Povidone or Polyvinylpyrrolidone SDS of Manufacturers
CAS Number: 9003-39-8, Molecular Weight: Varies, Chemical Formula: (C6H9NO)n, EINECS EC Number: 294-352-4, FEMA: ----,
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.

Povidone USP Grade
2-Pyrrolidinone, 1-ethenyl-, homopolymer.
1-Vinyl-2-pyrrolidinone polymer [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.
