What it is
Glyceryl myristate is a monoester of glycerin and myristic acid, a saturated medium-to-long-chain fatty acid. It functions as a nonionic co-emulsifier and emollient, helping to stabilize emulsions and impart a smooth feel. It is often used as a structuring or texture-modifying lipid.
Safety & warnings
Glyceryl myristate is generally well tolerated in cosmetic use. As a saturated fatty-acid monoester it can contribute to a richer, more occlusive feel and, like many fatty lipids, may be a consideration in heavy formulas for those prone to clogged pores. It is not a recognized fragrance allergen.
Origin & sourcing
It is produced synthetically by esterifying glycerin with myristic acid, which is commonly sourced from plant oils such as coconut or palm.
Questions everyone asks
What role does glyceryl myristate play in a formula?
It works as a co-emulsifier and emollient, helping keep the emulsion stable while contributing a smooth, conditioned feel to the product.
Is glyceryl myristate plant-derived?
It can be, since the myristic acid used to make it is often obtained from plant oils such as coconut or palm, though the ester itself is produced synthetically.
