Definitions
- the invention relates to a non-rinse, isotropic hard surface cleaner especially adapted to be used on glossy or smooth, hard surfaces, such as glass windows and the like, which removes soils deposited thereon, while significantly reducing the amount of residue caused by unremoved soil, cleaner, or a combination thereof.
- Corn et al., E.P. 0393772 and E.P. 0428816, describe hard surface cleaners containing anionic surfactants with ammonium counterions, and additional adjuncts G.B. 2,160,887 describes a cleaning system in which a combination of nonionic and anionic surfactants (including an alkanolamine salt alkyl sulfate) is contended to enhance cleaning efficacy.
- nonionic and anionic surfactants including an alkanolamine salt alkyl sulfate
- WO 91/11505 describes a glass cleaner containing a zwitterionic surfactant, monoethanolamine and/or beta-aminoalkanols as solvents/buffers for assertedly improving cleaning and reducing filming spotting.
- the invention provides an aqueous, hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:
- R 3 wherein R 1 is C 5.20 alkyl, : and R 3 are C M alkyl, R 1 -C-NH-(CH,) B -, or -(CH,) p -OH, although R 2 and R 3 do not have to be equal, and n is 1-5, preferably 3, and p is 1-6, preferably 2-3;
- the invention provides an all-temperature, improved glass and other hard surface cleaner having excellent streaking filming performance as compared to the prior art.
- the improvement is especially striking when cleaning glass and other glossy, hard surfaces with the invention.
- the cleaner further comprises (e) an effective amount of an additional dispersant, namely, an n-alkylpyrrolidone.
- an additional dispersant namely, an n-alkylpyrrolidone.
- This particular adjunct has proven to be surprisingly effective at both dispersing highly insoluble organic materials, particularly, fragrance oils, while simultaneously enhancing or maintaining the effective minimization of streaking/filming of the surfaces cleaned with the inventive cleaner.
- the addition of discrete amounts of certain anionic surfactants e.g., alkylsulfates, can provide other desirable cleaning attributes.
- Other dispersants such as nonionic surfactants can also provide desirable functions, such as fragrance dispersion, added cleaning, etc.
- the invention further comprises a method of cleaning soils from hard surfaces by applying said inventive cleaner to said soil (such as by, e.g., using a pump or trigger sprayer to conveniently and effectively deliver metered amounts of the cleaner to the soiled surface), and removing both from said surface.
- the invention is an improved cleaning, substantially non-streaking/filming hard surface cleaner especially adapted to be used on glossy or smooth, hard surfaces, emblematic of which is glass.
- the cleaner benefits from the use of a novel surfactant which contributes unexpectedly to the complete removal of soils and the cleaner from the surface being cleaned.
- the cleaner itself has the following ingredients:
- R 3 wherein R 1 is C 520 alkyl, R 2 and R 3 are C M alkyl, R 1 -C-NH-(CH 2 ) n - or -(CH 2 ) p -OH, although R 2 and R 3 do not have to be equal, and n is 1-5, preferably 3, and p is 1-6, preferably 2-3;
- adjuncts in small amounts such as fragrance, dye and the like can be included to provide desirable attributes of such adjuncts.
- a further adjunct e) a 1 -alkyl-2-pyrrolidone is added in amounts effective to disperse the fragrance and to improve or maintain the reduced streaking/filming performance of the inventive cleaner.
- an anionic surfactant is present in discrete amounts to provide other desirable cleaning attributes.
- the solvents useful in this invention are organic solvents with a vapor pressure of at least 0.001 mm Hg at 25°C and soluble to the extent of at least lg/ 100ml water.
- the upper limit of vapor pressure appears to be about 100 mm Hg at 25°C.
- Vapor pressure is a useful measure for determining the applicability of the given solvent, since one would select a solvent which will volatilize sufficiently so as to leave no visible residue.
- the organic solvent of the invention is preferably selected from C, ⁇ alkanol, C 3 24 alkylene glycol ether, and mixtures thereof. However, other, less water soluble or dispersible organic solvents may also be utilized.
- the alkanol can be selected from methanol, ethanol, n-propanol, isopropanol, butanol, pentanol, hexanol, their various positional isomers, and mixtures of the foregoing.
- isopropanol usually in conjunction with a glycol ether.
- diols such as methylene, ethylene, propylene and butylene glycols, and mixtures thereof.
- solvents such as amines, ketones, ethers, hydrocarbons and halides may be used.
- amines e.g., monoethanolamine, diethanolamine, etc.
