ABSTRACT:
An environmentally degradable soap bar system (10) which includes a degradable insert member (14) centrally positioned and molded internal to a soap bar (12). The degradable insert member (14) is generally formed from a water soluble plastic composition, which may be selected from a group consisting of polyvinyl alcohol, hydroxypropyl cellulose, and polyethylene oxide. The degradable insert member (14) is substantially planar in contour and includes a plurality of through openings (24). Soap material is molded around the degradable insert member (14) and within the through openings (24). The soap material molded within the through openings (24) secures the degradable insert member (14) to the surrounding soap material and provides a mechanism for securing the degradable insert member (14) to the soap bar (12) independent of wear orientation imposed on the soap bar (12) during use. Subsequent to use, the degradable insert member (14) may be disposed of by generally dissolving the degradable insert member (14) in an aqueous solution.
