Applications
Pharmaceutical industry: HPMC is widely used as a binder, disintegrant, thickener, and suspending agent in tablets, capsules, and other pharmaceutical formulations. It can also be used as a coating agent and a sustained-release agent.
Food industry: HPMC is used in the food industry as a thickener, emulsifier, and stabilizer. It is commonly used in ice cream, yogurt, processed cheese, and other dairy products.
Construction industry: HPMC is used as a thickener, binder, and water retention agent in cement, mortar, and gypsum-based products. It improves workability, adhesion, and durability of these products.
Why use Hydroxypropylmethylcellulose (HPMC)?
- Non-toxic and safe to use
- Stable over a wide range of pH and temperature
- Cost-effective
- Provides excellent water retention
- Improves workability and adhesion in construction products
- Enhances thickness and stability in food products
Storage Condition
HPMC should be stored in a dry, cool place away from sunlight and heat. It should be kept in a tightly closed container to prevent moisture absorption. Once opened, the container should be resealed immediately after use to prevent clumping and caking. HPMC has a shelf life of approximately two years.
