Assignee:	NeurogesX, Inc. (San Mateo, CA)
Application Number:	12/830,997
Patent Claims:	1. A method for removing capsaicin from a bodily surface comprising: topically applying a surfactant-free gel composition to the bodily surface, the bodily surface having capsaicin thereon; wiping the surfactant-free composition off the bodily surface after the surfactant-free gel composition has been on the bodily surface for one minute, sufficient to solubilize at least 10% w/w of the capsaicin, wherein the surfactant-free gel composition comprises 80-90 percent w/w polyethylene glycol. 2. The method of claim 1, wherein the surfactant-free gel composition has a viscosity of between 4000 cps to 8000 cps. 3. The method of claim 2, wherein the surfactant-free gel composition has a viscosity of 5000 cps. 4. The method of claim 2, wherein the surfactant-free gel composition has a viscosity of 8000 cps. 5. The method of claim 1, wherein at least 20 percent w/w of the capsaicin is solubilized in the surfactant-free gel composition. 6. The method of claim 5, wherein at least 25 percent w/w of the capsaicin is solubilized in the surfactant-free gel composition. 7. The method of claim 1, wherein the surfactant-free, gel composition is impregnated in a porous substrate. 8. The method of claim 7, wherein the porous substrate is a towellette. 9. The method of claim 1, wherein the bodily surface is the skin, eyes, or a mucous membrane. 10. The method of claim 9, wherein the bodily surface is the skin. 11. The method of claim 1, wherein the capsaicin on the bodily surface is supplied by a capsaicin composition comprising 0.001 to 60 percent w/w capsaicin. 12. The method of claim 11, wherein the capsaicin composition is a patch. 13. The method of claim 11, wherein the composition is a lotion. 14. The method of claim 2, wherein the surfactant-free gel composition has a viscosity of 4000 cps.
