SPRAYABL~ POLIS~
Description Technical Field The present inv~ntion relates to aqueous, silicone-containing polish compositions, and . particularly to an aqueous~ silicone- and polishing clay-containing composition that can be applied to its substrate by spraying.
Background Art Aqueous compositions containing silicone polymers have provided a substantial improvement in the polishing arts, particularly for the preparation '~~ of water-resistant, hydrophobic coatings on hard surfaces such as the finish on an automobileO More ;~ 15 recent advances in the art have incorporated an -- amino-functional silicone polymer into the composition to provide improved resistance to detergents.
U.S. Patent No. 3,814,710 discloses a polishing composition which contains an ~-- amino-alkoxysiloxane that is present along with a conventional wax, solvent and optional ingredients including a thickening agent, a finely divided - abrasive; an emulsifying agent and water. In U.S.
-~ 25 Patent No. 3,960,5~5, a detergent-resis~ant polish is - said to be formed by the interaction o novel amino-functional silicone fluids. The polishes made ~~ - from those fluids are said to have improved rub-out and gloss by the addition of hydroxyl-terminated dialkylpolysiloxanes and/or silicone resins.
- A precursor polymer that is said to be ~"
~ useful in polish compositions is disclosed in ~.S~
Patent No. 3,890,271. In that patent, a mixture of hydroxyl endblocked dimethylpolysiloxane, an amino-functional siloxane and an alkoxy~ or acyloxy-functional silane are admixed in particular proportions. Polish compositions are then prepared from the precursor polymer, to which are added emulsifying agents, a hydrophobic clay abrasive, water and the like to form water-in-oil or oil-in-water emulsions which are said to provide useful water repellant polishes for automobiles.
In U.S. Patent No. 4,273,584, a detergent '~!resistant composition is said to be formed from another precursor polymer prepared from a hydroxyl~terminated silane which is admixed with a particular, amine group-containing polysilane that _is terminated with trialkoxysilane groups~ and optionally a partially hydrolyzed organo trialkoxysilane. The thus prepared composition may then be admixed with an emulsifier, solvent, abrasive and water to form a detergent-resistant car polish composition.
The above patents disclose the use of an -20 abrasive material such as silica, diatomaceous earth, or a hydrophobic clay, in an aqueous, silicone-containing composition. However, those :~compositions are too viscous and thus cannot be -sprayed by hand pump means cnto the substrate to be ~-25 polished because solid abrasive material-containing -compositions are formulated either as a paste whose viscosity is so high that the abrasive particles do not settle, or as a liquid in which settling ocurrs~ While in the latter compositions the soli~s portion is suffic;ently resuspendable to be applied by pouring, such compositions cannot be applied by spray means because resettling of the solid abrasive occurs too rapidly to deliver a substantially identical composition after several uses.
U.S. Patent No. 4,427,330 teaches an aqueous, silicone-containing emulsion which is said to be storage stable and suitable for sprayed dispensing in an automobile carwash. That patent combines an amino-functional silicone fluid and a cyclic siloxane, along with an aliphatic alcohol, an ~ acid present in sufficient quanity to neutralize the amine groups and an optional cationic emulsifying agent. The patent does not show or suggest the ~-- presence of a solid abrasive material.
However, it would be useful if a sprayable, ~- aqueous silicone~ and abrasive-containing polish ; composition could be prepared. The present invention provides such a composition that can be quickly and smoothly applied to give a shiny finish in a relatively short time period.
~ Summary of the Invention _ The present invention contemplates a polish compositon which contains an amino-functional silicone polymer and a finely-divided polishing clay dispersed in an aqueous medium. The composition is hand- or aerosol-sprayable for a quick application to a substrate to be polished. The composition consists essentiall~!T of an aqueous dispersion ..75 ~
~~ including at least about 70 weight percent water, about 0~5 to about 8 weight percent of a silicone fluid that includes an amino-functional - dialkylpolysiloxane as a major constituent, about 0.1 to about 2 weight percent of a self-emulsifying ~- wax, about 2 to about 20 weight percent of a ~ 30 polishing clay, and about 0.01 to about 10 weight j~'i7 percent of a dispersing agent. The p~ value of the _ composition is about 7.0 to about 8.3, preferably about 7.5 to about 8.1.
