~ ~31~7~ ~3 The prior art is replete with hard surface cleansers containing abrasives both in the form of scouring powders and in liquid form. Water insoluble abrasives as the major and primary c:Leaning compo~ent in scouring powder cleansers is ~ell known, as disclosed in U.S. Patent No. 3J850~833.
However, the use of said water-insoluble abrasives in hard surface scouring powder cleansers has been found to lea~e an unpleasant gritty residue on the cleaned surface. This problem has been addressed in the prior art by substituting a water soluble abrasive for all or part of the insoluble abrasive, resulting in a composition wherein the water soluble components rinse away with the wash water, leaving substantially no residue on the I cleaned surface, as disclosed in U.S. Patent No. 3,577,347. Another method oE addressing the abrasive residue problem is the use of a powdered or particulate water-insoluble abrasive having a maxi = particle size under " 0.15 mm., and about 8~ by weight of the abrasive particle having a diameter of about 0.03/ mm or larger for eifective cleaning, and a small amount of an organic hydrotrope ~i.e. 9 sodium cumene sulfonzte~ to improve greas~
removal, as disclosed in U.S. Patent No. 4,2~9,640.
; Likewise, hard surface liquid detergent composition containing water-nsoluble abrasives suspended in an aqueous medium encounter th~ problems of stability as well as the difficulty of complete re~oval of the insoluble abrasive particles from the cleaned surface. These problems have beeD
addressed in the prior art by preparing a~heavy duty liquid detergent composition containing a ~ater soluble builder salt ha~ing colloidal-size I partlcles (below 1 mioron and usually below 0.1 ~icron), dispersed in an - aqueous medium containing a fat~y acid amide emulsifying agent as disclosed I in V.S. Patent No. 4,057~506. Other means of addressing the stability problem is disclosed in U.S. Patent No. 3,522,186 ~herein is disclosed a water-insoluble abrasi~e dispersed in an aqueous medium containing te~rapo~assium pyrophospha~, sodium soap, dietha~olamide and about 0.25-I.S~ meth}~o r ethanol to prevent the separation oE th; equeoos liqold Il ~

Another means of addressing the stability problem is disclosed in U.S. Patent No. 4,051,055 wherein an aqueous hard surface cleaning ~omposition ~ontaining water insoluble abrasive is suspended in a thickened aqueous medium with at least 17~ clay as the thickening agent, said thickened system preventing separation of the abrasive from the liquid medil~. The presence of fluoride salts enhances the ability of the clay-i, thickened systQm to hold the abrasive pirticles in suspension.
U.S. Patent No. 4,657,692 also discloses a thickened a~ueous scouring cleanser, free of syneresis (separation of solids from liquid), containing a Il uater insoluble abrasive suspended in an aqueous medium containing a ¦1I colloidal aluminu~ oxide thickener, water soluble al~ali metal inorganic ¦ll salts such as the phosphates, polyphosphates, carbonates, etc., and about ~0.5-3% of a surfactant and a halogen bleach. European Patent Application ¦¦¦ No. 0,193,375 resorts to the use of a water soluble salt, which functions ,I both as an abrasive and detergency builder, such as sodium bicarbonate, tripolyphosphate, and ~he like, in a pourable, homogenous abrasi~e-~containing aqueous detergent composition for cleaning hard surfaces3 and ;`i¦ also containing a mixture of anionic and nonionic surfactants in the weight~¦ratio of 1:1 to 9:1 anionic to nonionic surfactant.

Another organic solvent-based gelled or thickened hard s~rface cleaning composition ~, which is flowable and pour~ble is disclosed in U.S. Patent 3,~65,756 ,l comprising a gelling agent which functions as an abrasive such as colloidal silica, an alkaline builder salt such as water soluble phosphates and silicates, a surfactant, a wa~er insoluble abrasive, i.e., calcium silicate, and about 55-9~% of an organic cleaning solvent such as a major amount of an aliphatic hydrocarbon mineral spirit mixed with 4-7~ ethylene glycol monobutyl ether. U.S. Patent No. ~,8649770 also discloses a pourable non-aqueous water-soluble organic solvent-based thixotropic liquid detergent composition containing glycols and glycerol as the organic solvent, an ¦ anionic surfactant, and a phosphate builder i= suspension.
