The solubility, surface activity, film-forming property, hygroscopicity, chemical stability, physiological inertness and safety of povidone powder all enable it to be widely used in many industries. Nowadays, it can be seen in the medical field, cosmetic field and water treatment field. At the same time, povidone still publishes more than 200 papers every year to show its current status and prospects for continued development.
Good bonding ability: It can be used as a binder and stabilizer in pharmaceutical preparations, and as the main bonding component in solid glue products. It has good coating properties and strong initial adhesion, and is suitable for various papers.
Good dispersibility: In pharmaceutical preparations, it can be used as a dispersant for liquid preparations; in the field of coatings, it can be used as a dispersant for water-based coatings.
Good pore-forming agents: PVP K85 and China povidone K90 are excellent pore-forming agents, widely used in water treatment membranes and kidney dialysis membranes.
Good thickener and stabilizer: In the cosmetics field, PVP mainly stabilizes (colloid protection) and thickens dispersed systems such as emulsions and suspensions. It can also be used as a pigment stabilizer in cosmetic formulas.
Pharma use
As a pharmaceutical excipient, povidone can be used as a binder, solubilizer and dispersant for pharmaceutical tablets; a coprecipitant for water-insoluble drugs; a film-forming agent in drug film coating; a drug delay agent and sustained release agent; and an adjuvant for eye drops. PVP povidone K85 can also be used as a material for kidney dialysis membranes.
Industrial use
Povidone can be used as a surface coating agent for organic azo pigments; a dispersant for water-based coatings; detergents containing povidone can not only prevent color transfer or white ground staining during the cleaning process, but also provide cleaning capabilities.
Povidone like povidone K90 also has special adhesion to glass, metal and plastic surfaces. At the same time, povidone can also be used in conductive pastes, photovoltaic cells and solar cells to add povidone to stabilize photo-oxidized/reduced dyes.
Cosmetics use
Povidone has multiple functions in cosmetics, mainly the stabilization (colloid protection) and viscosity-increasing effect on dispersions such as emulsions and suspensions, the film-forming effect of PVP chemical in hair products, the gelling effect in gel products, the lubrication, moisturizing and film-forming effects in skin care products (facial masks), the foam stabilizing effect in foam products, and as a pigment stabilizer, deodorant, fragrance preservative, mild agent (reducing the irritation of certain components to the skin) in various cosmetic formulas of polyvinylpyrrolidone in cosmetics.
