Description
D.N. 5331 CARPET CLEANING COMPOSITION
B~CKGROUND OF THE INV~NTION
(a) Filed of the Invention The invention relates to carpet cleaning compositions which impart to the carpet fibers oil repellent and antisoil S properties.
(b) Information Disclosure Statement Do-it-yourself carpet cleaning as opposed to profes-sional carpet cleaning has in the past enjoyed and still does enjoy considerable popularity. For this purpose, a wide variety of carpet cleaning and/or treating compositions have been made available or proposed. Such compositions generally incor-porate as the primary cleaning agent one or more detergents selected from ~oaps or diverse classes of surfactants and in many cases include one or more ingredients which function to impart to the carpet fibers beneficial properties such as antistatic, soil-, water-and oil-repellent properties.
See, for example, U.S. Patents 3,206,408; 3,639,290; 3,734,686;
3,736,2S9; 3,748,268; 3,775,052; 4,490,270 and 4,6S2,389. A
number of the foregoing references describe carpet cleaning and treating compositions which incorporate or may incorporate soil-retardants such as siliceous material, polystyrene, styrene copolymer, polymeric resins, colloidal alumina, carboxymethyl-cellulose, polyvinylpyrrolidone; vinyl acetate/maleic anhydride copolymers, carboxyl containing resins and melamineformaldehyde condensates.
A number of textile treating and carpet cleaning compositions have been proposed (see U.S. Patents 3,331,701;
D.N. 5331 3,372,~39; 3,733,281; 3,901,727; 4,043,923; 4,145,303 and 4,264,484) which include fluorinated compounds as soil retar-dants and/or agents for resisting wetting by water and/or oil or to impart some other beneficial property to the textile or carpet or to provide enhanced properties to the composition.
U.S. Patent 3,331,701 disclose~ the use of the reac-tion products of a cationic inorganic oxide with an aliphat-ic monocarboxylic acid of formula X(CF2)nCOOH wherein n is 3 to 20 to impart water, oil and soil repellency to textile fabrics and fibers. There is no teaching or suggestion in this reference that the disclosed flourinated aliphatic monocar-boxylic acids can be used as soil repellents in carpet cleaning compositions.
U.S. Patent 3,372,039 discloses the use of a colloidal suspension of a combination of a higher substantially fluorina-ted carboxylic acid and a zirconium oxyhalide to render textiles soil-, water- and oil-repellent. The fluorinated carboxylic acid has the formula [ZlCOOH wherein Z is a fluorocarbon radical having at least 3 carbon atom~ and preferably 7 to 17 carbon atoms wherein substantially all and preferably at least 70%
of the hydrogen atoms have been replaced by fluorine atoms.
U.S. Patent 3,733,281 discloses a cleaning liquid for carpets or fabrics which contains a fatty acid, an amine and a volatile fluorocarbon. The fluorocarbon, due to its rapid volatilization, functions to lift dirt to the surface of the carpet for easy removal by vacuuming and to provide for rapid drying of the carpet. The term fluorocarbons is D.N. 5331 1323819 `
i disclosed to mean fluoro- or chlorofluoro-methanes and ethanes.
U.S. Patents 3,901,727 and 4,145,303 diaclose an alkaline compos~tion effective for cleaning carpets, uphol~ter~
and the like which contains a detergent, an organic carboxyl-con-taining material, a Lewis ba8e, at least one zinc or zirconium coordination complex and a fluorochemical compound of the general formula ~Rf)a-X-(A)b where Rf is a fluorinated aliphatic radical of at least 3 carbon atoms, b is 1 or more, A is an acid group such as -COOH and X represents a variety of groups and any combination thereof. Included in the definition of X are S and (CH2)n where n is 1 or more. The fluorochemical compound in the form of a zinc or zirconium salt functions to impart water-and oil-repellency to the carpet or upholstery.
U.S. Patent 4,043,923 discloses the use of fluorochem-ical compounds to treat textiles such as carpets to impart $
thereto oil-and water-repellency and soil resistance. The fluoroahemical compound, which is dissolved or dispersed in a suitable liquid vehicle and which can be used in conjuncion with an anionic and/or nonionic detergent, is one in which a fluorinated aliphatic radical is linked to a carboxylic acid group through a non-fluorinated organic radical having at least 6 members, e.g. carbon atoms, in a skeletal backbone structure.
