ABSTRACT:
New and improved thickeners for mixtures of one or more surface active agent include beta-hydroxyalkyl-terminally branched fatty acid amides. The new and improved thickeners achieve the same or better viscosity with lower amounts of mineral salts being required to be added. Concomitant benefits such as improved softening, lubricity, emulsifying and foam intensifying properties are also achieved. The thickeners and cleaner compositions containing them may also be prepared so that they do not contain nitrosamines, unlike prior art amide thickeners. A preferred thickener in accordance with the invention is 2-hydroxypropyl-isostearyl amide. A novel method for making the preferred thickener, so that it is substantially free of undesirable impurities is also provided.
