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
