DOCUMENTS
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer made from the monomer N-vinylpyrrolidone
Medical
PVP was used as a plasma volume expander for trauma victims after the 1950s.
It is not preferred as volume expander due to its ability to provoke histamine release and also interfere with blood grouping.
It is used as a binder in many pharmaceutical tablets;it simply passes through the body when taken orally.
PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties.
This complex is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs.
It is known under the trade names Pyodine and Betadine, among a plethora of others.
It is used in pleurodesis (fusion of the pleura because of incessant pleural effusions).
For this purpose, povidone iodine is equally effective and safe as talc, and may be preferred because of easy availability and low cost.
PVP is used in some contact lenses and their packaging solutions.
It reduces friction, thus acting as a lubricant, or wetting agent, built into the lens.
Examples of this use include Bausch & Lomb’s Ultra contact lenses with MoistureSeal Technology and Air Optix contact lens packaging solution (as an ingredient called “copolymer 845”).
PVP is used as a lubricant in some eye drops, e.g. Bausch & Lomb’s Soothe.
Technical
PVP is also used in many technical applications:
as an adhesive in glue stick and hot-melt adhesives
as a special additive for batteries, ceramics, fiberglass, inks, and inkjet paper, and in the chemical-mechanical planarization process

as an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms (syrups, soft gelatine capsules) and as an inhibitor of recrystallisation
as an additive to Doro’s RNA extraction buffer
as a liquid-phase dispersion enhancing agent in DOSY NMR
as a surfactant, reducing agent, shape controlling agent and dispersant in nanoparticle synthesis and their self-assembly
as a stabilizing agent in all inorganic solar cells
Other uses
PVP binds to polar molecules exceptionally well, owing to its polarity.
This has led to its application in coatings for photo-quality ink-jet papers and transparencies, as well as in inks for inkjet printers.
PVP K 90 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.
It has also been used in contact lens solutions and in steel-quenching solutions.
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 and some beers.
In molecular biology, PVP can be used as a blocking agent during Southern blot analysis as a component of Denhardt’s buffer.
It is also exceptionally good at absorbing polyphenols during DNA purification.
Polyphenols are common in many plant tissues and can deactivate proteins if not removed and therefore inhibit many downstream reactions like PCR.
In microscopy, PVP is useful for making an aqueous mounting medium.
PVP can be used to screen for phenolic properties, as referenced in a 2000 study on the effect of plant extracts on insulin production.

Safety
The U.S. Food and Drug Administration (FDA) has approved this chemical for many uses, and it is generally considered safe.
However, there have been documented cases of allergic reactions to PVP/povidone, particularly regarding subcutaneous (applied under the skin) use and situations where the PVP has come in contact with autologous serum (internal blood fluids) and mucous membranes.
For example, a boy having an anaphylactic response after application of PVP-Iodine for treatment of impetigo was found to be allergic to the PVP component of the solution.
A woman, who had previously experienced urticaria (hives) from various hair products, later found to contain PVP, had an anaphylactic response after povidone-iodine solution was applied internally.
She was found to be allergic to PVP.
In another case, a man experiencing anaphylaxis after taking acetaminophen tablets orally was found to be allergic to PVP.
Povidone is commonly used in conjunction with other chemicals.
Some of these, such as iodine, are blamed for allergic responses, although testing results in some patients show no signs of allergy to the suspect chemical.
Allergies attributed to these other chemicals may possibly be caused by the PVP instead.

