Polyvinylpyrrolidone K30 (PVP K30), with CAS number 9003-39-8, is a water-soluble linear polymer synthesized from monomer through free radical polymerization, featuring excellent solubility, film-forming ability, complexation capacity, and biocompatibility. Unlike many other polymers, PVP K30 exhibits remarkable versatility due to its non-ionic nature, which allows it to blend seamlessly with a wide range of substances without causing undesirable reactions. Its chemical structure is stable under normal use conditions, including a wide range of temperatures and pH values, making it adaptable to various production environments and application scenarios.

This stability also ensures that PVP K30 maintains its core properties throughout the production process and during the service life of the end products. PVP K30 is available in three main grades—industrial, pharmaceutical and cosmetic—each tailored to meet the specific requirements of different application fields, with targeted quality indicators and performance characteristics to ensure optimal performance in respective scenarios. Each grade undergoes strict testing to align with the unique standards of its intended industry, ensuring that it delivers consistent and reliable results for every customer

Pharmaceutical Grade PVP K30 

Produced under strict quality control standards that comply with GMP requirements, Pharmaceutical Grade PVP K30 meets the requirements of mainstream pharmacopoeias such as USP, EP and ChP. It is a multifunctional pharmaceutical excipient widely used in solid, liquid and semi-solid dosage forms, with high purity, low impurity content and stable performance.

Typical applications include: serving as a binder for tablets and granules, which can improve the forming effect and mechanical strength of the products, reduce the friability of tablets and ensure the uniformity of dosage; acting as a solubilizer and dispersant for injections, oral liquids and topical preparations, helping to improve the solubility and dispersibility of poorly soluble drugs and enhance the bioavailability of preparations; being used as a film-former for tablet coating, which can form a smooth and uniform coating film to protect the active ingredients from external factors, also functioning as a flow aid for capsule filling and a cooprecipitation agent to enhance the dissolution of poorly soluble active pharmaceutical ingredients, further expanding the application scope of drugs.

Cosmetic Grade PVP K30

Cosmetic Grade PVP K30 has consistent purity, mild performance and no irritation to human skin and hair, which is in line with the safety standards of cosmetic raw materials. It is widely adopted in various personal care and cosmetic formulations, playing an important role in improving product performance and user experience.

Its main uses include: serving as a film-former in hair styling products such as hair gels, mousses and sprays, which can form a flexible and breathable film on the hair surface, providing lasting shaping effect with lightweight texture, without making the hair stiff or sticky; acting as a humectant and viscosity modifier in skin care lotions, creams and sunscreens, which can absorb and lock moisture, improve the spreadability and moisture retention of products, make the skin feel soft and smooth after use; being used as a stabilizer and thickener in shampoos, conditioners and color cosmetics, which can enhance the uniformity and stability of products, prevent stratification or precipitation, and improve the texture and use effect of cosmetics.

Industrial Grade PVP K30

Industrial Grade PVP K30 features good compatibility, strong process stability and cost-effectiveness, which can support various industrial manufacturing processes and improve production efficiency and product quality.

Its main applications cover multiple industrial fields: in the water treatment industry, it is used as a porogen and modifier in water treatment membranes, which can adjust the pore structure of the membrane, boost porosity and permeability, and improve the treatment effect of water; in the new energy field, it functions as a dispersant in the electrode paste of lithium-ion batteries, which can effectively reduce the agglomeration of active materials, improve the uniformity of the paste and enhance the electrochemical performance of batteries; in the coating and ink industry, it acts as a binder and stabilizer in coatings, inks and dyestuffs, which can improve the color uniformity and adhesion of products, enhance the film-forming performance and durability; in the textile and paper industry, it is used as an adhesive component in textiles, paper and printing auxiliaries, which can enhance the strength and surface properties of products, improve the wear resistance and printability of textiles and paper.

As a versatile polymer material, PVP K30 dissolves readily in water and many organic solvents, with stable physical and chemical properties that support reliable performance in continuous production. Our graded PVP K30 products are produced with mature production technology and strict quality inspection, which can provide consistent quality and scalable applications for customers in pharmaceutical, cosmetic and industrial fields, helping customers optimize production processes and improve product competitiveness.
