Description

Keratin CAS NO 68238-35-7 is a fibrous structural protein that serves as a key building block for hair, skin, nails, feathers, horns, and wool. Its unique amino acid composition, rich in cysteine which forms disulfide bonds, provides exceptional strength, resilience, and protective properties. This makes it a highly valuable ingredient for manufacturers in the cosmetics, personal care, nutraceutical, and biomedical industries seeking to enhance product performance with natural, bio-compatible materials.

Application

• Cosmetic & Hair Care Formulations: Used in shampoos, conditioners, and hair masks to repair damaged hair, improve elasticity, and provide a protective coating.
• Skin Care Products: Incorporated into creams and serums for its moisturizing and film-forming properties, helping to improve skin texture and barrier function.
• Nutraceuticals & Dietary Supplements: Sourced for capsules and powders aimed at supporting healthy hair, skin, and nail growth from within.
• Biomedical & Tissue Engineering: Explored as a scaffold material for wound healing applications and regenerative medicine due to its biocompatibility.
• Animal Feed & Nutrition: Utilized as a protein supplement in specialized feed formulations.
• Industrial Applications: Employed in the production of biodegradable films, adhesives, and specialty coatings.
