Sodium Lauroyl Hydrolyzed Silk is a silk-based anionic surfactant and is designed for higher-end brands, products, and customers enjoying silk as part of the cleansing process and label content. It combines silk polypeptides into a luxurious cleanser that is sure to please the most discriminating client.

Sodium Lauroyl Hydrolyzed Silk is an acylated polypeptide – sodium condensate of lauric acid and silk polypeptide obtained by hydrolysis of fibroin protein in silk filament.  Its average molecular weight is about 500.

Sodium Lauroyl Hydrolyzed Silk is a light yellow to light brown transparent or cloudy liquid, with a faint characteristic odor. It is fully soluble in water and partially (70%) in alcohol.

Thanks to a high level of biodegradability compared with traditional surfactants, Sodium Lauroyl Hydrolyzed Silk is also safe for the environment.  It is usually used in 0.5 - 5.0% concentrations in shampoos, body and hand soaps, face washes, and shaving foams.
