Promois WK-HCAQ


SEIWA KASEI Co., Ltd. makes their documentation available in the regions indicated below:

Promois WK-HCAQ is a cationized derivative type of hydrolyzed keratin. It can adsorb to the damaged hair effectively and provide anti-static character because of its cationic character. Keratin is one of the structural proteins composing the stratum corneum, hair, and nails. It comprises 80% of human hair. In terms of its amino acid composition, it has cystine, which is rarely seen in any other kinds of protein. In association with disulfide bond, it has a very unique molecular structure, so the peptide is well cross-linked. Because of this structure, many functional end groups such as amino groups and carboxyl groups exist within a single molecule. Consequently, high adsorption can be achieved with keratin. Promois series is peptide, obtained through the hydrolysis of natural proteins, and their derivatives.
