Glyceryl stearate is an organic compound sourced from glycerin and stearic acid, both of which can be sourced from vegetable oils. It's a versatile ingredient found in a wide range of skincare products like creams, lotions, moisturizers, sunscreens and serums. It serves as an emulsifier that helps to blend oil and water-based ingredients and improve the overall texture and stability of these formulas. It can also improve the spreadability and absorption of skincare products to ensure even application and better delivery of active ingredients to skin.