¦ However, none of the above mentioned patents disclose a hard surface non-pourable viscous cleaning composition, substantially free of water, comprising a gelled mixture of an organic liquid vehicle consisting ! I ~ essen~ially of water-soluble organic solvents and nonionic surfactants incl~ding an ethoxylated fatty acid as o=e vf the surfsctants, and a small I amount of sodium hydroxlde which reacts in situ with the etho~y}ated fatty ; ¦ aoid to form a clear organic, non-flowable gel, and about 10-25% of a water 1~ soluble builder-abrasive suspended in said gelled vehicle.

It has now been found that the formulation of present novel organic cltaning compo i ion i9 bas~d o= the abillty of etho~ylatecl iatty ~cid, J 1 ~ 7 !
i.e., ethoxylated lauric acid, to react with sodium hydroxide iQ organic media and form a gel with the media. Another feature of present novel formulation is the incorporation of a water-soluble abrasive material into the organic gelling mixture. This enables the preparation of viscous products containing inorganic solids suspended in a gelled organic vehicle.
, While this ab~asive is insoluble in the gelled vehicle, it becomes soluble ll upon dilution of the product with water. Cleaning with the undiluted 1~ product is aided by the mild abrasive action of the abrasive, i.e., sodium pyrophosphate. The entire product dissolves in water leaving no gritty residue on or around the cleaned surfsces. Furthermore, this abrasive becomes a "surfactant builder" when the product is used diluted. Household ¦¦ surfaces such as ceramic and formlca surfaces can be cleaned with present novel products in the absence or presence of water without scratching the l surface. This product, both undiluted and diluted, has significantly ¦ improved cleaning efficie~cy providad by the triple action oE the organic solvent, the nonionic detergent and the abrasive. In the diluted product, the abrasive dissolves in the water and becomes a detergency builder. The hard surface organic viscous product in accordance with this invention can function as a spray cleaner, a scouring cream and a floor a~d wall all purpose cleanser. Simulated floor cleaning tests show that at 3 g/l of 1~ i ~ present novel cleaning product pçrformed better than "Mr. Clean" at 15 g/l. /
this translates to 5 bottles of Mr. Clean being equal to 1 bottle of present cleaning product.
;~ hccordingly, ~he primary object of this invention is ~o provide a novel hard surface viscous organic cleaning product comprising an ethoxylated fatty acid and sodium hydroxide dissol~ed in an organic ~ehicle which react in situ to form a gelled vehicle.
; Another ob~ect of this invention is to provide a novel viscous organic cleaning co~position containing lnorganic water-soluble particulat~ abrasive suspen~ed in the gelled organic vehicle.

Still another object of ~his invention is to provide an abrasive-containing organic gel which dissolves in water leaving no gritty residue on or around the cleaned surfaces.
Still another object of this invention is to provide an all purpose organic cleanser having threefold cleansin~ action.
Additional objects, advantages and novel features of the invention ~ill be set forth in part in the description which follows, and in part will become apparent upon examination of the following specification or may be learned by practice of this invention.
To a~hieve the foregoing and other objects in accordance with the present invention as embodied and broadly described herein, the novel, stable, hard surface non-pourable organic cleaning gel composition of this invention comprises about 65-80Z by weight of an organic liquid vehicle coosistin~ essentially of about 15-35Z by weight of a water ~iscible organic solvent, about 35-70~ of a non~onic surfactant mixture containing an ethoxylated fatty acid as one of the surfactants, and a small amount of about 0.7-l.SZ by weight of sodium hydroxide, which reacts in situ with the ethoxylated fatty acid to form a clear5 nonflowable gelled vehicle, substantially free of water, capable of suspending water-soluble inorganic particulate abrasive.
