Description

Hydrolyzed Hair Keratin is a high-quality, water-soluble protein derivative obtained through the controlled hydrolysis of hair keratin. This process yields a mixture of low molecular weight peptides and amino acids that are readily bioavailable and compatible with various formulations. It serves as a premium functional ingredient for the personal care, cosmetic, and nutraceutical industries, prized for its ability to repair, strengthen, and moisturize. Its unique profile makes it an essential component for products targeting hair and skin rejuvenation.

Application

• Hair Care Products: A key active in shampoos, conditioners, masks, and serums to repair damaged hair, improve tensile strength, reduce breakage, and enhance shine and manageability.
• Skin Care & Cosmetics: Incorporated into creams, lotions, and serums for its moisturizing, film-forming, and protective properties, helping to improve skin elasticity and barrier function.
• Professional Salon Treatments: Used in intensive keratin-based smoothing and reconstructive treatments to restore hair's internal protein structure.
• Nutraceuticals & Dietary Supplements: Formulated into capsules or powders to support healthy hair, skin, and nails from within by providing essential sulfur-containing amino acids like cysteine.
• Color Cosmetics: Acts as a conditioning agent in mascaras, foundations, and lipsticks to improve product feel and skin adhesion.
• Pharmaceutical Topicals: Used in formulations for dermatological preparations aimed at wound healing and skin repair due to its biocompatibility.

Quality Control

Our Hydrolyzed Hair Keratin is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, peptide profile, and microbiological safety. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as protein content, amino acid profile, molecular weight distribution, and heavy metals. Production can adhere to ISO 22716 (Cosmetics-GMP) guidelines, and the material is suitable for use in compliance with global cosmetic regulations (EU, US FDA, China).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
