Povidone K90 (PVP K90), a synthetic water-soluble polymer, is characterized by a unique set of chemical properties that underpin its widespread use across industries. NINGBO INNO PHARMCHEM CO.,LTD. delves into the chemistry and safety of this versatile compound.

Chemically, Povidone K90 is a homopolymer of N-vinylpyrrolidone. Its structure imparts excellent solubility in water and a variety of organic solvents, including alcohols, amines, and halohydrocarbons, though it is insoluble in acetone and ether. This broad solubility profile makes it highly adaptable for use in diverse formulations and manufacturing processes. Its non-ionic nature further enhances its compatibility with a wide range of other chemical substances, minimizing potential interactions and ensuring formulation stability.

PVP K90 is known for its hygroscopic nature, meaning it readily absorbs moisture from the environment. While this property can be beneficial in some applications (like moisturizers), it also requires careful storage in airtight containers to maintain product integrity. The polymer is generally stable under normal storage conditions, but it is sensitive to strong oxidizing agents and light. Its melting point is above 300°C, indicating significant thermal stability for many applications.

From a safety perspective, Povidone K90 is highly regarded. It is considered biocompatible and physiologically inert, exhibiting low toxicity. The U.S. Food and Drug Administration (FDA) has designated it as Generally Recognized As Safe (GRAS) for many uses. It is not absorbed from the gastrointestinal tract when ingested orally, and it generally has no irritant effect on the skin or eyes, nor does it cause sensitization. This favorable safety profile makes it an ideal choice for pharmaceutical and cosmetic products. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict quality control measures to ensure the safety and purity of our Povidone K90 offerings.
