Dodecyldimethylamine Oxide (DDLO), also known as Lauryldimethylamine oxide (LDLO), or Lauramine oxide, is one of a common group of amine oxide based amphoteric surfactants, with a dodecyl(C12) alkyl tail. Like other amine oxide based surfactants, such as Cocamidopropylamine Oxide and Lauryl Amidopropyl Amine Oxide, DDLO has great anti-microbial properties, being effective against various common bacteria. 

DDAO is a strongly amphiphilic surfactant, with outstanding foaming ability, yet with poor thickening ability. All these properties make it a perfect choice of surfactant to formulate mousse or spray products, such as Hair Mousse, Foaming Hand Soap, Foaming Face Wash, and Carpet Cleaner Foam/Spray. These types of products require the formula to be liquid with low viscosity in the bottle, however, producing rich foam when being applied with a foam pump or spray.
