HPMC is mainly used as a thickener, stabilizer, and film-forming agent in detergents and hand sanitizer formulations. In liquid detergents, it helps increase viscosity and improve product stability, preventing phase separation and providing a more convenient and controlled pouring or pumping experience. It also contributes to suspension stability of insoluble particles in some specialty detergent systems.
In hand sanitizers, HPMC is used to adjust gel consistency, improve skin feel, and maintain uniform dispersion of active ingredients such as alcohol. It helps form a smooth, non-sticky gel structure, enhances spreadability during application, and improves overall product aesthetics and user experience.
