Abstract
Abstract Highly useful amidoamine oxides are provided which are derived from polymeric fatty acids, particularly, dimer and trimer acids obtained by the polymerization of C18 unsaturated monocarboxylic acids. Aqueous solutions and dispersions of the amidoamine oxides of this invention can be used in a variety of formulations to impart desirable properties. They are particularly advantageous for use in cleaning formulations and shampoo products and when included in anionic and cationic laundry detergents have been found to soften the laundered articles.