The amino-functional dialkylpolysiloxane 3S fluid can be derived from the equilibration of an dialkylpolysiloxane and an amino-functional silane or siloxane in the presence of a basic catalystO
The polish composition is sprayable by means of a hand-actuated spray pump device or an aerosol, bo~h of which impose similar sprayability requirements, and is substantially homogeneous when agitated by hand for a period of time less than about 5 minutes prior to spraying.
The composition may be used to polish a substrate such as an automobile finish by first ~ shak;ng the composition in a hand-actuated spray container. The shaken, sub~tantially homogeneous composition is then sprayed onto the substrate, ~-- either directly or first on to an applicator such as a clo~h. Thereafter, the applied composition is ~ wiped from the sub~trate with substantially no - rubbing, leaving a shiny finish~
The present invention has many benefits and advantages.
A particular advantage of the present ;- invention is that compositions embodying this invention are sprayable.
An additional advantage of the present ~; invention is that, nothwithstanding the relatively --: 25 high particulate solids content, these compositions may be sprayed by means of a hand-actuated pump or aerosol which provides a relatively small amount of - pressure as compared to a high pressure spray apparatus such as is availabl~ from a motor-powered sprayer~
A particular benefit of the present invention is that it provides a polish having exceptional performance in regard to the speed and smoothness of application, gloss and the durability of the applied polish.
Yet another benefit of the present invention is that the rubbing that is usually associated with polishing a substrate such as an automobile surface is not required~ The excess polish applied need only be wiped away to obtain a 5 high-gloss, detergent- resistant finish.
Still further benefits and advantages of the present invention will be apparent to those skilled in the art from the detailed description and examples which follow.
Detailed Desc~tion of the Invention Polish compositions of this invention may be applied to the surface of an automobile or another similarly hard surface to provide a shiny finish. In the following description and examples, ~ 15 an automobile surface will be utilized as an - exemplary substrate for the composition and method _ of this invention with the understanding the that use of the composition and method are not limited solely to automotive applications.
- 20 The composition of the present invention is ~ a dispersion of several component~ in water. Water is present in an amount of at least about 70 weight percent, and more preferably about 75 weight ,-~ percent, and provides a solids content of about 5 to -~ 25 about 25 weight percent. Preferbly, the non~volatile solids content of the compositions -- embodying the present invention is about 12 to about ~ 18 weight percent.
The polish composition contains about 0~5 to about 8 weight percent of a silicone fluid that includes an amino-functional dialkylpolysiloxane as a major constituent. More preferably, the composition contains about 1 to about 7 weight percent of the amino-functional dialkylpolysiloxane-containing silicone fluid.
The amino-functional dialkylpolysiloxane can be derived from the equilibration of a dialkylpo]ysiloxane having a viscosity of about 1 to about 30,00Q centistokes (cs.) at 25C. and an amino~functional silane or siloxane in the presence of a basic catalyst. The silicone ~luid may contain starting materials and reaction products in addition to the amino-functional dialkylpolysiloxane.
However, the alkyl substituents on the silicon atoms of the silicone fluid are substantially those of the dialkylpolysiloxane reactants.
A preferred dialkylpolysiloxane utilized in the preparation of the amino-functional dialkylpolysiloxane is a cyclic compound represented by the formula ~ SiO

Silicone fluids containing aminoalkyl dimethylpolysiloxanes that have primary and/or secondary amino groups are particularly preferred for the purposes of this invention. An illustrative, particularly preferred silicone fluid is that sold under the trademark SILICONE EMULSION E-184 by SWS
Silicones Corporation of Adrian, Michigan. SILICONE
EMULSION E-184 contains about 60 percent active silicone fluid emulsified in water. The active silicone fluid contains about 60 weight percent aminoalkyl dimethylsiloxane along with about 30 weight percent dimethylpolysiloxane having a viscosity o~
about 100 to about 30 9 000 CS . and about 10 weight percent of a cyclic volatile silicone having a viscosity of about 1 to about 10 cs.
