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.

First claim

It is claimed:

1. Air and/or fabric treatment product comprising, in combination,
(1) an aqueous-based composition for treatment of air and/or fabric comprising
(a) greater than about 90 wt. % to about 99 wt. % water,
(b) about 0.5 to about 1 wt. % of at least one nonionic surfactant, including an alkylene oxide unit-containing nonionic surfactant,
(c) about 0.5 to about 1 wt. % of at least one compressed gas propellant,
(d) greater than 0 to about 6 wt. % of at least one non-water solvent,
(e) about 0.1 to about 0.5 wt. % of at least one corrosion inhibitor, said corrosion inhibitor being selected from the group consisting of phosphates, nitrites, silicates, amino methyl propanol, and mixtures thereof, and
(f) about 0.1 to about 2 wt. % of at least one fragrance,
wherein said composition is alkaline in pH and is single phase;
(2) a container comprising a sprayhead and a steel can wherein the steel can has an interior surface lined with at least a polymeric lining or an organic coating, said lining or said coating having a thickness of about 1 to about 12 microns; and

wherein said fragrance in said composition is maintained in said steel can stable against change in scent character and stable against degradation which results in discoloration of the composition;
wherein said composition excludes a liquefied petroleum gas (LPG) propellant; and
wherein anionic, amphoteric and zwitterionic surfactants are excluded from said composition.

2. The composition of claim 1 wherein said solvent is a glycol or an alcohol.

3. The composition of claim 1 wherein said nonionic surfactant is an alkoxylated hydrogenated castor oil compound.

4. The composition of claim 1 wherein said composition has a volatile organic content (VOC), excluding VOC of said fragrance, of 0 to about 6.

5. The composition of claim 1 further comprising a buffer.

6. The composition of claim 1 wherein said at least one compressed gas propellant is an inert non-oxygen-containing propellant.

7. The composition of claim 1 wherein said pH is about 8 to less than 10.

8. The composition of claim 1 further comprising a pH adjuster.

9. The composition of claim 1 further comprising a cationic surfactant.

10. Method of providing an air and/or fabric treatment product comprising
(1) providing a container including a sprayhead and a steel can, wherein the steel can has an interior surface with an organic coating or a polymeric lining thereon, said coating or said lining having a thickness of about 1 to about 12 microns; and
(2) providing in said steel can an aqueous-based air and/or fabric treating composition, wherein said composition comprises
(a) greater than about 90 wt. % to about 99 wt. % water,
(b) about 0.5 to about 1 wt. % of at least one nonionic surfactant, including an alkylene oxide unit-containing nonionic surfactant,
(c) about 0.5 to about 1 wt. % of at least one compressed gas propellant,
(d) greater than 0 to about 6 wt. % of at least one non-water solvent,
(e) about 0.1 to about 0.5 wt. % of at least one corrosion inhibitor, said corrosion inhibitor being selected from the group consisting of phosphates, nitrites, silicates, aminomethyl propanol, and mixtures thereof, and
(f) about 0.1 to about 2 wt. % of at least one fragrance,
wherein said composition is alkaline in pH and is a single phase;
wherein said composition excludes a liquefied petroleum (LPG) gas propellant; and
wherein anionic, amphoteric and zwitterionic surfactants are excluded from said composition; and

wherein said fragrance is maintained in said steel can stable against change in scent character and stable against degradation which results in discoloration of the composition; and wherein said composition is dispensable from said steel can via said sprayhead into air or over fabric or onto fabric to treat said air and said fabric.

11. The method of claim 10 wherein said solvent is a glycol or an alcohol.

12. The method of claim 10 wherein said nonionic surfactant is an alkoxylated hydrogenated castor oil compound.

13. The method of claim 10 wherein said composition has a volatile organic content (VOC), excluding VOC of said fragrance, of 0 to about 6.

14. The method of claim 10 wherein said composition further comprises a buffer.

15. The method of claim 10 wherein said at least one compressed gas propellant is an inert non-oxygen-containing propellant.

16. The method of claim 10 wherein said pH of the composition is about 8 to less than 10.

17. The method of claim 10 wherein said composition further comprises a pH adjuster.

18. The method of claim 10 wherein said composition further comprises a cationic surfactant.

19. Method of treating air and/or fabric comprising dispensing an aqueous-based air and/or fabric treating composition from a container, wherein said container includes
(1) a sprayhead and a steel can, the steel can having an interior surface with an organic coating or a polymeric lining thereon, said coating or said lining having a thickness of about 1 to about 12 microns; and
(2) said aqueous-based air and/or fabric treating composition in the steel can, wherein said composition comprises
(a) greater than about 90 wt. % to about 99 wt. % water,
(b) about 0.5 to about 1 wt. % of at least one nonionic surfactant, including an alkylene oxide unit-containing nonionic surfactant,
(c) about 0.5 to about 1 wt. % of at least one compressed gas propellant,
