Foamed cleanser with suspended particles

Abstract

One aspect of the invention is a new foam which includes a liquid having a plurality of bubbles therein and a plurality of particles suspended therein. The foam is made in a dispenser that suspends the bubbles in the liquid. The liquid may be a single liquid with particles therein or may be made from two liquids which are mixed together. The particles may be such that, prior to foaming the particles sink, float or are suspended in the liquid.
