What is Hydrolyzed Cottonseed Protein?

Hydrolyzed Cottonseed Protein comes from the seeds of the cotton plant (Gossypium species), where native proteins undergo hydrolysis—a process that breaks them into smaller, water-soluble peptides. This form allows easy blending into rinse-off and leave-on cosmetics, mainly hair care like conditioners and shampoos, but also skin products such as lotions and creams. Functionally, it adheres to the hair cuticle or skin surface, creating a flexible film that minimizes friction between strands, boosts manageability, and prevents moisture loss. For skin, it supports barrier function by promoting hydration and smoothness. Its mild, plant-based nature suits formulations aiming for lightweight conditioning without greasiness, appealing to users preferring protein-derived actives over synthetic polymers.
