Abstract
An edible, hardenable coating composition is disclosed which comprises high levels of low viscosity propylene glycol alginate and a surfactant, which may additionally contain a filler, a pigment and optionally a small amount of a secondary film former and/or a strengthening polymer. The coating composition of the present invention may be applied to pharmaceutical and veterinary solid dosage forms, confectionery, seeds, animal feed, fertilizers, pesticide tablets, and foods and provides an elegant prompt release coating which does not retard the release of active ingredients from the coated substrate.
Claims12
A solid dosage form coated with an edible, hardenable, prompt release coating composition comprising 55% to 85% of propylene glycol alginate and up to 10% of a surfactant, wherein the propylene glycol alginate is a primary film former of the composition and such that a 1% aqueous solution thereof has a viscosity in the range of about 1 to 500 mPa·s at 25° C.
An edible, hardenable, prompt release coating composition comprising:
- at least one of a filler and a pigment, the filler being maltodextrin;
- and
- 55% to 85% of propylene glycol alginate and up to 10% lecithin, wherein the propylene glycol alginate is a primary film former of the composition and such that a 1% aqueous solution thereof has a viscosity in the range of about 1 to 500 mPa·s at 25° C.
An edible, hardenable, prompt release coating composition comprising:
- at least one of a filler and a pigment, the pigment forming from 5% to 15% of the composition;
- and
- 55% to 85% of propylene glycol alginate and up to 10% lecithin, wherein the propylene glycol alginate is a primary film former of the composition and such that a 1% aqueous solution thereof has a viscosity in the range of about 1 to 500 mPa·s at 25° C.
An edible, hardenable, prompt release coating composition comprising 55% to 85% of propylene glycol alginate, 10% to 30% maltodextrin, and 2% to 10% lecithin, wherein the propylene glycol alginate is a primary film former of the composition and such that a 1% aqueous solution thereof has a viscosity in the range of about 1 to 500 mPa·s at 25° C.
An edible, hardenable, prompt release coating composition comprising 55% to 85% of propylene glycol alginate, 5% to 15% pigment, and 2% to 10% lecithin, wherein the propylene glycol alginate is a primary film former of the composition and such that a 1% aqueous solution thereof has a viscosity in the range of about 1 to 500 mPa·s at 25° C.
