Science
Mechanism of Action
As a modified starch, Glyceryl Starch enhances the texture and feel of skincare formulations, acting as a thickener, texturizer, and mild absorbent. The incorporated glycerol component actively draws moisture from the environment, delivering hydration to the skin. This unique synergy, driven by hydrogen bonding between glycerol and the starch matrix, also contributes to increased flexibility and water solubility within the formulation.