U.S. Patent 4,264,484 discloses that a carpet is rendered soil resistant and stain repellent by contacting D.N. 5331 13~3819 it with a composition compri~ing a liquid containing a certain water-insoluble addition polymer and a water-insoluble ester derived from a fluoroaliphatic radical- and aliphatic chlo-rine-containing alcohol and a mono-or polycarboxylic acid.
SUMMARY OF THE INVENTION
The invention resides in carpet cleaning compositions which impart excellent 80il and stain repellent properties to the carpet fibers.
Thus the invention provides an aqueous carpet cleaning composition comprising:
(a) from about 0.07 to about 1.8 percent by weight of a mixture of (i) a perfluoropropionate of formula I herein or mixture thereof and (ii) a perfluoroalkyl phosphate of formula II herein or mixture thereof, the weight ratio of (i) to (ii) being from about 1:1 to about 1:2;
(b) from about 0.05 to about 5.0 percent by weight of a nonionic, anionic or amphoteric surfactant or mixture thereof;
(c) 0 to an amount sufficient to provide a pH in the range of from about 4.0 to 9.5 of a pH adjusting agent;
and (d) water q.s. to 100%
D.N. 5331A
The composition of the invention in addition to cleaning spots, stains and ground-in dirt from a carpet, provides the carpet with excellent protection against resoiling. This protection is due to the stain and soil repellent mixture ' 5 of the fluorochemical compounds (i) and (ii) above which, during the cleaning procedure, penetrates the carpet and coats the carpet fibers thereby imparting thereto dirt and stain repellent properties. The composition of the' invention can also be used to clean and impart soil repellency to textile materials such"as home and auto uph`o'lstery.
DETAILED DESCRIPTION INC~VSIVE OF
- THE PREFERRED EMBODIMENTS
-~ The Fluorochemical ComPounds ' The primary anti-soiling and anti-staining agent is a mixture of ~-[2-[(2-carboxyethyl~thio]ethyl]-W'fluoro-poly-(difluoromethylene) lithium salt of the general formula F(CF2)n-CH2CH2-S-CH2CH2-COOLi(I), where n is 6 to 12, and the diethanolamine salt of a perfluoroalkyl phosphate represent-ed by the general formula:' ''' `' O
CF3CF2(CF2CF2)m-CH2CH2-0-PI=O mono/bis-diethanolamine salt o II
where m is 6 to 12.
The weight-ratio of the perfluoropropionate of formula I to the perfluoroalkyl phosphate of formula II in the mixture is in the range of from about 1:1 to about 1:2, and the amount 6 D.N. 5331A
of the mixture employed in the composition is from about 0.07 to about 1.8% by weight, preferably from about 0.1 to about 0.5~ by weight. Such mixture is manufactured by E.I. Du Pont de Nemours 6 Co., Inc. and sold under its trademark ZONYL
6885.
The Surfactant The composition of the invention contains a nonionic, anionic or amphoteric surfactant or mixture thereof to provide cleaning and emulsifying properties thereto. Such surfactants are commercially available and a wide variety thereof may be employed, the only limitation being that the particular surfactant chosen, when employed in concentrations according to the invention, does not leave a tacky or oily residue on the carpet fibers. The selection of a suitable surfactant or mixture of ~urfactants to be employed in the composition of the invention is well within the skill of one versed in the carpet cleaner art.
Examples of nonionic surface active agents are:
(a) the polyethylene oxide condensates of alkyl and dialkyl phenols, having a straight or branched alkyl of from about 6 to about 12 carbon atoms, with ethylene oxide wherein the amount of ethylene oxide present is from about 3 to about 25 moles per mole of alkyl and dialkyl phenol;
and the benzyl ether of such alkyl phenols.
(b) the condensation products of aliphatic alcohols with ethylene oxide of the formula RO(C2H4O)pH wherein R is straight or branched alkyl having from about 8 to about 22 carbon atoms and p is 3 to 40; and ~ 13238~9 _7_ D.N. 5331A
~c) th;e primary, monoethanol- and diethanolamides of saturated and unsaturated fatty acids having an alkyl moiety o from about 8 to 22 carbon atoms.
