Polyvinylpyrrolidone (PVP),also known as K90 is a water soluble polymer with good bio-stability. It is chemically stable, has low toxicity and is biocompatible. Hence, it is useful in a variety of applications such as cosmetics, tissue engineering, and biomedical engineering.

Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.

Plasdone™ K polymers are used in solid dispersion formulations to enhance the solubility of active pharmaceutical ingredients and increase bioavailability. Plasdone™ K grades are also used to inhibit recrystallization in liquid soft gels. For country-specific details, please contact your local sales representative.

2024年11月18日 · Povidone K90. Medically reviewed by Drugs.com. Last updated on Nov 18, 2024. Excipient (pharmacologically inactive substance) What is it? Povidone (polyvinylpyrrolidone, PVP) is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs.

Polyvinylpyrrolidone is a hygroscopic, amorphous polymer supplied as a white, free-flowing powder or a clear aqueous solution. Available in several molecular weight grades, they are characterized by K-value, and used in a great variety of applications.

2023年7月18日 · PVP K-90 is the larger polymer chain length version of PVP K-30, the only difference between the two. In hair styling K-90 will give a harder hold per gram weight but is less soluble in water and less flexible when plasticized. Think crunchier.

Povidone Poly vinylpyrrolidone PVP K17 K30 K90 are widely applied in a wide range in hair care, skin care & oral care products. Povidone Poly vinylpyrrolidone PVP K17 K30 K90 are particularly suitable for formulations where viscosity modification and film forming properties are needed.

2024年4月29日 · Choosing between PVP K30 and K90 often depends on the desired balance between solubility, viscosity, and film-forming capacity. While PVP K30 is better suited for immediate-release applications, PVP K90 excels in scenarios where durability and extended release are priorities.
