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. A film coating composition comprising:

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

b) about 1% to about 30% by weight plasticizing agent;

c) inulin; and

d) an opacifying agent.

2. The film coating composition of claim 1 comprising a fatty acid.

3. The film coating composition of claim 1, wherein the opacifying agent comprises precipitated calcium carbonate.

4. The film coating composition of claim 2, wherein the fatty acid comprises oleic acid.

5. The film coating composition of claim 1, further comprising a film forming agent.

6. The film coating composition of claim 5, wherein the film forming agent comprises an ionic cellulosic polymer.

7. The film coating composition of claim 6, wherein the ionic cellulosic polymer comprises sodium carboxymethylcellulose.

8. The film coating composition of claim 5, wherein the hydroxypropyl methyl cellulose and the film forming agent are present in a ratio of about 3:

1 by weight.

9. A film coating suspension comprising the film coating composition of claim 1 and a solvent.

10. A nutritional supplement, a pharmaceutical, a tablet, a capsule, a softgel, a granule, a food confectionary form or a seed comprising a substrate coated with a film coating comprising the film coating composition of claim 1.

11. The film coating composition of claim 1 comprising a polyol.

12. The film coating composition of claim 11, wherein the polyol comprises xylitol.

13. The film coating composition of claim 1, wherein the plasticizing agent comprises glycerin, medium chain triglycerides, propylene glycol dicaprylate/dicaprate, polyethylene glycol, stearic acid, triethylcitrate, or a combination thereof.
