NINGBO INNO PHARMCHEM CO.,LTD. offers this guide to provide a comprehensive understanding of Polyvinylpyrrolidone K90 (PVP K90), a versatile polymer essential for formulators and manufacturers across various sectors. Grasping its properties and best practices for its use can significantly enhance product development and efficacy.

PVP K90 is a water-soluble, non-ionic polymer characterized by its high molecular weight and excellent binding, film-forming, and dispersing capabilities. Typically supplied as a white or off-white powder, it is known for its hygroscopic nature, meaning it can absorb moisture from the atmosphere. Proper storage in tightly sealed containers, away from humidity, is crucial to maintain its free-flowing nature and prevent clumping.

For pharmaceutical applications, PVP K90 is a highly regarded excipient. Its primary role as a tablet binder ensures the mechanical strength and integrity of dosage forms. Formulators often utilize its ability to form solid dispersions, which can improve the solubility and bioavailability of poorly water-soluble drugs. When purchasing for pharmaceutical use, it is critical to source PVP K90 that meets stringent pharmacopoeial standards (e.g., USP, EP) for purity and safety. NINGBO INNO PHARMCHEM CO.,LTD. ensures compliance with these essential regulatory requirements.

In the cosmetic industry, PVP K90 is a key ingredient, especially in hair styling products. Its film-forming properties provide excellent hold, manageability, and shine without stickiness or flaking. Formulators can leverage its viscosity-enhancing and stabilizing capabilities to create desirable textures and product stability in lotions, creams, and hair care products. The compatibility of PVP K90 with a wide array of cosmetic ingredients further expands its utility, enabling the creation of sophisticated formulations.

Industrially, PVP K90 is valued for its adhesive properties in water-based glues and its role as a dispersant and stabilizer in coatings, inks, and textiles. Its ability to improve the flow properties of liquids and ensure uniform distribution of pigments makes it indispensable in these sectors. When specifying PVP K90 for industrial use, considering the required viscosity and adhesive strength is key to selecting the appropriate grade and concentration.

Handling PVP K90 requires attention to its hygroscopic nature. While it is stable under normal storage conditions, exposure to high humidity can lead to caking. Manufacturers should ensure appropriate environmental controls during production and storage. The polymer is generally considered safe and physiologically inert, making it suitable for a broad range of consumer and industrial products.
