Summary
Laboratory measurements of detergency were made on mixtures of sodium salts of sulfated hydrogenated tallow alcohol (X), disodium salts of α-sulfonated hydrogenated tallow acids (Y), sodium dodecylbenzenesulfonate (Z), and a builder (B) using three different kinds of standard soiled cotton. Component X was the most important, and mixtures not containing X were generally inferior detergents. Built XY mixtures were better than XZ mixtures with one kind of soiled cotton (cloth I). Built XZ mixtures were better than XY mixtures with another soiled cotton (cloth III).
The results, based on laboratory measurements of detergency using standard soiled cotton, are suggestive rather than conclusive. Partial substitution of X by Y or Z, or by both Y and Z, may be possible without loss in detergency.
