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
1323819
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 `

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;

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.

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;

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
--10--
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.

by the following examples of specific formulations without,
however, being limited thereto.

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

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

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.
(3) fair/ oil wets top surface within 30 seconds.
