Coating composition comprising polydextrose, process for preparing same and use of coating ingestible solid forms
Composition (C) for coating ingestible solid forms, comprising, per 100% of its mass—from 10% to 90% of a graft copolymer of polyvinyl alcohol and of polyethers (Pi), and—from 10% to 90% by mass of an auxiliary coating agent, characterized in that a non-zero mass proportion of said auxiliary agent is polydextrose. Processes for the preparation and use thereof.
1. A film-coated solid form intended for gastric use and having a glossy appearance, the film formed by a coating composition (C) comprising, per 100% of its mass:
a) from 10% to 90% by mass of a grafted copolymer of polyvinyl alcohol and of polyethers (P 1 ); and
b) from 90% to 10% by mass of an auxiliary coating agent,
wherein a non-zero mass proportion of the auxiliary agent is polydextrose, and the ratio by mass of the grafted copolymer (P 1 ) to the polydextrose is less than or equal to 3, wherein the film-coating exhibits a gloss density of 1521 to 1707 and/or a degree of gloss of 0.77 to 0.80.
2. The film-coated solid form of claim 1 , wherein the coating composition (C) also comprises from 2% to 30% by mass of a plasticizer or of a mixture of plasticizers.
3. The film-coated solid form of claim 2 , wherein the coating composition (C) also comprises from 2% to 30% by mass of one or more coloring agents.
4. The film-coated solid form of claim 1 , wherein the coating composition (C) also comprises from 2% to 30% by mass of one or more coloring agents.
5. The film-coated solid form of claim 4 , wherein the coating composition (C) also comprises from 2% to 30% by mass of one or more inert fillers.
6. The film-coated solid form of claim 1 , wherein the coating composition (C) also comprises from 2% to 30% by mass of one or more inert fillers.
7. The film-coated solid form of claim 6 , wherein the coating composition (C) also comprises from 1% to 20% by mass of a glidant.
8. The film-coated solid form of claim 1 , wherein the coating composition (C) also comprises from 1% to 20% by mass of a glidant.
