Definitions
- the present invention relates to aqueous aerosol foam cleaning compositions, particularly for use on carpets and upholstery.
- the invention is summarized as an aerosol foam-cleaning aqueous composition containing hydrocarbon propellant, foam-stabilizing polymer, surfactant, foam booster and a fluorinated stain-repellent, in which composition the proportions of the said components provide a foam of anti-flammability stability and sufficient residual amount of stain-repellent.
- Figs. 1-4 are graphs of flammability and oil repellency data from the tests described, below, in the Modes of Carrying out the Invention.
- Aerosol foam compositions for shampooing floor-coverings such as carpets or soft furnishings such as upholstery commonly comprise blends of surfactants and foam- stabilizer polymers, together with various other ingredients such as solvents, corrosion inhibitors and fragrances.
- the polymer stabilizes the foam produced and assists in the cleaning.
- a volatile hydrocarbon liquid propellant commonly is used to create a foam, the most commonly used propellant being butane.
- a typical foam cleaning aerosol composition might comprise an aqueous dispersion of acrylic/styrene copolymer; sodium lauryl sulfate; ammonia; preservative and perfume, all in water; and a propane/butane blend as propellant.
- Such a composition would possess the following advantages: (a) excellent pick-up;
- the foam resulting from these aerosols has a stability dependent on the combination of the properties of the components, such as the amount of surfactant and the nature of the polymer and the other foaming agents. This stability will also affect the rate of release of butane or other hydrocarbon from the foam structure. Since the hydrocarbons, particularly butane, are very inflammable, this rate of release can influence the flammability properties of the foam structure and particularly the risk of ignition if the foam is applied close to an ignition source. However, the permissible amounts and the relative ratios of the components can usually vary widely and still provide otherwise operable compositions.
- stain repellents materials treating the substrate material by forming a coating.
- stain-repellents include fluoro stain repellents, particularly oil repellent components that provide a stain-repellent finish to the material being treated with a foam cleaner, the finish remaining after cleaning is completed.
- Particular stain repellents are fluorocompounds such as fluoropolymers.
- Applicant's attempts to combine these fluorocompounds with aerosol foam cleaning compositions have resulted in foams that are unstable and that release hydrocarbon at an excessive rate, giving rise to flammability problems.
- non- volatile fluorocompound stain repellent compounds can be combined with the other components of a foam cleaning composition to provide a product that retains appropriate foam stability to provide a composition sufficiently non-flammable for use with improved safety even where there are potential ignition sources, such as open fires, cigarettes, and the like.
- These non-volatile fluorocompounds are added not as part of the propellant but as a part of the non- propellant portion of the cleaning composition. Fluorocompounds have been added to cleaning foams in the past, but those fluorocompounds were volatile compounds added as part of the propellant.
- an aerosol foam-cleaning aqueous composition containing hydrocarbon propellant, foam-stabilizer polymer, surfactant, foam booster and a fluorinated stain repellent in which the proportions of the said components provide a foam of anti-flammability stability and that leaves behind on the surface being cleaned an effective amount of stain repellent left as residual on the surface.
- Anti-flammability stability is defined here to mean that the rate of collapse of the foam does not release the hydrocarbon propellant at a rate that creates a flammability problem having regard to the standards established in the industry and described in detail in this patent.
- An "effective amount" of an ingredient is defined to be an amount sufficient to achieve the specified result or effect.
- An amount of stain repellent left as residual on a surface is deemed effective if it reduces the tendency of the surface to receive and retain visually apparent stains.
- the invention comprises an aerosol foam cleaning or shampoo formulation particularly for carpets or other soft furnishings, preferably comprising specified amounts of the particular components set out above.
- the particular composition relies on the presence of a volatile hydrocarbon liquid propellant, preferably butane, to create a foam on actuation. It is essential that the foam generated be sufficiently stable, and foam stability depends upon, inter alia, the amount and nature of surfactant utilized, the amount and nature of polymer utilized, the presence or absence of other foaming aids, and the amount of fluorocompounds present.
- the fluoro stain repellent compounds are added to such compositions to provide a post-cleaning, stain repellent finish and particularly an oil-repellent finish on the carpet, and can be fluoropolymer compounds or fluorosurfactant compounds.
- fluorocompounds in the foam has a marked influence on the surface tension thereof and therefore can greatly decrease the stability of the foam, which in turn leads to a marked increase in ignition potential. This is because, if the foam decreases in stability, then the level and rate of release therefrom of the volatile hydrocarbon propellant will increase. Since volatile hydrocarbon propellants are flammable, then their release above certain levels cannot be permitted in compositions of the type described herein without the production of unacceptable flammability.
- the amount of flammable volatile hydrocarbon propellant is carefully selected to be high enough that sufficient foam is generated but not so high that a flammable mixture is created.
- the composition must include sufficient fluorocompounds that an adequate level of post-cleaning stain repellency exists on the carpet after cleaning, while the composition remains sufficiently non-flammable.
