Hydroxypropylmethylcellulose (HPMC) is widely used as a thickening, binding, and film-forming agent in various industries. In pharmaceuticals, it is employed as an excipient in tablets to control drug release and improve solubility. It also acts as a stabilizer in ophthalmic solutions and topical gels. In construction, HPMC is added to cement-based products like mortars and tile adhesives to enhance workability, water retention, and adhesion. In food, it serves as an emulsifier, thickener, and stabilizer in products like sauces, dairy, and baked goods. Additionally, it is used in cosmetics for its moisturizing and texture-enhancing properties in creams, lotions, and shampoos. Its versatility and safety make it a valuable ingredient across multiple applications.
