Polyglyceryl-10 Myristate

Polyglyceryl-10 Myristate is a plant-derived cosmetic ingredient made by combining myristic acid (a fatty acid often sourced from coconut or palm) with polyglycerin. In formulas, it mainly acts as an emulsifier and surfactant, helping oil and water mix smoothly so creams, cleansers, and lotions stay stable and feel pleasant on the skin. It can also contribute a light, silky slip and a more even texture in products.

For skin, this ingredient is most useful in cleansing products, where it helps lift away makeup, sunscreen, and excess oil without making the formula feel harsh. In moisturizers and leave-on products, it supports a smooth, spreadable feel and can help ingredients distribute evenly. Hair products may use it for similar reasons: to improve texture and help oily and watery ingredients blend well.

Who may like it? People who prefer milder, more modern emulsifiers in gentle cleansers or lightweight creams. Caveat: as with any ingredient, individual sensitivity is possible, especially in rinse-off products with multiple surfactants. It’s not a standout “treatment” ingredient on its own, but it plays an important behind-the-scenes role in how a formula performs.
