One of the primary properties of HPMC 464 is its solubility in water. It readily dissolves in cold water, forming a clear and viscous solution. This solubility makes it an excellent choice for applications where a thickening or gelling agent is required. Additionally, HPMC 464 exhibits good film-forming properties, which makes it suitable for use in coatings and adhesives.

Another important property of HPMC 464 is its thermal stability. It can withstand high temperatures without undergoing significant degradation. This property makes it suitable for use in applications that involve exposure to heat, such as in the construction industry. HPMC 464 can be used as a binder in cement-based products, where it enhances the workability and adhesion of the mixture.

Furthermore, HPMC 464 has excellent rheological properties. It imparts a pseudoplastic behavior to solutions, meaning that their viscosity decreases with increasing shear rate. This property is particularly useful in applications where controlled flow and spreadability are desired, such as in paints and coatings. HPMC 464 also acts as a thickener, providing stability and preventing sagging or dripping.

In the pharmaceutical industry, HPMC 464 is widely used as an excipient in drug formulations. It can be used as a binder, disintegrant, or controlled-release agent in tablets and capsules. Its solubility in water allows for easy dissolution and release of the active ingredient. Moreover, HPMC 464 is non-toxic and hypoallergenic, making it safe for oral administration.

In the food industry, HPMC 464 is used as a food additive and thickening agent. It can be found in a variety of products, including sauces, dressings, and baked goods. HPMC 464 improves the texture and stability of these products, providing a smooth and creamy consistency. It is also resistant to enzymatic degradation, ensuring the longevity of the food product.

In the personal care industry, HPMC 464 is commonly used in cosmetic formulations. It acts as a thickener, emulsifier, and stabilizer in creams, lotions, and gels. HPMC 464 enhances the spreadability and moisturizing properties of these products, leaving the skin feeling soft and hydrated. Its film-forming properties also contribute to the longevity of the cosmetic product on the skin.

In conclusion, Hydroxypropyl Methylcellulose 464 is a versatile compound with a wide range of properties and uses.
