Abstract
The biodegradable abrasive compositions consist of a plant-based natural abrasive agent, calcium carbonate, polymeric material, and a binder. The natural abrasives may consist of a plant-based cereal grains or fibers. The polymeric materials of the preferred embodiments include starch and poly-vinyl alcohol, either alone or in combination. The products associated with the biodegradable abrasive compositions are gently abrasive and readily disposable films or coatings. The products are designed to maximize the use of agricultural bi-products and avoid harm the environment.
