Description
~ WO 9513302~ 2 1 9 I t 3 5 PCT/lJSgY05839 CLEANING COMPOSITIONS
Technical Field The present invention relates to liquid compositions for cleaning hard surfaces.
Backaround It is well known in the art that it is a desirable feature of a liquid hard surface cleaner that it should have a certain viscosity. Indeed, viscosity allows a controlled handling, more spe~,irically dispensing, of the product during use, as compared to a thinner product. Also, viscosity allows a better action of the product on non-horizontal surfaces, such as toilets, bath tubs and the like.
That is because viscosity prevents the product from running down said surfaces, like thinner liquids would. Preferably, viscosity will be built UF~ by a so-called self-thickening system as opposed to using a thickener compound for that specific purpose. Indeed, thickeners, such as gums or polymers have at least one drawback that they affect the formula cost, while providing only one benefit, which is thickening. They do not pdl li~.iUdle to the actual cleaning of the surface and therefore represent ''inert" materials. Also, some lI,i~kene are d~ Idl to the physical stability of the products they are formulated in.
20 It is known in the art to formulate self thickened cr,"".osiliolls where the Il lick~l~il ,y is achieved without the use of polymeric thickeners, see for instance EP 518 401 and EP 21 581.
But there are some drawbacks ~cso~ with viscosity. And a main draY~back 25 is that viscous products are typically diflicult to rinse away, :"ue~,iric~"y because viscous products have a good cling onto surfaces and current self thickening systems lead to the formation of stable foams. Thus viscosity and ease of rinsing are somewhat conflicting requirements, but both are desirable in a single product for cleaning hard surfaces. It is thus an object of the pr2sent 30 invention to provide a hard surface cleaning uullllJosiLiull which is viscous by means of a self Illicht~ lg system, and which is nevertheless easy to rinse away.
In response we have found that such a l,u,,,i o~itiu,, could be formulated by 35 using an amine oxide, an amine or mixtures thereof, in culllbilldIiul~ v~ith a secondary or primary Illùllob, dl n,l~ed alkyl sulfate or sulfonate in a mildly rlcidic system further ~,ullluliaillg a hydrotrope and citric acid.

derived from said CullluOSiLiUlla is that they are low foaming, both in the sense of the amount of foam initially generated during use~ as well as in terms of foam stability. This benefit adds to the ease of rinsing benefit already obtained with the "I,le~ d~ Lic" benefit derived from the viscosity profile of the uul~,uosiliul, Summarv of the invention The present invention is an aqueous viscous COlllUU::liikJll cun),u,i~i"g an amine oxide, or an amine or mixtures thereof, a secondary, or primary ",ull~bld""lled alkyl sulfate or sulfonate in excess of said amine oxide, amine or mix~ures thereof, a hydrotrope, and an organic acid~ said ~u~posiLiu~ being formu~ated at a pH of from û.5 to 7.
Detailed description of the invention The cu~,uùsiLiol~s according to the present invention are aqueous cu",,u~si~io"s. Therefore they comprise from 90% to 60% by weight of the total uu~,uo:,iliull of water. One of the achievements of the present invention is that the viscosity build up described hereinafter can be achieved with such a high amount of water, i.e. a sma~l amount of actives.
As a second essential ingredient~ the Cul~luOai~iullS herein comprise an amine oxide, or amine, or mixtures thereof. Suitable amine oxides to be used according to the present invention are according to the formula R1R2R3NO, where R1 is a hy~lucdllJoll chain Cu",,ulisillg from 6 to 18 carbon atoms, and R2 and R3 are independently hydlucdl~oll chains comprising up to 3 carbon atoms, or mixtures thereof. Preferred amine oxides for use herein are amine oxides where R1 comprises from 8 to 14 carbon atoms, preferably are C8-C10 amine oxide or C12-C14 amine oxide and R2 and R3 are both methyl. Such a C8-C10 amine oxide is UU~ ltllUiC~ 'y available under the trade name Barlox ~
10S, from Lonza. Such a C~2-C14 amine oxide suitable to be used herein is collllll~lcidlly available under the name Genanimox @) LA from Hoechst.
