Hydroxypropylmethylcellulose (HPMC) is a versatile, non-toxic cellulose ether widely used as a thickening, stabilizing, and film-forming agent across multiple industries. In pharmaceuticals, it serves as a binder, coating material for tablets, and controlled-release agent to enhance drug stability and delivery. In the food industry, it functions as an emulsifier and thickener in products such as sauces, dressings, ice creams, and other dairy items, improving texture, consistency, and shelf life. In construction, it is incorporated into cement-based mortars and plasters to enhance water retention, workability, adhesion, and anti-sagging properties. In personal care and cosmetics, including shampoos, lotions, and creams, it provides viscosity control and formulation stability. Additionally, in paints, coatings, and adhesives, it acts as a rheology modifier to improve viscosity, dispersion, and application properties. Its biocompatibility and multifunctionality make it essential in these specialized applications.
