Abstract

Abstract The present invention relates to nonabrasive thickened aqueous-based personal cleansing compositions. These compositions utilize insoluble micronized cleansing particles of defined particle size that are not tactilely perceived by the user during the cleansing process, and yet which provide improved cleansing performance from the composition.
