Abstract

A pharmaceutical, confectionery or food tablet coated on all its exterior surfaces with maltodextrin, which masks the characteristic taste of the tablet ingredients and does not have a slimy taste, with the coating composition comprising maltodextrin, an effective amount of a plasticizer to make the maltodextrin non-brittle and non-cracking when coated onto a tablet, an effective amount of a detackifier for making the maltodextrin and plasticizer non-tacky, a secondary film former to impart gloss and strength to the maltodextrin film coating, and a colorant for imparting color. A method of making tablets coated with maltodextrin.

Claims

1. A film modifier for adding to a primary film-former consisting essentially of powdered particles of film-forming non-toxic edible maltodextrin to make an edible film coating composition, the film modifier comprising

a dry mixture obtained by dry blending

a plasticizer suitable for making the maltodextrin non-brittle and non-cracking when coated onto a tablet, and

an effective amount of a detackifier suitable for making such plasticized maltodextrin non-sticky or non-tacky.

2. The film modifier of claim 1, including

an effective amount of secondary film former to impart gloss and strength to the maltodextrin film coating.

3. The film modifier of claim 1, including

a colorant for imparting color to the maltodextrin film coating.

4. The film modifier of claim 3, said colorant being titanium dioxide, FD&

C lakes, or D&

C lakes.

5. The film modifier of claim 3,

said colorant being titanium dioxide and a soluble dye.

6. The film modifier of claim 1,

the plasticizer being hydrogenated glucose syrup, polyethylene glycol 400, 3350, or 8000, triacetin, acetyltriethyl citrate, propylene glycol or glycerine.

7. The film modifier of claim 1,

the detackifier being modified derivatized starch, tapioca dextrin, polyethylene glycol 3350 or 8000.

8. The film modifier of claim 2, the secondary film former being propylene glycol alginate or sodium alginate.

9. A film modifier for adding to a primary film-former consisting essentially of powdered particles of film-forming non-toxic edible maltodextrin to make an edible film coating composition, the film modifier comprising

a dry mixture obtained by dry blending

a plasticizer suitable for making the maltodextrin non-brittle and non-cracking when coated onto a tablet, and

an effective amount of a detackifier suitable for making such plasticized maltodextrin non-sticky or non-tacky,

an effective amount of secondary film-former to impart gloss and strength to the maltodextrin film coating, and

a colorant for imparting color to the maltodextrin film coating,

said colorant being titanium dioxide, FD&

C lakes, or D&

C lakes,

the plasticizer being hydrogenated glucose syrup, polyethylene glycol 400, 3350, or 8000, triacetin, acetyltriethyl citrate, propylene glycol or glycerine,

the detackifier being modified derivatized starch, tapioca dextrin, polyethylene glycol 3350 or 8000, and

the second film former being propylene glycol alginate or sodium alginate.