- buffers as described further below in 4
- these amines can be bifunctional herein, although it is cautioned that, strictly from the point of aesthetics, amines have a characteristic odor which some may find not entirely pleasing.
- solvents can be found in Kirk-Othmer. Encyclopedia of Chemical Technology 3rd. Vol. 21, pp. 377-401 (1983), incorporated by reference herein.
- the alkylene glycol ether solvents can include ethylene glycol monobutyl ether, ethylene glycol monopropyl ether, propylene glycol monopropyl ether, propylene glycol monobutyl ether, and mixtures thereof.
- One preferred glycol ether is ethylene glycol, monobutyl ether, also known as 2-butoxyethanol, sold as Butyl Cellosolve by Union Carbide.
- a particularly preferred alkylene glycol ether is propylene glycol, t-butyl ether, which is commercially sold as Arcosolve PTB, by Arco Chemical Co. It has the structure:
- propylene glycol t-butyl ether is especially preferred in the formulations of the invention.
- Propylene glycol n-butyl ether is also a suitable solvent for use herein. This particular solvent readily improves the non-streaking/non-filming performance. If mixtures of solvents are used, the amounts and ratios of such solvents used are important to determine the optimum cleaning and streak/film performances of the inventive cleaner. It is preferred to limit the total amount of solvent to no more than 50%, more preferably no more than 25%, and most preferably, no more than 15%, of the cleaner. However, in some of the compositions of this invention, no solvent may be present.
- a preferred range is about 1-15%, and if a mixed solvent system of alkanol glycol ether is used, the ratio of alkanol to alkylene glycol ether should be about 1.20 to 20.1, more preferably about 1 10 to 1 : 10 and most preferably about 1 :5 to 5: 1.
- terpene derivatives include terpene hydrocarbons with a functional group.
- Effective te ⁇ enes with a functional group include, but are not limited to, alcohols, ethers, esters, aldehydes and ketones.
- terpene alcohols including, for example, verbenol, transpinocarveol, c/s-2-pinanol, nopol, iso-borneol, carbeol, piperitol, thymol, -terpineol, te ⁇ inen-4-ol, menthol, 1,8-te ⁇ in, dihydro-te ⁇ ineol, nerol, geraniol, linalool, citronellol, hydroxycitronellol, 3,7-dimethyl octanol, dihydro-myrcenol, -te ⁇ ineol, tetrahydro-alloocimenol and perillalcohol; Te ⁇ ene ethers and esters, including, for example, 1,8-cineole, 1,4-cineole, isobornyl methylether, rose
- Te ⁇ ene hydrocarbons with functional groups which appear suitable for use in the present invention are discussed in substantially greater detail by Simonsen and Ross, The Te ⁇ enes. Volumes I-V, Cambridge University Press, 2nd Ed., 1947 (inco ⁇ orated herein by reference thereto). See also, the commonly assigned U.S. Patent 5,279,758, ofChoy, inco ⁇ orated herein by reference thereto.
- the surfactant is a semi-polar nonionic surfactant known as an alkylamidoalkylenedialkylamine oxide. Its structure is shown below:
- R 1 is C 5.20 alkyl
- R 2 and R 3 are C M alkyl
- n is 1-5, preferably 3, and p is 1-6, preferably 2-3.
- the surfactant could be ethoxylated (1-10 moles of EO/mole) or propoxylated (1-10 moles of PO/mole).
- the preferred surfactant is available from various sources, including from Lonza Chemical Company, as a cocoamidopropyldimethyl amine oxide, sold under the brand name Barlox C. These particular surfactants have proven to have su ⁇ risingly excellent streaking filming characteristics when formulated with the solvents and buffers of the invention. It is not understood why this is so, since this particular surfactant has not heretofore been disclosed, taught or suggested for inco ⁇ oration in a substantially non-streaking/filming hard surface cleaner. It is speculated that this surfactant interacts particularly well with buffers to disperse same, resulting in the unexpectedly desirable performance in streaking/filming tests. Further, when this surfactant is used in the hard surface cleaners of the invention, it has been observed that the cleaner can be sprayed on a glass surface, allowed to dry, and yet still can be easily wiped off.
- these surfactants when formulated into the inventive hard surface cleaners, will outperform comparative surfactants, such as alkylamidoalkylenedialkylbetaines, e.g., as disclosed in Michael, U.S. Patent 5,342,549.
