• it relates to biliquid foam dispersions in aerosol form.
• a wide variety of emulsions have been aerosolized by mixing them with gas propellants in an aerosol container. See generally U.S. Pat. Nos.
• emulsions can deliver furniture polishes, cleaning compounds, insecticidal or insect repellant compounds, herbicidal materials, cosmetic materials, or other desired surface treatment materials.
• an aerosol can may be charged with emulsified active and a propellant.
• the propellant is typically a hydrocarbon gas such as butane, propane, isobutane, isopropane, or mixtures thereof, or sometimes carbon dioxide.
• the active is sprayed from the can onto the surface to be treated.
• Substantial amounts of propellant are typically added, thereby altering the stability and/or uniformity characteristics of the emulsion.
• oil-in- water non-aerosol dispersions known as biliquid foams.
• the oil is present in discrete droplets surrounded by a first surfactant.
• the remaining water has dissolved in it a second surfactant.
• the second surfactant migrates to the surfactant-coated surface of the oil to create at least some drops (preferably most oil drops) surrounded by a bilayer of surfactant. See generally U.S. patents 4,486,333 and 6,312,760. See also F.

• a clothing rag is also a suitable type of rubbing cloth.
• the dispersion should include a thickener/viscosity modifier such as carbomers (such as a polymer of acrylic acid that has been cross-linked with a polyfunctional agent) , colloidal polymers, or gums at a very low concentration (between 0.05 and 2%; preferably between 0.05 and .5%; even more preferably between .05 and .3%).

• the most preferred thickener for a furniture polish is a salt of a cross-linked polymer of acrylic acid known as Carbopol ® Ultrez 5 (which is available from B.F. Goodrich). Specifically, it is a polymer of acrylic acid cross-linked with allylpentaerythritol .
• an antimicrobial agent to prevent bacterial growth during storage,, or to provide antibacterial effects to the surface being treated.

• additives conventional for those products e.g.
• aerosolized dispersions carrying actives (e.g. insecticidal; herbicidal; fragrances; deodorizers)
• actives e.g. insecticidal; herbicidal; fragrances; deodorizers
• standard aerosolized emulsions will be modified to reduce their surfactant content, provide the required thickener, and otherwise create the biliquid foam.
• nonionic surfactants appear to be useful for the purposes of the present invention.
• an alkanolamide for example an ester of an ethylene, diethylene or propylene glycol, or glycerol of a polyglycerol, or sorbitan, glucose or sucrose
• a polyoxyethylene or polyoxypropylene derivative of an alcohol, amide or ester or a polyoxyethylene/polyoxypropylene block copolymer, or a suitable compatible mixture thereof.
• the other surfactant can be selected from a wide variety of more polar surfactants.
• numerous other anionics should be suitable. Examples are acyl-lactate, N-acylsarcosinate, alkyl-carboxylate (either mono- or polyvalent) , alkyl ether carboxylate, N-alkyl-glutamate, fatty acid-peptide condensate, phosphated ethoxylated alcohol, alkyl sulphate, ethoxylated alkyl sulphate, alpha-olefin sulphonate and ester-linked sulphonate.
• the other surfactant may also be a cationic surfactant, an example of which is an amidoamine.
• the other surfactant might be an amphoteric such as acylaminoacid, an N-substituted alkylamine, an N-alkyl- ⁇ -aminopropionate, an N- alkylbetaine, an alkylimidazoline and a sulphobetaine.
• the preferred polysiloxanes are dimethylpolysiloxanes . However, other silicones can also be used. Preferred viscosity ranges are between 50 cts and 5,000 cts. Further, a wide variety of hydrocarbon oils should be suitable.
• a preferred mixture of a propellant gas and treating material for use in the present invention, in the form of a furniture polish, has the following formula:
• Klearol mineral oil is available from Witco Corp. and consists of saturated aliphatic and alicyclic non-polar hydrocarbons.
• the polysiloxanes can be obtained from a variety of different sources, such as Wacker Silicones or Dow Corning.
• Laureth-4 is a widely available nonionic surfactant (also known as polyethylene glycol ether of lauryl alcohol) .
• the dispersion In producing the dispersion, one first mixes the three oil components with the nonionic surfactant (Laureth-4). One then separately mixes the water, thickener, anionic surfactant (sodium lauryl ether sulphate), Kathon ® preservative and sodium hydroxide. At this point, one takes about 10 percent of the water phase and places it in a container. One then slowly drops the oil phase into the water phase while gently stirring at the top surface of the oil phase.
• the nonionic surfactant Laureth-4
• anionic surfactant sodium lauryl ether sulphate
• Kathon ® preservative sodium hydroxide
• the reason for this particular preferred method of formation of the biliquid foam is to provide the oil with the ability to be completely surrounded by the water phase in a properly ordered manner. This helps greatly in the formation of the biliquid foam.
• the container can have a conventional exit valve structure so that the mixture can be expelled from the aerosol container by pressing a button or the like.
• a preferred treating material in the form of an insecticidal control agent, for use in the present invention upon addition of a propellant gas has the following formula:
• This formula can be mixed in a manner analogous to that used for the furniture polish. Then, it can be placed in an aerosol dispenser can with pressurized gas in a manner analogous to that used for the furniture polish.
• a preferred treating material in the form of a hard surface cleaner, for use in the present invention upon addition of a propellant gas has the following formula :
• This formula can also be mixed in a manner analogous to that used for the furniture polish. Then, it can be placed in an aerosol dispenser can with pressurized gas in a manner analogous to that used for the furniture polish.
• formulations of the present invention do not need to have polar volatile cosolvents to achieve stability, even when polysiloxanes are present. This may have certain advantages in jurisdictions that are particularly environmentally conscious. It may also have advantages where the treating material is applied to certain sensitive surfaces.
• the mixture can be essentially free of organic solvents having a volatility of greater than 1 m/Hg at 25°C.
• the mixture can be essentially free of organic solvents having a volatility of greater than 1.3 mm/Hg at 25°C.
• the mixture can be alcohol free.
• the formulations may also contain other antimicrobial agents such as an ester of p-hydroxybenzoic acid, formalin or imidazolidinylurea.
• the furniture polish may be used in a manner similar to the way that aerosol furniture polishes such as Pledge ® brand polishes are currently used. In this regard, one takes the polish and sprays a desired amount (e.g. several ml of the polish) on a relatively small surface of furniture (e.g. a square meter) to be polished. The container will be held about six inches away from the surface to apply the polish.
• the polish is then spread and worked in by rubbing a cloth or other wipe over the surface (which desirably simultaneously acts to remove dust from the surface and place it on the rubbing cloth) .
• the surface may also be buffed if desired (as would be the case for a floor polish) .
• the spray can either be sprayed into the air, or at a target.
• the spray can be directed at the surface in a conventional manner.
• the biliquid foam polish formulations tested to date have provided surprising cleaning performance, as well as desirable gloss, wipeability, and visual aesthetic characteristics .
• the preferred embodiments have been described above, there are numerous other embodiments that are within the spirit and scope of the invention. Thus, the claims should be looked to in order to appreciate the full scope of the invention, and the claims are not to be construed to be limited to just the preferred embodiments.
• Industrial Applicability [0043] The invention provides aerosolized surface and air treating materials (e.g. polishes, cleaners and fragrancers) that are stored in the form of sprayable biliquid foams, and methods for their use.
