Polyvinylpyrrolidone, commonly known as Povidone or PVP, is a highly versatile polymer widely recognized for its unique properties and extensive applications, particularly within the pharmaceutical and cosmetic industries. Identified by CAS number 9003-39-8, this material serves as a critical raw material in numerous formulations.

Available in various grades, including PVP K30 and PVP K90, Povidone presents as a white powder. Its key characteristics include excellent solubility in water and a broad range of organic solvents, good hygroscopicity, exceptional film-forming capability, complexing ability, and physiological compatibility. These properties make it an indispensable ingredient for enhancing the performance and stability of diverse products.

In the pharmaceutical sector, Povidone K series functions primarily as a superior excipient. It is extensively used as a binder for tablets, improving their mechanical strength and integrity. Furthermore, it acts as a dissolving assistant for injections, a flow assistant for capsules, and a dispersant for liquid medicines and stains. Its stabilizing properties are crucial for enzymes and heat-sensitive drugs. It also serves as a coprecipitant for poorly soluble active pharmaceutical ingredients (APIs), and as a lubricator and antitoxic assistant in eye formulations. Its utility spans across more than a hundred different drug formulations, highlighting its importance in modern medicine.

For the cosmetics industry, PVP K series is valued as a film-forming agent, viscosity enhancer, lubricator, and adhesive. It is a fundamental component in hair care products such as hair sprays, mousses, gels, lotions, solutions, hair-dying reagents, and shampoos. Beyond hair care, it is incorporated into skin care products, eye makeup, lipsticks, deodorants, sunscreens, and dentifrice, contributing to product texture, hold, and stability.

Beyond these major applications, Povidone also finds use as an assistant in other industries, including paints and coatings, plastics and resins, adhesives, glass fiber manufacturing, films, inks, TV tubes, detergents, biocides, tabulating processes, and textile dyeing and printing.

The material boasts a high purity level, typically exceeding 99%, ensuring its suitability for sensitive applications. Proper storage conditions, such as drying and airproof environments, are recommended to maintain its quality and shelf life, which is typically three years. Packaging is commonly provided in 25 kg fiber drums.
