PROPERTIES
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.
EFFICIENCY CLAIMS
• Water-soluble in high concentrations to form clear solutions
• Form clear, homogeneous films
At low relative humidity the films are hard and brittle; at high relative humidity they are elastic and soft
• High water-absorption capacity
• Mixtures with polyacrylates, polyquats, salts, acids and bases are possible; high compatibility with many other cosmetic ingredients
• Nonionic, no neutralization required
APPLICATIONS
• Hair gels, in particular wetlook gels, hair mousses, pump sprays, liquid hair setting preparations.
• Film former in hair styling products. Emulsion stabilizer. De-stainer and gelling agent in toothpastes.
• Sunlydone K30: for products with normal hold, for which low viscosity is important (e.g.pump sprays)
• Sunlydone K90: for products with a strong hold and high viscosity (e.g.hair gels and hir mousses)
Typical use level for PVP K30 is 3-6%; K90 is 1-3%; typical pH range is 3-7.5
