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, enhancing their performance and durability. In pharmaceuticals, HPMC acts as a binder, thickener, and film-forming agent in tablets, capsules, and ophthalmic solutions, ensuring controlled drug release and stability. In the food industry, it serves as an emulsifier, thickener, and stabilizer in products like sauces, dairy, and baked goods, improving texture and shelf life. Additionally, HPMC is utilized in personal care products, such as shampoos and lotions, for its thickening and moisturizing properties. Its versatility and safety make it a valuable ingredient across multiple industries.
