PVP K-30 and PVP K90

PVP K-30 and PVP K90 powder is soluble in water and many organic solvents and it forms hard, transparent, glossy film.
PVP K-30 and PVP K90 is compatible with most inorganic salts and many resins. PVP stabilizes emulsions, dispersions and suspensions. While PVP is used as a film former in hair styling products, PVP can also be used as an emulsion stabilizer in creams and lotions and as a dispersant for hair colorants. Additionally, pharmaceutical grade PVP can be used in toothpastes and mouthwashes. It is used in several industries like adhesives, ceramics, glass and glass-fiber, inks and coatings, electronic appliances, lithography and photography, fibers and textiles, membranes, metallurgy, paper, etc.

PVP K30 can be offered as powder or 70% water-solution or as required by the buyer.
PVP K90 can be offered as powder or 10% 15% 20% water solution or as required by the buyer.

DESCRIPTION
PVPK 30 or PVP K90 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: PVP K30 between 27 and 32 for the lower-molecularweight-range product, (and between 81 and 97 for the higher molecular-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%.
