Methyl cellulose is widely used in the construction industry as a thickener and water retention agent in cement-based products like mortars and tile adhesives. It improves workability and prevents premature drying. In the food industry, it acts as a stabilizer, emulsifier, and thickener in products such as ice cream, sauces, and baked goods. In pharmaceuticals, it is used as a binder in tablet formulations and as a lubricant in eye drops. Additionally, it serves as a key ingredient in personal care products like shampoos and lotions for its viscosity-modifying properties. Its ability to form gels when heated makes it useful in controlled-release drug delivery systems and as a vegetarian alternative to gelatin in food applications.
