Keratin Hydrolysate

CAS: 69430-36-0                                                                

Keratin, a fibrous protein forming main structural constituent of feather, hair, wool, horn, hoof etc., is abundantly available as a by-product from poultry, slaughterhouse, tanning and fur processing industry& which manufactured by Fermentation process.


  • Revitalizes the hairs natural protective layer and rebuilds tensile strength
  • Returns elasticity and reduces breakage
  • Reduces hair damage from harsh chemicals
  • Acts also as a protective care substance on the skin

Keratin hydrolysates (KHs) are established standard components in hair ,nail,skincosmetics. Understanding the moisturizing effects of KH is advantageous for skin-care cosmetics.

The highly favourable properties of keratin hydrolysates are attributed to the wide distribution of keratin hydrolysates molecular weights; low-molecular weight fractions easily penetrate the skin, while high-molecular weight fractions form a protective film on the epidermis.

If adding keratin hydrolysate into an ointment base increases hydration of the skin and improves skin barrier function, or diminishes trans-epidermal water loss.

The major function of keratin cuticle is to protect the cortex of the hair from damage caused by several factors including heat, chemicals and daily maintenance. Keratin is a fibrous and insoluble protein with excellent mechanical properties.

Skin moisturisation, elasticity, feel and appearance can all be improved through the topical application of protein hydrolysates. Recent studies suggest that supplementing intercellular lipids of the stratum corneum can enhance the functioning of the skin.