More speci~ically7 the organic gel compositlon of present invention comprises about 65-80~ by wPight of a substantially water-free organic vehicle con~isting essentially of about 15-35X by wight of a water soluble organic solvent and about 35-70% by weight of a nonionic surfact3nt mi~tur~
containing an etho~ylated fatty acld as one oE the surfactants, about 0.7-1.5Z by ~eight of sodium hydroxide, gelled by the in situ reaction of the ethoxylated fa~ty acid with the sodium hydro~ide; and about 10-25% by ~eight of an inorganic water soluble particulate abrasive (builder salt~ uniformly suspended in the gelled veh~cle.
3L3~87~
The water miscible organic solvent is selected from the group consistiny of lower alkyl glycol ethers, lower alkyl monohydric alcohols, lower alkyl dihydric alcohols, and mixtures thereof.
The described hard surface cleaning products of present invention are stable, nsn-pourable, clear, thick ~viscous) pastes, having a minimum viscosity of about 14,000-15,000 cps units m~asured on Brookfield HATD viscometer. The viscosity of the gel product provides a stable suspension of relatively large particles of water-soluble abrasives i.e., larger than colloidal sized particles. The product of present invention has many applications as an all purpose cleaner.
Undiluted with water, the product can be used as a scouring cleaner for sinks and tubs, and as a spot cleaner for soiled hard surfaces, providing triple cleaning action due to the coaction of the organic solvent, the nonionic detergent and the abrasive, without leaving a gritty residue conventional with abrasive cleansers. Present novel organi~ pastes diluted with ; water can be used as a floor and wall cleaner. Present novel organic cleaning pastes can also be used as a waterless hand cleaner, particularl~ for mechanics and gardeners; for cleaning industrial and institutional cooking vessels, urns, etc.
~ p~TAIL~D D~SCRIPTION OF T~E INVENTION
: The major essential component of present nonpourable ~ viscous cleaning composition is the nonionic surfactant system ; ~ which constitutes about 35-70% by weight of a mixture of nonionic surfactants containing about 6-38% of an ethoxylated fatty acid, and about 10-64% of the other ethoxylated nonionic surfactants which may be a fatty alcohol, an alkyl phenol, a propylene oxide-propylene glycol condensation product or a mixture thereof. More speclfically, the additional ethoxylated ., ~ 7 ~3~7~
nonionic surfactant may be selected from the group consisting of a polyethylene oxide condensate of an alkyl phenol having an allcyl group containing about 6 to 22 carbon atoms, a polyethylene oxide condensate of an aliphatic a].cohol containing about 8 to 22 carbon atoms, a polyethylene oxide condensate of the condensation v~ 7a - 1 3 ~
i product of propylene oxide with propylene glycol having a molecular weight of about 1500 to 1800, and mixturPs thereof. Typical exampls of polyethylene oxide condensates of alkyl phenol are nonyl phenol condensed il with about 9.5 moles ethylene o~ide per mole nonyl phenol, dode~yl phenol condensed with about 12 moles of ethylene oxide per mole of phenol. Typical examples of ethoxylated alcohols include about 6 moles ethylene oxide condensed with one mole of tridecanol, myristyl alcohol condensed with about ,l 10 moles ethylene oxide, Cl~-C,4 fatty alcohol condensed with about 6 moles ;~l ethylene oxide) C~O_C,~ alcohol condensed with 5 moles ethylene oxide per il mole alcohol (Alfonic 1012-60). Examples of the polyethylene oxide condensates of the condensation product of propylene oxide with propylene ¦ glycol are com~ercially available as Pluronic surfactants marketed by the l~ Wyandotte Chemicals Corporation. The liquid character of this product is ,I retained up to the point where the polyoxyethylene content is about 50Z of the total weight of ~he condensation product. ~xamples of ethoxylated fatty acids include lauric, palmitic, stearic acid, etc., ethoxylated with about 5 to 10 ethylene oxides per mole fatty acid. A preferred fatty cid ethoxylate is laur~c acid having 9 ethylene oxides (Alkasurf-L-9). The presence of the ethoxylated fatty acid in the organic vehicle is essential in the formation of the gel, for ~he in situ reaction in the organic solvent with the sodium hydroxide to form a small amount of a soap which thickens and gels the organic liquid media. A small amount of sodium hydroxide svokes time-delayed hydrolysis followed by gela~ion of the ~ehicle holding the ethoxylated fatty acld.
