Methyl cellulose is widely used as a thickening agent in various industries, including food, pharmaceuticals, and cosmetics. In the food industry, it is added to products like ice cream, sauces, and baked goods to improve texture and stability. In pharmaceuticals, it serves as a binder in tablets and a lubricant in eye drops. Additionally, it is utilized in construction materials such as adhesives and paints to enhance viscosity and water retention. Its ability to form gels when heated makes it valuable in controlled-release drug formulations and as a vegetarian alternative to gelatin in food products.
