PROPERTIES

Sunlydone K products are mainly used as film formers, but also as thickeners, dispersing and stabilizing agents. The molecular weight determines 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

l Water-soluble in high concentrations to form clear solutions

l Form clear, homogeneous films

At low relative humidity the films are hard and brittle; at high relative humidity they are elastic and soft

l High water-absorption capacity

l Mixtures with polyacrylates, polyquats, salts, acids and bases are possible; high compatibility with many other cosmetic ingredients

l Nonionic, no neutralization required

APPLICATIONS

l Hair gels, in particular wetlook gels, hair mousses, pump sprays, liquid hair setting preparations.

l Film former in hair styling products. Emulsion stabilizer. De-stainer and gelling agent in toothpastes.

l Sunlydone K30 for products with normal hold, for which low viscosity is important (e.g. pump sprays)

l Sunlydone K90 for products with a strong hold and high viscosity (e.g. hair gels and hair mousses)

Typical use level for PVP K30 is 3-6%; K90 is 1-3%; typical PH range is 3-7.5
