In the construction industry, methylcellulose is commonly used as a water-retaining agent and retarder in cement mortar. It effectively improves the water retention of mortar, preventing excessive evaporation and thus improving its workability and hardened strength. Simultaneously, methylcellulose acts as a retarder, extending the setting time of the mortar and providing more working time during construction.
In the pharmaceutical industry, methylcellulose also has important applications. It can be used as an excipient in the preparation of solid dosage forms such as tablets and capsules. Methylcellulose can also be used as a viscosity modifier in ophthalmic drugs, improving drug stability and bioavailability.
In the food and cosmetic industries, methylcellulose plays a similarly important role. In the food industry, it acts as a thickener, stabilizer, and emulsifier, improving the taste and texture of food. In cosmetics, methylcellulose acts as a film-forming agent, providing good adhesion and durability.
