Backqround It is well-known to formula~e scouring compositions, in : ~iquid or creamy ~orm, containing solv~nts.
In p~r~cular, cr~my scouring compos~tlons co~taining an abrasive and 3 b~nary soluen~ sys~em cons~uted of terpenes i~nd polar soluents hau~ been disclosed in European Patent ~pplicat~on 0,126,5~5, published on Nouember ~8, 1984.~ In theso compositions, the terpenss show both~
.
~6~2(3 cleaning and desirable emulsification properties, which enhance product uiscosity.
It has become desirable, however, to replace terpenes by soluents which are fully compatible with ~ll types of surfaces to be cleansed therlewith, ~nd packaging materials, and at the same time exhibit good cleanlng and emulsification properties.
It has now been found that uiscous terpene soluent free creamy scouring cleanser compositions showing remarkable cleaning efficiency, ease-of-rinsing and surface-c~mpatibility, can be formulated which contain a narrowly-defined soluent deriued from propylene glycol.
US-3,591,510 discloses the use of soluents of this type in liquid hard surface cleaning compositions free of abrasiue. EP-~-0 040 8~2 mentions the use of propylene glycol-deriued soluents, in combination with terpenes and benzyl alcohols, in liquid hard surface cleaners free of abrasiue.
It is an object of the present inuention to prouide viscous creamy cleanser compositions which ~r~ fully compatible with surfaces to be cleansed therewith and p~c~aging materials. It is a further object of the present invention to prouide a cleanser composition with excellent cleaning, ease-o~-reasing and shin~ performance.
Summary of the Inuention The present inv~ntion relates to a ~iscous ereamy scouring cleanser being substantially ~ree of terpene soluents, containing a surface-acti~e agent, an abrasiue, ~)6~
-and ~n-orga~i~ soluent and if desired con~entional additi~es, characterized in that said cleanser is substantially free of terpene sol~ents and that the organic solvent is represented by the formula:
CH~
RO~CH2 HO)~H
wherein R is a Cl to C8 alkyl, alkenyl or alkyl aryl group, preferably a Cl to C4 alkyl group, and n is an integer from 1 to 4, preferably 1 or 2.
Detailed Description of the Inuention The surface-actiue agents, the abrasives, the solvent and the optional ingredients are described in more detail hereinafter.
Unless indicated to the contrary, the ~-indications stand for 1l~ by weight".
Surface-actiue ~qents Water-solubl2 detarsiue ~ur~act~nts useful herein includQ well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants and mixtures th~reof. Typical of these are the alkyl ben~ene sulfates and sulfonates, paraffln sulfonates, olefin sulfonates, alkoxylated (esjecially ethoxylated3 alcohols and alkyl phenols, amine oxides~ sulfonates of f~tty ~cids and o~ fatty acid esters, and the li.ke, which are well-known in the deter3ency art.
In general, such detersi~e surfactants contain an alkyl group in the C10-Cl~ range; ~he anionic ~e~ersi~e surfactants are most commonly used in the form of their sodium, potassium or triethanolammonlum salts. The nonionics generally contain from 3 to 17 ethylene o~ide groups per mole of hydrophobic moeity. Especially preferred in the compositions o~ the present invention are:
C12-C16 alkyl benzene sulfonates, C12-C18 paraffin-sulfonates and the ~2thoxylated alcohols of the formula RO(CH2CH20)n, with R being a C~2-C15 alkyl chain and n being a numbe~ from 6 to 10.
~ nionic surfactants are frequently present at leuels from 0.3 to B%, pre~erably 2 to 4X, of the composition.
Nonionic surfactants, are used at leuels between 0.1% to 6%
by weight of the composition. Mixtures of the like surfactants can also be used. The total level of surface-~ctiue agent is preferably from 3~ to 5~.
~brasiue - The abrasiue types employed henein are selected From water-insoluble, non-gritty materials ~ell-known in the literature for their relatluely mild abrasiue properties.
