Hydroxypropyl Starch (CAS 9049-76-7) is a modified, etherified starch supplied as a white or slightly yellowish powder, a Technical Grade rheology modifier that provides water retention and sag resistance in cementitious construction materials and acts as a plant-based texturizer in personal care lotions and creams. In the cosmetics sector, it serves as a Plant-Based texturizer that offers a silky, non-greasy skin feel in lotions and creams. It exhibits high stability against electrolytes and shear, outperforming natural starches in complex industrial formulations. The product functions as a powerful thickening agent that enhances the workability of dry-mix mortars and adhesives. Its modified structure prevents enzymatic degradation and ensures consistent viscosity across a wide pH range.
