In an era where precision and safety matter across pharmaceuticals, cosmetics, and industrial manufacturing,
PVP K15 (Polyvinylpyrrolidone K15) emerges as a standout low-molecular-weight water-soluble polymer.
Developed by Dalian Sinobio Chemistry Co., Ltd.—a 18-year leader in fine chemicals—it blends innovation with practicality to meet diverse industry needs.
PVP K15 is a white free-flowing powder with a molecular weight of 8,000–15,000 (K-value 12–17). Key properties include excellent solubility (dissolves fully in water and organic solvents like ethanol), stability across pH 3–7, high biocompatibility (compliant with USP), and low viscosity—ideal for fluid formulations. Its functionality stems from its structure: polar amide groups form complexes with drugs/pigments to boost stability, while it forms thin, flexible films for coatings or hair styling. As a dispersant, it prevents particle agglomeration in suspensions.
1. In exploration & drilling, it serves as a drilling fluid additive: its polar amide groups inhibit clay swelling/dispersion to stabilize wellbores, reduce fluid filtration to protect oil reservoirs, and its low viscosity ensures fluidity for varied geological conditions.
2. In crude oil extraction, it functions as an oil displacement aid (lowers oil-water tension to boost recovery) and wax inhibitor (prevents wax deposition on pipes, reducing blockages and maintenance costs).
3. In refining, it refines lubricating oils (as a dispersant to prevent impurity aggregation, extending oil life) and fuel oils (binds polar impurities to improve stability and combustion efficiency, cutting emissions).
1. Oral formulations (syrups, suspensions): Improves solubility and stability of poorly soluble drugs; acts as a taste-masking agent.
2. Tablet & capsule manufacturing: Serves as a binder (enhances tablet hardness) or a film-coating base (protects active ingredients from moisture).
3. Topical preparations (creams, sprays): Enhances ingredient dispersion and reduces skin irritation.
1. Hair care (mousses, sprays): Forms a flexible, water-soluble film for long-lasting styling; adds shine without residue.
2. Skin care (serums, lotions): Improves the spreadability of active ingredients (e.g., vitamins, hyaluronic acid) and boosts formulation stability.
3. Oral care (mouthwashes, toothpastes): Enhances the solubility of antibacterial agents and freshens breath.
