Hydrolyzed Lupine Protein

What is Hydrolyzed Lupine Protein?

Hydrolyzed lupine protein is derived from the seeds of lupin plants (Lupinus species), legumes native to the Mediterranean and grown worldwide for their nutrient-rich seeds. The ingredient undergoes hydrolysis, where enzymes or acids break down the plant's proteins into smaller peptides and amino acids, improving solubility and skin compatibility. Typically used in rinse-off and leave-on hair care like conditioners and shampoos, as well as skin moisturizers and lotions, it works by depositing on hair cuticles and skin strata. This creates a thin film that smooths surfaces, minimizes friction, boosts hydrophobicity, and aids moisture binding, enhancing overall product sensorial qualities.
