US Patent 8084409 Microdermabrasion soap bar compositions and methods of preparing same

A light-colored soap bar composition for at-home microdermabrasion comprising from approximately 8% to approximately 15% by weight of an abrasive comprising magnesium oxide, having a mean particle size diameter from approximately 120 to approximately 200 micrometers, and from approximately 0.5% to approximately 3.5% total dispersing agents by weight, which help to disperse the abrasives uniformly within the soap bar. The dispersing agents comprise oil and butter components which help to uniformly incorporate the abrasives into the soap bar composition without having to significantly alter the foamability and integrity of the soap bar.
