Promois SILK-1000Q is a cationized derivative type of hydrolyzed silk protein. It can adsorb to the damaged hair effectively and provide anti-static character because of its cationic character. Silk protein is formed by a piece of fiber consists of fibroin, which is fibrous protein, and amorphous protein of sericin. Fibroin has a unique amino acid composition. It is rich in glycine, alanine and serine which have small molecular weight and simple chemical structure, comprises 90% of the total. The composition is known to form a sheet structure. Consequently, the comfortable touch associated with Silk can be generated. Furthermore, moisturizing effect is expectable because of its original amino acid composition. Promois series is peptide, obtained through the hydrolysis of natural proteins, and their derivatives.

Promois SILK-1000Q是一种阳离子衍生型水解丝蛋白。由于其阳离子特性，它可以有效地吸附受损头发并提供抗静电特性。蚕丝蛋白是由纤维蛋白组成的一片纤维形成的，纤维蛋白是纤维蛋白，和丝胶蛋白的无定形蛋白。丝心蛋白具有独特的氨基酸组成。它含有丰富的甘氨酸，丙氨酸和丝氨酸，分子量小，化学结构简单，占总量的90％。已知该组合物形成片材结构。因此，可以生成与丝绸相关的舒适触感。此外，由于其原始的氨基酸组成，可以期待保湿效果。 Promois系列是肽，通过天然蛋白质的水解获得，和他们的衍生物。
