Hydrolyzed milk protein works as a skin and hair conditioning agent and is found to a large extent in leave-on products, in the concentration of 0.00001-0.2%. It is a part of numerous products like body wash, lotions, creams, shampoos, conditioners, bar soaps, etc.
- Skin care: Since milk protein has good skin penetration, it aids in the restructuring of cells. It contains amino acids that can be both water- and fat-loving at the same time because they have two different groups attached to the same structure. As a result, they can attach to dirt and dead skin cells and then be washed away by water. It can therefore be used as a cleanser. Additionally, the milk protein maintains skin hydration and lessens allergic infections like rashes and skin discolorations. It can create a film on the skin's surface, preventing moisture from evaporating and keeping it in the skin. The skin becomes more hydrated, smoother, and lighter in color thanks to milk protein
- Hair care: Because of its anti-static, conditioning, strengthening, healing, and film-forming properties, it is used in hair care products. It works to repair the hair follicle while also lengthening and strengthening the hair. It prevents dryness by making it simple for water to enter the hair, keeping them hydrated. Due to its small molecule size, it can penetrate the hair, allowing them to benefit from all the protein they require for growth and health. Additionally, it restores damaged hair and aids in the development of strong, lustrous hair