Examples of anionic surface active agents are:
~a) soaps such as alkali metal and amine, e.g., an ethanolamine, salts of higher saturAted and unsaturated fatty acids hav.ing from about 8 to about 24 carbon atoms;
(b) alkyl sulfonates and sulfates wherein the alkyl i8 straight or branched and has from about 8 to about 24 carbon n atoms and the cation is water-soluble, e.g., alkali metal and ammonium;
(c) sodium alkyl glyceryl ether sulfonates;
(d) alkyl ether sulfates of the formula R0(C2H40)~
S03Mlwherein R is alkyl or alkenyl having from about 10 to about 20 carbon atoms, q is 1 to 30 and Mlis a water-soluble cation, e.g., alkali metal and ammonium;
(e) alkali metal and amine, e.g. an ethanolamine, salts of mono- and di-alkyl esters of sulfosuccinic acid where alkyl can be fftraight or branched and has from 7 to 30 carbon atoms;
(f) alkali metal salts of alkylbenzene and alkyl toluene sulfonic acids where alkyl has from about 9 to about 15 carbon atoms; and (g) alkali metal and amine salts of alkyl alkoxy carboxylic acids of the general formula:
R-0(CrH2r)s-RlCOOM2 where R is a straight or branched alkyl having from 8 to 18 carbon atoms, r is 2 to 4, 9 iS 1 to 100; Rl is CH2, CH2CH2 i323819 8 D.N. 5331A
or CH2CH2C~l2; and M2is a sodium, potassium, lithium, ammonium, diethylammonium or triethylammonium cation or other cation, including multivalent cations.
Examples of amphoteric surfactants are the aminocar-boxylic and aminosulfonic acids and salts thereof such as alkali metal 3-(dodecylamino)propionate and alkali metal 3-~do-decylamino)propane-l-sulfonate; and alkyl and alkylamido betaines such as cocamidopropyl betaine.
It will be understood that the surfactants employed as cleaning and emulsifying agents in the compositions of the invention wi~ be materials o~her ~han the fluorochemical anti-soiling compounds described hereinabove which also have surfactant properties.
The amount of surfactant employed will generally fall in the range o from about 0.05 to about 5% by weight of the composition.
-The compositions of the invention may include optional ingredients for performing specifically desired functions such as sequestrants, e.g., citric acid, sodium hexametaphos-phate, tetrasodium ethylenediaminetetraacetate (Na4EDTA) and the like; organic liquid solvents for water-soluble stains, e.g., monohydric aliphatic alcohols having 1 to 6 carbon atoms such as ethyl alcohol, isopropyl alcohol and hexanol, glycols and glycol ethers such as 2-methoxyethanol, propylene glycol monomethyl ether, 2-butoxyethanol, 5-ethoxy-1-pentanol and the like; solvents for oily and greasy stains such as liquid aliphatic hydrocarbons and mixtures thereof such as mineral ~` ~
D.N. 5331 i323819 spirits (petroleum spirits) and hydrocarbons having from 5 to 19 carbon atoms, e.g., pentane, hexane, decane, tetradecane and nonadecane; preservatives quch as formaldehyde (formalin), methyl- and ethylparaben, 1,2-benzoisothiazol-3(2H)-ones, etc.; tracers for aerosol dispensed formulations as a visual indicator of where the composition has been applied to the carpet, e.g., cetyl alcohol; and corrosion inhibitors such as citric acid, sodium citrate, sodium nitrite, ammonia, etc.
The compositions of the invention are formulated as aqueous solutions or emulsions and can be dispensed for use as liquids using conventional dispensing devices such as squeeze bottles fitted with a suitable dispensing nozzle or containers fitted with trigger spray pumps; or as an aerosol from conventional aerosol containers fitted with a suitable dispensing valve and button.
When the aqueous composition is to be dispensed from an aerosol container, the container will contain, in addition to the aqueous composition, an aerosol propellant or mixture of propellants sufficient to provide adequate pres-sure to dispense the solution on each actuation of the aerosolvalve until substantially all of the composition eventually is exhausted. Propellants and propellant systems which can be employed are well known in the art. Typical of propellants which can be used are the low boiling chloro and fluoro substi-tuted alkanes and low boiling aliphatic hydrocarbons suchas propane/isobutane mixtures.
