Keratin hydrolyzed

Chemical properties

Hydrolyzed keratin is a large protein molecule that is broken down after a chemical process in a manner such that it can penetrate the hair cuticle. It is sourced from a larger keratin molecule.Keratin is broken down by splitting its bond with the addition of hydrogen and hydroxide (water). At the end of the chemical process, the keratin is reduced into smaller fragments that the hair can absorb, thanks to its lower molecular weight.

The Uses of Keratin hydrolyzed

hydrolyzed keratin is a processed form of keratin that facilitates its use in skin care formulations.

Definition

Hydrolyzed keratin is a compound that can reverse the damage done to keratin. It is found in many hair care products and helps rejuvenate, strengthen, and moisturize the hair. In addition, this protein increases the smoothness of the hair.

Benefits

Hydrolyzed protein can repair and condition damaged hair. These protein hydrolysates strengthen hair fibers and reduce hair breakage.Protein hydrolysates are often added to hair coloring products for even color absorption.Hydrolyzed protein protects the hair from the damaging effects of permanent bleaching, waving, and straightening products.It improves the texture and natural structure of the hair and forms a protective coating to shield the strands.

Toxicology

Keratin Hydrolyzed sourced from sheep wool and hoof meal was non-toxic in oral studies in rats (i.e. the LD50 was greater than 40 ml/kg in a 20% solution). Keratin (MW = 8000 Da and 33,000 Da; buffalo horn/hoof source) and Hydrolyzed Keratin (MW = 310 Da; sheep wool source) were non-toxic in intravenous studies in mice.
