- 2. Pharmaceutical Industry HPMC is used as a binder and disintegrant in tablets and capsules, as well as a coating agent for oral sustained-release formulations.
- In addition to its technical advantages, HPMC is also environmentally friendly. Being a derivative of plant-based cellulose, it is non-toxic, biodegradable, and does not pose any significant environmental concerns. This aligns with the growing emphasis on sustainability in the construction sector.
- Another significant advantage of VAE redispersible powder is its ease of use. The powder can be easily mixed with water to form a smooth, uniform dispersion, eliminating the need for complex mixing equipment or skilled operators. This simplifies the application process and reduces the risk of errors or inconsistencies in the final product.
- The food industry also utilizes HEC for its emulsifying and thickening capabilities
- Derived from natural cellulose, HEC is a non-toxic, biodegradable, and environmentally friendly polymer. It is synthesized by the chemical modification of cellulose, primarily through ethoxylation, resulting in a product with unique rheological characteristics. The hydroxyethyl groups impart solubility in water, making it an ideal choice for numerous applications where thickening, stabilizing, or suspending agents are required.
- Acetone and ethyl acetate, being polar aprotic solvents, can dissolve HPMC effectively due to their ability to disrupt the intermolecular forces within the polymer structure
hpmc solubility in organic solvents. The solubility in these solvents increases with an increase in temperature, following the general rule of thermodynamics for solute-solvent interactions.
