Hydrolyzed Oat Protein

Gluten-Related

What is Hydrolyzed Oat Protein?

Hydrolyzed oat protein comes from the kernels of Avena sativa, the oat plant, where proteins are broken down through hydrolysis into smaller, water-soluble peptides. This process enhances its compatibility for cosmetic formulations, particularly in shampoos, conditioners, and moisturizers. In products, it works by depositing a thin film on hair shafts and skin surfaces, which helps to smooth cuticles, retain moisture, and minimize friction. Its amphoteric nature allows it to interact with both positive and negative charges, improving product spreadability and efficacy. Commonly featured in both rinse-off and leave-on items, it supports formulations aimed at enhancing texture without heavy residue. Derived naturally, it aligns with clean beauty trends while providing functional benefits in personal care routines.
