Glyceryl Stearate (Glyceryl Stearate)

Glyceryl Stearate is an ester of glycerin and stearic acid widely used in cosmetic formulations as an emollient, co-emulsifier, and texture/consistency agent. It helps stabilize oil-in-water emulsions by supporting droplet structure, while also building viscosity and delivering a smooth, creamy sensorial profile with improved slip and spreadability. In addition to its emulsification support, it contributes to a softer, more conditioned after-feel and can help reduce the perception of greasiness by structuring the oil phase. Glyceryl Stearate is commonly found in facial and body creams, lotions, cleansing creams, sunscreens, and some hair-conditioning emulsions, often paired with fatty alcohols and primary emulsifiers to fine-tune stability and texture. Use level and performance are formulation-dependent and typically optimized according to oil load, target viscosity, and the desired final skin feel.
