PVP-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
