Product introduction
Polyvinylpyrrolidone K15 (PVP 15) is the lower-viscosity viscosity grade in our PVP series. Compared with high-viscosity grades, PVP K15 is especially suitable when you need:
quick water dissolution
good flow behavior
uniform dispersion
reliable wetting/binding support without excessive viscosity load
PVP Product Range We Support
Isteh Chemical can supply the full PVP series:
K17 / K15 / K25 / K30 / K60 / K90 / K120

Product Highlights
A. High-Efficiency Dissolution & Dispersion
PVP K15 supports rapid dissolution and helps improve system flow during manufacturing—reducing formulation friction in mixing and enabling more consistent processing results.
B. Stable Performance for Formulation Uniformity
Used as a binder, solubilizer, stabilizer, or film-supporting polymer, PVP K15 can help deliver better uniformity across batches and reduce variability risks in downstream steps.
C. Multi-Industry Compatibility
Designed for practical use in:
pharmaceutical dosage forms
cosmetics
industrial formulation systems
where reliable polymer quality and predictable behavior are required.
Applications of PVP K15
A) Pharmaceutical Applications
PVP K15 is commonly used in pharma production for functions such as:
tablet binding / cohesion support
solubilization and wetting support for poorly soluble ingredients
stabilization for sensitive or heat-sensitive formulations
process assistance to improve dissolution behavior and uniformity
B) Cosmetics & Personal Care
PVP K15 can support:
film-forming and coating feel
thickening and stabilization assistance
improved dispersion behavior for cosmetic formulations
C) Industrial Applications
PVP K15 is also used for:
stabilization in dispersions
polymer-assist systems where viscosity control and stable dispersion matter
