Hydroxypropylmethylcellulose (HPMC) is widely used in the construction industry as a key additive in cement-based products. It improves workability, water retention, and adhesion in mortars, tile adhesives, and renders. In pharmaceuticals, it serves as a binder, thickener, and film-forming agent in tablets, coatings, and ophthalmic solutions. In the food industry, HPMC acts as a stabilizer, emulsifier, and thickening agent in products like sauces, dairy, and baked goods. It is also utilized in cosmetics for its moisturizing and film-forming properties in creams, lotions, and hair care products. Additionally, HPMC is employed in ceramics, paints, and coatings to enhance texture and performance.
