Product: PVK-30 / Polyvinylpyrrolidone (PVP K-30)
Rchem PVP K-30 is a high-purity, water-soluble synthetic polymer, presented as a fine, white to off-white, free-flowing powder. This versatile, non-ionic polymer is part of the polyvinylpyrrolidone family, with the “K-30” designation indicating an average molecular weight of approximately 40,000-50,000 Daltons. Renowned for its exceptional binding, film-forming, and complexing properties, it is a cornerstone ingredient in pharmaceutical, cosmetic, food, and industrial applications for tablet binding, adhesion enhancement, and stabilization of suspensions.

Frequently Asked Questions:
What does the "K-30" designation mean in PVP?
The "K-Value" is a measurement of the average molecular weight and viscosity of PVP polymers. K-30 indicates an average molecular weight range of approximately 40,000-50,000 Daltons. Lower K-values (e.g., K-12, K-17) represent lower molecular weights and viscosities, while higher K-values (e.g., K-90) represent higher molecular weights, higher viscosities, and stronger film-forming properties. K-30 offers an optimal balance of binding strength and solubility.
The primary difference is molecular weight and viscosity. PVP K-30 has a lower molecular weight (40,000-50,000 Da), resulting in lower solution viscosity and excellent binding properties with faster dissolution. PVP K-90 has a much higher molecular weight (>1,000,000 Da), producing much higher viscosity solutions and stronger, more durable films. K-30 is preferred for tablet binding and low-viscosity applications; K-90 is preferred for thickening and high-strength film applications.
: What is the primary difference between PVP K-30 and PVP K-90?
Yes, this is a highly valued property. PVP K-30 acts as a solid dispersion carrier for poorly soluble drugs. By coprecipitating or spray-drying the drug with PVP, the drug can be maintained in an amorphous, non-crystalline state, which dramatically increases its dissolution rate and, consequently, its bioavailability. This is a standard technique in modern pharmaceutical formulation.
Can PVP K-30 be used to increase the bioavailability of poorly soluble drugs?
Absolutely. PVP K-30 is a classic and preferred ingredient in clear hair styling gels and sprays. It dissolves to form perfectly clear solutions and dries to form a clear, non-flaking, flexible film that provides excellent hold without tackiness or visible residue. It is compatible with most other styling ingredients.
Is PVP K-30 suitable for use in clear hair styling gels?
As a fine powder, it can be dusty. Use appropriate personal protective equipment (PPE) including a dust mask, gloves, and safety goggles. Store in a cool, dry place in tightly sealed containers to prevent moisture absorption. For dissolution, add the powder slowly to water with constant agitation to prevent clumping and "fish-eye" formation. While generally non-toxic, avoid inhalation of dust. Always refer to the Safety Data Sheet (SDS) for comprehensive handling and safety information.