It is highly preferred that the abrasi~es used h~rein not be undesirably "scratchy". ~brasiue materials hauing a Mohs hardness in the range o~ abou~ 7, or below, are typically used; abrasiues havlng a ~ohs hardness of 3, or below, can be used to auoid scratches on ~luminum or stainless steel finishas. Suitable abrasives herein incl~de inorganic materials, especi~lly such materials as calciu~ carbonate and diatomaceous earth, as w211 ~S ma~eri~ls such as Fuller's earth, magnasium carbonata, China clay, attapulgite, calcium hydroxyapat$~e, calc~um orthophosphate, dolomit~ and the lik~. Th~ aforesaid inorganic materials can bQ qualified as "stron9 abrasiues". Synthetic organic abrasiues such as urea-formaldQhyde, methyl ~et~acrylate melamine-formaldehyde resins, polyethylene spheres and polyuinylchlorida can be aduantag~ously used in order to auoid scr~ltching on certain surfaces, especia~ly plastic ~3~
surfaces. ~hen such `'soft abrasiues" are used, strong builders can be incorporated in the composition.
Typically, abrasi~es havs a particle si~e range oF
lO-1000 microns and arQ used at concentrations of S% to 30%
in the compositions. Thickeners are frequently added to suspend the abrasives.
The organic soluent ~ The organic soluent to be used in the present composition has the gener~l formula RO(CH~CHO)nH
wherein R is an alkyl, alkenyl, or alkyl-aryl group ha~ing from 1 to 8 carbon atoms, and n is an integer From 1 to 4.
Preferably, R is a alkyl group containing 1 to 4 arbon atoms, and n is 1 or 2. Espeeially preferred 2 groups are n-butyl or isobutyl. Most preferred species are 1-n-butoxypropane-2-ol (n,1); and 1(2-n-bu~oxy-1-methylethoxy)propan~-2-ol (n=2), and mixtures thereof. 1-n-butoxyprop~ne-2-ol is esp~ci~lly prQferred.
Th~ organic sol~ent herein i5 u~ed at leuels of from 2 to 10X by weight of the composition, preferably 4 to 6~.
The sol~ent system can optionally contain, in combination with the soluent described herelnabove, water-solu~le C~RBITOL~ solu~nts or w~ter-soluble CELLOSOLU ~ solvent~. Wat~r-soluble C~R~IrOL~ solu~n~s are compounds of th~ 2-~2~alkoxyetho~y)ethanol class wherein thQ alkoxy group ls deri~ed from ethyl, propyl or butyl; a preferred water-soluble carbitol is 2-(2-butoxyethoxy30thanol also known as butyl carbitol.
Water-soluble CEL~OSOL~ ~ sol~nts 3re co~pound of thQ
2-alkoxyethox~ ethanol class, with 2-butoxyetho~yethanol being preferre~.
Suitable soluents to be used with the sol~ents o~ the in~ention ar~ also benzyl alcohol, and diols such as 2-ethyl-1,3-hexanediol and 2,2,4-trimethyl-1,3-pentanediol, The ~boue-des~ribed co-soluents can be used in leuels ranging from 0.1 to 5~ of the composition.
The compositions herein ~re substan~ially free o~
terpene-sol~ents. Inasmuch as soluents are generally used at leuels exceeding about 2~, terpen~s cannot be incorporated in the claimed compositions in such proportions. It is understood, howe~er, thæt relatiuely minor sub-additiue leuels of ~erpenes, e.g., below about 0.6~ ~calculated on the total cleanser composition), can be present originating from conuentional ingr~dients such as perfumes.
Optional Inqredients - In addition to the essential ingredient~ list~d hereinbefore, the pr~sen~ composition can contain additional components, which can be highly desirable.
For example, it is highly preferr~d that the compositions contain a deterge~t builder andfor metal ion sequestrant. Compounds classifiabls 4nd well-known in th~
art as detergent builders includ~ ~he nitrilotriacetat~s, (NT~ thylene diamine tetracet~te (EDT~), amino-polyphosphon~tes (DEQUEST~, watQr-soluble phosphates such as ~ri-p~lyphosphate ~nd sodium orth~ ~nd pyro-phosphates, silicates, and ~ixtures th~reof. Thess builders ar~ pref~rably not u6ed in co~bination wl~h strong abrasi~es lik~ c~lcium carbon~t~, but ar0 recommended in combination ~lth soft organic abr~siv~s like poly~inylchloride.
