11. A system comprising:
a metallic container being made from a material selected from the group consisting of tin, aluminum, steel, and any combinations thereof; and
a composition having:
an active ingredient selected from the group consisting of a hair care active, a skin care active, a nail care active, a foot care active, a deodorant, an antiperspirant, a fragrance, an antimicrobial, an antifungal, an insect repellent, a sunscreen/UV absorber, and any combinations thereof;
water;
a cosmetically acceptable vehicle; and
a principle corrosion inhibiting agent in an amount effective to inhibit corrosion of the metallic container, wherein the principle corrosion inhibiting agent is a phosphate compound selected from the group consisting of disodium hydrogen phosphate, an alkali metal salt of a polyphosphate, and a combination thereof.
12. The system of claim 11 , wherein the container is an aerosol spray container, and wherein the composition further comprises a propellant.
13. The system of claim 11 , wherein the phosphate compound is the alkali metal or alkaline earth metal salt of a phosphate or a polyphosphate.
14. The system of claim 11 , wherein said phosphate compound is an alkali metal salt of a phosphate.
15. The system of claim 14 , wherein said alkali metal salt of a phosphate is disodium hydrogen phosphate.
16. The system of claim 11 , wherein said phosphate compound is an alkaline earth metal salt of a phosphate.
17. The system of claim 11 , wherein said phosphate compound is present in an amount about 0.05 wt % to about 1.5 wt % based on the total weight of the composition.
18. The system of claim 11 , wherein said phosphate compound is present in an amount about 0.1 wt % to about 1.0 wt % based on the total weight of the composition.
19. The system of claim 11 , wherein the composition further comprises volatile organic compounds in an amount not greater than about 85 wt % based on the total weight of the composition.
20. The system of claim 11 , wherein the composition further comprises volatile organic compounds in an amount not greater than about 55 wt % based on the total weight of the composition.
21. The system of claim 11 , wherein the container is made of aluminum.
22. The system of claim 11 , wherein the container is made from material having tin.
23. The system of claim 11 , wherein the container is made from a material having aluminum.
24. The system of claim 11 , wherein the container is made from a material having steel.
25. The system of claim 11 , wherein said phosphate compound is present in an amount about 0.1 wt % to about 0.5 wt % based on the total weight of the composition.
26. A topical composition comprising:
an active ingredient selected from the group consisting of a hair care active, a skin care active, a nail care active, a foot care active, a deodorant, an antiperspirant, a fragrance, an antimicrobial, an antifungal, an insect repellent, a sunscreen/UV absorber, and any combinations thereof;