Another suitable amine oxide for use herein which is cu,,,,,,e,~ic,lly available is Aromox ~ DMMCO-W from Akzo. Suitable amines to be used according to the present invention are according to the formula R1R2R3N, where R1 is a hydlucdl~oll chain comprising from 6 to 18 carbon atoms, and R2 and R3 are illd~pt:lldullLly hydrogen or hydrocarbon chains cull~uliaillg up to 3 carbon atoms, or mixtures thereof. Preferred amines for use herein are amines where R1 comprises from 8 to 12 carbon atoms and R2 and R3 are i,)d~pe,ldd"lly methyl or hydrogen.
~ W095133024 2 1 9 l 1 35 PC'rlUS9C;105839 Preferably the total amount of amine oxides, or amines, or mixtures thereof, in the compositions according to the present invention is from û.3% to 5.~0% by weight of the total UUIll,UOSi~iUI 1, more preferably 0.5% to 1.2%.
s As a third essential ingredient, the compositions herein comprise a secondary,or primary ",ul,ob,d"~l~ed alkyl sulfate or sulfonate, or mixtures thereof. By secondary alkyl sulfate or sulfonate, it is meant herein an alkyl sulfate or sulfonate where the alkyl chain comprises from 10 to 16 carbon atoms, preferably from 12 to 14, and where this alkyl chain is not sulfated or sulfonated at either terminus. By primary ,,,ol~ou,~,,ul,ed sulfate or sulfonate, it is meant herein an alkyl sulfate or sulfonate where the alkyl chain comprises from 1û to 16 carbon atoms, preferably from 12 to 14, and where this alkyl chain is branched, comprises an alkyl substituent, at least one carbon removed from the sulfate or sulfonate group, i.e. in position 2 or further on the alkyl chain, numbering from the sulfate or sulfonate group. We have found that it is essential to have a branched alkyl chain, i.e. using a linear alkyl chain does not provide the benefits according to the present invention, but it appears that it does not matter which branching is present in the alkyl chain. We have obtained good results using an alkyl sulfate where the alkyl chain comprised a 20 total of 12 carbon atoms, sodium 2-butyl octyl sulphate. Such an alkyl sulfate is cullllll~lui~'!y available from Condea under the trade name Isofol ~ 12 S. Anexample of an alkyl sulphonate would be Hostapur @) SAS availabl~! from Hoechst. The amount of secondary, or primary ~lu~ouldll~ ed alkyl sulfate or sulfonate present in the culll,uoaiLiu,,a herein depends amongst other things onthe amount of amine oxide, or amine or mixtures thereof present, but suitable amounts of secondary, or primary ,,,u,,ou,d,,~l,ed alkyl sulfates or sulfonates herein are generally uo,,,,u,ised between 3% and 20% by weight of the total uu",uosiIion, preferably between 4% and 7%. It is essential that the .,o,,,uosiLio,ls herein should comprise said secondary, or primary 30 ",ollu~ld,~-,l,ed alkyl sulfate or sulfonate in excess of amine oxide, amine or mixtures thereof, i.e. in the ,_u",l.osiliu,1s herein, the amount of alkyl sulfate or sulfonate should be greater than the amount of amine oxide, amine or mixtures thereof.
3s As a fourth essential ingredient, the uullluosiLio~ls herein comprise an olrganic acid, or mixtures thereof. Preferably, the organic acids for use herein will have a pK of less than 6. Suitable such organic acids are selected from the group WO 9S/3302J 2 ~ 9 1 1 3 5 PCTIIJS95/05839 consisting of citric acid, lactic acid, glycolic acid, succinic acid, glutaric acid and adipic acid, and mixtures thereof. A mixture of said acids suitable for use herein is 1rJllllll~l~idlly available from BASF under the trade name of Sokalan @
DCS. A preferred acid for use herein is citric acid. Such acids have been s found to provide the desired benefit in viscosity build up as well as uu~uos;lio~
stability. We have found that no phase S~ ./dl dLiUI I occurred for at least 30 days at 20C, and up to 30 days at 50C in the case of citric acid. The amount of organic acid herein may vary ddpe"~ g on the amount of other ingredients herein, but suitable amounts of acids herein are generally comprised between o 1% and 20~3 by weight of the total cu",,uosiliol-, preferab!y between 4% and 8%, particularly when citric acid is used.
