Hydrolyzed Potato Protein

What is Hydrolyzed Potato Protein?

Hydrolyzed potato protein comes from the tubers of Solanum tuberosum, a common potato variety. Proteins are extracted and broken down through hydrolysis into smaller peptides and amino acids, making them water-soluble and suitable for cosmetic formulations. Primarily featured in hair care items like conditioners and shampoos, it also appears in skin products such as lotions and creams. In formulations, it works by forming a protective film on hair shafts or skin surfaces, which helps retain moisture, smooth cuticles, and minimize friction between strands. This action contributes to better product spreadability and sensory feel, while its cationic nature at certain pH levels aids in static reduction by neutralizing surface charges.
