Molecular Weight: Varies
PVP K-30 and PVP K90 Povidone or Polyvinylpyrrolidone
(C6H9NO)*x
2-Pyrrolidinone, 1-ethenyl-, homopolymer.
1-Vinyl-2-pyrrolidinone polymer CAS 9003-39-8
Povidone is a synthetic polymer consisting essentially of linear 1-vinyl-2-pyrrolidinone groups, the degree of polymerization of which results in polymers of various molecular weights. The different types of Povidone are characterized by their viscosity in aqueous solution, relative to that of water, expressed as a Kvalue. The K-value of Povidone having a stated (nominal) K-value of 15 or less is not less than 85.0 percent and not more than 115.0 percent of the stated values. The K-value of Povidone having a stated K-value or a stated K-value range with an average of more than 15 is not less than 90.0 percent and not more than 108.0 percent of the stated value or of the average of the stated range.
Labeling: Label it to state, as part of the official title, the K-value or K-value range of the Povidone.
Identification:
A: To 10 mL of a solution (1 in 50) add 20 mL of 1 N hydrochloric acid and 5 mL of potassium dichromate an orange-yellow precipitate is formed.
B: Dissolve 75 mg of cobalt nitrate and 300 mg of ammonium thiocyanate in 2 mL of water. To this solution add 5 mL of a solution of Povidone (1 in 50), and render the resulting solution acid by the addition of 3 N hydrochloric acid: a pale blue precipitate is formed.
C: To 5 mL of a solution (1 in 200) add a few drops of iodine: a deep red color is produced.
pH: between 3.0 and 7.0, in a solution (1 in 20).
Water: not more than 5.0%.
Residue on ignition: not more than 0.1%.
Lead: Dissolve 1.0 g in 25 mL of water: the limit is 10 ppm.
Limit of aldehydes: not more than 0.05% is found.
Limit of hydrazine: To pass the test.
Vinylpyrrolidinone: To pass the test.
K-value: To pass the test.
Nitrogen content: The nitrogen content, on the anhydrous basis, is not less than 11.5% and not more than 12.8%.
Polyvinylpyrrolidone FCC Food Grade Specifications
PVP; Povidone; Poly[1-(2-oxo-1-pyrrolidinyl)ethylene]
(C6H9NO)x

Higher mol wt range product ~360,000
INS: 1201 CAS 9003-39-8
DESCRIPTION
Polyvinylpyrrolidone occurs as a white to tan powder. It is a polymer of purified 1-vinyl-2-pyrrolidone produced catalytically. It is soluble in water, in alcohol, and in chloroform, and is insoluble in ether. The pH of a 1:20 aqueous solution is between 3 and 7.
Function: Clarifying agent; separation/filtration aid; stabilizer; bodying agent; tableting aid; dispersant; coating on fresh fruit.
REQUIREMENTS
Labeling: Indicate the K-value or the K-value range.
Identification:
A. Add 20 mL of 1 N hydrochloric acid and 5 mL of potassium dichromate TS to 10 mL of a 1:50 aqueous solution. An orange-yellow precipitate forms.
B. Add 5 mL of a 1:50 aqueous solution to 75 mg of cobalt nitrate and 300 mg of ammonium thiocyanate dissolved in 2 mL of water, mix, and then make the resulting solution acid with 2.7 N hydrochloric acid. A pale blue precipitate forms.
C. Add a few drops of iodine TS to 5 mL of a 1:200 aqueous solution. A deep red color appears.
Assay: Not less than 11.5% and not more than 12.8% as nitrogen (N), calculated on the anhydrous basis.
Aldehydes: (as acetaldehyde) Not more than 0.05%.
Hydrazine: Not more than 1 mg/kg.
K-Value: Between 27 and 32 for the lower-molecularweight-range product, and between 81 and 97 for the highermolecular-weight-range product.
Lead: Not more than 2 mg/kg.
Residue on Ignition: Not more than 0.1%.
Unsaturation: (as vinylpyrrolidone) Not more than 0.1%.
Water: Not more than 5.0%.
