Polyvinylpyrrolidone (PVP) K30 is a highly versatile polymer used across numerous industries, from pharmaceuticals and cosmetics to various industrial applications. Understanding its properties, proper handling, and safety measures is crucial for effective and safe utilization. Ningbo Inno Pharmchem Co., Ltd. provides essential information on PVP K30.

Physical and Chemical Properties:
PVP K30 is typically a white to light yellow, hygroscopic, amorphous powder. Its key characteristic is its excellent water solubility, along with solubility in many polar organic solvents like alcohols and amines, while being insoluble in non-polar solvents such as hydrocarbons and ketones. Its molecular weight, indicated by the K-value of 30, influences its viscosity and adhesive properties. It forms clear, glossy films when dried from solution and possesses good chemical stability, remaining relatively unaffected by acids, salts, and moderate heat. Its pH in aqueous solution is typically neutral to slightly acidic.

Handling and Storage:
Due to its hygroscopic nature, PVP K30 should be stored in tightly sealed containers in a cool, dry place to prevent moisture absorption, which can lead to caking and affect its flowability. When handling, it is advisable to use appropriate personal protective equipment (PPE), such as gloves, safety glasses, and a dust mask, especially when dealing with large quantities or in powdered form, to avoid inhalation and skin or eye irritation. Proper ventilation in the work area is also recommended.

Safety Considerations:
PVP K30 is generally recognized as safe (GRAS) by regulatory bodies for many applications, particularly in pharmaceuticals and cosmetics. It is considered physiologically inert, meaning it does not typically react with biological systems. However, as with any chemical, direct contact should be minimized. In case of inhalation, move to fresh air. For skin contact, wash with soap and water. If it gets into the eyes, rinse thoroughly with water. Ingestion should be followed by drinking water, but medical attention should be sought if any adverse reactions occur. The primary risks are associated with dust inhalation or eye contact. Always refer to the specific Safety Data Sheet (SDS) for detailed handling and emergency procedures.
