**Introduction to Hydrolyzed Keratin** Hydrolyzed Keratin is a premium protein derived from natural keratin, broken down into smaller peptides for enhanced absorption and effectiveness. Rich in amino acids like cysteine, it strengthens, repairs, and revitalizes hair, skin, and nails by replenishing lost proteins and improving elasticity. Ideal for damaged or brittle hair, it smooths cuticles, reduces breakage, and boosts shine while promoting long-term resilience. In skincare, it supports moisture retention and barrier repair. Lightweight and easily incorporated into serums, shampoos, and conditioners, hydrolyzed keratin is a versatile, science-backed ingredient for nourishing beauty formulations. Suitable for all hair types, it delivers deep restoration without weighing strands down.
Preparation Process: **Preparation Method of Keratin Hydrolyzed:** Keratin hydrolyzed is prepared by alkaline or enzymatic hydrolysis of keratin-rich materials (e.g., wool, feathers, or hair). For alkaline hydrolysis, the substrate is treated with sodium hydroxide (NaOH) or potassium hydroxide (KOH) at elevated temperatures (50–100°C) for several hours. Enzymatic hydrolysis uses proteases (e.g., papain or keratinase) under mild conditions (pH 7–9, 37–60°C). The mixture is then neutralized, filtered, and concentrated. Further purification may involve dialysis or ultrafiltration to remove salts and large peptides. The final product is spray-dried or lyophilized to obtain a powdered form. Hydrolysis conditions are optimized for desired peptide size and solubility.
Usage Scenarios: Keratin hydrolyzed is widely used in cosmetics and personal care products for its ability to strengthen and repair hair, nails, and skin. It acts as a conditioning agent, improving moisture retention, elasticity, and texture in damaged hair. In shampoos, conditioners, and hair masks, it helps reduce breakage and frizz while enhancing shine. For nails, keratin hydrolyzed fortifies brittle nails, promoting growth and durability. In skincare, it supports skin barrier function, aiding in hydration and reducing signs of aging. Additionally, it is used in medical and veterinary applications for wound healing and tissue repair due to its biocompatibility and regenerative properties.
