Description

Keratin Hydrolyzed is a high-quality, water-soluble protein derived from the controlled hydrolysis of keratin. This process yields a mixture of peptides and amino acids, making it a valuable functional ingredient for its film-forming, conditioning, and moisturizing properties. It is widely sought after by manufacturers in the personal care, cosmetics, and nutraceutical industries seeking to enhance product performance with natural, protein-based actives.

Application

• Hair Care Formulations: As a key conditioning agent in shampoos, conditioners, and hair masks to improve manageability, reduce static, and repair damaged hair.
• Skin Care Products: Incorporated into creams, lotions, and serums for its moisturizing and film-forming properties, helping to improve skin elasticity and texture.
• Cosmetic & Makeup: Used in mascaras, nail polishes, and foundations to enhance durability, adhesion, and overall product feel.
• Nutraceuticals & Dietary Supplements: Serves as a source of bioavailable amino acids like cysteine in supplements targeting hair, skin, and nail health.
• Animal Feed & Pet Care: Added to premium pet food and veterinary supplements to support coat health and keratin synthesis.
• Technical & Industrial Uses: Employed in biodegradable films, adhesives, and specialty coatings where a natural protein binder is required.

Quality Control

Our Keratin Hydrolyzed is produced under strict quality management systems. Each batch undergoes rigorous testing to ensure it meets specifications for key parameters such as protein content, peptide profile, and microbiological purity. Certificates of Analysis (COA) are provided with every shipment. We can support compliance requirements for COSMOS, ISO 22716 (Cosmetics GMP), and other relevant quality standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent moisture absorption and caking.