The compositions of this invention include a polishing clay present at about 2 to about 20 weight percent, and more preferably at about 5 to about 15 weight percent of the composition. A hydrophilic polishing clay is preferred~ However, hydrophobic or oleophilic polishing clays can also be used, if desired~
It is preferred that the polishing clay present have a median particle size of about 0.1 to about 7 microns. Preferably, the median particle size is about 0.5 to about 5 microns, and most preferably about 0.5 to about 1 micron. ~i~h re~pect to particle size distribution, preferably 99.9% of the particles have a size below 10 microns and 91% of the particles have a size below about 2 microns.
The preferred hydrophilic polishing clay can be exempliied by the hydrophilic kaolin-derived material commercially available under the ~rade~arks KAOPOLITE SF and KAOPOLITE GG, sold by Kaopolite, Inc.
of Garwood, New Jersey. These hydrophilic polishing --ll--clays are compatible with amino-functional silicones and have the propertie~ listed in the table below~

The composi~ions of this invention also include about 0.1 to about 2 weigh~ percent, and more preferably about 0.2 to about 1 weight percent, of a self-emulsifying wax which can be processed in hot water to form a water-clear wax emulsion. Exemplary of such a self-emulsifying wax is a material commercially available under the ~rademark HOECHST
WAX VP~KST, sold by American Hoechst Corporation, Chemicals and Plastics D;vision, Somerville, New ~er~ey. This material is reported by its manufacturer to have a drop point of 122~158F.
(A.S.T.M. D 566/49~, an a~id number of 0-5 (A.S.T.M.
D 138/55/T), a saponiication number of 0-15 (A.S.T.M. D 1387/55/T~, and a density at 20 CO of 1.18-1.22 (A.S.T.M. D 70-27). This product is ~upplied as a light yellowish-colored powder and is an ester ~ormed between montan wax and a polyoxyethylene diol.
The composition of this invention is a sprayable dispersion and includes a dispersing agent which is preferably present at about 0.01 to about 10 weight percent of the total composition, and more preferably present at about 0.2 to about 5 weight percent.
A preferred dispersing agent includes a hydroxy functional silicone dispersed in a volatile silicone. The hydroxy-functional silicone is a polymer of dimethylsiloxane having side chains selected from the group consisting of polyoxyethylene, polyoxypropylene and mixtures thereof. The volatile silicone preferably is octamethyltetracyclosiloxane.
The CTFA names for these materials, listed in the CTFA Cosmetic In2redient Dictionary, 2 ed., 1972, published by The Cosmetic, Toiletry and Fragrance Association, Inc., are Dimethicone Copolyol and Cyclomethicone, respectively. The CTFA names will be utilized hereafter, fox convenience and uniformity.
The dispersion of dimethicone copolyol in cyclomethicone is commercially available under the traaemark Q2-3225C, sold by Dow Corning Corporation of Midland, ~ichigan. This dispersion preferably is utilized in an amount of about OoOOl to 8 weight percent of the composition and more preferably, at about 0.005 to about 3 weight percent. The dispersion contains dimethicone copolyol and cyclomethicone in a weight ratio of about 1:5 to about 1:15, respectively.
Another ingredient of the dispersing agent for the present composition is an aliphatic sulfonate having about 12 to about 18 carbon atoms in the aliphatic chain. A particularly useful material is that sold under the trademark TM HS 1 by ~merican Hoechst Corportion, of Somerville, ~ew Jersey. The aliphatic sulfonate is preferably utilized in an amount of about 0.001 to about 8.0 weight percent, and more preferably at about 0.005 to about 3 weight percent of the total composition.
The dispersing agent preferably also contains a colloidal montmorillonite clay having calcium and sodium ions as principal exchangeable cations. The montmorillonite clay is preferably utilized in an amount of about 0~005 to about 5 weight percent and more preferably at about 0.1 to ahout 2 weight percent of the total composition~
The montmorillonite clay should not induce a gel in the aqueous composition. A particularly useful montmorillonite clay whose aqueous compositions are substantially gel-free is that material sold under the trademark GELWHITE L by the Georgia Kaolin Company of Elizabethl New 3ersey. The montmorillonite clay acts principally to assist in retarding sedimentation of the polishing clay particles, but may also act to a small extent as an abrasive.
