Industrial Uses

1. Pharmaceuticals

  • Tablet Binder & Disintegrant: PVP is used in tablet formulations to help hold ingredients together and aid in disintegration for better drug absorption. It enhances the stability and shelf life of solid dosage forms.
  • Solubilizer for Poorly Soluble Drugs: Used in drug formulations to improve solubility and bioavailability of active pharmaceutical ingredients (APIs). Common in oral, injectable, and topical drug formulations.
  • Plasma Volume Expander: High molecular weight PVP (such as PVP K90) is used in intravenous fluids as a blood plasma volume expander for emergency treatments in cases of shock or blood loss.
  • Controlled-Release & Film-Coating Agent: Used in sustained-release and controlled-release drug formulations. Acts as a film-forming agent in coated tablets and capsules for protection against moisture.

2. Personal Care

  • Hair Care (Styling Gels, Hairsprays, Mousses): PVP forms a thin, flexible film on the hair, providing hold and styling benefits in hair gels, sprays, and mousses.
  • Skin Care & Moisturizers: Used in lotions, creams, and serums as a moisturizer and film-former to provide a soft, smooth feel.
  • Oral Care (Toothpaste & Mouthwash): Stabilizes active ingredients in toothpaste and mouthwash formulations, helping to prevent plaque buildup.
  • Makeup & Sunscreen: Acts as a film-forming agent in foundations, mascaras, and sunscreens, improving wear resistance.

3. Food & Healthcare Ingredients

  • Stabilizer & Thickener: PVP helps maintain the uniform dispersion of ingredients in food products, preventing separation. It is widely used in beverages, sauces, and dressings to enhance stability and consistency. This property is essential in sauces, gravies, soups, and desserts to improve mouthfeel.
  • Clarifying Agent: In the brewing and winemaking industries, PVP is used to remove tannins and polyphenols. This improves the clarity, taste, and shelf life of products like beer, wine, and fruit juices.
  • Emulsifier: PVP aids in blending water and oil-based ingredients, ensuring a smooth and homogeneous mixture. It is particularly useful in processed foods, dairy products, and confectionery.

4. Paints & Coatings

  • Paints & Industrial Coatings: PVP enhances adhesion and film durability in paints, varnishes, and protective coatings. Helps in anti-corrosion and waterproofing applications.
  • Printing Inks & Toners: Used as a dispersing agent to improve ink stability and viscosity control.
