It appears that for each snrfactant system, AG° is a linear fnnction of the number of carbon atoms of the solubihzate see, for example, the work by DeLisi and co-workers who have stndied alcohol solubilization in SDS, dodecyltrimethylammonium bromide, and dodecyldimethylamine oxide.In this work we prefer to plot AG" as a fimction of the niunber of CH2 groups of the solubilizate. Tables 6.2 through 6.6 contain data for several homologous series in anionic, cationic, and nonionic surfactants, and on this basis the following relationship has been tested ... 

The table shows that, in dodecyldimethylamine oxide production, the use of USA storage grade H202 reduces nitrosamines by a factor of 3. Addition of a phosphonate based H202 stabilisation package reduces this level by a factor of 5 whilst increasing yield and conversion.

Aliphatic tertiary amines can be oxidised to A-oxides using 35% w/w H2O2 alone [149], typically in water at 1.1 1.0 molar ratio for 4-5 hours at 60-65°C (example for dodecyldimethylamine). This reaction is employed worldwide on a scale in excess of 25 ktpa, to make fatty amine oxides, which are used as surfactants [150] in personal care products (e.g. shampoos) and as thickener components in hypochlorite household bleach. N-Methylmorpholine A-oxide has a growing use as a solvent for cellulose in the manufacture of a new cellulose fibre [151]. Substituted oxazolidine N-oxides are relatively new user-friendly biocides [152]. A further application involving an aliphatic tertiary amine oxide intermediate is glyphosate manufacture (section 9.5.1.7.6).
