High-Quality Hydrolyzed Keratin Protein Powder Cosmetic Grade for Hair Repair Ingredient Manufacturer, Suppliers
Product Description
Hydrolyzed Keratin Protein is a water-soluble small-molecule keratin peptide obtained by enzymatic hydrolysis of natural keratin derived from wool, feathers, or animal horn. It is highly concentrated in cysteine and multiple essential amino acids with low molecular weight, allowing it to quickly penetrate the hair cuticle and epidermal skin layers that regular large keratin molecules cannot reach.
Tested strictly by HPLC, the active protein content reaches 90% minimum. Free testing samples are available upon request, fully supported by COA and MSDS documentation.
Highly water-soluble cosmetic grade raw material. Maintains exceptional stability in surfactant systems, fully compatible with shampoo, conditioner, hair mask, essence, lotion, and cream systems.
Small-molecule keratin peptides deeply penetrate the hair cuticle to replenish porous cavities within the hair cortex. Effectively restores lost keratin from chemical perming, dyeing, and thermal styling while visibly reducing split ends and breakage.