The pH of the aqueous composition of the invention should be in the range of from about 4.0 to 9.5. While good D.N. 5331 1~23819 carpet cleaning results are obtained throughout this pH range, the best results are obtained in the pH range of from about 4.0 to about 7.5 and therefore this pH range is generally preferred. However, when the aqueous composition is to be dispensed from an aerosol contalner of the type having tin-con-taining metallic components which will be exposed to the compo-sition, e.g., tin-containing metallic inner walls, the composi-tion should be in the alkaline pH range, i.e., from about 7.5 to 9.5, since an acid pH can have deleterious effects on such metallic components. However, compositions having a pH in the acidic range can be dispensed from aerosol containers having substantially no exposed inner metallic components such as those having metallic inner walls which are coated with plastic material.
If required, a pH adjusting agent is added to the composition in order to achieve a desired pH in the above-dis-closed pH range, for example, citric acid, ammonia, Na4EDTA
and the like. The choice of a particular pH adjusting agent is well within the skill of the art.
The composition of the invention can be prepared by adding the essential ingredients, i.e., the surfactant and the fluorochemical anti-soiling mixture, in any order to water with agitation followed by any optional ingredients in any sequence. Conveniently the surfactant is first added to most of the calculated amount of water required, followed by the fluorochemical mixture and then any optional ingredients.
The remainder of water is then added. When a pH adjuster is to be added, a sufficient amount thereof to achieve the i323819 22749-350 -11- D.N. 5331A
desired pH is added just prior to adding the remainder of the water.
Carpets are cleaned by applying the composition, e.g., by spraying, to approximately 3 square feet of the carpet at a time at a rate of about 5 g/sq. ft., allowing about 1 to 3 minutes for the composition to penetrate the treated area and then rubbing the area with a suitable device, e.g., a clean damp cloth or sponge mop, with rinsing of the cloth or mop as needed, until no soil appears on the cloth or mop.
n The cleaned area then is allowed to dry. Under normal condi-tions of temperature and humidity the cleaned area will be substantially dry in about 15 to 20 minutes. Drying time will vary in humid weather and on shag and deep pile rugs.
Vacuuming is not generally required. Optionally, when the composition is applied from an aerosol container, instead of mopping, cleaning may be completed by vacuuming the treated carpet after the carpet has dried.
The composition of the invention is illustrated by the following examples of specific formulations without, however, being limited thereto.

The compositions of Examples 1,2 and 3 were compared respectively with Compositions A,B and C for their ability to impart anti-soil properties to carpets. The procedures *Trademark -14- D.N. 5331A
employed con~isted of studies which included a trflfficking procedure wherein virgin beige cut pile carpet swatche~ tl' x 1') were placed in cut-out test areas of a basic carpet located in a high traffic area and people were funneled through S the test areas. The carpet swatches were treated prior to trafficking with individual compositions, as de~cribed below, and then instrumentally evaluated before and after soiling, i.e., after trafficking, by means of a Minolta Tri~timulus Colorimeter, Model No. CRllO, for color reflectance.
The te8t ~watches were sub~ected to 71,000 traffic steps, representing at least 1 year of normal household traffic soil~ along with untreated controls. The number of traffic steps was determined by means of an electronic counter placed under the carpet in the test area. The treating method employed was as follows. ~ach composition was appl~ed to a test carpet swatch at 5g/sq. ft. using a container fitted with a trigger spray pump set on the "spray" setting. The container in each case was shaken prior to use to en~ure complete emulsification of the composition. The composition was allowed to set on the carpet for 3 minutes and was then mopped 20 strokes in each direction using a damp standsrd sponge. Tbe test carpet swatch then was mopped again 10 strokes in eacb direction with a new moderately wet sponge. The test carpet swatch then was allowed to air dry.
The difference in color reflectance (~E) of the control (untreated) and treated carpet swatches before and after soiling (trafficking) in each case is given in Table *Trademark D.N. 5331 I wherein the lower the ~E, the better the anti-soiling effect.

