Solid film, rapidly dissolvable in liquids

摘要

A solid film rapidly dissolvable in liquids, in particular biological liquids, to release pharmaceutical, cosmetic and nutrient substances. The solid film is also soluble in biological organic liquids to protect wounds of the human body by releasing cicatrizing, disinfectant and cosmetic substances. The film can also be used to release flavoring substances directly onto moist nutrient products.

主权项

1. A solid film rapidly dissolvable in liquids and configured to have cicatizing filmogenic action for treating a small wound and/or an aphtha, comprising 25% and 60% of sodium alginate, 0.1% and 20% of microcrystalline cellulose, 0.1% and 25% of a vegetable protein, 5 to 12% polysorbate 60 or polysorbate 80, 15 to 45% of glycerin, sorbitol, or a combination thereof, the percentages being by weight on the weight of the finished solid film, and water, wherein the vegetable protein yields a water activity (Aw) of the solid film of between 0.1 and 0.3 and is the only preservation of the solid film and wherein the solid film is made by a process that comprises forming a film in a ventilated tunnel oven comprising four successive heating stations with a first heating station having a temperature of 60 to 80° C., a second heating station having a temperature of 70 to 90° C., a third heating station having a temperature of 70 to 90° C., and a fourth heating station having a temperature of 60 to 80° C.