PVP polymers are available in several viscosity grades, ranging from low to high molecular weight. This range, coupled with solubility in aqueous and organic solvent systems combined with its nontoxic character, are some of the properties that gives PVP polymers great flexibility across multiple applications. The industrial applications of PVP polymers include, for example, in adhesives to improve strength and toughness; in paper manufacture to increase strength and as a coating resin; and in synthetic fibers to improve dye receptivity. PVP polymers are also widely employed in inks, imaging, lithography, detergents and soaps, the textile, ceramic, electrical and metallurgical industries and as a polymerization additive.
There have been many studies that have been devoted to the determination of the molecular weight of PVP polymer. The low molecular weight polymers have narrower distribution curves of molecular entities than the high molecular weight compounds. Some of the techniques for measuring the molecular weight of various PVP polymer products are based on measuring sedimentation, light scattering, osmometry, NMR spectroscopy, ebullimometry, and size exclusion chromatography for determining absolute molecular weight distribution. By the use of these methods, any one of three molecular weight parameters can be measured, namely the number average (Mn), viscosity average (Mv), and weight average (Mw). Each of these characteristics can yield a different answer for the same polymer as illustrated by using these measurement techniques in the analysis of the same PVP K-30 polymer sample. The following results are reported: Number average (Mn) – 10,000 Viscosity average (Mv) – 40,000 Weight average (Mw) – 55,000 Therefore, in any review of the literature, one must know which molecular average is cited. Conventionally, molecular weights are expressed by their “K-values,” which are derived from relative viscosity measurements.
Small amounts of PVP polymer effectively stabilize emulsions, dispersions, and suspensions. Even lyophobic colloids, which exist without significant affinity for the medium, can be protected by PVP polymer. The polymer is adsorbed in a thin molecular layer on the surface of the individual colloidal particles to prevent contact and overcome any tendency to form a continuous solid phase. The best viscosity grade to use depends on the application. In some cases, the lower molecular weight polymers, PVP K-15 polymer or PVP K-30 polymer, are more efficient than high molecular weight material. For example, PVP K-15 polymer is particularly effective as a dispersant for carbon black and lowbulk density solids in aqueous media. It is used in detergent formulations to prevent soil redeposition on synthetic fibers and as a protective colloid for certain pigments. In viscous systems, on the other hand, PVP K-90 polymer is most suitable, e.g., as a dispersant for titanium dioxide or organic pigments and latex polymers in emulsion paints. PVP K-90 polymer is preferred as the protective colloid in the suspension polymerization of styrene to generate the desired particle size.
Complex Formation/Crosslinking PVP polymers form molecular adducts with many other substances. This can result in a solubilizing action in some cases or in precipitation in others. PVP polymer crosslinks with polyacids like polyacrylic or tannic acid to form complexes which are insoluble in water or alcohol but dissolve in dilute alkali. Gantrez™ AN methyl vinyl ether/maleic anhydride copolymer, will also insolubilize PVP polymer when aqueous solutions of polymers are mixed in approximately equal parts at low pH. An increase in pH will solubilize the complex. Ammonium persulfate will gel PVP polymer in 30 minutes at about 90°C. These gels are not thermoreversible and are substantially insoluble in large amounts of water or salt solution.
PVP polymer powder can be stored under ordinary conditions without undergoing decomposition or degradation. However, since the powder is hygroscopic, suitable precautions should be taken to prevent excessive moisture pickup. Bulk polymer is supplied in tied polyethylene bags enclosed in fiber packs. When not in use, the polyethylene bag should be kept closed at all times in the covered container. On PVP polymer films, moisture acts as a plasticizer. These films are otherwise chemically stable. The equilibrium water content of PVP polymer solid or films varies in a linear fashion with relative humidity and is equal to approximately one-third the relative humidity. Samples of dried, powdered PVP polymer, subjected to 20, 52, and 80 percent relative humidity until equilibrium is reached, show a 10, 19, and 31 percent moisture weight gain, respectively. Exposure to extreme elevated temperatures should be avoided, though PVP polymer powder is quite stable when heated. Some darkening in color and decreased water solubility are evident on heating in air at 150°C. However, PVP polymer appears to be quite stable when heated repeatedly at 110-130°C for relatively short intervals. Aqueous PVP polymer is stable for extended periods if protected from molds. However, appropriate tests should be made with finished products containing PVP polymer before deciding on a preservative. Steam sterilization (15 lb. pressure for 15 min.) can also be used and this treatment does not appear to change the properties of the solutions. The PVP polymer has no buffering power, and substantial changes in the pH of solutions are observed upon addition of small amounts of acids or bases. For example, the pH of 100 ml of 3.5% PVP K-30 polymer solution is raised from pH 4 to pH 7 by the addition of 1-2 ml 0.1 N sodium hydroxide.
Polyvinylpyrrolidone is widely used in a broad variety of industries. This is due to its unique physical and chemical properties, particularly because of its good solubility in both water and many organic solvents, its chemical stability, its affinity to complex both hydrophobic and hydrophilic substances and its nontoxic character. Several hundreds of papers have been published describing the advantages of using PVP polymer in formulas for the following product areas
Adhesives – pressure-sensitive and water-remoistenable types, food packaging (indirect food contact), metal adhesives, abrasives, sandcore binder, rubber to metal adhesives and glue sticks. Specific adhesive for glass, metal, plastics. Imparts high initial tack, strength, hardness. Particularly suitable for remoistenable adhesive applications. Forms grease-resistant films. Films can be cast from water or organic solvents. Modifies viscosity of polymer-based adhesives. Raises cold-flow temperature. Raises softening point of thermoplastics
Ceramics – binder in high temperature fire-prepared products such as clay, pottery, porcelain, brick product, dispersant for ceramic media slurries and viscosity modifier.