The above results show the significantly superior soil retardent properties imparted to the carpets treated with the composition of Examples 1,2 and 3 compared to Composi-tions A,B and C.
A comparative study was conducted to determine if the presence of the anti-soiling fluorochemical mixture in the composition would impair the cleaning of a carpet. In this study the trafficking and cleaning procedures used and the method of measuring color reflectance were a8 described hereinbefore. The color reflectance of the virgin uncleaned carpet was measured, the carpet then wa~ trafficked (71,000 steps) and the carpet then was cleaned with the carpet cleaning composition. The carpet swatches employed had not been previous-ly treated for soil repellency by the manufacturer. The results are recorded in Table II wherein the lower ~E values reflect the carpet's appearance approaching that of the virgin carpet.

The composition of Example 4 and Composition C were compared in an oil repellency te~t wherein a 3" x 311 section of untreated carpet, i.e. not pre-treated with a soil, water or oil repellent by the manufacturer, was sprayed with l to 2 grams of the composition, using a container fitted with a trigger spray pump set on the spray position, and the carpet was allowed to dry. To the dry treated carpet section there was added from fln eye dropper l to 3 drops of used crankcase oil. The applied oil was observed for 60 seconds for penetra-tion, wetting and/or wicking into the carpet tufts and rated for oil repellent efficacy. The ratings used were:
(l) excellent/ oil beads on the surfaces for 60 seconds or more.
(2) good/ oil remains on the surface but wets the top after 30 seconds.

DETAILED DESCRIPTION INC~VSIVE OF
- THE PREFERRED EMBODIMENTS
-~ The Fluorochemical ComPounds ' The primary anti-soiling and anti-staining agent is a mixture of ~-[2-[(2-carboxyethyl~thio]ethyl]-W'fluoro-poly-(difluoromethylene) lithium salt of the general formula F(CF2)n-CH2CH2-S-CH2CH2-COOLi(I), where n is 6 to 12, and the diethanolamine salt of a perfluoroalkyl phosphate represent-ed by the general formula:' ''' `' O
CF3CF2(CF2CF2)m-CH2CH2-0-PI=O mono/bis-diethanolamine salt o II
where m is 6 to 12.
The weight-ratio of the perfluoropropionate of formula I to the perfluoroalkyl phosphate of formula II in the mixture is in the range of from about 1:1 to about 1:2, and the amount 6 D.N. 5331A
of the mixture employed in the composition is from about 0.07 to about 1.8% by weight, preferably from about 0.1 to about 0.5~ by weight. Such mixture is manufactured by E.I. Du Pont de Nemours 6 Co., Inc. and sold under its trademark ZONYL
6885.
The Surfactant The composition of the invention contains a nonionic, anionic or amphoteric surfactant or mixture thereof to provide cleaning and emulsifying properties thereto. Such surfactants are commercially available and a wide variety thereof may be employed, the only limitation being that the particular surfactant chosen, when employed in concentrations according to the invention, does not leave a tacky or oily residue on the carpet fibers. The selection of a suitable surfactant or mixture of ~urfactants to be employed in the composition of the invention is well within the skill of one versed in the carpet cleaner art.
Examples of nonionic surface active agents are:
(a) the polyethylene oxide condensates of alkyl and dialkyl phenols, having a straight or branched alkyl of from about 6 to about 12 carbon atoms, with ethylene oxide wherein the amount of ethylene oxide present is from about 3 to about 25 moles per mole of alkyl and dialkyl phenol;
and the benzyl ether of such alkyl phenols.
(b) the condensation products of aliphatic alcohols with ethylene oxide of the formula RO(C2H4O)pH wherein R is straight or branched alkyl having from about 8 to about 22 carbon atoms and p is 3 to 40; and ~ 13238~9 _7_ D.N. 5331A
~c) th;e primary, monoethanol- and diethanolamides of saturated and unsaturated fatty acids having an alkyl moiety o from about 8 to 22 carbon atoms.
