Silk amino acid 95%
Crosilk™ Liquid
Odor: bland
Use: Crosilk Liquid is composed principally of the free amino acids occuring in silk and can penetrate the cuticle in both damaged and undamaged hair. It exhibits excellent moisture binding properties improving the softness and handling characteristics of the hair. Silk maintains its prestige through associative connotations of luxury, elegance, smoothness and sheen. Our silk protein derivatives not only satisfy marketing label claims, but offer excellent functional performance benefits to meet the demands of today's hair care products.
Odor: characteristic
Use: This natural component of silk has been developed to help nurture hair and skin with silken beauty. Silk extract made from the proteins found in the silk from silkworms provides luster for hair as well as protection for both hair and skin and has long been one of our best-selling products worldwide.

Extrapone® Silk GW N
Odor: characteristic
Use: Extrapone® Silk GW N contains a hydrolysat of silk protein prepared in water and glycerin. Silk caterpillars are mainly cultivated in special breeding farms in China.

The hydrolysat is prepared in a mixture of water, glycerin and preservatives and clear filtrated after an individual ripening time. 1 kg Extrapone® Silk GW N contains approx. 5.75 g silk protein.
