Abstract: | Long chain alkyldimethylamine oxides in detergent mixtures have not only been difficult to determine but also interfere with anionic active analysis by the usual quaternary titration with methylene blue indicator. Titration methods have been devised for the quantitative analysis of amine oxides and anionic actives in the presence of each other and low molecular wt sulfon-ates. A gas Chromatographic method has also been developed for determining molecular distribution in alkyldimethylamine oxide mixtures. Analytical data are presented for a series of alkyldimethylamine oxides of different mol wt and for several experimental detergent formulations. The titration method is rapid and amenable to both solid and liquid detergent formulations. Presented at the AOCS Meeting in Minneapolis, 1963. |
