Oxides, amine alkyl dimethyl

AHphatic amine oxides such as alkyl dimethyl amine oxides and aLkylbis(2-hydroxylethyl)amiae oxides range from practically nontoxic to slightly toxic (79). Reported LD qS range from 1.77 g/kg to 6.50 g/kg. The commercial concentrated products are primary skin and eye irritants. At concentrations of 2%, these products may be considered as nonirritating to the skin or eye.

These alkyl dimethyl amine oxides are used as foam stabilizers primarily in light-duty liquids and shampoos where the major active ingredient is either an alcohol ether sulfate or an alcohol sulfate. The alkyl group is usually C19 to C.. which gives the best overall foam stability (3). 12 14... 

In acid solutions, the amino group is protonated and acts as a cationic surfactant, whereas in neutral or alkaline solution the amine oxides are essentially nonionic in character. Alkyl dimethyl amine oxides are water-soluble up to Cj, alkyl chain. Above pH 9, amine oxides are compatible with most anionics, but at pH 6.5 and below some anionics tend to interact and form precipitates. In combination with anionics, amine oxides can be used as foam boosters (e.g., in shampoos).