~3~
.- -- 7 --Metal ion sequestrants of lower metal sequestration .. . . _ . ... . ..
constant can aduantageously be used in combination with strong or soft abrasi~es. Those metal ion seguestrants include polycarboxylat~s, citrates. Preferred builders/sequestrants for us~ in the present inuention are NT~, EDT~, citrates and mixtures thereof. The buildersJs~ques~rant will be present at leu~ls of from 1% to 15%, preferably from 2% to 7~.
It is highly preferred, as well, to include soaps in the compositions of the in~ention. Soaps prepared from coconut oil fatty acids are preferred.
Soaps are used in amounts ranging from 0.2~ to 3~ by weight of the composition, preferably in an amount in excess of 1%, typically from 1% to 2~ by weight.
This le~el is clearly aboue leuels currently used in simllar compositions, since it has surprisingly been discouered that the presence of soaps at these higher levels not only prouides suds control, but also has a thickening effect on the compositions sontaining the specific organic sol~ent of the in~ention. This finding allows to keep the amount of thic~ener at a ~ery low le~el, thus substantially reducing certain drawbacks of thickeners, such as r~nsing difficult~es resulting from their us~ at substanti~l le~els.
Thickeners should pr~f~rably be included ln the compositions of the inu~ntion, in order to suspend ~he abr~siu~. ~oweusr ~he l~uel w~ll be kept under 2%, preferably from 0. 2~ to 1. 5~. Common thickeners such as the polyacrylates, xanthan gums, carboxymethyl celluloses, swellable smec~:ite clays, and th~ lik~, can b~ used hersin.
Optional co~ponents are also represented by ingredients typically used in commercial products to pro~ld~ aesthetic ~3~ Ei9~1) .. -- 8 --or additional product performance benefits. ~ypical ingredients include pH regulants, perfumes, dyes, optical brighteners, soil suspending agents, detersiue enzymes, gel-control agents, freeze-thaw stabilizers, bactericides, preseruati~es, and the like.
~ nother optional ingredient for use herein is represented by conuentional detergent hydrotropes. Examples of suitable hydrotropes are urea, monoethanolamine, diethanolamine, triethanolamine and thQ sodium potassium, ammonium and alkanol ammonium salts of xylene-, toluene-, ethylbenzene- and isopropyl-benzene sulfona~es. It is a particular feature of the present inuention, howeuer, th~t stable formulations can be prepared without tha need for hydrotropic materials oF th~s kind.
Th~ compositions herein typlcally contain up to about 90X water as a carrier. By way of example the water-le~el can uary in the range from ~.9. 50% to 80%. Water-alchol (e.~., ethanol, isopropanol, butanol, etc.) mi~tures can also be used. ~lkylated polysaccharides can be used to increaje the stability and performance characteristics of the co~positians.
Th~ compositions hersln are preferably formulated in the alkalin~ pH ran~e, generally in the rang~ of p~ 8-ll, preferably about 10-10.~. C~us~ics such as sodium hydroxide and sodium carbonate can be used to ad~ust and buffer the pH
as desired.

The testing conditions were as follows:
The test was run with the! aid of an Erich~en washability machine. ~ sponge of approximately 9.S x 5 x 4 cm was used after being carefully washed under hot running water and squeezed through drying rolls. ~9 of the undiluted cl~anser to be tes~ed w~s spread ouer one side of ~he sponge. The number of strokes of the cleaning machine uaried with the type of soil. Performance readings were done as soon as ~isible cleaning diFfrences b~came noticeable. The gradings wsre done visually by three judges working independently.
Th~ performance benefits were established uia paired comparison with duplicates as follows. ~ 0-4 scale was used whereby: 0 means no differQnce; 1 ~ prob~ble diFFer~nce; 2 =
