristyl myristate forms through esterification of myristic acid and myristyl alcohol, fatty components often extracted from coconut or palm kernel oils, with synthetic production also common. It serves primarily as an emollient in skincare formulations like moisturizers, creams, and makeup products. Functionally, it deposits a soft, lubricious layer on the skin, mimicking natural sebum to enhance smoothness and reduce friction during application. This layer also aids in preventing transepidermal water loss by creating a subtle barrier. As an opacifying agent, it scatters light to give products a creamy, uniform appearance, hiding inconsistencies in texture or color. Its mild, neutral profile makes it versatile for leave-on products, where it contributes to a velvety after-feel without tackiness, supporting overall formula stability and sensory appeal.
