High Quality PVP/povidona solution/liquid

Specifications

CAS No.: 9003-39-8

Grade Standard: Medicine Grade

Brand Name:Sunvidone

Appearance: clear yellowish liquid, soluble in water

Storage: kept in a light-proof,well-colsed,dry and cool place

Solubility and miscibility

Polyvinylpyrrolidone is a polymer with different molecular weight of ethylene pyrrolidone. It is easily soluble in water and will not be electrolyzed. Its aqueous solution can be miscible with the solution of cellulose series. It can also be mixed with non-ionic, anionic or cationic components such as salicylic acid. Sunlydone K series products could make the settlement by adding a lot of salt, including K90 easier than K17 settlement. PVP in the difference in different solubility in organic solvents, the following table contains a series of organic solvents. Sunlydone K series dissolved in the solvent contains at least 10% PVP solution can be obtained.

storage stability

The viscosity of aqueous solution increases when the PH value is higher than 6 and it is stored at higher temperatures. Acidified solutions (concentrations less than 30%) have a tendency to clack when stored and can be prevented by the addition of stabilizers. OH or NH2 stabilizers are not recommended.