The flfth essential ingredient herein is a hydrotrope. By hydrotrope, it is meant herein an agent which helps solubilizing the hydrophobic i"y,ddie"L~ in the 15 ~ u~pOs;iiul-S. We have found that the hydrotrope pdl LiUiUdi~:s to the building of the viscosity and contributes to increase the stability of the composition.
Suitable hydrotropes for use herein include nonionic surfactants and organic solvents, and mixtures thereof. Suitable nonionics for use herein are alkoxylated alcohols generally cùr"~,,isi"y from 6 to 16 carbon atoms in the 20 alkyi chain of the alcohol. Typical alkoxylation groups are ethoxy and propoxy groups. Such compounds are co"""e, ~ially available under the series Dobanol from Shell, or Lutensol ~ from BASF with a wide variety of chain length and alkoxylation degrees. Preferred nonionic surfactants for use herein are according to the formuia R(X)nH, were R is an alkyl chain having from 6 to 16 25 carbon atoms, preferably 6 to 10, X is an alkoxy group, preferably ethoxy or a mixture of ethoxy and propoxy, n is an integer of from 4 to 30 preferably 5 to 8.
Suitable solYents for use herein are organic solvents, preferably alcohols or ethers thereof, or mixtures thereof. Commonly aYailable solvents which are suitable for use herein include normal-butoxy propoxy propanol (n-BPP), 30 propane diol and butyl diglycol ether (BDGE). The amount of hydrotrope may vary ;l~pe"di"g on the amount of other ill~ JiellL~ herein, but suitable amounts of hydrotrope herein are generally comprised between 1% and 10%
by weight of the total composition, preferably between 2% and 4%.
35 The sixth essential feature herein is the pH, which is required to be of from 0.5 to 7. But we have observed that, as the l,~llll~JosiLiol~s herein are formulatedclose to the higher end of this pH range, the lower the overall solubility of the ~ W0 95133024 2 t 9 1 1 3 5 P~
cullluosiliù,l, thus the more difficult it is to illc~l,uuldLu hydrophobic ingredients, typically perfumes. Also, beyond pH 7, we have not been able to provide the desired viscosity. At the opposite end, as the pH gets low a higher amount of the amine oxide described hereinbefore is needed. A preferred pH range herein is of from about 2 to 6, most preferably 3 to 4.
The uu~ ucsiLiolls herein can be made by mixing together all il lU~ lLakeeping aâ the last one the amine oxide, or amine or mixtures thereof, or the secondary, or primary monobranched alkyl sulfate or sulfonate. Until this last ingredient is added, no or little viscosity build up is observed. Then, upon adding the amine oxidel amine or mixtures thereof, or the secondary, or primary i"u"ob,d,1~l,ed alkyl sulfate or sulfonate, an opaque solution is formedwhich thickens on the complete addition of all ~u~ ullel lLa~ This opaque solution becomes less opaque on thickening. And in some cases lldl~s~ "L
products have been obtained. Under an optical "~i~, ùscuue the opacity can be seen to be due to a bicontinuous phase, which on thickening, we speculate, leads to the formation of tightly packed vesicles which provides the desired viscosity. It would appear that there remains a non-sol~h;'i~Pd Cu""Jullt",L
present. The cu,,,uosiliu~ls herein eventually reach a viscosity of from 50 cps to 50ûO cps at 60 RPM shear rate with spindle #2 with a B,ouh~rield viscometer, preferably from 100 cps to 300 cps.
