Lauryldimethylamine oxide, also known as dodecyldimethylamine oxide or DDAO, (also N,N-Dimethyldodecylamine N-oxide), is an amine oxide surfactant. It is one of the most frequently-used surfactants of this type.[1]

At high concentrations, DDAO forms liquid crystalline phases.[2] Despite having only one polar atom that is able to interact with water - the oxygen atom (the quaternary nitrogen atom is hidden from intermolecular interactions), DDAO is a strongly hydrophilic surfactant: it forms normal micelles and normal liquid crystalline phases. High hydrophilicity of this surfactant can be explained by the fact that it forms very strong hydrogen bonds with water: the energy of DDAO - water hydrogen bond is about 50 kJ/mol.[3]