- alkylamidoalkylenedialkylamine oxide surfactants of the invention will outperform comparative surfactants under challenging environmental conditions (high and low temperature), as well as in tests where the cleaner is merely sprayed onto a hard surface and not wiped or wicked off
- additional surfactants for various cleaning pu ⁇ oses. It is of course cautioned that adding additional surfactants, indeed, any other adjunct materials (such as dyes, fragrances, high ionic strength materials, such as chelating agents and builders), must be carefully monitored to avoid the leaving a residue from the added material itself. For example, one can add a small amount of an anionic surfactant, for both cleaning and desirable foaming characteristics.
- the anionic surfactant is selected from alkyl sulfates, alkylbenzene sulfonates, alkylsulfonates, iseothionates, alkylethersulfates, ⁇ -olefin sulfonates, alkyl taurates, alkyl sarcosinates and the like. Each of these surfactants is generally available as the alkali metal, alkaline earth and ammonium salts thereof.
- the preferred anionic surfactant is alkyl sulfate, more preferably, C ⁇ alkyl sulfates.
- One particularly preferred sulfate is sodium lauryl (C 12 ) sulfate, available from
- Stepan Chemical Co. under the brand name Stepanol WAC. Because it appears desirable to limit the total amount of sodium ion present in the invention, it may also be preferred to use the alkaline earth salts of alkyl sulfates, particularly magnesium, and, less preferably, calcium, to bolster non- streaking/non-filming performance.
- alkaline earth salts of alkyl sulfates particularly magnesium, and, less preferably, calcium
- Magnesium salts of the anionic surfactants are commercially available, however, a viable alternative is to form the magnesium salts in situ by the addition of soluble Mg salts, such as MgC ⁇ , and the like.
- Calcium salts suitable for use would be CaCL,, and the like.
- the level of these salts may be as high as 200 ppm, although less than 100 ppm is preferred, especially less than 50 ppm.
- nonionic surfactants may be desirable for inclusion and are selected from alkoxylated alcohols, alkoxylated ether phenols, and other semi-polar nonionics, such as the non-derivatized straight chain trialkyl amine oxides.
- the alkoxylated alcohols include ethoxylated, and ethoxylated and propoxylated C ⁇ alcohols, with about 2-10 moles of ethylene oxide, or 1-10 and 1-10 moles of ethylene and propylene oxide per mole of alcohol, respectively.
- the preferred ethoxylated alcohols include those available from Union Carbide under the trademark “Triton” and from Shell Chemical Company under the trademark “Neodol.”
- the straight chain semi-polar amine oxides could be added, although, again, it is noted that these surfactants have themselves been used as the primary surfactant in comparative hard surface cleaners (e.g., Garabedian et al., U.S. Patent Application Serial No. 08/134,348, filed October 8, 1993). These have the general configuration:
- R" wherein R is C ⁇ alkyl, and R' and R" are both C M alkyl, although R' and R" do not have to be equal.
- These amine oxides can also be ethoxylated or propoxylated.
- the preferred amine oxide is lauryl amine oxide, such as Barlox 12, from Lonza Chemical Company.
- amphoteric surfactant may also be desirable for addition in discrete amounts, although it is also observed that it has been used in comparative formulations against which the invention has been compared and in which the invention was found generally to have superior performance.
- the amphoteric surfactant is typically an alkylbetaine or a sulfobetaine. Especially preferred are alkylamidoalkyldialkylbetaines. These have the structure:
- R" is C ⁇ alkyl
- R b and R c are both C M alkyl, although R b and R c do not have to be equal, and m can be 1-5, preferably 3, and o can be 1-5, preferably 1.
- alkylbetaines can also be ethoxylated or propoxylated.
- the preferred alkylbetaine is a cocoamidopropyldimethyl betaine called Lonzaine CO, available from Lonza Chemical Co.
- Other vendors are Henkel KGaA, which provides Velvetex AB, and Witco Chemical Co., which offers Rewoteric AMB-15, both of which products are cocobetaines.
- the at least one semi-polar nonionic surfactant, alkylamidoalkylene- dialkylamine oxide is present, in an amount of about 0.001-10%, more preferably about 0.001-7.5%, and most preferably about 0.001-2%, total surfactant.
- the resulting composition is often referred to, commercially as a "concentrate.”
- the concentrate can be diluted by a factor of 1 : 1 to 1 :500 concentrate: water, in order to obtain various concentrations for specific cleaning pu ⁇ oses.
- the amounts added are generally about 0.001-2%, more preferably 0.002-0.75% semi-polar nonionic surfactant, generally about 0-1%, more preferably 0-.75% anionic surfactant and generally 0.005-2%, more preferably 0.01-1% alkylpyrrolidone surfactant, in the cleaner.