~;~ ;Another essential component of present cleaning composition is the water miscible organic solvent in an amount of about 15-35% by weight of the total formulation. The organic solvent provides an organic medla for the in situ reaction between the ethoxyla~ed fatty acid and ~he sodium hydroxide in ~,the gelling of the organic ~edia. Suitable organic water mlscible solvents incl~de the lower alkyl monohydric alcohol, lower alkyl dihydric slcohols l ~ 7'R ~
; ~3~7~
. ~ .
(glycols), the ;ver alkyl glycol ethers, and mixtures thereof. ~xamples of water soluble lowe~ monohydric alcohols are ethanol, iso-propanol, and butanol. Examples of s~i~ahle glyols are ethylene glycol, diethylene glycol (Carbitol~, and propylene glycol. Exa~ples of lower alkyl glycol ethers are the diethylene glycol monobutyl etlher having the formula:
C~H~OCH~CHzocH~cH2o~ also known as Butyl Carbitol ~Union Carbide), ethylene glycol monobutyl ether having the formula: C~H90C~ZCH20~ and the like. It is preferred to use a mixture o-f ~onohydric and dihydric alcohols, and most preferably a mixture of a monohydric alcohol, a dihydric alcohol and a glycol ether as the solven~ for the nonionic surfactant mixture.
Another esse~tial ingredient in present viscous cleaning composition is a water-soluble inorganic particulate abrasive, suspended in the gelled vehicle, in an amount of about 10-25Z by weight of the total composition.
The abrasive is insoluble in the gel, but soluble in water. The water soluble abrasive particles are relatively large particles of about 1/2 m~ in diameter. The viscosity of the gelled vehicle which is a mini~um of l4,000 to 15,000 cps units, is capable of ~aintaining the large particles in suspension. Suitable water soluble abrasives are selected from the group consîsting of alkali metal phosphates, polyphosphates and carbonates.
Examples of suitable water soluble abrasives include pyrophosphates such as tetrasodium or tetrapotas5iu~ pyrophosphates, tripolyphosphates, tetrapolyphosphates~ carbonates, etc. This abrasiv~ beco~es a surfactant-builder when the product is used diluted and ie readily removed rom the cleaned surface, leaving no gritty residue. The preferred abras~ves include tetrasodium pyrophosphate, and sodium carbonate.
The hard surface cleaning composition of this invention also ~ay contain minor amounts of conventional additional component~ to impart any desired characteristic, which are compatible with the gel and do not adver9ely aEfect the ~el structure. Suitable additives in~lude coloring ~ ~3~7~; ) agents, pe~fl~es, preservatives, antiseptic agents and the like. These I additives constitute a maximum of 15% by weight of the composition.
The cleaning eo~positions of present invention are generally p~epared by mixing the orgænic water misci~le solvent componen~s with an ethoxylated fatty acid and at least one additional nonionic surfactant component to form a clear, low viscosity liquid vehicle; adding a sodium hydroxide solution to i I' the clear liquid vehicle and mixing until the liquid gels, which may vary 'I from a few minutes to several hours, depending on the amounts of the i1 components; and lastly admixing the water soluble abrasive, color, perfume and any other additional conventional ingredient with the gelled vehicle, ~1 until the abrasive is uniformly dispersed throu~hout the gelled vehicle and '~ a paste is formed. The cleaning composition is packaged in any suitable il container, both Elexible or rigid. The paste can also be e~truded from a I collapsible container.