Examples of anionic surface active agents are:
~a) soaps such as alkali metal and amine, e.g., an ethanolamine, salts of higher saturAted and unsaturated fatty acids hav.ing from about 8 to about 24 carbon atoms;
(b) alkyl sulfonates and sulfates wherein the alkyl i8 straight or branched and has from about 8 to about 24 carbon n atoms and the cation is water-soluble, e.g., alkali metal and ammonium;
(c) sodium alkyl glyceryl ether sulfonates;
(d) alkyl ether sulfates of the formula R0(C2H40)~
S03Mlwherein R is alkyl or alkenyl having from about 10 to about 20 carbon atoms, q is 1 to 30 and Mlis a water-soluble cation, e.g., alkali metal and ammonium;
(e) alkali metal and amine, e.g. an ethanolamine, salts of mono- and di-alkyl esters of sulfosuccinic acid where alkyl can be fftraight or branched and has from 7 to 30 carbon atoms;
(f) alkali metal salts of alkylbenzene and alkyl toluene sulfonic acids where alkyl has from about 9 to about 15 carbon atoms; and (g) alkali metal and amine salts of alkyl alkoxy carboxylic acids of the general formula:
R-0(CrH2r)s-RlCOOM2 where R is a straight or branched alkyl having from 8 to 18 carbon atoms, r is 2 to 4, 9 iS 1 to 100; Rl is CH2, CH2CH2 i323819 8 D.N. 5331A
or CH2CH2C~l2; and M2is a sodium, potassium, lithium, ammonium, diethylammonium or triethylammonium cation or other cation, including multivalent cations.
Examples of amphoteric surfactants are the aminocar-boxylic and aminosulfonic acids and salts thereof such as alkali metal 3-(dodecylamino)propionate and alkali metal 3-~do-decylamino)propane-l-sulfonate; and alkyl and alkylamido betaines such as cocamidopropyl betaine.
It will be understood that the surfactants employed as cleaning and emulsifying agents in the compositions of the invention wi~ be materials o~her ~han the fluorochemical anti-soiling compounds described hereinabove which also have surfactant properties.
The amount of surfactant employed will generally fall in the range o from about 0.05 to about 5% by weight of the composition.
-The compositions of the invention may include optional ingredients for performing specifically desired functions such as sequestrants, e.g., citric acid, sodium hexametaphos-phate, tetrasodium ethylenediaminetetraacetate (Na4EDTA) and the like; organic liquid solvents for water-soluble stains, e.g., monohydric aliphatic alcohols having 1 to 6 carbon atoms such as ethyl alcohol, isopropyl alcohol and hexanol, glycols and glycol ethers such as 2-methoxyethanol, propylene glycol monomethyl ether, 2-butoxyethanol, 5-ethoxy-1-pentanol and the like; solvents for oily and greasy stains such as liquid aliphatic hydrocarbons and mixtures thereof such as mineral ~` ~
D.N. 5331 i323819 spirits (petroleum spirits) and hydrocarbons having from 5 to 19 carbon atoms, e.g., pentane, hexane, decane, tetradecane and nonadecane; preservatives quch as formaldehyde (formalin), methyl- and ethylparaben, 1,2-benzoisothiazol-3(2H)-ones, etc.; tracers for aerosol dispensed formulations as a visual indicator of where the composition has been applied to the carpet, e.g., cetyl alcohol; and corrosion inhibitors such as citric acid, sodium citrate, sodium nitrite, ammonia, etc.
The compositions of the invention are formulated as aqueous solutions or emulsions and can be dispensed for use as liquids using conventional dispensing devices such as squeeze bottles fitted with a suitable dispensing nozzle or containers fitted with trigger spray pumps; or as an aerosol from conventional aerosol containers fitted with a suitable dispensing valve and button.
When the aqueous composition is to be dispensed from an aerosol container, the container will contain, in addition to the aqueous composition, an aerosol propellant or mixture of propellants sufficient to provide adequate pres-sure to dispense the solution on each actuation of the aerosolvalve until substantially all of the composition eventually is exhausted. Propellants and propellant systems which can be employed are well known in the art. Typical of propellants which can be used are the low boiling chloro and fluoro substi-tuted alkanes and low boiling aliphatic hydrocarbons suchas propane/isobutane mixtures.