The compositions of this invention have a p~
value of about 7.0 to about 8.3. More preferably, the compositions have a p~ value of about 7.5 to about 8.1. ~he pH value of the composition as prepared from the above components is neutral to slightly basic, and is subsequently adjusted with a suitable acid, such as glacial acetic acid, to the desired value.
Maintenance of the pH value of the composition substantially within the above ranges is necessary to provide stability to the dispersion created. Thus, composition pH values below about 7.0 cause the emulsion to break down. Contrarily, when a composition pH value greater than about 3.3 is used, a cake forms which clogs the spray valve, and does not permit repeated dispensing of substantially the same composition on repeated product application.
Additional ingredients may also be included in the polish compositions of the present invention without departing or detracting from the essential characteristics of the composition. Exemplary additional ingredients include fragrance, colorant, an aliphatic organic solvent and a monohydric alcohol having 1 to about 3 carbon atoms, inclusive.
Thus, the composition of the present invention can additionally include about 0.1 to about 10 weight percent of an aliphatic organic solvent, and more preferably about 1 to about 5 weight percent. The solvent preferably has a boiling point of about 230~ to about 310 F., and more preferably a boiling point of about 250 to about 295 F.
Typically, the organic solvent is an aliphatic petroleum naphtha. The aliphatic organic solvent acts as a leveling or spreading agent for the polish composition.
The compositon of this invention can further include up to about 7 weight percent of a monohydric alcohol having 1-3 carbon atoms. Preferably, the alcohol content is about 1 to about 5 weight percent.
Exemplary of such alcohols are methanol, ethanol, iso-propanol, and mixtures thereof. The monohydric alcohol lends freeze-thaw stability to the polish composition.
The composition of the present invention may be made as follows. Approximately 15 to 25 percent of the water utilized in the composition is admixed with the self-emulsifying wax and anionic sulfonate dispersing agent. That admixture is heated with mixing to a temperature of about 180 to about 200 F. Once that elevated temperature is achieved, montmorillonite clay is added, and the resulting admixture is agitated at the elevated temperature for a period of about 30 minutes. Thereafter, about 10 to about 20 percent of the total water utilized in the composition is added to the heated resulting admixture, followed by a major portion of the monohydric alcohol and a major portion of the organic solvents when those components are used. The new resulting admixture is then agitated for about 15 to about 20 minutes or until it is substantially homogeneous. The temperature of the product ¢omposition is decreased to about 100 to about 110 F. The cooled composition is then transferred to a master mixing vessel. The silicone fluid containing the amino-functional dialkylpolysiloxane is thereafter added with admixing, followed by a preservative.
The remaining portion of the organic solvent i~ placed in a mixing container followed by the dispersion of dimethicone copolyol in cyclomethicone and the remainder of the monohydric alcohol. The admixture so produced is agitated until it is substantially homogeneous, and then it is added to the premixed components in the master mixing vessel.
A separate aliquot of about 20 to about 30 weight percent of the total water utilized in the composition is heated to a temperature of about 90 to about 100~ F. in a separate vessel which is equipped with an agitator. The particulate, polishing clay i5 added to the heated water and the resulting suspension is agitated for approximately 45 minutes. The particulate, polishing clay suspension ~6q~3~
is then added to the master mixing vessel and the resulting admixture is agitated until it is substantially homogeneous. The pH value of the composition is th~n adjusted to about 7.0 to about 8.3 using compatible acid such as acetic acid, or the like, and the remainder of the water ~hat is utilized is added to the composition. The composition so formed is agitated until substantially homogeneous, filtered to remove any undesirably large particles, and then packaged appropriately.
The dispersion so formed is an oil-in-water emulsion, although some of the dispersing agents, like the dispersion of dimethicone copolyol in cvclomethicone, are usually used for the preparation of water-in-oil emulsions.