,i The final cleaning gel product is a stable thick (viscou~) creamy, hard surface cleaner, substantially free of water, and has an alkaline p~ within il the range of about 8-11. It can be applied to ~he surface to be cleaned in any suitable manner, i.e., with a sponge or a cloth, followed by rinsing the ¦¦ surface with water,l leaving no gritty residue.
The -Eollowing examples merely illustrate the invention, but it is ¦ understood that the invet1tion is not limited thereto. All amounts of I various ingredients in the examples and elsewhere in the specification are by weight unless otherwlse specified.

It has now been found that the formulation of present novel organic cltaning compo i ion i9 bas~d o= the abillty of etho~ylatecl iatty ~cid, J 1 ~ 7 !
i.e., ethoxylated lauric acid, to react with sodium hydroxide iQ organic media and form a gel with the media. Another feature of present novel formulation is the incorporation of a water-soluble abrasive material into the organic gelling mixture. This enables the preparation of viscous products containing inorganic solids suspended in a gelled organic vehicle.
, While this ab~asive is insoluble in the gelled vehicle, it becomes soluble ll upon dilution of the product with water. Cleaning with the undiluted 1~ product is aided by the mild abrasive action of the abrasive, i.e., sodium pyrophosphate. The entire product dissolves in water leaving no gritty residue on or around the cleaned surfsces. Furthermore, this abrasive becomes a "surfactant builder" when the product is used diluted. Household ¦¦ surfaces such as ceramic and formlca surfaces can be cleaned with present novel products in the absence or presence of water without scratching the l surface. This product, both undiluted and diluted, has significantly ¦ improved cleaning efficie~cy providad by the triple action oE the organic solvent, the nonionic detergent and the abrasive. In the diluted product, the abrasive dissolves in the water and becomes a detergency builder. The hard surface organic viscous product in accordance with this invention can function as a spray cleaner, a scouring cream and a floor a~d wall all purpose cleanser. Simulated floor cleaning tests show that at 3 g/l of 1~ i ~ present novel cleaning product pçrformed better than "Mr. Clean" at 15 g/l. /
this translates to 5 bottles of Mr. Clean being equal to 1 bottle of present cleaning product.
;~ hccordingly, ~he primary object of this invention is ~o provide a novel hard surface viscous organic cleaning product comprising an ethoxylated fatty acid and sodium hydroxide dissol~ed in an organic ~ehicle which react in situ to form a gelled vehicle.
; Another ob~ect of this invention is to provide a novel viscous organic cleaning co~position containing lnorganic water-soluble particulat~ abrasive suspen~ed in the gelled organic vehicle.

Still another object of ~his invention is to provide an abrasive-containing organic gel which dissolves in water leaving no gritty residue on or around the cleaned surfaces.
Still another object of this invention is to provide an all purpose organic cleanser having threefold cleansin~ action.
Additional objects, advantages and novel features of the invention ~ill be set forth in part in the description which follows, and in part will become apparent upon examination of the following specification or may be learned by practice of this invention.
To a~hieve the foregoing and other objects in accordance with the present invention as embodied and broadly described herein, the novel, stable, hard surface non-pourable organic cleaning gel composition of this invention comprises about 65-80Z by weight of an organic liquid vehicle coosistin~ essentially of about 15-35Z by weight of a water ~iscible organic solvent, about 35-70~ of a non~onic surfactant mixture containing an ethoxylated fatty acid as one of the surfactants, and a small amount of about 0.7-l.SZ by weight of sodium hydroxide, which reacts in situ with the ethoxylated fatty acid to form a clear5 nonflowable gelled vehicle, substantially free of water, capable of suspending water-soluble inorganic particulate abrasive.
More speci~ically7 the organic gel compositlon of present invention comprises about 65-80~ by wPight of a substantially water-free organic vehicle con~isting essentially of about 15-35X by wight of a water soluble organic solvent and about 35-70% by weight of a nonionic surfact3nt mi~tur~
containing an etho~ylated fatty acld as one oE the surfactants, about 0.7-1.5Z by ~eight of sodium hydroxide, gelled by the in situ reaction of the ethoxylated fa~ty acid with the sodium hydro~ide; and about 10-25% by ~eight of an inorganic water soluble particulate abrasive (builder salt~ uniformly suspended in the gelled veh~cle.
