Abstract
Abstract Disclosed are detergent compositions containing an imidazoline component. These detergent compositions provide excellent cleaning as well as fabric care benefits. The imidazoline component consists of particles having an average particle diameter of from about 20 to about 200 microns. These granular detergent compositions may optionally contain clay materials, detergent builders, chelating agents, and/or peroxygen bleaching agents.
