This invention is a composition comprising a cyclic siloxane, a silicone occlusive fluid, a silicone occlusive gel, and a silicone resin powder. The composition is useful for wound healing.

Claims (32)

1. A composition comprising:

a cyclic siloxane selected from the group consisting of cyclotetrasiloxane (octamethylcyclotetrasiloxane), cyclopentasiloxane (decamethylcyclopentasiloxane), cyclohexasiloxane (dodecamethylcyclohexasiloxane), and mixtures thereof;

a poly(dimethylsiloxane) having a viscosity between 100 cSt and 350 cSt;

a silicone gel in the form of a dispersion of a silicone elastomer in a silicone oil, wherein the silicone elastomer is selected from the group consisting of polysilicone-11, cetearyl dimethicone/vinyl dimethicone crosspolymer, dimethicone/phenyl vinyl dimethicone crosspolymer, dimethicone/vinyl dimethicone crosspolymer, and wherein the silicone oil is selected from the group consisting of phenyl trimethicone and phenyl dimethicone;

a polymethylsilsesquioxane powder; and

ascorbic acid tetraisopalmitate; and

wherein the concentration of the cyclic siloxane is between 55% and 65% by weight of the composition;

wherein the concentration of the poly(dimethylsiloxane) is between 3% and 7% by weight of the composition; and

wherein the concentration of the silicone gel is between 30% and 40% by weight of the composition.

2. The composition of claim 1 , wherein the poly(dimethylsiloxane) has a viscosity of 200 cSt.

3. The composition of claim 1 , wherein the cyclic siloxane is cyclopentasiloxane.

4. The composition of claim 3 , wherein the silicone elastomer is polysilicone-11 and the silicone oil is phenyl trimethicone.

5. The composition of claim 4 , wherein the poly(dimethylsiloxane) has a viscosity of 200 cSt.

6. The composition of claim 1 , wherein the concentration of ascorbic acid tetraisopalmitate is between 0.3% and 0.7% by weight of the composition.

7. A composition comprising:

cyclopentasiloxane;

a poly(dimethylsiloxane) having a viscosity between 100 cSt and 350 cSt;

a silicone gel in the form of a dispersion of a silicone elastomer in a silicone oil, wherein the silicone elastomer is polysilicone-11 and the silicone oil is phenyl trimethicone;

a polymethylsilsesquioxane powder; and

ascorbic acid tetraisopalmitate; and

wherein the concentration of cyclopentasiloxane is between 55% and 65% by weight of the composition;

wherein the concentration of the poly(dimethylsiloxane) is between 2% and 10% by weight of the composition;

wherein the concentration of the silicone gel is between 30% and 40% by weight of the composition; and

wherein the concentration of ascorbic acid tetraisopalmitate is between 0.1% and 2% by weight of the composition.

8. The composition of claim 7 , wherein the polymethylsilsesquioxane powder has an average particle size of 4-8micrometers.

9. The composition of claim 7 , wherein the concentration of the polymethylsilsesquioxane powder is between 1% and 5% by weight of the composition.

10. The composition of claim 8 , wherein the concentration of the polymethylsilsesquioxane powder is between 2% and 3% by weight of the composition.

11. The composition of claim 8 , wherein the concentration of the poly(dimethylsiloxane) is between 3% and 7% by weight of the composition.

12. The composition of claim 10 , wherein the concentration of the poly(dimethylsiloxane) is between 3% and 7% by weight of the composition.

13. The composition of claim 12 , wherein the poly(dimethylsiloxane) has a viscosity of 200 cSt.

14. The composition of claim 10 , wherein the concentration of ascorbic acid tetraisopalmitate is between 0.3% and 0.7% by weight of the composition.

15. The composition of claim 12 , wherein the concentration of ascorbic acid tetraisopalmitate is between 0.3% and 0.7% by weight of the composition.
