Abstract

A film coating composition comprising a cellulosic polymer, an opacifying agent, and a fatty acid is disclosed herein. Also disclosed is a film coating composition comprising a cellulosic polymer, an opacifying agent, a plasticizing agent, and a polyol. The disclosed film coating compositions may be mixed with a solvent to produce a film coating suspension. The film coating suspension can be applied to a substrate, such as a nutritional supplement, pharmaceutical, tablet, capsule, softgel, granule, particle, food confectionary form, agricultural seed, and the like to form a film coating on the substrate. Methods of coating a substrate with the film coating suspensions are also provided.

Claims

1-32. -32. (canceled)

33. A film coating composition comprising:

a) about 3% to about 60% by weight hydroxypropyl methyl cellulose (HPMC);

b) about 3% to about 25% by weight of polyol;

c) a plasticizing agent; and

d) an opacifying agent.

34. The film coating composition of claim 33, wherein the polyol is selected from the group consisting of xylitol, maltitol, sorbitol, mannitol, erythritol, lactitol, and combinations thereof.

35. The film coating composition of claim 33, wherein the polyol comprises xylitol.

36. The film coating composition of claim 33, wherein the polyol is present in the composition in an amount from about 5% to about 20% of the composition by weight

37. The film coating composition of claim 33, wherein the plasticizing agent comprises glycerin, medium chain triglycerides, propylene glycol dicaprylate/dicaprate, polyethylene glycol, stearic acid, triethylcitrate, or a combination thereof.

38. The film coating composition of claim 33, wherein the plasticizing agent is present in the composition in an amount from about 1% to about 30% of the composition by weight.

39. The film coating composition of claim 33, wherein the opacifying agent comprises precipitated calcium carbonate.

40. The film coating composition of claim 33, wherein the opacifying agent is present in the composition in an amount from about 2% to about 18% of the composition by weight.

41. The film coating composition of claim 33, further comprising a fatty acid.
