Molecular Weight (Molecular Weight): 364.95
CAS No:. 25655-41-8
Quality Index (Specification)
Appearance (Appearance): reddish brown or yellow-brown amorphous powder
Content (Purity): a variety of molecular weights
Physical and chemical properties (Physical Properties)
Solubility: PVP is a water-soluble polymer, both miscible with water and can dissolve many alcohols, carboxylic acids, amines, halogenated hydrocarbons and other organic solvents.
Film forming: PVP having very good film-forming properties, PVP was dissolved in certain solvents such as water, methanol, ethanol and the like may be cast or coated film.
Water absorption: PVP with a strong water absorption and moisture retention, commonly used in advanced cosmetics.
Increase in dispersibility and solubility: PVP small molecules have a good dispersion, to prevent mutual aggregation of particles and precipitation. PVP can increase the number of substances
Solubility in aqueous solution.
Complexation: O atoms in the molecule PVP, N atoms are typical ligand atom, it has the ability to complex with some substances, such as iodine, benzene
Class A morpholino and a variety of sulfa drugs.
Effective Iodine 9.0 – 12.0%, an iodine ion% max: 6.6, Heavy metals ppm max: 20, Ash% max: 0.1, nitrogen content% :9.5-11 .5, pH value (10% solution) 1.5 to 5.0 Loss on drying % max: 8.0.
Use (Useage)
Cosmetic
PVP excellent surface activity, film, no skin irritation, no allergic reactions and other characteristics of household chemicals, especially in cosmetics,
Application of skin care products, hair care products and cleaning supplies, etc. has broad prospects. If added with PVP of hairspray and mousse persistent stereotypes,
Has good gloss, and because of PVP with some absorbent, smooth and moisturize the hair will not look boring. Plus a PVP
Skin care products, not only a good moisturizing effect, and in the film formed on the surface of the skin to make the skin with the outside world (such as sunlight) separated, played Paul
Protect the skin.
Medicine
PVP good solubility, Increase soluble, physiologically compatible, bonding capacity and complexing ability of other properties, in the field of medicine and medical health,
Is widely used, can be used as binders, excipients, coating agents, disintegrants, solubilizers, disinfectant, solubilizers, release agent,
Capsule shell, a dispersion stabilizer, film and the like.
Industrial Applications
Adhesives: PVP has a very good solution viscosity, solid glue stick, stamp, band-aid, plaster bandages used as adhesives.
Paints and inks: PVP having excellent dispersibility, the PVP added to the coating to increase the viscosity, improve the coloring power, eliminating
Floating color phenomenon, pigment dispersion and stabilization of the composition, improved gloss, avoid flocculation of the pigment.
The new membrane materials: PVP not only can improve the hydrophilicity of the film, but also by selecting different molecular weight and the amount of PVP
Control, to control the pore size and distribution. Also PVP in drag reduction materials, glass fiber, laser disc, light curing resin, photosensitive materials have applications in areas such as new materials.
