Abstract
The present invention is directed to a personal cleansing product which can be sized as a single use personal cleansing product. The cleansing product is an extruded foam product which can disintegrate upon contact with water when used in the standard fashion to wash. As the foam disintegrates, the cleansing agent held in the foam matrix is released. The disintegration of the product can take place slowly, over a period of time such that when an individually sized cleanser is used to scrub until it completely disintegrates, scrubbing duration is long enough to ensure desired levels of cleanliness have been attained. Alternatively, the product can disintegrate immediately, and release all of the soap at essentially one time. The product is an extruded foam expanded from a mixture of a natural starch, a nucleating agent, a water soluble disintegrant, a blowing agent, a water soluble polymer, and a soap base. Optionally, the foam can include a destructured starch, natural, dyes, fragrances, and the like to obtain specific product characteristics.
