The Amphoteric Surfactant ,-Dimethyldodecylamine N-Oxide Unfolds β-Lactoglobulin above the Critical Micelle Concentration.

Understanding the interactions between surfactants and proteins is important for the formulation of consumer products as surfactant binding can alter protein activity and stability. Additionally, the structure of the protein-surfactant complex can influence surface activity, which is important for emulsion and foam development. ,-Dimethyldodecylamine N-oxide (DDAO) is an amphoteric surfactant that is nonionic at high pH.
