Abstract: The present invention relates to a novel ingestible film composition. More specifically, the invention is directed to a water-based, enzymatically-digested carboxymethylcellulose (CMC-Enz) film composition that is suitable for delivering pharmaceutical drugs, vitamins, natural products and other products to humans and animals. The invention further includes a method for manufacturing the novel composition. Advantageously, the film composition can accommodate an active ingredient in a quantity of up to approximately 60% of the overall weight of the final film.

Abstract: A process is described for coating a biodegradable item comprising the steps of dissolving from 10-25% ethylcellulose in 75-90% non-aqueous solvent to form a mixture; applying a layer of the mixture onto a surface of the item; and evaporating the solvent to form a coating of from 0.15 g to 0.30 g per 100 cm2 on a dry basis. The ethylcellulose may comprise Ethocel™, for example: Ethocel™ 20, Ethocel™ 45 or Ethocel™ 100. The process may be used to form a coating on biodegradable items that require a water barrier, for example cups, trays, or bowls made out of pressed starches, paper, or linted cellulose. Such items may appeal broadly as an environmentally-friendly packaging options.

Abstract: The present invention relates generally to protective barriers. More particularly, an aqueous oral gel is provided containing food-grade ingredients. The gel is used to protect or isolate soft tissue of the oral cavity, or teeth, during a dental procedure such as tooth whitening. The gel can be applied to a surface within the oral cavity as a liquid, and sets quickly to form a pliable protective barrier that can be carved away to expose a portion of a tooth, one or more teeth, or any area of the oral cavity on which the dental procedure is to be performed.
