● What is Hydrolyzed Keratin ?
Hydrolyzed Keratin (CAS No. 69430-36-0) is a natural protein derivative extracted from animal hair (such as wool, chicken feathers, duck feathers) or plant meal (such as soybean meal, cotton meal) by bio-enzyme or chemical hydrolysis technology. Its preparation process includes raw material pretreatment, enzymatic hydrolysis or acid-base hydrolysis, filtration and spray drying, and finally forms a short peptide structure with a molecular weight of about 173.39 and a molecular formula of C₂H₂BrClO₂.
In recent years, with the rise of green chemistry, bio-enzymatic cleavage technology has become a mainstream process due to its high efficiency and low pollution characteristics. For example, proteases optimized by genetic engineering can accurately cut keratin chains to generate peptides with smaller molecular weight and stronger biological activity, significantly improving its application potential in cosmetics and medicine.
Hydrolyzed keratin is white to light yellow powder or transparent liquid with a slight special smell. Its core physical and chemical properties include:
Solubility: easily soluble in water and ethanol, with a wide pH range (5.5-7.5), suitable for a variety of formulation systems.
Stability: High temperature resistant (melting point is about 57-58℃), but needs to be stored away from light to prevent oxidative degradation.
Ingredient characteristics: rich in cystine (about 10%), branched-chain amino acids (BCAA) such as leucine and valine, and umami amino acids such as glutamic acid, with high nutritional value.
The molecular weight of the processed hydrolyzed keratin is as low as 500-1000 Daltons, which can penetrate the hair surface, combine with the natural keratin in the hair, form a protective film, and significantly improve the repair effect.
● What Are The Benefits Of Hydrolyzed Keratin ?
Hydrolyzed keratin exhibits multiple biological activities due to its unique amino acid composition and short peptide structure:
1. Hair Care And Repair:
- Repair damaged hair: Fill the cracks in the hair cuticle and reduce split ends. Clinical trials have shown that the use of a conditioner containing 0.5%-2% hydrolyzed keratin can increase the breaking strength of hair by 30%.
- Moisturizing and glossing: Hydrolyzed Keratin forms a hydrophilic film on the surface of the hair to lock in moisture and improve frizziness. It is often used in high-end hair oil products.
2. Skin Care:
- Anti-inflammatory and soothing: Inhibits the release of skin inflammatory factors and relieves sensitive reactions caused by chemical stimulation (such as surfactants).
- Antioxidant synergy: Removes free radicals, delays photoaging, and can enhance the anti-aging effect when combined with vitamin E.
3. Nutritional Supplement:
- As a high-quality protein source, it is used in animal feed to improve hair quality, or as a food additive to enhance the flavor of the product.
● What Are The Applications Of Hydrolyzed Keratin ?
1. Cosmetics And Personal Care:
- Hair care products: Add 1%-5% to shampoo, conditioner, and hair mask to repair damage caused by perming and dyeing, such as the core ingredients of brands such as L’Oreal and Schwarzkopf.
- Skin care products: Used as a moisturizer in creams and essences, especially suitable for sensitive skin repair.
2. Food And Feed:
- Functional food: As a dietary supplement or flavoring agent, added to energy bars and beverages to provide essential amino acids.
- Animal nutrition: Improve the quality of livestock and poultry fur, improve the redness of pig skin, and reduce breeding costs.
3. Medicine And Industry:
- Wound dressings: Use its biocompatibility to promote cell regeneration and accelerate the healing of burns or chronic ulcers.
- Textile processing: Enhance fiber softness and durability, and use it in high-end fabric production.
