2. Product Applications

PVP K30 serves as a versatile excipient and functional additive across multiple industries:

Pharmaceutical Industry

• Binder for Tablets & Granules: Enhances particle aggregation and tablet hardness, suitable for direct compression or wet granulation

• Solubilizer for Injectables: Improves solubility of poorly water-soluble drugs via complexation

• Stabilizer for Sensitive Formulations: Protects enzymes and heat-labile drugs from degradation

• Film Former in Ophthalmic Solutions: Forms a protective layer on ocular surfaces with excellent biocompatibility

• Disinfectant Component: Combined with iodine to form PVP-I, a broad-spectrum antiseptic

Other Industries

• Cosmetics: Thickener and film former in shampoos, toothpastes, and contact lens solutions

• Food & Beverage: Fining agent for white wine and beer, binder in food coatings

• Technical Applications: Additive for batteries, ceramics, inks, and inkjet paper to improve processability
