An aqueous compressed gas aerosol formulation in combination with a lined steel can, which may also optionally be tin plated, to provide corrosion stability, fragrance stability and color stability. An aerosol formulation of particular advantage for use is an air and/or fabric treatment formulation. The combination provides a compatibility which allows for the ability to use a broader fragrance pallet for the air and/or fabric treatment formulation which is aqueous based in major proportion. The formulation includes, in addition to an aqueous carrier, a fragrance, nonionic surfactant(s) or a blend of nonionic surfactant(s) and cationic surfactant(s), a compressed gas propellant(s), pH adjuster(s), and corrosion inhibitor(s). The formulation has a pH of about 8 to less than 10. The corrosion inhibitor(s) is(are) mild in strength and used in a minor amount. |

1. An aerosol product comprising in combination
(a) steel can with aerosol dispensing top, body and base, wherein said steel can has an interior surface having thereon a lining which is an organic coating or polymeric laminate, and, optionally a tin coating, wherein when the tin coating is present, the lining is provided over top of said tin coating; and (b) a composition consisting of
(i) water in an amount greater than about 80 wt. % but less than 100 wt. %,(ii) about 0.5 to about 2 wt. % of compressed gas propellant,(iii) about 0.1 to about 2 wt. % of fragrance component,(iv) pH adjuster component in an amount sufficient to provide said composition with a pH of about 8 to less than 10,(v) corrosion inhibitor component in an amount greater than 0, but equal to or less than about 0.5 wt. % comprising one or more of a phosphate, nitrite or silicate corrosion inhibiting compound,(vi) about 0.5 to about 2 wt. % of surfactant component which is either (1) at least one nonionic surfactant or (2) a blend of at least one nonionic surfactant and at least one cationic surfactant,(vii) optionally a solvent selected from a group consisting of alcohols and glycols,(viii) optionally a buffer component, and(ix) optionally a preservative component; wherein said composition is contained in said steel can and contacts said lining on said interior surface of said steel can; wherein said composition excludes anionic, amphoteric and zwitterionic surfactants, and wherein said corrosion inhibitor component, said fragrance component and said pH are selected so as to interact in a manner which maintains stable characters of corrosion inhibition, fragrance hedonics and formulation color. |