In this system, it is believed that the amine oxide and/or amine are plul~lldL~dl due to the acidic pH, and form an ion pair with the secondary alkyl sulfate or sulfonate in the system. This ion pair constitutes a hy~l,uul~.L,ic specie. We speculate that the secondary alkyl sulfate, which is present in exce.ss, in ~,ulllLJil IdliOIl with the hydrotrope/hydrotropic species and the organic acid,forms an extended/network structure within the aqueous phase. This leads to the 11 li~,h~ )g of the composition to provide the desired viscosity. Additionally, the presence of the h~ilulJllobi~, ion pair per se appears to confer d,lliru~,ni"~
properties, thus leading to a rinsing benefit.
As an optional but highly preferred ingredient, ~,ullluoi~iLiu~ hereir~ will comprise a perfume ingredient, usually a mixture of such ill~u,l~ llLa. Indeed, perfume ingredients which are typically h~,dluul1ubil, materials has been found to provide a contribution to building viscosity, perhaps through supporting the phase stnucture of the product, as well as improving the overall stability of the .. ,, _ _, ,, _ _ _ ... ... ....
product. By perfume, it is meant herein constituents of a perfume which are added thereto only or primarily for their olfactive contribution. Perfume ~u",l r,,lenl~ may be natural products such as essential oils, absolutes, resinoids, resins, concrètes, etc., and synthetic perfume components such as 5 hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, acetals, ketals, nitriles, etc., including saturated and unsaturated compounds, aliphatic, carbocyclic and heterocyclic compounds.

This benefit adds to the ease of rinsing benefit already obtained with the "I,le~ d~ Lic" benefit derived from the viscosity profile of the uul~,uosiliul, Summarv of the invention The present invention is an aqueous viscous COlllUU::liikJll cun),u,i~i"g an amine oxide, or an amine or mixtures thereof, a secondary, or primary ",ull~bld""lled alkyl sulfate or sulfonate in excess of said amine oxide, amine or mix~ures thereof, a hydrotrope, and an organic acid~ said ~u~posiLiu~ being formu~ated at a pH of from û.5 to 7.
Detailed description of the invention The cu~,uùsiLiol~s according to the present invention are aqueous cu",,u~si~io"s. Therefore they comprise from 90% to 60% by weight of the total uu~,uo:,iliull of water. One of the achievements of the present invention is that the viscosity build up described hereinafter can be achieved with such a high amount of water, i.e. a sma~l amount of actives.
As a second essential ingredient~ the Cul~luOai~iullS herein comprise an amine oxide, or amine, or mixtures thereof. Suitable amine oxides to be used according to the present invention are according to the formula R1R2R3NO, where R1 is a hy~lucdllJoll chain Cu",,ulisillg from 6 to 18 carbon atoms, and R2 and R3 are independently hydlucdl~oll chains comprising up to 3 carbon atoms, or mixtures thereof. Preferred amine oxides for use herein are amine oxides where R1 comprises from 8 to 14 carbon atoms, preferably are C8-C10 amine oxide or C12-C14 amine oxide and R2 and R3 are both methyl. Such a C8-C10 amine oxide is UU~ ltllUiC~ 'y available under the trade name Barlox ~
10S, from Lonza. Such a C~2-C14 amine oxide suitable to be used herein is collllll~lcidlly available under the name Genanimox @) LA from Hoechst.
Another suitable amine oxide for use herein which is cu,,,,,,e,~ic,lly available is Aromox ~ DMMCO-W from Akzo. Suitable amines to be used according to the present invention are according to the formula R1R2R3N, where R1 is a hydlucdl~oll chain comprising from 6 to 18 carbon atoms, and R2 and R3 are illd~pt:lldullLly hydrogen or hydrocarbon chains cull~uliaillg up to 3 carbon atoms, or mixtures thereof. Preferred amines for use herein are amines where R1 comprises from 8 to 12 carbon atoms and R2 and R3 are i,)d~pe,ldd"lly methyl or hydrogen.
