Abstract

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.

Dependent claims

An aerosol product comprising in combination a lined steel can and an aqueous compressed gas aerosol composition arranged and adapted to inhibit corrosion within the lined steel can and maintain stability of scent character of a fragrance component present in said aerosol composition, and to maintain stability of color of said composition wherein

(a) said lined steel can includes an aerosol dispensing top, body and base, and 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) the aerosol composition comprises
(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 the fragrance component,
(iv) pH adjuster component in an amount sufficient to provide said composition with an alkaline 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. %,
(vi) about 0.5 to about 2 wt. % of at least one nonionic surfactant and, optionally, up to about 3 wt. % of 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.

11 more elements

(B) said product comprising
(1) about 0.5 to about 2 wt. % of nonionic surfactant,
(2) 0 to about 3 wt. % of cationic surfactant,
(3) about 0.1 to about 2 wt. % of a fragrance component,
(4) about 0.5 to about 2 wt. % of compressed gas propellant,
(5) pH adjuster in an amount to achieve an alkaline pH of about 8 to less than 10 for the product,
(6) about 0.01 to about 0.5 wt. % of corrosion inhibitor,
(7) about 80 to less than 100 wt. % water;
(8) optionally a solvent selected from a group consisting of alcohols and glycols;
(9) optionally a buffer component;
and
(10) optionally a preservative component;
wherein components (1) to (10) of the product are present in amounts which in combination with the lining in the steel container provide said stabilized aerosol system;
and
wherein anionic, amphoteric and zwitterionic surfactants are excluded from the system.
