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]
The molecule consists of a nitrogen atom with two methyl substituents and one hydrogen.Dimethylamine is a weak base and the pKa of the ammonium CH 3-NH + 2-CH 3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79).
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.
Lauryl Dimethyl Amine Oxide Market Poised for Growth with Increasing Demand in Personal Care and Cleaning Products | FMI Study NEWARK, Del, Oct. 31, 2024 (GLOBE NEWSWIRE) -- The global lauryl dimethyl amine oxide market , valued at USD 500 million in 2023, is expected to grow at a robust CAGR of 5.5% through 2033, reaching USD 850 million by 2033.
Alkyl dimethyl amine oxide (chain lengths C10–C16) is the most commercially used amine oxide. [3] They are considered a high production volume class of compounds in more than one member country of the Organisation for Economic Co-operation and Development ( OECD ); with annual production over 26,000, 16,000 and 6,800 tonnes (28,700, 17,600 ...
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.

Dimethylaminopropylamine (DMAPA) is a diamine used in the preparation of some surfactants, such as cocamidopropyl betaine which is an ingredient in many personal care products including soaps, shampoos, and cosmetics.
The amine is basic and undergoes quaternization with alkyl halides (e.g. hexyl bromide) to give quaternary ammonium salts: [4] [C 6 H 5 CH 2 N(CH 3 ) 2 + RX → [C 6 H 5 CH 2 N(CH 3 ) 2 R] + X − Such salts are useful phase transfer catalysts .