3L3~87~
The water miscible organic solvent is selected from the group consistiny of lower alkyl glycol ethers, lower alkyl monohydric alcohols, lower alkyl dihydric alcohols, and mixtures thereof.
The described hard surface cleaning products of present invention are stable, nsn-pourable, clear, thick ~viscous) pastes, having a minimum viscosity of about 14,000-15,000 cps units m~asured on Brookfield HATD viscometer. The viscosity of the gel product provides a stable suspension of relatively large particles of water-soluble abrasives i.e., larger than colloidal sized particles. The product of present invention has many applications as an all purpose cleaner.
Undiluted with water, the product can be used as a scouring cleaner for sinks and tubs, and as a spot cleaner for soiled hard surfaces, providing triple cleaning action due to the coaction of the organic solvent, the nonionic detergent and the abrasive, without leaving a gritty residue conventional with abrasive cleansers. Present novel organi~ pastes diluted with ; water can be used as a floor and wall cleaner. Present novel organic cleaning pastes can also be used as a waterless hand cleaner, particularl~ for mechanics and gardeners; for cleaning industrial and institutional cooking vessels, urns, etc.
~ p~TAIL~D D~SCRIPTION OF T~E INVENTION
: The major essential component of present nonpourable ~ viscous cleaning composition is the nonionic surfactant system ; ~ which constitutes about 35-70% by weight of a mixture of nonionic surfactants containing about 6-38% of an ethoxylated fatty acid, and about 10-64% of the other ethoxylated nonionic surfactants which may be a fatty alcohol, an alkyl phenol, a propylene oxide-propylene glycol condensation product or a mixture thereof. More speclfically, the additional ethoxylated ., ~ 7 ~3~7~
nonionic surfactant may be selected from the group consisting of a polyethylene oxide condensate of an alkyl phenol having an allcyl group containing about 6 to 22 carbon atoms, a polyethylene oxide condensate of an aliphatic a].cohol containing about 8 to 22 carbon atoms, a polyethylene oxide condensate of the condensation v~ 7a - 1 3 ~
i product of propylene oxide with propylene glycol having a molecular weight of about 1500 to 1800, and mixturPs thereof. Typical exampls of polyethylene oxide condensates of alkyl phenol are nonyl phenol condensed il with about 9.5 moles ethylene o~ide per mole nonyl phenol, dode~yl phenol condensed with about 12 moles of ethylene oxide per mole of phenol. Typical examples of ethoxylated alcohols include about 6 moles ethylene oxide condensed with one mole of tridecanol, myristyl alcohol condensed with about ,l 10 moles ethylene oxide, Cl~-C,4 fatty alcohol condensed with about 6 moles ;~l ethylene oxide) C~O_C,~ alcohol condensed with 5 moles ethylene oxide per il mole alcohol (Alfonic 1012-60). Examples of the polyethylene oxide condensates of the condensation product of propylene oxide with propylene ¦ glycol are com~ercially available as Pluronic surfactants marketed by the l~ Wyandotte Chemicals Corporation. The liquid character of this product is ,I retained up to the point where the polyoxyethylene content is about 50Z of the total weight of ~he condensation product. ~xamples of ethoxylated fatty acids include lauric, palmitic, stearic acid, etc., ethoxylated with about 5 to 10 ethylene oxides per mole fatty acid. A preferred fatty cid ethoxylate is laur~c acid having 9 ethylene oxides (Alkasurf-L-9). The presence of the ethoxylated fatty acid in the organic vehicle is essential in the formation of the gel, for ~he in situ reaction in the organic solvent with the sodium hydroxide to form a small amount of a soap which thickens and gels the organic liquid media. A small amount of sodium hydroxide svokes time-delayed hydrolysis followed by gela~ion of the ~ehicle holding the ethoxylated fatty acld.