The polishing clay particles may settle out from the dispersion on standing for a relatively long time period. However, the shaking of a closed container that is partially filled with the composition of this invention for a period of less than about S minutes, and more preferably less than a period of about 3 minutes, using only hand action, will readily resuspend the particulate polishing clay to form a substantially homogeneous composition that 2S can be sprayed through an orifice having a diameter of about 0.15 to about 0.25 micronsO This resuspendability and the maintenance of the suspended condition of the polishing clay particles for a period of time long enough for spray application of the polish composition of this invention are distinct advantages provided by this invention.
The particularly preferred method of spray application is by use of a hand-actuated spray means or pump. The term "hand-actuated" is used herein to mean that the spray means ejects the spray through the or if ice as a result of a force applied by the hand as through squee~ing or a downward force exerted on the spray pump.
The composition of this invention can also be applied using conventional aerosol spray technology, however. For example, the composition is placed into an aerosol can along with a suitable propellent such as a halocarbon~ e.g., fluorochloromethane, a rela-tively volatile hydrocarbon, e.g.~ propane iso-butane or a compressed gas such as carbon dioxide. A dip tube, stem and actuator are then affixed and the product is ready for u~e after suitable shaking.
The polish composition of this invention is utilized by first resuspending the particulate, preferably hydrophilic, polishing clay particles in the dispersion that may have settled out, as by shaking the container of the composition, to Eorm a substantially homogeneous composition. Thereafter, the substantially homogeneous composition is sprayed in excess upon the substrate sur~ace to be polished, such as an automobile finish, and spread over the surface of the finish, if necessary. After contact between the polish ~omposition and the surface of the substrate to be sprayed has been achieved, excess polish composition is removed, as by wiping.
No drying period is required to obtain the detergent resistant benefits of the polish of this invention, nor is a waiting time required for haze to form prior to removing the excess polish, nor is rubbing required to achieve the desired, 9105sy effect.
As used herein, the word "wiping" in its various grammatical forms is meant to indicate removal of the excess of applied poli~h composition without substantial pressure being exerted against the substrate to be polished. The word "rubbing~ in its various grammatical forms is used herein to indicate the exertion of a ~ubstantial pressure against the substrate to be polished in order ~o remove the excess polish composition and/or achieve a 5 high gloss when using prior art polishes.
In polishing an automobile~ it is preferred that the auto finish be clean and dry prior to the application of the polish of this invention.
The relative speed, ease and s~oothness with which the polish compositon of this invention can be applied to an automobile to obtain a superior, polished appearance is yet another of the salient benefits of this invention. Tests using a composition of this invention have shown that cars can be polished in an average time of less than about 15 minutes.
The present invention is further illustrated by the examples that follow.

In that patent, a mixture of hydroxyl endblocked dimethylpolysiloxane, an amino-functional siloxane and an alkoxy~ or acyloxy-functional silane are admixed in particular proportions. Polish compositions are then prepared from the precursor polymer, to which are added emulsifying agents, a hydrophobic clay abrasive, water and the like to form water-in-oil or oil-in-water emulsions which are said to provide useful water repellant polishes for automobiles.
In U.S. Patent No. 4,273,584, a detergent '~!resistant composition is said to be formed from another precursor polymer prepared from a hydroxyl~terminated silane which is admixed with a particular, amine group-containing polysilane that _is terminated with trialkoxysilane groups~ and optionally a partially hydrolyzed organo trialkoxysilane. The thus prepared composition may then be admixed with an emulsifier, solvent, abrasive and water to form a detergent-resistant car polish composition.
The above patents disclose the use of an -20 abrasive material such as silica, diatomaceous earth, or a hydrophobic clay, in an aqueous, silicone-containing composition. However, those :~compositions are too viscous and thus cannot be -sprayed by hand pump means cnto the substrate to be ~-25 polished because solid abrasive material-containing -compositions are formulated either as a paste whose viscosity is so high that the abrasive particles do not settle, or as a liquid in which settling ocurrs~ While in the latter compositions the soli~s portion is suffic;ently resuspendable to be applied by pouring, such compositions cannot be applied by spray means because resettling of the solid abrasive occurs too rapidly to deliver a substantially identical composition after several uses.

