Abstract
Described herein are films comprising a particulate matter having a refractive index of from about 1.5 to about 2.0; a cellulosic material; and a polysaccharide; wherein the cellulosic material and the polysaccharide are present in a weight ratio of from about 2.2:1 to about 5:1; and wherein the film is substantially free of a titanium containing material. Compositions comprising same, and methods of using same are also described.

1-60. (canceled)
A film for use in an oral care composition, comprising:
- a polymer, a clay, a wax or a combination thereof;
- a natural gum;
- and
- a particulate having a refractive index of from about 1.0 to about 2.5;
- wherein the film is substantially free of titanium containing materials;
- and
- wherein the weight ratio of the polymer, clay, wax or combination thereof to the natural gum is from about 2.2:1 to about 5:1, and all weight percentages are based on the total weight of the film.
The film according to claim 1 comprising:
- from about 30 to about 70 wt. % of the polymer, the clay, the wax or the combination thereof;
- from about 5 to about 30 wt. % of the natural gum;
- wherein a weight ratio of the polymer, clay, wax or combination thereof to the natural gum is from about 2.5:1 to about 5:1;
- a particulate having a refractive index of from about 1 to about 2.5, the particulate selected from:
- stannic oxide;
- dicalcium phosphate;
- calcium carbonate;
- and a combination of two or more thereof;
- and
- optionally, an amount of menthol or a derivative thereof;
- wherein the film is substantially free of titanium dioxide, and all weight percentages are based on the total weight of the oral care film.
An oral care film comprising:
- from about 10 to about 50 wt. % of a polymer, a clay, a wax or a combination thereof;
- from about 5 to about 30 wt. % of a natural gum,
- wherein a weight ratio of the polymer, clay, wax or combination thereof to the natural gum is from about 2.2:1 to about 3.2:1;
- and
- a particulate having a refractive index of from about 1.0 to about 2.5, the particulate comprising calcium pyrophosphate;
- and
- optionally, an amount of menthol or a derivative thereof,
- wherein the film is substantially free of titanium dioxide, and all weight percentages are based on the total weight of the oral care film.
An oral care composition comprising:
- an orally acceptable carrier;
- and
- a plurality of films, or film fragments, wherein each film or film fragment comprises:
- a particulate matter having a refractive index of from about 1.5 to about 2.0;
- a cellulosic material;
- and
- a polysaccharide;
- wherein the cellulosic material and the polysaccharide are present in a weight ratio of from about 2.2:1 to about 5:1;
- and
- wherein the film is substantially free of a titanium containing material.
