PVP K-120

PVP K 120
PVP K-120 is soluble in water and many organic solvents and it forms hard, transparent, glossy film. It has an average molecular weight of 3,000,000 in Daltons. PVP 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.
Appearance: White to yellowish-white powder or flakes
Applications:
Ideal for gels, mousses, styling creams/lotions, hair colorants, pomades, waxes, pastes.
While PVP is used as a film former in hair styling products, it can also be used as an emulsion stabilizer in creams and lotions and as a dispersant for hair colorants.

PVP K 120:
PVP (Polyvinylpyrrolidone) K-120 polymer is a hygroscopic, amorphous polymer. It is a linear nonionic polymer that is soluble in water and organic solvents and is pH stable. It forms hard glossy transparent films and have adhesive and cohesive properties.
PVP K-120 Solution is a hygroscopic, amorphous polymer supplied as a clear aqueous solution. It can be plasticized with water and most common organic plasticizers. It is considered to be physiologically inert. This product is cross-linkable to a water insoluble, swellable material either in the course of vinylpyrrolidone polymerization, by addition of an appropriate multifunctional comonomer or by post-reaction, typically through hydrogen abstraction chemistry. PVP products are recommended for dishwashing, fabric care, household cleaning, and industrial and institutional cleaning applications.
PVP K-120 acts as a film former and stabilizer. It is a hygroscopic and amorphous polyvinylpyrrolidone polymer. It stabilizes foam, emulsions, dispersions and suspensions. It offers a range of viscosities that are supplied as either powders or aqueous solutions. It forms clear, hard, shiny and glossy films. It provides strong & stiff hold and excellent compatibility with acrylate thickeners. PVP K-120 finds application in formulating hair care products like mousses, gels, styling lotions/creams, colorants and novelty stylers.
PVP products are linear, non-ionic polymers that are soluble in water and many organic solvents. They are pH stable, and have adhesive, cohesive and binding properties. The unique ability to adsorb on a host of active ingredients makes PVP homopolymers preferred co-dispersants in many formulations. PVP homopolymers have a high glass transition temperature. Lower molecular weight (Mw) PVP polymers (PVP K15 and PVP K30) are suitable for applications where dusting is a concern, such as seed coatings and agglomeration. Higher Mw PVP polymers (PVP K90 and PVP K120) can build formulation viscosity faster and provide excellent binding and film forming properties. Higher Mw PVP polymers are also excellent carriers for pheromones and other attractants.

Key Attributes:
•    Polyvinylpyrrolidone (PVP) can be plasticized with water and most common organic plasticizers. It is considered to be physiologically inert. Applications take advantage of one or more properties inherent in the polymer, typically due to the pyrrolidone ring.
•    High polarity and the resultant propensity to form complexes with hydrogen donors, such as phenols and carboxylic acids, as well as anionic dyes and inorganic salts.
•    Dispersancy, where components in a mixture are uniformly distributed through the use of polyvinylpyrrolidone. Hydrophilicity, where the water solubility of PVP is its dominant feature and frequently a factor along with other properties valuable in numerous applications.
•    Adhesion, taking advantage of the higher molecular weight PVP formulating in aqueous media, then evaporating sufficient water to generate a solid product for the desired application.
•    Cohesivity, where cohesive strength is achieved through a variety of dry blending and granulation techniques.

Applications and Usage Notes:
•    Adhesives – pressure-sensitive and water-remoistenable types, food packaging (indirect food contact), metal adhesives, abrasives, sandcore binder, rubber to metal adhesives and glue sticks.
•    Ceramics – binder in high temperature fire-prepared products such as clay, pottery, porcelain, brick product, dispersant for ceramic media slurries and viscosity modifier.
•    Electronic Applications – storage batteries, printed circuits, cathode ray tubes, binder for metal salts or amalgams in batteries, gold, nickel, copper and zinc plating, a thickener for solar gel ponds and as an adhesive to prevent leakage of batteries, serves as an expander in cadmium-type electrodes, binder in sintered-nickel powder plates.
•    Membranes – macroporous, multiporous, desalination, gas separating, liquid ultrafiltration, hemodialysis, selective permeability types of membranes, hollow fiber membranes.
•    Metallurgy – processing for both ferrous and non ferrous metals, coating ingredient to aid or remove material from metal surfaces such as copper, nickel, zinc and aluminum, used in metal quenchant bath.

PVP K120 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. (However, autopsies have found that crospovidone (PVPP) contributes to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption. The long-term effects of crospovidone or povidone within the lung are unknown).
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.
Toxicology, and safety:
After the introduction of PVP in polymer science, extensive research has been done in developing its pharmacokinetic and toxicological profile. Different animal models and humans have been tested to study the kinetic profiling of PVP. Since PVP is proposed for different fields of interest, particularly the medical, pharmaceutical, and food industry, its safety profiling became a necessity and hence detailed information has been documented in the literature. Both the individual researchers and regulatory bodies have concluded that PVP usage is safe as both a food-grade additive and also as a pharmaceutical excipient. WHO has given a listing of its acceptable daily intake of 0–50 mg/kg body weight.
A good number of reports claim that PVP is biologically inert and non-toxic with good tolerance. A huge data concerning toxicological studies in animals like rats, pigs, dogs, and rabbits revealed that orally administered PVP shows no acute or subchronic or chronic toxicity. In some cases, an extremely low effect like diarrhea is observed at high doses. The reason is the osmotic action shown by PVP at high doses which acts as a bulk purgative. There is no evidence of toxicity in terms of clinical chemistry, histopathology, and hematology except diarrhea at high doses. As per the reports, the LD50 value for oral administration of PVP (average molecular weight 40,000) is greater than 100 g/kg body weight in both rats and guinea pigs. Hence, PVP is claimed as neither a sensitizer nor an irritant. Even in humans, there are no reported adverse effects with oral administration of PVP.