~ W095133024 2 1 9 l 1 35 PC'rlUS9C;105839 Preferably the total amount of amine oxides, or amines, or mixtures thereof, in the compositions according to the present invention is from û.3% to 5.~0% by weight of the total UUIll,UOSi~iUI 1, more preferably 0.5% to 1.2%.
s As a third essential ingredient, the compositions herein comprise a secondary,or primary ",ul,ob,d"~l~ed alkyl sulfate or sulfonate, or mixtures thereof. By secondary alkyl sulfate or sulfonate, it is meant herein an alkyl sulfate or sulfonate where the alkyl chain comprises from 10 to 16 carbon atoms, preferably from 12 to 14, and where this alkyl chain is not sulfated or sulfonated at either terminus. By primary ,,,ol~ou,~,,ul,ed sulfate or sulfonate, it is meant herein an alkyl sulfate or sulfonate where the alkyl chain comprises from 1û to 16 carbon atoms, preferably from 12 to 14, and where this alkyl chain is branched, comprises an alkyl substituent, at least one carbon removed from the sulfate or sulfonate group, i.e. in position 2 or further on the alkyl chain, numbering from the sulfate or sulfonate group. We have found that it is essential to have a branched alkyl chain, i.e. using a linear alkyl chain does not provide the benefits according to the present invention, but it appears that it does not matter which branching is present in the alkyl chain. We have obtained good results using an alkyl sulfate where the alkyl chain comprised a 20 total of 12 carbon atoms, sodium 2-butyl octyl sulphate. Such an alkyl sulfate is cullllll~lui~'!y available from Condea under the trade name Isofol ~ 12 S. Anexample of an alkyl sulphonate would be Hostapur @) SAS availabl~! from Hoechst. The amount of secondary, or primary ~lu~ouldll~ ed alkyl sulfate or sulfonate present in the culll,uoaiLiu,,a herein depends amongst other things onthe amount of amine oxide, or amine or mixtures thereof present, but suitable amounts of secondary, or primary ,,,u,,ou,d,,~l,ed alkyl sulfates or sulfonates herein are generally uo,,,,u,ised between 3% and 20% by weight of the total uu",uosiIion, preferably between 4% and 7%. It is essential that the .,o,,,uosiLio,ls herein should comprise said secondary, or primary 30 ",ollu~ld,~-,l,ed alkyl sulfate or sulfonate in excess of amine oxide, amine or mixtures thereof, i.e. in the ,_u",l.osiliu,1s herein, the amount of alkyl sulfate or sulfonate should be greater than the amount of amine oxide, amine or mixtures thereof.
3s As a fourth essential ingredient, the uullluosiLio~ls herein comprise an olrganic acid, or mixtures thereof. Preferably, the organic acids for use herein will have a pK of less than 6. Suitable such organic acids are selected from the group WO 9S/3302J 2 ~ 9 1 1 3 5 PCTIIJS95/05839 consisting of citric acid, lactic acid, glycolic acid, succinic acid, glutaric acid and adipic acid, and mixtures thereof. A mixture of said acids suitable for use herein is 1rJllllll~l~idlly available from BASF under the trade name of Sokalan @
DCS. A preferred acid for use herein is citric acid. Such acids have been s found to provide the desired benefit in viscosity build up as well as uu~uos;lio~
stability. We have found that no phase S~ ./dl dLiUI I occurred for at least 30 days at 20C, and up to 30 days at 50C in the case of citric acid. The amount of organic acid herein may vary ddpe"~ g on the amount of other ingredients herein, but suitable amounts of acids herein are generally comprised between o 1% and 20~3 by weight of the total cu",,uosiliol-, preferab!y between 4% and 8%, particularly when citric acid is used.
The flfth essential ingredient herein is a hydrotrope. By hydrotrope, it is meant herein an agent which helps solubilizing the hydrophobic i"y,ddie"L~ in the 15 ~ u~pOs;iiul-S. We have found that the hydrotrope pdl LiUiUdi~:s to the building of the viscosity and contributes to increase the stability of the composition.
