## Abstract

An air treating composition for eliminating airborne malodors and/or sanitizing air in combination with a spray valve and actuator and spray performance parameters providing maximum dispersion of the composition is disclosed. The particles of the composition are small so that the active component is dispersed into air as a fine dispersion to provide more contact with malodors and to provide quick absorption of malodors and/or bacteria. The particle size of the composition is controlled through the valve and actuator dimensions, as well as the formulation requirements of the composition. The air treating composition includes water, a low molecular weight polyol, and a propellant. The composition may also include one or more adjuvants such as an emulsifier, a co-solvent, a fragrance, a corrosion inhibitor, a pH adjusting agent and the like.

## Claims

### Claim 1

An aerosol article for treating air comprising:
(1) a dispensing container including a spray head and (2) a composition for dispensing from said container, wherein said composition based on 100 wt. %, comprises
5 wt. % to about 25 wt. % of at least one polyol having a molecular weight of about 250 grams/mole or less;
from about 0.4 wt. % to about 4 wt. % emulsifier;
from about 10 wt. % to about 50 wt. % propellant;
from about 20 wt. % to about 90 wt. % water;
from 0 wt. % to about 60 wt. % co-solvent which is one or more of a low molecular weight monohydric alcohol or acetone; and
optionally, one or more components selected from the group consisting of fragrances, corrosion inhibitors, pH adjustors, antimicrobials, and preservatives;
wherein when said co-solvent is present in said composition in an amount sufficient to form an emulsion in absence of said emulsifier, said emulsifier can then be present in an amount of from 0 to about 4 wt. %; and
wherein said composition is a two-phase oil-out emulsion and said spray head is adapted so that upon said composition being dispensed from said spray head of said dispensing container, said composition has an average particle size of less than or equal to 45 μm over at least 75% of a life of said composition and a spray rate in a range from about 0.5 g/sec to about 2.5 g/sec over at least 75% of said life of said composition.

### Claim 2 (depends on 1)

The aerosol article for treating air according to claim 1, wherein the propellant is present in an amount of about 10 to about 35 wt. %.

### Claim 3 (depends on 1)

The aerosol article for treating air according to claim 1, wherein said emulsifier is a combination of sorbitan monooleate and a quaternary ammonium salt.

### Claim 4 (depends on 1)

The aerosol article for treating air according to claim 1, wherein a corrosion inhibitor is present and said corrosion inhibitor is potassium phosphate, sodium phosphate, potassium nitrite, sodium nitrite or mixtures thereof.

### Claim 5 (depends on 1)

The aerosol article for treating air according to claim 1, wherein the polyol is one or more of a monoalkylene glycol, dialkylene glycol, trialkylene glycol or glycerol.

### Claim 6 (depends on 1)

The aerosol article for treating air according to claim 1, wherein the composition has a pH in a range of about 8 to about 10.