A particular benefit of the present invention is that it provides a polish having exceptional performance in regard to the speed and smoothness of application, gloss and the durability of the applied polish.
Yet another benefit of the present invention is that the rubbing that is usually associated with polishing a substrate such as an automobile surface is not required~ The excess polish applied need only be wiped away to obtain a 5 high-gloss, detergent- resistant finish.
Still further benefits and advantages of the present invention will be apparent to those skilled in the art from the detailed description and examples which follow.
Detailed Desc~tion of the Invention Polish compositions of this invention may be applied to the surface of an automobile or another similarly hard surface to provide a shiny finish. In the following description and examples, ~ 15 an automobile surface will be utilized as an - exemplary substrate for the composition and method _ of this invention with the understanding the that use of the composition and method are not limited solely to automotive applications.
- 20 The composition of the present invention is ~ a dispersion of several component~ in water.

Silicone fluids containing aminoalkyl dimethylpolysiloxanes that have primary and/or secondary amino groups are particularly preferred for the purposes of this invention. An illustrative, particularly preferred silicone fluid is that sold under the trademark SILICONE EMULSION E-184 by SWS
Silicones Corporation of Adrian, Michigan. SILICONE
EMULSION E-184 contains about 60 percent active silicone fluid emulsified in water. The active silicone fluid contains about 60 weight percent aminoalkyl dimethylsiloxane along with about 30 weight percent dimethylpolysiloxane having a viscosity o~
about 100 to about 30 9 000 CS . and about 10 weight percent of a cyclic volatile silicone having a viscosity of about 1 to about 10 cs.
The compositions of this invention include a polishing clay present at about 2 to about 20 weight percent, and more preferably at about 5 to about 15 weight percent of the composition. A hydrophilic polishing clay is preferred~ However, hydrophobic or oleophilic polishing clays can also be used, if desired~
It is preferred that the polishing clay present have a median particle size of about 0.1 to about 7 microns. Preferably, the median particle size is about 0.5 to about 5 microns, and most preferably about 0.5 to about 1 micron. ~i~h re~pect to particle size distribution, preferably 99.9% of the particles have a size below 10 microns and 91% of the particles have a size below about 2 microns.
The preferred hydrophilic polishing clay can be exempliied by the hydrophilic kaolin-derived material commercially available under the ~rade~arks KAOPOLITE SF and KAOPOLITE GG, sold by Kaopolite, Inc.
of Garwood, New Jersey. These hydrophilic polishing --ll--clays are compatible with amino-functional silicones and have the propertie~ listed in the table below~

The composi~ions of this invention also include about 0.1 to about 2 weigh~ percent, and more preferably about 0.2 to about 1 weight percent, of a self-emulsifying wax which can be processed in hot water to form a water-clear wax emulsion. Exemplary of such a self-emulsifying wax is a material commercially available under the ~rademark HOECHST
WAX VP~KST, sold by American Hoechst Corporation, Chemicals and Plastics D;vision, Somerville, New ~er~ey. This material is reported by its manufacturer to have a drop point of 122~158F.
(A.S.T.M. D 566/49~, an a~id number of 0-5 (A.S.T.M.
D 138/55/T), a saponiication number of 0-15 (A.S.T.M. D 1387/55/T~, and a density at 20 CO of 1.18-1.22 (A.S.T.M. D 70-27). This product is ~upplied as a light yellowish-colored powder and is an ester ~ormed between montan wax and a polyoxyethylene diol.
The composition of this invention is a sprayable dispersion and includes a dispersing agent which is preferably present at about 0.01 to about 10 weight percent of the total composition, and more preferably present at about 0.2 to about 5 weight percent.
A preferred dispersing agent includes a hydroxy functional silicone dispersed in a volatile silicone. The hydroxy-functional silicone is a polymer of dimethylsiloxane having side chains selected from the group consisting of polyoxyethylene, polyoxypropylene and mixtures thereof. The volatile silicone preferably is octamethyltetracyclosiloxane.
The CTFA names for these materials, listed in the CTFA Cosmetic In2redient Dictionary, 2 ed., 1972, published by The Cosmetic, Toiletry and Fragrance Association, Inc., are Dimethicone Copolyol and Cyclomethicone, respectively. The CTFA names will be utilized hereafter, fox convenience and uniformity.
