NINGBO INNO PHARMCHEM CO.,LTD. delves into the scientific underpinnings of Povidone K90 (PVP K90), exploring the molecular characteristics that grant it such remarkable versatility in industrial applications. This non-ionic, water-soluble polymer, a homopolymer of N-vinylpyrrolidone, is a marvel of polymer chemistry, offering a unique blend of functional attributes.
The K value of Povidone K90, typically ranging from 81 to 97.2, signifies its relatively high molecular weight (often around 1,000,000 to 1,500,000 g/mol). This high molecular weight is directly responsible for its superior binding strength and its efficacy as a thickener. The polymer chains exhibit strong intermolecular forces, allowing them to effectively aggregate and form viscous solutions or gels, a property highly valued in both cosmetic and pharmaceutical contexts.
Povidone K90's solubility is another key characteristic. It readily dissolves in water and a variety of organic solvents, including alcohols, amines, and chlorinated hydrocarbons. This broad solubility profile allows for its incorporation into diverse formulations, whether in aqueous or non-aqueous systems. The ability to buy Povidone K90 and easily integrate it into different processing methods significantly simplifies product development.
The film-forming ability of Povidone K90 is attributed to its molecular structure, which allows it to create smooth, clear, and adherent films upon drying. These films are known for their glossiness and flexibility, making them ideal for hair styling products where they provide hold without stiffness. In pharmaceuticals, these films can be used for tablet coatings, offering protection and aiding in controlled release.
Physiologically, Povidone K90 is considered inert and has low toxicity. This safety profile, coupled with its excellent biocompatibility, makes it a preferred choice for applications that involve direct contact with the human body, such as in cosmetics and pharmaceuticals. Its hygroscopic nature also contributes to its moisturizing capabilities, as it can attract and retain water molecules.
The chemical stability of Povidone K90 under various conditions further enhances its utility. It is resistant to acids, salts, and moderate heat, ensuring that it performs reliably in a wide range of product formulations. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Povidone K90 adheres to strict quality standards, guaranteeing consistent molecular weight and purity for optimal performance in your applications.