- the ratios of surfactants are generally about 1 : 1 : 10 to 1 ,000: 1 : 1 semi-polar nonionic/anionic/alkylpyrrolidone, when all three are present. If just two surfactants are used, the ratios will be about 1 : 1 ,000 to 1 ,000: 1.
- the l-alkyl-2-pyrrolidones can provide a dual function in this invention.
- one of the desirable adjuncts which are added to this system are fragrances, which are typically water-immiscible to slightly water-soluble oils.
- a co-solvent or other dispersing means was necessary.
- 1 -alkyl-2-pyrrolidones were particularly effective at so solubilizing the fragrance oils.
- the 1 -alkyl-2-pyrrolidones also improve the cleaning performance of the cleaner, especially in streaking/filming.
- the compound could also function in place of, or in addition to, the surfactants present in the composition.
- the compound has the general structure:
- R 4 wherein R 4 is a C ⁇ alkyl, or R 5 NHCOR 6 , and R 5 is C,. 6 alkyl and R 6 is C ⁇ alkyl.
- a particularly preferred alkyl pyrrolidone is lauryl pyrrolidone, sold by ISF Chemicals under the brand name Surfadone. Relatively low amounts of the alkyl pyrrolidone are used, preferably, about 0.001-2%, when the level of fragrance is from about 0.01-5%.
- the buffer system comprises a nitrogenous buffer which is added to the aqueous hard surface cleaners of the invention so as to result in a pH of greater than 6.5, more preferably, between 7 and 14, most preferably between 7 and 13.
- the buffer can be selected from the group consisting of: ammonium or alkaline earth carbamates, guanidine derivatives, ammonium carbonate, ammomum bicarbonate, diammonium carbonate, alkanolamines, ammonium hydroxide, ammonia (which forms ammonium hydroxide in situ when added to water) alkoxylalkylamines and alkyleneamines and mixtures thereof.
- the co-buffer is selected from ammonium and alkaline earth metal hydroxides.
- the nitrogenous buffer is a significant aspect of the invention. Because of its presence, greatly enhanced reduction in streaking and filming of hard surfaces is achieved after the inventive cleaner is used to clean the same.
- the preferred nitrogenous buffers are ammonium carbamate, monoethanolamine, ammonium bicarbonate, ammonium carbonate and ammonium hydroxide.
- Ammomum carbamate has the structure NH OO ' NH * ,,. Use of this particularly preferred buffer obtains outstanding reduction in filming/streaking. It is available from BASF Co ⁇ .
- Monoethanolamine is an alkanolamine.
- Other examples of this type of buffer are diethanolamine, triethanolamine and isopropanolamine.
- the alkanolamines can also function as solvents, although it is intended that the alkanolamines herein be used primarily in their role as buffer.
- Monoethanolamine has proven to have particularly effective performance in the inventive cleaners.
- Ammonium carbonate and bicarbonate are other, further desirable buffers.
- buffers are guanidine derivatives, such as diaminoguanidine and guanidine carbonate; alkoxyalkylamines, such as isopropoxypropylamine, butoxypropylamine, ethoxypropylamine and methoxypropylamine; and alkylamines, such as ethyleneamine, ethylenediamine, ethylenetriamine, ethylenetetramine, diethylenetetramine, triethylenetetramine, tetraethylenepentamine, N,N-dimethylethylenediamine, N-methylenediamine, and other variations of the alkyl and amine substituents.
- guanidine derivatives such as diaminoguanidine and guanidine carbonate
- alkoxyalkylamines such as isopropoxypropylamine, butoxypropylamine, ethoxypropylamine and methoxypropylamine
- alkylamines such as ethyleneamine, ethylenediamine, ethylenetriamine, ethylenet
- ammonium or alkaline earth hydroxide is especially preferred.
- ammonium hydroxide which volatilizes relatively easily after being applied, resulting in minimal residue.
- Ammonium hydroxide also emulsifies fatty soils to a certain extent.
- the amount of nitrogenous buffer added should be in the range of 0.01-2%, more preferably 0.01-1%, by weight of the cleaner, while hydroxide, if present, should be added in the range of 0.001-1% by weight of the cleaner.
- the cleaner is an aqueous cleaner with relatively low levels of actives
- the principal ingredient is water, which should be present at a level of at least about 50%, more preferably at least about 80%, and most preferably, at least about 90%. Deionized water is most preferred.
- adjuncts can be added for improving cleaning performance or aesthetic qualities of the cleaner.