The dispersion of dimethicone copolyol in cyclomethicone is commercially available under the traaemark Q2-3225C, sold by Dow Corning Corporation of Midland, ~ichigan. This dispersion preferably is utilized in an amount of about OoOOl to 8 weight percent of the composition and more preferably, at about 0.005 to about 3 weight percent. The dispersion contains dimethicone copolyol and cyclomethicone in a weight ratio of about 1:5 to about 1:15, respectively.
Another ingredient of the dispersing agent for the present composition is an aliphatic sulfonate having about 12 to about 18 carbon atoms in the aliphatic chain. A particularly useful material is that sold under the trademark TM HS 1 by ~merican Hoechst Corportion, of Somerville, ~ew Jersey. The aliphatic sulfonate is preferably utilized in an amount of about 0.001 to about 8.0 weight percent, and more preferably at about 0.005 to about 3 weight percent of the total composition.
The dispersing agent preferably also contains a colloidal montmorillonite clay having calcium and sodium ions as principal exchangeable cations. The montmorillonite clay is preferably utilized in an amount of about 0~005 to about 5 weight percent and more preferably at about 0.1 to ahout 2 weight percent of the total composition~
The montmorillonite clay should not induce a gel in the aqueous composition. A particularly useful montmorillonite clay whose aqueous compositions are substantially gel-free is that material sold under the trademark GELWHITE L by the Georgia Kaolin Company of Elizabethl New 3ersey. The montmorillonite clay acts principally to assist in retarding sedimentation of the polishing clay particles, but may also act to a small extent as an abrasive.
The compositions of this invention have a p~
value of about 7.0 to about 8.3. More preferably, the compositions have a p~ value of about 7.5 to about 8.1. ~he pH value of the composition as prepared from the above components is neutral to slightly basic, and is subsequently adjusted with a suitable acid, such as glacial acetic acid, to the desired value.
Maintenance of the pH value of the composition substantially within the above ranges is necessary to provide stability to the dispersion created. Thus, composition pH values below about 7.0 cause the emulsion to break down. Contrarily, when a composition pH value greater than about 3.3 is used, a cake forms which clogs the spray valve, and does not permit repeated dispensing of substantially the same composition on repeated product application.
Additional ingredients may also be included in the polish compositions of the present invention without departing or detracting from the essential characteristics of the composition. Exemplary additional ingredients include fragrance, colorant, an aliphatic organic solvent and a monohydric alcohol having 1 to about 3 carbon atoms, inclusive.
Thus, the composition of the present invention can additionally include about 0.1 to about 10 weight percent of an aliphatic organic solvent, and more preferably about 1 to about 5 weight percent. The solvent preferably has a boiling point of about 230~ to about 310 F., and more preferably a boiling point of about 250 to about 295 F.
Typically, the organic solvent is an aliphatic petroleum naphtha. The aliphatic organic solvent acts as a leveling or spreading agent for the polish composition.
The compositon of this invention can further include up to about 7 weight percent of a monohydric alcohol having 1-3 carbon atoms. Preferably, the alcohol content is about 1 to about 5 weight percent.
Exemplary of such alcohols are methanol, ethanol, iso-propanol, and mixtures thereof. The monohydric alcohol lends freeze-thaw stability to the polish composition.
The composition of the present invention may be made as follows. Approximately 15 to 25 percent of the water utilized in the composition is admixed with the self-emulsifying wax and anionic sulfonate dispersing agent. That admixture is heated with mixing to a temperature of about 180 to about 200 F. Once that elevated temperature is achieved, montmorillonite clay is added, and the resulting admixture is agitated at the elevated temperature for a period of about 30 minutes. Thereafter, about 10 to about 20 percent of the total water utilized in the composition is added to the heated resulting admixture, followed by a major portion of the monohydric alcohol and a major portion of the organic solvents when those components are used. The new resulting admixture is then agitated for about 15 to about 20 minutes or until it is substantially homogeneous. The temperature of the product ¢omposition is decreased to about 100 to about 110 F. The cooled composition is then transferred to a master mixing vessel. The silicone fluid containing the amino-functional dialkylpolysiloxane is thereafter added with admixing, followed by a preservative.
