MHEC also enhances the water retention capacity of cement-based materials, allowing for better hydration of cement particles and improved mechanical strength of the final product.
3. Food Industry In food applications, high viscosity HPMC serves as a functional ingredient that acts as a stabilizer, emulsifier, and thickening agent. It is often used in sauces, dressings, and gravies to enhance viscosity and improve mouthfeel without altering the flavor. Its properties also help in the formulation of gluten-free products, providing desirable texture and consistency.
- Soluble in cold water
For instance, low viscosity HPMC may be chosen for applications requiring a thin solution that flows easily, such as in sprayable formulations. Conversely, high viscosity grades are favored in products like gels and creams, where a thicker consistency is required to enhance stability and texture.
Over the years, gelatin capsules have been the preferred choice of hundreds of pharmaceutical and nutraceutical industries and are forecasted to remain relatively popular. However, as more consumers are demanding “natural” products, vegetable-based capsules have begun to penetrate leading markets in Western Europe, Canada and the United States.
- When HEC is dissolved in water, its viscosity increases as the concentration increases. This means that higher concentrations of HEC result in thicker solutions that are more resistant to flow. This property makes HEC an ideal additive in many applications where viscosity control is crucial, such as in the production of paints, adhesives, and personal care products.
- In addition to enhancing workability, HPMC also serves as a good binder in construction materials. It helps the different components of a mix stick together, preventing segregation and improving the strength of the final product. This makes it an essential ingredient in tile adhesives, cement renders, and gypsum-based plasters, among others.
- After mercerization, the cellulose is treated with ethylene oxide to introduce hydroxyethyl groups onto the cellulose backbone. This reaction results in the formation of hydroxyethyl cellulose. The degree of substitution of hydroxyethyl groups can be controlled during the manufacturing process to tailor the properties of HEC for specific applications.
