Abstract

An edible dry-powder formulation of a film coating for pharmaceuticals and confectioneries using gum acacia as a low-cost film former is provided. A cellulosic polymer such as hydroxypropyl methylcellulose is used in addition to the gum acacia. A plasticizer such as propylene glycol is also added. The resulting formulation is a dry, free flowing powder that can be put into solution and applied to a tablet or other substrate without an extended waiting period. The resulting film coating is clear, shiny, durable and extremely economical. Because the formulation is a dry powder, it has along shelf life and low shipping costs.

Description

technical field [0001] Generally, the present invention relates to a film coating composition and a method for preparing the same, and in particular, the present invention relates to an edible dry powder film coating composition and a method for coating medicine and candy. Background technique [0002] Cellulosic polymers such as hydroxypropylmethylcellulose ("HPMC") are well known in the art as aqueous film coatings for tablets and the like. Although HPMC (and other similar polymers) are commonly used, it is more expensive. Another parenteral coating alternative is sugar coating. While sugar coating is less expensive, prevents moisture migration into the tablet mass, and masks unpleasant tastes, it is not ideal as a coating for all purposes. For example, sugar coatings cannot be applied as thinly as film coatings, and are not clear and non-caloric. In addition, sugar coatings also have a higher probability of cracking than film coatings. Finally, the icing is usually mi...
