Product Description
Copovidone VA64 Product Introduction:
Polyvinylpyrrolidone (PVP), additionally referred to as polyvidone or povidone, is a polymer compound developed by the polymerization of N-vinyl-2-pyrrolidone.
Different proportion of Vinylpyrrolidone to vinylacetate can be offered in powder, alcohol solution and aqueous solution products.The aqueous solution product may be varied from transparent to cloudy. The clarity of the solution depends on the proportion of Vinylpyrrolidone to vinylacetate. The solution is slight acidic but not electrolytic.
Polyvinylpyrrolidone (PVP)/Copovidone Uses:
- Polyvinylpyrrolidone (PVP) is the main raw material of cosmetics, used in hair spray, shampoo, and so on. It is also utilized in surfactant, pharmaceutical as well as various other sectors.
- Copovidone is primarily utilized in granulation and also straight compression innovation as a water-soluble binder and a dry binder, as a film-forming product in movie layer, and as a pore previous in preference masking representatives. Apply topping to prevent splitting and base coat to stop wetness.
- Copovidone is used as a binder for preparations.
- Because of its low toxicity, it is soluble in water and most organic solvents, so it can be used as food clarifying agent and stabilizer, as well as styling agent, dispersant and affinity agent for personal care products; Polyvinylpyrrolidone is also used as an excipient for pharmaceutical preparations.
- Polyvinylpyrrolidone is additionally made use of as an excipient for pharmaceutical prep work.