The remaining portion of the organic solvent i~ placed in a mixing container followed by the dispersion of dimethicone copolyol in cyclomethicone and the remainder of the monohydric alcohol. The admixture so produced is agitated until it is substantially homogeneous, and then it is added to the premixed components in the master mixing vessel.
A separate aliquot of about 20 to about 30 weight percent of the total water utilized in the composition is heated to a temperature of about 90 to about 100~ F. in a separate vessel which is equipped with an agitator. The particulate, polishing clay i5 added to the heated water and the resulting suspension is agitated for approximately 45 minutes. The particulate, polishing clay suspension ~6q~3~
is then added to the master mixing vessel and the resulting admixture is agitated until it is substantially homogeneous. The pH value of the composition is th~n adjusted to about 7.0 to about 8.3 using compatible acid such as acetic acid, or the like, and the remainder of the water ~hat is utilized is added to the composition. The composition so formed is agitated until substantially homogeneous, filtered to remove any undesirably large particles, and then packaged appropriately.
The dispersion so formed is an oil-in-water emulsion, although some of the dispersing agents, like the dispersion of dimethicone copolyol in cvclomethicone, are usually used for the preparation of water-in-oil emulsions.
The polishing clay particles may settle out from the dispersion on standing for a relatively long time period. However, the shaking of a closed container that is partially filled with the composition of this invention for a period of less than about S minutes, and more preferably less than a period of about 3 minutes, using only hand action, will readily resuspend the particulate polishing clay to form a substantially homogeneous composition that 2S can be sprayed through an orifice having a diameter of about 0.15 to about 0.25 micronsO This resuspendability and the maintenance of the suspended condition of the polishing clay particles for a period of time long enough for spray application of the polish composition of this invention are distinct advantages provided by this invention.
The particularly preferred method of spray application is by use of a hand-actuated spray means or pump. The term "hand-actuated" is used herein to mean that the spray means ejects the spray through the or if ice as a result of a force applied by the hand as through squee~ing or a downward force exerted on the spray pump.
The composition of this invention can also be applied using conventional aerosol spray technology, however. For example, the composition is placed into an aerosol can along with a suitable propellent such as a halocarbon~ e.g., fluorochloromethane, a rela-tively volatile hydrocarbon, e.g.~ propane iso-butane or a compressed gas such as carbon dioxide. A dip tube, stem and actuator are then affixed and the product is ready for u~e after suitable shaking.
The polish composition of this invention is utilized by first resuspending the particulate, preferably hydrophilic, polishing clay particles in the dispersion that may have settled out, as by shaking the container of the composition, to Eorm a substantially homogeneous composition. Thereafter, the substantially homogeneous composition is sprayed in excess upon the substrate sur~ace to be polished, such as an automobile finish, and spread over the surface of the finish, if necessary. After contact between the polish ~omposition and the surface of the substrate to be sprayed has been achieved, excess polish composition is removed, as by wiping.
No drying period is required to obtain the detergent resistant benefits of the polish of this invention, nor is a waiting time required for haze to form prior to removing the excess polish, nor is rubbing required to achieve the desired, 9105sy effect.
As used herein, the word "wiping" in its various grammatical forms is meant to indicate removal of the excess of applied poli~h composition without substantial pressure being exerted against the substrate to be polished. The word "rubbing~ in its various grammatical forms is used herein to indicate the exertion of a ~ubstantial pressure against the substrate to be polished in order ~o remove the excess polish composition and/or achieve a 5 high gloss when using prior art polishes.
In polishing an automobile~ it is preferred that the auto finish be clean and dry prior to the application of the polish of this invention.
The relative speed, ease and s~oothness with which the polish compositon of this invention can be applied to an automobile to obtain a superior, polished appearance is yet another of the salient benefits of this invention. Tests using a composition of this invention have shown that cars can be polished in an average time of less than about 15 minutes.
The present invention is further illustrated by the examples that follow.
