Polyglyceryl-4 Oleate is a natural, COSMOS-approved emulsifier derived from vegetable glycerin and fatty acids, often sourced from sunflower or other plant oils. It is designed to bring oil and water together in a way that feels gentle, fluid, and skin-compatible.

Unlike harsher surfactants, this ingredient allows oil-based cleansers to rinse clean while still respecting the skin’s natural barrier. It creates a soft, milky transformation when water is introduced, lifting away impurities without leaving the skin stripped or tight.

In M. Carya formulations, Polyglyceryl-4 Oleate plays a quiet but essential role. It supports the cleansing process while preserving the integrity of the skin, allowing the formula to feel both effective and refined.
