Compositions and kits for the removal of irritating compounds from bodily surfaces
View Patent ↗The invention provides compositions, methods and kits for the removal of harmful or irritating substances from bodily surfaces. Kits may include a composition containing capsaicin and a capsaicin-cleansing composition, e.g., a composition in which capsaicin is soluble.
1. An aqueous composition for cleansing capsaicin from a bodily surface comprising:
a) about 80 to about 99 percent w/w polyethylene glycol (PEG); and
b) about 0.1 to about 4.0 percent w/w polyacrylate thickening agent,
wherein the aqueous composition has a viscosity of between 100 to 8000 cps.
2. The aqueous composition of claim 1 , comprising:
about 84 to about 94 percent w/w polyethylene glycol (PEG).
3. The aqueous composition of claim 2 , further comprising a stabilizer.
4. The aqueous composition of claim 3 , further comprising a cooling agent.
5. The aqueous composition of claim 3 , comprising:
a) about 87 to about 91 percent w/w polyethylene glycol (PEG);
b) about 0.3 to about 2 percent w/w polyacrylate thickening agent;
c) about 0.01 to about 0.03 percent w/w butylated hydroxyanisole;
d) about 0.02 to about 0.2 percent w/w edetate sodium; and
e) the balance water; wherein the aqueous composition is at a pH of about 7.0 to about 7.7.
6. The aqueous composition of claim 5 , comprising:
a) about 89.08 percent w/w PEG 300;
b) about 1.0 percent w/w polyacrylate thickening agent;
c) about 0.02 percent w/w butylated hydroxyanisole;
d) about 0.1 percent w/w disodium edetate; and
e) the balance water; wherein the aqueous composition is at a pH of about 7.5.
7. The aqueous composition of claim 1 , having a pH between about 7.0 and about 7.7.
8. The aqueous composition of claim 2 , comprising about 90 percent w/w polyethylene glycol (PEG).
9. The aqueous composition of claim 8 , further comprising:
i) about 0.1 to about 2.0 percent w/w polyacrylate thickening agent; and
ii) the balance water; wherein the aqueous composition is at a pH between about 7.0 and about 7.7.
10. The aqueous composition of claim 1 , wherein the PEG is PEG 200 to PEG 600.
11. The aqueous composition of claim 1 , in which capsaicin has a solubility of at least about 10 to 25 percent w/w.
12. The aqueous composition of claim 11 , in which capsaicin has a solubility of about 10 percent w/w.
13. The aqueous composition of claim 11 , in which capsaicin has a solubility of about 20 percent w/w.
14. The aqueous composition of claim 11 , in which capsaicin has a solubility of about 25 percent w/w.
15. The aqueous composition of claim 1 , which is a surfactant-free gel.
16. The aqueous composition of claim 1 , wherein the viscosity is between 4000 cps to 8000 cps.
17. The aqueous composition of claim 16 , wherein the viscosity is between 4000 to 5000 cps.
18. The aqueous composition of claim 1 , wherein the viscosity is between 2000 to 5000 cps.
19. The aqueous composition of claim 1 , wherein the viscosity is between 100 to 1000 cps.
20. The aqueous composition of claim 1 , which is substantially free of particulates.
21. The aqueous composition of claim 1 , wherein the polyacrylate thickening agent is an acrylic acid/ethylacrylate copolymer or a carboxyvinyl polymer.
