Hydrolyzed Placental Protein

What is Hydrolyzed Placental Protein?

Hydrolyzed placental protein originates from the enzymatic breakdown of proteins extracted from mammalian placentas, most commonly ovine sources. This process yields smaller peptide chains that enhance solubility and bioavailability in formulations. It appears in hair care items like conditioners and shampoos, as well as skin products such as moisturizers and lotions. In products, it functions by adhering to hair cuticles and skin surfaces, creating a lightweight film that locks in hydration, reduces friction between strands, and improves overall texture. Its humectant properties draw moisture from the environment, while antistatic effects minimize charge buildup. Typically incorporated at low levels, it supports product stability and sensory appeal without altering viscosity significantly.