~;~ ;Another essential component of present cleaning composition is the water miscible organic solvent in an amount of about 15-35% by weight of the total formulation. The organic solvent provides an organic medla for the in situ reaction between the ethoxyla~ed fatty acid and ~he sodium hydroxide in ~,the gelling of the organic ~edia. Suitable organic water mlscible solvents incl~de the lower alkyl monohydric alcohol, lower alkyl dihydric slcohols l ~ 7'R ~
; ~3~7~
. ~ .
(glycols), the ;ver alkyl glycol ethers, and mixtures thereof. ~xamples of water soluble lowe~ monohydric alcohols are ethanol, iso-propanol, and butanol. Examples of s~i~ahle glyols are ethylene glycol, diethylene glycol (Carbitol~, and propylene glycol. Exa~ples of lower alkyl glycol ethers are the diethylene glycol monobutyl etlher having the formula:
C~H~OCH~CHzocH~cH2o~ also known as Butyl Carbitol ~Union Carbide), ethylene glycol monobutyl ether having the formula: C~H90C~ZCH20~ and the like. It is preferred to use a mixture o-f ~onohydric and dihydric alcohols, and most preferably a mixture of a monohydric alcohol, a dihydric alcohol and a glycol ether as the solven~ for the nonionic surfactant mixture.
Another esse~tial ingredient in present viscous cleaning composition is a water-soluble inorganic particulate abrasive, suspended in the gelled vehicle, in an amount of about 10-25Z by weight of the total composition.
The abrasive is insoluble in the gel, but soluble in water. The water soluble abrasive particles are relatively large particles of about 1/2 m~ in diameter. The viscosity of the gelled vehicle which is a mini~um of l4,000 to 15,000 cps units, is capable of ~aintaining the large particles in suspension. Suitable water soluble abrasives are selected from the group consîsting of alkali metal phosphates, polyphosphates and carbonates.
Examples of suitable water soluble abrasives include pyrophosphates such as tetrasodium or tetrapotas5iu~ pyrophosphates, tripolyphosphates, tetrapolyphosphates~ carbonates, etc. This abrasiv~ beco~es a surfactant-builder when the product is used diluted and ie readily removed rom the cleaned surface, leaving no gritty residue. The preferred abras~ves include tetrasodium pyrophosphate, and sodium carbonate.
The hard surface cleaning composition of this invention also ~ay contain minor amounts of conventional additional component~ to impart any desired characteristic, which are compatible with the gel and do not adver9ely aEfect the ~el structure. Suitable additives in~lude coloring ~ ~3~7~; ) agents, pe~fl~es, preservatives, antiseptic agents and the like. These I additives constitute a maximum of 15% by weight of the composition.
The cleaning eo~positions of present invention are generally p~epared by mixing the orgænic water misci~le solvent componen~s with an ethoxylated fatty acid and at least one additional nonionic surfactant component to form a clear, low viscosity liquid vehicle; adding a sodium hydroxide solution to i I' the clear liquid vehicle and mixing until the liquid gels, which may vary 'I from a few minutes to several hours, depending on the amounts of the i1 components; and lastly admixing the water soluble abrasive, color, perfume and any other additional conventional ingredient with the gelled vehicle, ~1 until the abrasive is uniformly dispersed throu~hout the gelled vehicle and '~ a paste is formed. The cleaning composition is packaged in any suitable il container, both Elexible or rigid. The paste can also be e~truded from a I collapsible container.
,i The final cleaning gel product is a stable thick (viscou~) creamy, hard surface cleaner, substantially free of water, and has an alkaline p~ within il the range of about 8-11. It can be applied to ~he surface to be cleaned in any suitable manner, i.e., with a sponge or a cloth, followed by rinsing the ¦¦ surface with water,l leaving no gritty residue.
The -Eollowing examples merely illustrate the invention, but it is ¦ understood that the invet1tion is not limited thereto. All amounts of I various ingredients in the examples and elsewhere in the specification are by weight unless otherwlse specified.
