Specification:
The specifications of PVP K90 can vary depending on the specific grade and manufacturer. Here are some general specifications:

• Chemical formula: (C6H9NO)n
• Molecular weight: Typically ranges from 1,000,000 to 1,200,000 g/mol
• Appearance: White or off-white, free-flowing powder
• Purity: Typically, not less than 95% or higher (depending on the grade)
• Solubility: Soluble in water and many organic solvents, such as ethanol and methanol

Application:
PVP K90 finds a wide range of applications in various industries, including:

1. Pharmaceuticals: PVP K90 is commonly used in the pharmaceutical industry as a binder, disintegrant, and film-forming agent in tablet and capsule formulations. It helps to improve the dissolution and bioavailability of active pharmaceutical ingredients. PVP K90 can also be used as a stabilizer in suspensions and emulsions.

2. Cosmetics and personal care products: PVP K90 is utilized in the formulation of cosmetic and personal care products. It is used as a film-forming agent, hair fixative, thickener, and viscosity enhancer in products such as hair sprays, gels, mousses, creams, lotions, and shampoos. PVP K90 provides excellent hold, humidity resistance, and improves the texture of these products.

3. Industrial applications: PVP K90 finds applications in various industrial sectors. It is used as a dispersant, binding agent, and protective colloid in the production of adhesives, coatings, paints, and inks. PVP K90 can also be used as a stabilizer in polymerization processes and as a suspending agent in ceramic and pigment applications.

4. Food and beverages: PVP K90 is approved for use as a food additive by regulatory authorities. It is used as a stabilizer, clarifying agent, and thickener in food and beverage products. PVP K90 can be found in products such as beer, wine, fruit juices, and confectionery.

Features:

1. Water solubility: PVP K90 exhibits excellent solubility in water, which makes it easy to incorporate into aqueous formulations and allows for uniform distribution.

2. Film-forming properties: PVP K90 has film-forming capabilities, forming a transparent and flexible film upon drying or application. This property is valuable in applications where a protective or cosmetic film is desired.

3. Binding and encapsulating properties: PVP K90 acts as a binder, holding together powdered or granulated materials in tablet and capsule formulations. It also has encapsulating properties, helping to improve the stability and controlled release of active ingredients.

4. Compatibility: PVP K90 is compatible with a wide range of active ingredients, excipients, and other polymers, making it versatile for formulation purposes.

Industrial and medical

pvp was used as a plasma volume expander for trauma victims after the 1950s.

it is used as a binder in many pharmaceutical tablets; it simply passes through the body when taken orally. however, autopsies have found thatcrospovidone (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-iodinethat 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 betadine and pyodine 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.

technical

pvp is also used in many technical applications:

• as an adhesive in glue stick and hot-melt adhesives
• as a special additive for membranes, such as dialysis and water purification filters
• as a binder and complexation agent in agro applications such as crop protection, seed treatment and coating
• as a thickening agent in tooth whitening gels
• as an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms (syrups, soft gelatine recrystallisation
• as an additive to doro's rna extraction buffer
• as a liquid-phase dispersion enhancing agent in dosy nmr

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 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 forhair sprays and hair gels, and still continues to be a component of some.

as a food additive, pvp is a fining agent forwhite wine or some beers. other references state that polyvinyl pyrrolidone and its derivatives are fully from mineral synthetic origin. therefore, its use in the production should not be a problem for vegans.

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.