The pH of the aqueous composition of the invention should be in the range of from about 4.0 to 9.5. While good D.N. 5331 1~23819 carpet cleaning results are obtained throughout this pH range, the best results are obtained in the pH range of from about 4.0 to about 7.5 and therefore this pH range is generally preferred. However, when the aqueous composition is to be dispensed from an aerosol contalner of the type having tin-con-taining metallic components which will be exposed to the compo-sition, e.g., tin-containing metallic inner walls, the composi-tion should be in the alkaline pH range, i.e., from about 7.5 to 9.5, since an acid pH can have deleterious effects on such metallic components. However, compositions having a pH in the acidic range can be dispensed from aerosol containers having substantially no exposed inner metallic components such as those having metallic inner walls which are coated with plastic material.
If required, a pH adjusting agent is added to the composition in order to achieve a desired pH in the above-dis-closed pH range, for example, citric acid, ammonia, Na4EDTA
and the like. The choice of a particular pH adjusting agent is well within the skill of the art.
The composition of the invention can be prepared by adding the essential ingredients, i.e., the surfactant and the fluorochemical anti-soiling mixture, in any order to water with agitation followed by any optional ingredients in any sequence. Conveniently the surfactant is first added to most of the calculated amount of water required, followed by the fluorochemical mixture and then any optional ingredients.
The remainder of water is then added. When a pH adjuster is to be added, a sufficient amount thereof to achieve the i323819 22749-350 -11- D.N. 5331A
desired pH is added just prior to adding the remainder of the water.
Carpets are cleaned by applying the composition, e.g., by spraying, to approximately 3 square feet of the carpet at a time at a rate of about 5 g/sq. ft., allowing about 1 to 3 minutes for the composition to penetrate the treated area and then rubbing the area with a suitable device, e.g., a clean damp cloth or sponge mop, with rinsing of the cloth or mop as needed, until no soil appears on the cloth or mop.
n The cleaned area then is allowed to dry. Under normal condi-tions of temperature and humidity the cleaned area will be substantially dry in about 15 to 20 minutes. Drying time will vary in humid weather and on shag and deep pile rugs.
Vacuuming is not generally required. Optionally, when the composition is applied from an aerosol container, instead of mopping, cleaning may be completed by vacuuming the treated carpet after the carpet has dried.

The compositions of Examples 1,2 and 3 were compared respectively with Compositions A,B and C for their ability to impart anti-soil properties to carpets. The procedures *Trademark -14- D.N. 5331A
employed con~isted of studies which included a trflfficking procedure wherein virgin beige cut pile carpet swatche~ tl' x 1') were placed in cut-out test areas of a basic carpet located in a high traffic area and people were funneled through S the test areas. The carpet swatches were treated prior to trafficking with individual compositions, as de~cribed below, and then instrumentally evaluated before and after soiling, i.e., after trafficking, by means of a Minolta Tri~timulus Colorimeter, Model No. CRllO, for color reflectance.
The te8t ~watches were sub~ected to 71,000 traffic steps, representing at least 1 year of normal household traffic soil~ along with untreated controls. The number of traffic steps was determined by means of an electronic counter placed under the carpet in the test area. The treating method employed was as follows. ~ach composition was appl~ed to a test carpet swatch at 5g/sq. ft. using a container fitted with a trigger spray pump set on the "spray" setting. The container in each case was shaken prior to use to en~ure complete emulsification of the composition. The composition was allowed to set on the carpet for 3 minutes and was then mopped 20 strokes in each direction using a damp standsrd sponge. Tbe test carpet swatch then was mopped again 10 strokes in eacb direction with a new moderately wet sponge. The test carpet swatch then was allowed to air dry.
The difference in color reflectance (~E) of the control (untreated) and treated carpet swatches before and after soiling (trafficking) in each case is given in Table *Trademark D.N. 5331 I wherein the lower the ~E, the better the anti-soiling effect.

A comparative study was conducted to determine if the presence of the anti-soiling fluorochemical mixture in the composition would impair the cleaning of a carpet. In this study the trafficking and cleaning procedures used and the method of measuring color reflectance were a8 described hereinbefore. The color reflectance of the virgin uncleaned carpet was measured, the carpet then wa~ trafficked (71,000 steps) and the carpet then was cleaned with the carpet cleaning composition.