Suitable hydrotropes for use herein include nonionic surfactants and organic solvents, and mixtures thereof. Suitable nonionics for use herein are alkoxylated alcohols generally cùr"~,,isi"y from 6 to 16 carbon atoms in the 20 alkyi chain of the alcohol. Typical alkoxylation groups are ethoxy and propoxy groups. Such compounds are co"""e, ~ially available under the series Dobanol from Shell, or Lutensol ~ from BASF with a wide variety of chain length and alkoxylation degrees. Preferred nonionic surfactants for use herein are according to the formuia R(X)nH, were R is an alkyl chain having from 6 to 16 25 carbon atoms, preferably 6 to 10, X is an alkoxy group, preferably ethoxy or a mixture of ethoxy and propoxy, n is an integer of from 4 to 30 preferably 5 to 8.
Suitable solYents for use herein are organic solvents, preferably alcohols or ethers thereof, or mixtures thereof. Commonly aYailable solvents which are suitable for use herein include normal-butoxy propoxy propanol (n-BPP), 30 propane diol and butyl diglycol ether (BDGE). The amount of hydrotrope may vary ;l~pe"di"g on the amount of other ill~ JiellL~ herein, but suitable amounts of hydrotrope herein are generally comprised between 1% and 10%
by weight of the total composition, preferably between 2% and 4%.
35 The sixth essential feature herein is the pH, which is required to be of from 0.5 to 7. But we have observed that, as the l,~llll~JosiLiol~s herein are formulatedclose to the higher end of this pH range, the lower the overall solubility of the ~ W0 95133024 2 t 9 1 1 3 5 P~
cullluosiliù,l, thus the more difficult it is to illc~l,uuldLu hydrophobic ingredients, typically perfumes. Also, beyond pH 7, we have not been able to provide the desired viscosity. At the opposite end, as the pH gets low a higher amount of the amine oxide described hereinbefore is needed. A preferred pH range herein is of from about 2 to 6, most preferably 3 to 4.
The uu~ ucsiLiolls herein can be made by mixing together all il lU~ lLakeeping aâ the last one the amine oxide, or amine or mixtures thereof, or the secondary, or primary monobranched alkyl sulfate or sulfonate. Until this last ingredient is added, no or little viscosity build up is observed. Then, upon adding the amine oxidel amine or mixtures thereof, or the secondary, or primary i"u"ob,d,1~l,ed alkyl sulfate or sulfonate, an opaque solution is formedwhich thickens on the complete addition of all ~u~ ullel lLa~ This opaque solution becomes less opaque on thickening. And in some cases lldl~s~ "L
products have been obtained. Under an optical "~i~, ùscuue the opacity can be seen to be due to a bicontinuous phase, which on thickening, we speculate, leads to the formation of tightly packed vesicles which provides the desired viscosity. It would appear that there remains a non-sol~h;'i~Pd Cu""Jullt",L
present. The cu,,,uosiliu~ls herein eventually reach a viscosity of from 50 cps to 50ûO cps at 60 RPM shear rate with spindle #2 with a B,ouh~rield viscometer, preferably from 100 cps to 300 cps.
In this system, it is believed that the amine oxide and/or amine are plul~lldL~dl due to the acidic pH, and form an ion pair with the secondary alkyl sulfate or sulfonate in the system. This ion pair constitutes a hy~l,uul~.L,ic specie. We speculate that the secondary alkyl sulfate, which is present in exce.ss, in ~,ulllLJil IdliOIl with the hydrotrope/hydrotropic species and the organic acid,forms an extended/network structure within the aqueous phase. This leads to the 11 li~,h~ )g of the composition to provide the desired viscosity. Additionally, the presence of the h~ilulJllobi~, ion pair per se appears to confer d,lliru~,ni"~
properties, thus leading to a rinsing benefit.
As an optional but highly preferred ingredient, ~,ullluoi~iLiu~ hereir~ will comprise a perfume ingredient, usually a mixture of such ill~u,l~ llLa. Indeed, perfume ingredients which are typically h~,dluul1ubil, materials has been found to provide a contribution to building viscosity, perhaps through supporting the phase stnucture of the product, as well as improving the overall stability of the .. ,, _ _, ,, _ _ _ ... ... ....
product. By perfume, it is meant herein constituents of a perfume which are added thereto only or primarily for their olfactive contribution.
