What is Hydrolyzed Keratin?

Hydrolyzed keratin, from the perspective of chemical raw materials, is a specially treated natural protein derivative. Keratin is the main structural protein that constitutes animal hair, nails, feathers, hooves, horns and scales and other hard tissues. It is mainly composed of two major categories: α-keratin and β-keratin. It is rich in cysteine ​​residues and forms a highly stable fiber structure through a large number of disulfide cross-links.

Uses of Hydrolyzed Keratin

1. Cosmetics industry
Moisturizing and repairing: Hydrolyzed keratin is rich in a variety of hydrophilic amino acids, such as serine and glutamic acid. These ingredients can effectively bind moisture, provide moisturizing effect to the skin and reduce water loss. At the same time, small molecule peptide chains can penetrate the surface layer of the skin, promote the repair of the skin barrier, and reduce dryness and roughness.
Anti-aging: Amino acids such as cystine and tyrosine help promote collagen synthesis, increase skin elasticity and firmness, reduce fine lines and wrinkles, and combat the skin aging process.
Hair care products: Hydrolyzed keratin peptides can penetrate into the hair, fill the gaps between hair scales, reduce damage, enhance hair strength, improve gloss and suppleness, and have a significant repair effect on damaged hair.

2. Agriculture
Plant growth promoter: The amino acids in hydrolyzed keratin and its derivatives are used as fertilizer additives to stimulate crop growth, enhance plant stress resistance, and improve yield and quality. The direct supply of amino acids can promote plant metabolism and enhance photosynthesis.
Biopesticides: Some keratin peptides have biological activity and can be used as natural fungicides and plant growth regulators to prevent and cure certain diseases while promoting healthy plant growth.

3. Food and feed industry
Nutritional supplement: As a high-quality protein source, hydrolyzed keratin can be used as a food additive or nutritional supplement to improve the nutritional value of food, especially in amino acid-balanced formula foods and special medical foods.
Animal feed: Adding hydrolyzed keratin to animal feed can promote the growth and development of livestock and poultry, enhance the gloss of fur, improve meat quality, and increase breeding efficiency. Direct supplementation of amino acids aids in muscle and tissue repair in animals.

4. Medicine and health products
Amino acid supplement: Hydrolyzed keratin, as a complex source of amino acids, can directly supplement the essential amino acids required by the human body, support muscle recovery, and enhance immunity. It is especially suitable for athletes and convalescent patients.
Research on bioactive peptides: Small molecule peptides in hydrolyzed keratin have specific biological activities, such as antioxidant, anti-inflammatory, immune regulation, etc., and are potential raw materials for the development of new drugs and health products.

Advantages and Characteristics of Hydrolyzed Keratin

1. Reduced molecular weight and enhanced bioavailability
Principle: Through acid, alkali or enzymatic hydrolysis, the macromolecular keratin is broken down into smaller peptides or even amino acids, which reduces the molecular weight and makes it easier for these small molecules to penetrate the surface of the skin or hair, thereby improving their bioavailability and absorption efficiency.

2. Rich amino acid spectrum
Features: A variety of amino acids are released during the hydrolysis process, including but not limited to cystine, tyrosine, serine, etc. These amino acids are key components for maintaining skin and hair health and participate in moisturizing, repairing and growing processes.

3. Excellent moisturizing and repairing properties
Mechanism: Contains a large number of hydrophilic amino acids, which can attract and lock in moisture, enhance the moisturizing ability of skin and hair, and at the same time, peptides can penetrate into the epidermis or hair scales, promote the generation of natural moisturizing factors, repair damaged parts, and reduce dryness and split ends.

4. Promote the structural reconstruction of skin and hair
Effect: Since keratin itself is the main protein that constitutes skin and hair, the hydrolyzate can supplement the protein loss caused by environmental factors or physical and chemical treatments, help rebuild and strengthen the natural barrier of skin and hair, and enhance its strength and elasticity.

5. Forming a protective barrier
Application: In hair care, hydrolyzed keratin can form a thin protective film on the surface of hair, reducing external damage such as heat treatment, UV radiation and chemical treatment, while giving hair a natural luster.

6. Wide range of biocompatibility and safety
Properties: Keratin derived from natural sources (such as animal hair, feathers or plant protein), after mild chemical treatment, maintains good biocompatibility, low irritation to skin and eyes, suitable for all skin types, including sensitive skin.

7. Versatility
Application range: In addition to its wide application in personal care and cosmetics (such as skin care products, shampoos, and conditioners), hydrolyzed keratin is also used as an animal feed additive to promote animal fur health, and as a nutritional supplement in pharmaceutical and health products, reflecting its cross-field application value.
