Hydrolyzed Milk Protein is a milk-derived cosmetic protein ingredient produced by hydrolyzing milk proteins into smaller peptides and protein fractions. The hydrolysis process improves the ingredient’s formulation versatility and makes it suitable for a wide range of hair care, skin care, bath and personal care products.
Hydrolyzed Milk Protein is valued for its conditioning, film-forming, moisturizing and skin-softening properties. It can help provide a smooth, soft and conditioned sensory feel to hair and skin.
It is particularly suitable for premium hair conditioners, shampoos, hair masks, moisturizing creams, lotions, facial care products and protein-enriched personal care formulations.
