Povidone or Polyvinylpyrrolidone BP Ph Eur Grade Manufacturers
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer. PVP is also used in many technical applications. PVP is also used in personal care products, such as shampoos and toothpastes, in paints, and adhesives that must be moistened, such as old-style postage stamps and envelopes. PVP is the basis of the early formulas for hair sprays and hair gels, and still continues to be a component of some.
As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202. It is also used in the wine industry as a fining agent for white wine or some beers.

Action and use: Disinfectant.
DEFINITION
a-Hydro-w-hydropoly[1-(2-oxopyrrolidin-1-yl)ethylene]. It consists of linear polymers of 1-ethenylpyrrolidin-2-one.
Content: 11.5 per cent to 12.8 per cent of nitrogen (N; Ar 14.01) (anhydrous substance). The different types of povidone are characterised by their viscosity in solution expressed as a K-value.
CHARACTERS
Appearance: White or yellowish-white, hygroscopic powder or flakes.
Solubility: Freely soluble in water, in ethanol (96 per cent) and in methanol, very slightly soluble in acetone.
IDENTIFICATION
First identificationiA, E.
Second identificationiB, C, D, E.
A. Infrared absorption spectrophotometry
B. To 0.4 ml of solution S1 (see Tests) add 10 ml of water, 5 ml of dilute hydrochloric acid and 2 ml of potassium dichromate solution. An orange-yellow precipitate is formed.
C. To 1 ml of solution S1 add 0.2 ml of dimethylaminobenzaldehyde solution and 0.1 ml of sulphuric acid. A pink colour is produced.
D. To 0.1 ml of solution S1 add 5 ml of water and 0.2 ml of 0.05 M iodine. A red colour is produced.
E. To 0.5 g add 10 ml of water and shake. The substance dissolves.
TESTS
Solution S: Dissolve 1.0 g in carbon dioxide-free water and dilute to 20 ml with the same solvent. Add the substance to be examined to the water in small portions, stirring using a magnetic stirrer.
Solution S1: Dissolve 2.5 g in carbon dioxide-free water and dilute to 25 ml with the same solvent. Add the substance to be examined to the water in small portions, stirring using a magnetic stirrer.
Appearance of solution: Solution S is clear and not more intensely coloured than reference solution.
pH: 3.0 to 5.0 for solution S, for povidone having a stated K-value of not more than 30; 4.0 to 7.0 for solution S, for povidone having a stated K-value of more than 30.
Viscosity, expressed as K-value: To pass the test.
The K-value of povidone having a stated K-value of 15 or less is 85.0 per cent to 115.0 per cent of the stated value. The K-value of povidone having a stated K-value or a stated K-value range with an average of more than 15 is 90.0 per cent to 108.0 per cent of the stated value or of the average of the stated range.
Aldehydes: Maximum 5.0×100 ppm, expressed as acetaldehyde.
Peroxides: Maximum 400 ppm, expressed as H2O2.
Formic acid: To pass the liquid chromatography test.
Hydrazine: To pass the test.
Impurity A. R = CH=CH2: 1-ethenylpyrrolidin-2-one (1-vinylpyrrolidin-2-one): To pass the test.
Impurity B. R = H: pyrrolidin-2-one (2-pyrrolidone): To pass the test.
Heavy metals: Maximum 10 ppm.
Water: Maximum 5.0 per cent, determined on 0.500 g.
Sulphated ash: Maximum 0.1 per cent, determined on 1.0 g.
