Promois™ EF-118(IS) is an acylated derivative of hydrolyzed silk protein. This is oil-soluble and it can be formulated into waterless formulae such as hair oil. 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. The amino acids of sericin have many hydroxyl groups which provides uncomparable moisturizing effect. This product is preservative free. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.
