Hydroxypropylmethylcellulose is widely used as a thickening agent in various industries, including food, pharmaceuticals, and cosmetics. In the food industry, it enhances the texture and stability of products like sauces, dressings, and baked goods. In pharmaceuticals, it serves as a binder, coating agent, and controlled-release matrix in tablets and capsules. Additionally, it is a key ingredient in eye drops and artificial tears due to its lubricating and moisturizing properties. In construction, it is added to cement-based materials to improve water retention and workability. Its versatility also extends to personal care products, where it acts as a stabilizer and emulsifier in lotions, creams, and shampoos.