- Adjuncts for cleaning include additional surfactants, such as those described in Kirk-Othmer. Encyclopedia of Chemical Technology. 3rd Ed., Volume 22, pp. 332-432 (Marcel-Dekker, 1983), which are inco ⁇ orated herein by reference.
- Inorganic builders, such as silicates and phosphates, are generally avoided in this cleaner, especially those which will contribute a large amount of solids in the formulation which may leave a residue.
- Aesthetic adjuncts include fragrances, such as those available from Givaudan-Roure, Belmay, Henkel KGaA, Firmenich, Dragoc , IFF, Quest and others, and dyes and pigments which can be solubilized or suspended in the formulation, such as diaminoanthraquinones.
- the fragrance oils typically require a dispersant, which role is fulfilled by the alkylpyrrolidone.
- a fragrance is well dispersed by the alkylpyrrolidone while at least maintaining, if not improving, the non-streaking/non-filming performance of the inventive cleaner.
- the amounts of these cleaning and aesthetic adjuncts should be in the range of 0-2%, more preferably 0-1%.
- hydrotropes specifically, short chain alkylaryl sulfonates, more specifically, C alkylaryl sulfonates, such as, without limitation, benzene, naphthalene, xylene, cumene and toluene sulfonates.
- C alkylaryl sulfonates such as, without limitation, benzene, naphthalene, xylene, cumene and toluene sulfonates.
- alkali metal salts typically alkali metal salts and, although it has been cautioned herein that the total level of alkali metal salts is to be limited, in fact, for certain pu ⁇ oses, such as hard surface cleaning (e.g., tile, composite materials such as Formica® and Corian® countertops, and the like), inco ⁇ oration of hydrotropes in a discrete level may be quite acceptable.
- the preferred hydrotrope herein is alkali metal xylene sulfonate, wherein the alkali metal is potassium, sodium or lithium.
- An ammomum salt may also be acceptable.
- sodium xylene sulfonate is used in a preferred composition containing amine oxides (at least, the non-derivatized, straight chain trialkylamine oxides), it has been su ⁇ risingly found that yellowing of certain types of uncolored or white plastic surfaces (especially polyvinyl chloride) is essentially avoided or mitigated.
- amine oxide may partition to such plastic surfaces and the short chain alkylaryl sulfonate interferes with such binding.
- the amount of short chain alkylaryl sulfonate may be kept economically low, i.e., preferably about 0.01-2%, more preferably 0.02-1% and most preferably, about 0.05-1%.
- Preferred hydrotropes include sodium xylene sulfonate, sold in various active levels by Stepan Chemical Company under the brand name Stepanate SXS. Other preferred hydrotropes may be found from Colborn et al., U.S. Patent 4,863,633, column 8, line 20 to column 10, line 22, which are inco ⁇ orated by reference thereto.
- Examples 2-1 1 to further demonstrate the uniqueness and unusual behavior of the cocoamidopropylamine oxide surfactant and selected buffers, experiments were conducted in which the invention (Examples 6-9, each example containing a different nitrogenous buffer) was compared against comparative formulations containing different surfactants.
- the formulations were simply sprayed via a trigger sprayer (consistently, two short bursts) onto glass mirror tiles, and not wiped or wicked off. Then, as discussed above, graded by an expert panel of graders on a 0 to 10 scale (the samples were randomized and the panelists were not informed of the identity of the samples).
- Examples 2-5 contained cocoamidopropyldimethylbetaine.
- Examples 2-9 did not contain any sodium lauryl sulfate, alkylpyrrolidone. Thus, the streaking/filming performance attributable primarily to the surfactant was tested here.
- Examples 10-1 are considered to be "fully formulated” and are representative of what could be sold commercially.
- Example 23 In the next series of experiments (Examples 23-26), streaking/filming data (again, glass mirror tiles, graded by panelists on a 0-10 scale) were collected for new batches of product, aged 8 weeks, and heated and cooled (environmental challenges). The environmentally challenged samples were 2-3 week old product. Examples 23-25 represent the invention (containing cocoamidopropyldimethylamine oxide), while 26 is commercial product A (with cocoamidopropyldimethylbetaine). Example 23 contains both sodium lauryl sulfate (SLS) and dodecylpyrrolidone, Example 24 contains neither, and Example 25 contains only SLS. TABLE IV
- Example 26 demonstrate that the inventive formulations uniformly have excellent streaking/filming performance, most notably at elevated temperatures, versus the commercial formulation, Example 26. This demonstrates the excellent all temperature performance of the inventive cleaners.
- the inventive cleaner thus performs well at both hot and cold environments (-30° C to 70° C).
