Polyvinylpyrrolidone (PVP), commonly referred to by its K-value designation, is a synthetic polymer that has garnered significant attention across various industries due to its unique properties. Among the different grades, PVP K30 is one of the most frequently utilized, offering a balanced profile of viscosity, molecular weight, and performance characteristics. Ningbo Inno Pharmchem Co., Ltd. is a reliable source for high-quality PVP K30, and understanding its properties is key to unlocking its full potential in diverse applications.

PVP K30 is characterized by its K-value, which signifies its viscosity in aqueous solution, and for K30, this typically ranges from 27.0 to 32.4. Its molecular weight generally falls between 45,000 to 58,000 g/mol. Physically, it appears as a white to light yellow, amorphous powder. A notable property of PVP K30 is its hygroscopicity, meaning it readily absorbs moisture from the atmosphere. It exhibits excellent solubility in water and a range of organic solvents, including ethanol, isopropanol, and chloroform, making it highly adaptable for various formulation processes. The polymer is generally stable, with a shelf life of approximately three years when stored correctly.

The pharmaceutical industry extensively relies on PVP K30 as a binder in tablet formulations, contributing to the tablet's mechanical strength and ensuring it remains intact during handling and transport. It also acts as a dissolving assistant for injections and a stabilizer for suspensions, improving the bioavailability of poorly soluble drugs. In pharmaceutical manufacturing, selecting the right grade of PVP is crucial, and K30 offers a versatile balance for many common applications. For instance, using PVP K30 as a binder for tablets ensures good compressibility and flowability of the granules.

Beyond pharmaceuticals, PVP K30 is a valuable cosmetic ingredient. It functions as a film-forming agent, viscosity enhancer, and stabilizer in hair care products like hairsprays and gels, providing hold and texture. In skincare, it can improve the feel and hydration of formulations. Industrially, PVP K30 serves as a dispersant and binder in paints, coatings, and inks, enhancing pigment distribution and film integrity. Its adhesive qualities are also utilized in remoistenable adhesives. Ningbo Inno Pharmchem Co., Ltd. ensures that the PVP K30 supplied adheres to strict quality standards, enabling consistent performance across these varied sectors. Understanding the specific properties of PVP K30 allows formulators to effectively leverage this adaptable polymer to achieve desired product outcomes.
