What is hydrolyzed keratin peptide?
Hydrolyzed keratin collagen is formed after enzymatic hydrolysis, and its molecular structure and molecular weight change, which changes its functional properties such as water absorption, solubility and water retention. Hydrolyzed collagen with a larger molecular weight has a stronger hydrophobic effect and can better maintain the molecular configuration, so it has better oil absorption, emulsification and emulsification stability in the two-phase system. Therefore, hydrolyzed collagen with a lower degree of hydrolysis and a larger molecular weight is required to be added to oily cosmetics. However, moisturizing cosmetics require the addition of hydrolyzed collagen with high degree of hydrolysis and small molecular weight, whose polar groups can form polar forces such as hydrogen bond and ionic bond, and have good water absorption, solubility and water retention.  …
