Promois WK-F is a hydrolyzed keratin of low molecular weight. 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. This product is paraben free. Promois series is peptide, obtained through the hydrolysis of natural proteins, and their derivatives.
Promois WK-F是一种低分子量的水解角蛋白。角蛋白是组成角质层，头发和指甲的结构蛋白之一。它包含80％的人发。就其氨基酸组成而言，它具有胱氨酸，这在任何其他种类的蛋白质中都很少见到。与二硫键相结合，它具有非常独特的分子结构，因此该肽具有良好的交联性。由于这种结构，在单个分子内存在许多官能端基，例如氨基和羧基。因此，角蛋白可以实现高吸附。本产品不含苯甲酸酯。 Promois系列是通过天然蛋白质水解获得的肽及其衍生物。
