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, renders, and tile adhesives, ensuring better performance and durability. In pharmaceuticals, HPMC serves as a coating agent for tablets, providing controlled release of active ingredients and enhancing drug stability. It is also used as a thickening and stabilizing agent in various personal care products, such as shampoos, lotions, and creams, to improve texture and consistency. In the food industry, HPMC acts as an emulsifier, thickener, and stabilizer in products like sauces, dairy items, and baked goods, enhancing their quality and shelf life. Additionally, it is employed in the production of artificial tears and contact lens solutions due to its lubricating and moisture-retaining properties.
