Since the previous paper 1 not only have a great many new products been marketed, but new groups of products have also been developed, such as the cation‐anion‐active compounds and the polyamides (not proteins). Both these new groups behave in many respects like polyethylene oxide compounds. and consequently are included according to the old system among the aminopolyethylene oxides. It has proved (losirable to subject this latter group to further subdivision. In addition to this, even before the previous paper a number of groups were known which a t the time, owing to lack of samples, had not, got been inclutled in the analytical system, e.g. phosphonium compounds, alkylnaphthalenephosplonates, akylamidoalkgl phosphates, alkylamidoalkanecarboxylates. The separation of tho cation‐activo amirics can now be rontinued much further than was possible at that time. These factors have induced me to reconsider the andysis of textile auxiliary products, and to attemptf to clessify them into a larger number of groups by means of the initial tests.