- the precise amount of each component may have to be adjusted in a particular composition to achieve maximum cleaning activity and stability of foam.
- a number of materials can be utilized as the foam-stabilizer polymeric component of the foam cleaning compositions of the present invention, including the styrene maleic anhydride and related resins as disclosed in U.S. Pat. No. 3,835,071.
- resins as disclosed in U.S. Pat. Nos. 3,723,358 and 3,723,357 also can be used.
- acrylate copolymers and terpolymers such as methyl methacrylate-methacrylic acid copolymers and styrene- methyl methacrylate-methacrylic acid terpolymers.
- acrylic polymers are primary cleaning agents in these compositions and provide the function of soil entrapment when dry as well as some anti-resoil benefits.
- a preferred acrylic polymer for use in the invention is a copolymer of styrene and acrylic acids.
- a particular such acrylic polymer available commercially is JONCRYL 8660, which is provided as an aqueous emulsion of styrene and acrylic acid.
- This styrene acrylic acid copolymer is available as an aqueous dispersion containing from 20-30 weight percent resin, with the balance being water.
- the JONCRYL 8660 aqueous dispersion is an off-white, semi-translucent liquid. Since this acrylic polymer is commercially available as an aqueous emulsion, an appropriate adjustment has to be made in formulating the composition of the subject invention to allow for the presence of water. Thus, to provide a composition containing approximately 2 weight percent acrylic copolymer, JONCRYL 8660 dispersion would be added in an amount of 25 weight percent of composition.
- JONCRYL 8660 is available from S. C. Johnson & Son, Inc., of Racine, Wisconsin, and is also distributed by Specialty Chemicals Mijdrecht b.v., P.O. Box 259, 3640 AG Mijdrecht, The Netherlands.

- anionic organic detergents are alkyl glyceryl ether sulfonates, alkyl sulfonates, alkyl mono-glyceride sulfates or sulfonates, alkyl polyethoxy ether sulfonates, alkyl aryl sulfonates, acyl sarcosinates, acyl esters of isethionates, alkyl esters of sulfosuccinic acid, and alkyl phenol polyethoxy sulfonates.
- the alkyl and the acyl groups respectively contain 10 to 20 carbon atoms. They are used in the form of water-soluble salts, such as, by way of example only, sodium, potassium and ammonium salts.
- the anionic organic detergents include sodium lauryl sulfate, sodium dodecyl sulfonate and sodium N- lauroyl sarcosinate.
- nonionic organic detergents include polyethylene oxide condensates of alkyl phenols wherein the alkyl group contains from 6 to 12 carbon atoms and the ethylene oxide is present in a molar ratio of ethylene oxide to alkyl phenol in the range of 10 : 1 to 25 : 1 ; condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine wherein the molecular weight of the condensation products ranges from 5,000 to 11,000; the condensation product of from about 5 to 30 moles of ethylene oxide with one mole of a branched or straight-chain aliphatic alcohol containing from 8 to 18 carbon atoms; and trialkyl amine oxides and trialkyl phosphine oxides wherein one alkyl group ranges from 10 to 18 carbon atoms and two alkyl groups range from one to three carbon atoms.
- the preferred surfactants utilized in the present invention are anionic surfactants.
- a particular desirable surfactant blend is a mixture of sodium lauryl sulfate and di- sodium cocoamido sulfosuccinate. This particular surfactant blend is available from Rewo Chemicals Limited, Flimby Works, Maryport, Cumbria, CA15 8RP, England, under the trade name Rewopol TS 35.
- Rewopol TS 35 is provided in a dispersion of 35% in water to form a liquid. Since Rewopol TS 35 is provided as an aqueous preparation, appropriate adjustment has to be made to the composition to allow for the presence of water in the commercially available material.
- Suitable foam boosters can be any one of several commercially available amine oxides or mixtures thereof.
- a preferred amine oxide is of the formula CH 3 (CH 2 ) ⁇ oCH 2 -N(CH 3 ) 2 -_ ⁇ 0.
- other foam boosters can be employed.

- BARLOX 12 is cocodimethylamine oxide available as a 30% aqueous solution from Lonza Inc., 22-10 Route 208, Fair Lawn, New Jersey 08410, U.S.A.
- an appropriate adjustment would need to be made to take account of the fact that some of the materials available are provided as aqueous solutions.
- the fluoro stain repellent useful in the subject invention can be one of the fluoro materials known in the art to have this function and that is capable of being dispersed in the compositions. Such materials are generally fluoro polymers, optionally with surfactant groups, and are available as aqueous dispersions.
- the fluoro compounds useful in compositions made in accordance with the invention unlike the volatile and relatively low molecular weight stain repellent materials previously used as part of the propellant, are left on the substrate after the treatment. They are either fluorosurfactants or fluoropolymers or a mixture thereof. If the fluorocompound is a fluorosurfactant, then the amount of other surfactant required may be reducible by the amount of the fluorosurfactant present.
