About this ingredient

Myristic acid is a saturated fatty acid (C14) naturally derived from plant and animal oils that functions as an emollient and surfactant in cosmetic formulations. It improves product texture, spreadability, and cleansing efficacy while enhancing formula stability and sensory feel. It is commonly used in soaps, cleansers, and skincare products.
