Definition
ChEBI: Dodecyldimethylamine N-oxide is a tertiary amine oxide resulting from the formal oxidation of the amino group of dodecyldimethylamine. It has a role as a plant metabolite and a detergent. It derives from a hydride of a dodecane.
What are the applications of Application
Lauryldimethylamine oxide(LDAO) is mainly used in cosmetic and personal care product formulations, particularly in hair care products as a foaming agent, fragrance ingredient, viscosity builder, stabiliser, conditioner, emulsifier, wetting agent and antistatic agent. It is also a biochemical reagent and can be used as a biological material or organic compound for life science related research.
General Description
Crystalline solid.
Air & Water Reactions
Hygroscopic .
Reactivity Profile
LDAO is less basic than the tertiary amine from which LDAO is derived, but still reacts with strong acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Fire Hazard
Flash point data for LDAO are not available. LDAO is probably nonflammable.
Flammability and Explosibility
Not classified
Biochem/physiol Actions
LDAO can be used to disrupt phospholipid bilayer of cells.
Purification Methods
Crystallise the oxide from acetone or ethyl acetate. [Bunton et al. J Org Chem 52 3832 1987, Beilstein 4 III 410, 4 IV 798.]
