Povidone Powder

PVP K Series As Tablet/Pill Binder

Polyvinylpyrrolidone, or PVP, known as Povidone in the medical domain, is a non-ionic water-soluble polymer compound. Among the N-vinyl amide polymers, it stands out as the most distinctive and well-studied variety with a history of 80 years as a commercial product. It has evolved into a family of polymers that includes homopolymers, copolymers, cross-linked polymers, and polymer complexes that fall into three classes: nonionic, cationic, and anionic, and three grades: industrial grade, pharmaceutical grade, and food grade, with molecular weights ranging from several thousand to more than one million, which are widely used in a variety of industries and scientific research departments around the globe for their excellent and unique properties; Annually, more than a thousand publications and patents are issued in this field, demonstrating its growing importance and global reach.

Povidone K Series Pharmaceutical Excipients

Povidone, also known as polyvinylpyrrolidone (PVP) or polyvidone, is a synthetic water-soluble polymer made from the monomer N-vinylpyrrolidone used as a binder in many pharmaceutical tablets and lubricant in eye drops. It is also used in many technical applications with various roles as an adhesive, additive, and emulsifier. When in complex with iodine, Povidone-iodine displays antiseptic properties where the iodine, a bactericidal component, mainly contributes to this effect, and povidone acts as a carrier 1. Povidone-iodine can be found in over-the-counter topical solutions, ointment, pessaries, liquid soaps and surgical scrubs. The clinical effectiveness of Povidone-iodine on wound healing remains somewhat controversial, as it was demonstrated in a few clinical studies that the application of the compound in wounds was associated with impaired wound healing, reduced wound strength, or infection in open wounds.

PVP/Povidone K Series

It is mainly used as water soluble and drying adhesive agent when making grain and pressing tablet directly. It will be used in film coating and cover-taste agent. It can prevent sugar coating from split and make bottom coating avoid dampness. PVP Series play a good role in film-former and hair-fixing agent. Its hygroscopicity decreases with the increase of the proportion of vinylacetate in the molecular. This property of PVP is extremely useful as it works in hair sprays and hair-set lotion. If it is mixed with PVP K-30, the effect of hair-fixing would be changed a lot. PVP series can be used in remoistenable adhesive and other adhesives for paper or viscosity-enchancing agent and protecting colloid for printing ink. PVP series can also act as emulsifying agent, protecting colloid for planting-protecting chemicals, other dispersing systems and binder in coating.

Polyvinylpyrrolidone Cosmetic Grade

It is Homopolymers of vinylpyrrolidone with a variety of molecular weights Supplied as solutions,powders or flakes. It is mainly used as film formers, but also as thickeners, dispersing and stabilizing agents. The molecular weight determines the setting. They are ideal for use in water-based applications where a high degree of clarity is required in the finished product (e.g. Gels). For hair-styling applications K30 and K85 are the best of the various molecular weights.

Polyvinylpyrrolidone/Povidone/PVP

Polyvinylpyrrolidone K Serise are excellent new pharmaceutical excipients. They are mainly used as binder for tablets, pills, granules, cosolvents for injections, glidants for capsules, dispersants for liquid preparations and colorants, enzymes and Heat-sensitive drug stabilizer, insoluble drug co-precipitation agent, ophthalmic detoxification agents and lubricants; use of PVP products for excipients have hundreds of drugs.

Povidone Powder

White or creamy white powder,odourless,nontoxic,non-irritant,dissolves readily in water,alcohol,amine and many other organic solvents.PVP K Series is widely used in pharmaceutical fields,thanks to it's excellent solubility,film-formingcapability, chemical stability,physiologicalinertia and cementability.

Polymer Polyvinylpyrrolidone (PVP) K Series 9003-39-8

Sunlydone K products are mainly used as film formers, but also as thickeners. The molecular weight determines the setting and adhesive properties of PVP polymers; the higher the molecular weight, the greater the setting. They are ideal for use in water-based applications where a high degree of clarity is required in the finished product (e.g. Gels). For hair-styling applications K30 and K85 are the best of the various molecular weights.

PVP/Povidone K

As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, such as colloid protection, film formation, cohesiveness, hygroscopicity, solubilization or condensation, and complexation ability with some compounds. But its most distinctive, and therefore received people's attention is its excellent solubility, complexation and biocompatibility. Among synthetic polymers, PVP is soluble in water and most organic solvents, with low toxicity and good biocompatibility.

PVP K30

PVP K30 is commonly used as binders for the development of tablet formulations, whether manufactured by wet granulation, dry granulation, or direct compression. It is used in solid dispersion formulations to enhance the solubility of active pharmaceutical ingredients and increase bioavailability. It is also used to inhibit recrystallization in liquid soft gels.
