Hydrolyzed keratin powder Cas.69430-36-0, a natural hair conditioning and repairing agent & skin care active ingredient derived from natural feathers through advanced bio-enzyme digestion technology. Classified as type V collagen, this preservative-free cosmetic raw material boasts high keratin affinity, superior skin/hair penetrability, and excellent water solubility (40M g/100g water)—a must-have multi-functional ingredient for organic personal care products and the high-end cosmetic manufacturing industry. With a flexible formula that elevates product appearance, It is rapidly absorbed by hair and skin to prevent damage, lock in moisture, and relieve irritation caused by surfactants in cosmetic formulations, making it the ideal choice for clean beauty and natural skincare/haircare product lines.
Hydrolyzed keratin Core Functional Benefits | Cosmetic Ingredient for Anti-Aging & Repair
1. Superior Moisture Retention for Skin & Hair | Hydrating Cosmetic Raw Material

The main cross-linked structure of keratin is cysteine. Disulfide bonds can be opened by enzymatic hydrolysis. Its abundant cysteine and other amino acids have great effect on repairing, moisturizing and conditioning the skin, making the stratum corneum smooth and flexible.
Hydrolyzed Keratin features exceptional skin and hair bio-affinity, penetrating the skin stratum corneum and hair cuticles to deliver long-lasting moisture retention and hydration. For facial and body skin, daily application (3ml keratin solution morning and evening) drives a significant increase in skin moisture levels, solving dry, rough skin concerns for moisturizers and serums. For hair care products, it prevents moisture loss and dryness, reduces surfactant-induced irritation, and boosts the hydrating performance of shampoos, conditioners, and hair masks—a key hydrating ingredient for professional hair care lines.
2. Advanced Skin Repair & Conditioning | Anti-Aging Skin Care Ingredient


The core cross-linked structure of keratin is cysteine; enzymatic hydrolysis gently opens disulfide bonds, releasing abundant cysteine and essential amino acids that repair, moisturize, firm, and smooth the skin. This active ingredient revitalizes the skin stratum corneum, enhances its flexibility and elasticity, and improves overall skin texture—targeting dull, aging, and damaged skin for anti-aging creams, repair serums, and mild cleansers. A premium choice for anti-aging cosmetic formulations and sensitive skin care products.
3. Natural Antioxidant & Free Radical Elimination | Skin Defense Cosmetic Ingredient

As a 100% natural antioxidant cosmetic ingredient, Hydrolyzed Keratin directly addresses oxidative stress—the primary cause of skin aging and dullness. It boosts the body’s endogenous antioxidant activity, strengthens the skin’s natural defense barrier, and increases the production of peroxide dismutase (SOD) and glutathione—two critical enzymes that neutralize oxidative stress. Cysteine mercaptocyls eliminate harmful free radicals in the body, while carboxyl and hydroxyl functional groups bind to pigments and heavy metals, preventing hair damage from copper ions in domestic water. Perfect for antioxidant skincare products and anti-aging hair care formulations.
4. Professional Hair Repair & Elasticity Enhancement | Salon-Grade Hair Care Ingredient
Damaged hair (from coloring, perming, heat styling) suffers from roughness, poor gloss, and low elasticity—Hydrolyzed Keratin is the ultimate repair ingredient for damaged hair. It repairs broken hair scales by reforming disulfide cross-links (via partial oxidation of cysteine residues) and forms a transparent, elastic, and durable protective film on the hair surface—boosting hair strength, gloss, and manageability. Lab-tested hair repair performance (1:50 bath ratio, 30mins soak, 24h balance):
| Hair Sample | Initial Elasticity | Elasticity after Hydrolyzed Keratin Treatment |
| Damaged Hair | 53.90% | 57.60% |
| A staple ingredient for salon-grade hair repair masks, leave-in conditioners, and anti-damage hair serums. |
5. Natural UV Absorption for Hair | Chemical-Free UV Protection Ingredient

Adding a 2% Hydrolyzed Keratin solution to hair care products enables the ingredient to absorb harmful ultraviolet rays (200nm-300nm), providing natural UV protection for hair. With strong, long-lasting adsorption on hair strands, it acts as an ideal natural sunscreen additive for hair care—100% free of toxic side effects and a safer alternative to chemical sunscreens. Perfect for UV protection hair sprays, summer hair care lines, and color-protecting shampoos/conditioners.
