DISSOLVABLE FILMS CONTAINING HIGH CONCENTRATIONS OF NON-IONIC SURFACTANTS SUCH AS POLYSORBATES TO ENHANCE HIGH SOLID LOADINGS Russian patent published in 2015 - IPC A61K8/02 A61K8/84 A61Q11/00 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to an oral care composition and method of making thereof. An oral care composition comprising a film in an amount of 0.1 wt % to 5.0 wt %, entrained in a carrier, wherein the film comprises a non-ionic surfactant polysorbate 80 in an amount from 10.5 wt % of the film to 20 wt % of the film and a solid calcium peroxide in the amount of 20% to 65% of the film weight. The film may further comprise a therapeutic active in the amount of 0.01 to 30 wt % of the film. The method of making an oral care composition being a dental care product, comprises as follows: (a) providing the carrier; (b) adding lamellar fragments of the film comprising polysorbate, in an amount of from 10.5 wt % of the film to 20 wt % of the film and a solid ingredient comprising calcium peroxide in an amount of from 20 wt % of the film to 65 wt % of the film; and (c) homogenizing the mixture, whereas the film is present in the amount of 0.1 wt % to 5.0 wt % of the of the total weigh of the composition.

EFFECT: higher active material loading in the film formula provides benefits, including reduced amount of film needed in a product, which is at the same time delivering improved efficacy with lower (0,1-5,0 wt %) loading of the film in the dental care composition.
