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.
Claims31
A film coating composition comprising
- a. a film forming agent selected from a cellulosic polymer,
- b. an opacifying agent comprising precipitated calcium carbonate at an amount of at least about 15% by weight,
- c. a complexing agent including a fatty acid, the complexing agent minimizing or preventing dissociation of the opacifying agent, and
- d. optionally, a second film forming agent selected from a cellulosic polymer.
A film coating composition comprising
- a. a film forming agent selected from a cellulosic polymer,
- b. an opacifying agent comprising precipitated calcium carbonate at an amount of at least about 15% by weight,
- c. a plasticizing agent,
- d. a complexing agent including at least one of a polyol and inulin, the complexing agent minimizing or preventing dissociation of the opacifying agent, wherein the polyol is selected from the group consisting of xylitol, maltitol, sorbitol, mannitol, erythritol, lactitol, and combinations thereof, and wherein the polyol, if present, is present in the composition in an amount from about 3% to about 25% of the composition by weight, and
- e. optionally, a second film forming agent selected from a cellulosic polymer.
A film coating composition comprising
- a. a film forming agent selected from a cellulosic polymer,
- b. an opacifying agent comprising precipitated calcium carbonate at an amount of at least about 15% by weight,
- c. a complexing agent minimizing or preventing dissociation of the opacifying agent, and,
- d. optionally, a second film forming agent selected from a cellulosic polymer,
- wherein a coating formed by applying the film coating composition to a substrate passes an immediate release disintegration test described in United States Pharmacopoeia 32/National Formulary 27, second supplement, chapter 2040 testing criteria or chapter 701 testing criteria.
