Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide–based zwitterionic surfactant, with a C 12 (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. [ 4 ]
In the strict sense, the term amine oxide applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary amines. Examples of amine oxides include pyridine-N-oxide, a water-soluble crystalline solid with melting point 62–67 °C, and N-methylmorpholine N-oxide, which is an oxidant.
It is raw material for the production of many agrichemicals and pharmaceuticals, such as dimefox and diphenhydramine, respectively. The chemical weapon tabun is derived from dimethylamine. The surfactant lauryl dimethylamine oxide is found in soaps and cleaning compounds. Unsymmetrical dimethylhydrazine, a rocket fuel, is prepared from ...
It is a colourless liquid although commercial samples can appear yellow and exhibit an amine-like odour. [citation needed] DPTA is a widely applied ingredient in many products, such as in surfactants, antimicrobials, preservatives, emulsifiers, corrosion inhibitors, chilling liquids, antistatics (e.g., in hair products), and dispersing agents.

Fatty alcohol are converted to their ethoxylates by treatment with ethylene oxide: [6] RCH 2 OH + n C 2 H 4 O → RCH 2 (OCH 2 CH 2) n OH. The resulting fatty alcohol ethoxylates are important surfactants. Another large class of surfactants are the sodium alkylsulfates such as sodium dodecylsulfate (SDS).
Myristamine oxide is an amine oxide based zwitterionic surfactant with a C 14 (tetradecyl) alkyl tail. It is used as a foam stabilizer and hair conditioning agent in some shampoos and conditioners .
The most common biological zwitterionic surfactants have a phosphate anion with an amine or ammonium, such as the phospholipids phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, and sphingomyelins. Lauryldimethylamine oxide and myristamine oxide are two commonly used zwitterionic surfactants of the tertiary amine oxides ...
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +.
