Promois S-700SIGF is a silylated derivative of hydrolyzed silk protein. It protects and repairs hair, and improves its texture by a heat enhancing effect that results in the formation of a film on the hair in response to heat from hair dryers or hair ironing. Silk protein is formed of two proteins: fibroin and 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. This composition is known to form a sheet structure to which is associated the comfortable touch of silk. Many of the amino acids of sericin have hydroxy groups which provides uncomparable moisturizing effect. Promois series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. There are also products with different preservatives. It is developed and manufactured in Japan by SEIWA KASEI.
