Description

COMPOSITIONS PRIOR TO CLEANING GLASS THAT HAVE SURGEY AGENTS OF LINEAR SULFATE RENT FIELD OF THE INVENTION This invention relates to compositions for cleaning glass, preferably clear liquid detergent compositions, for use in cleaning glass and, preferably, other hard surfaces.

BACKGROUND OF THE INVENTION It has recently been discovered that there is a strong consumer preference for liquid compositions to clean, especially compositions prepared for linting, which impart a smooth "sliding" feel, with good surface lubricity, as the cleaning implement rubs and dries. F-? At first glance, it seems pretty honorable to make a composition to clean that feels slippery, or imparts a soft "slipping" feel when used. One would think that it is possible to use a wax or silicone, as is known in the art, to provide good lubricity. I'm pregnant < It is well known that clean liquid compositions, and specifically compositions prepared for glass cleaning, require exceptionally good film / grain formation properties. Since good film / streaking properties are required especially for glass cleaners, the levels of tensio-active agents and other assets must be kept low in order to achieve this benefit. Therefore, the level of surfactant is too low to solubilize and / or stabilize silicones in the product, especially when it also has a hydrophobic perfume. Also, it is known in the art that the benefits of water formwork and antimony are preferred in glass cleaning compositions. These benefits of water formwork and irrigation are typically achieved by providing a composition that leaves behind a hydrophilic residue. * Waxes and silicones are reusable hydrophobic and therefore are completely incompatible with this requirement. It has been found that the long chain alkyl sulfate detergent surfactants, ie, u; or long lengths, provide the desired amount of surface lubricity as the composition is rubbed on the glass as well as contributing detergency and providing acceptable film / grain formation results and product clarity. In addition, the long chain alkyl sulfate surfactants are soluble in water and help to strengthen the surface water filtering capacity required to obtain benefits from water formwork and an + i-t intion.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates to detergent compositions, preferably compositions for cleaning * glass, which impart good surface lubricity and cleanliness without leaving undesirable levels of film and / or streaking. Preferably, said compositions contain an effective amount of substantive material that provides the glass with superior long-lasting hydrobility and is in the form of an aqueous, liquid, hard surface detergent composition having improved cleaning characteristics and good staining after re-wetting, comprising: (ñ) less than about 1%, by weight of the composition, of a linear alkyl sulfate detergent surfactant having the general formula: RO-SO3 I wherein M is a counterion soluble; R is an alkyl group having a chain length of about 20,000 to about 20,000, or mixtures of the same; wherein about 30% by weight of said surfactant has a chain length of O14; (13) from about 0.5% to about 30%, by weight of the composition, of a hydrophobic solvent having a hydrogen bonding parameter of from about 2 to 7.7; (Or the remainder being an aqueous solvent system selected from * the group consisting of polar water and non-aqueous solvents having a hydrogen bonding parameter greater than 7.7, and wherein said composition is essentially alcohol-free unreacted fatty and alkanolarnma compounds and wherein said composition is suitable for cleaning glass.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to detergent compositions, preferably hard surface liquid, aqueous detergent compositions having excellent characteristics of surface lubricity and film / streaking, comprising: (A) less than about 1%, by weight of the composition, of a linear alkyl sulfate detergent surfactant having the general formula: RO-SO3 I wherein M is a soluble counter ion; R is an aliquio group that has a chain length from about Ce to approximately Ois or mixtures thereof; where more than approximately > 0% by weight of said surfactant agent has a chain length of C14; (II) j around 0.5% to approximately J0%. by weight of the composition, of a hydrophilic solvent having a hydrogen bonding parameter of around 2 to 1. 7; (C) the remainder being an aqueous solvent system selected from the group consisting of polar water and non-aqueous solvents having a hydrogen bonding parameter greater than 7. 1; and wherein said composition is essentially free of unreacted fatty alcohol and alkanolamine compounds and wherein said composition is suitable for cleaning glass.

(A) THE PRIMARY SURVEY AGENT OF LONG CHAIN SULPHATE RENT The aqueous, liquid dimergent compositions of hard surface in the present contain less than about L%, by weight of the composition, preferably from about 0.01% to about 1%, most preferably from about 0.02% to about 0.3. %, by weight of the composition, of one or more chain lengths of a linear alcohol sulphate detergent surfactant having the generic formula: R - ü - SO3 M wherein M is any soluble counterion, preferably sodium, potassium, etc .; and wherein R is a group with a chain length of about 100% Ce to about Gis and mixtures thereof, preferably from about C12 to about Gis and inept thereof, much preterred about 0 ? At about Cis and mixtures of the isms, and wherein R is O14 by more than about 30%, preferably more than about 35%, most preferred by about 40%, by weight of the alkyl sulfate. All of the surface-active agent alkyl sulfate may contain R of chain length of C14 and longer, but more than 30% by weight of the alkyl surfactant agent must be of a chain length of CIA. Compositions containing only alkyl sulfate surfactants with longer chain lengths, i.e., C ß-18, provide good benefits of surface lubricity. However, these chain lengths, without the required amount of Cu chain lengths, exhibit poor film / streaking properties. On the other hand, the compositions which are made only of alkyl sulfate surfactants lower chain, ie *, C8-12 alkyl sulfate surfactants, provide acceptable film / streaking properties but exhibit poor surface lubricity properties. The presence of the chain length of C14 at levels of about 30% by weight of the alkyl sulfate surfactant on combination with other chain lengths, or soLa, provides a product with excellent surface lubricity properties and Lots of polythene formation properties. Particularly preferred compositions contain from about 0.05% to about 0.2%, by weight of the composition, of a mixture of C12 / 14 wherein the ratio by weight of C12 to C14 is about 1:10 to approximately 2: 1, preferably from about 1: 5 to about 1.5: 1, and most preferably from about 1: 3 to about 1: 1. It has been found that this combination provides sufficient surface lubricity at the same time avoiding the formation of inconvenient film / veining. The alcohol sulfate detergent starting materials are essentially free from unreacted fatty alcohol where the term "essentially free" is defined as having less than about 2%., by weight of the composition, preferably less than about 1.8% and preferably less than about L.5%, by weight of the unreacted fatty alcohol composition in a starting material 10% active. A very preferred alkyl sulfate surfactant is a mixture of Steamer Uft-Extra®, available from Stepan Company, with additional Cm alkyl sulfate added so that the ratio of C12 / 14 is almost 1: 1. The concentrated compositions can also be used to provide a less expensive product. When a higher concentration is used, that is, when the level of alkyl sulfate surfactant used is from about 0.10% to about 2.5%, by weight of the composition, dil tur is preferred. The composition before use The to clean a hard surface, especially glass. The dilution ratios of the alkyl sulfate concentrate to water may vary, preferably, from about 1: 1 to 1:10, preferably from about 1: 1.5 to 1: 5, and most preferred from aliquot. -about 1: 2 to 1: 5.The t.

Depending on the level of cleaning desired and / or the amount of hydrophobic material in the composition that needs to be solubilized, one may use only the amphocarboxy detergent surfactant, or may combine it with co-surfactant, preferably said surfactants. zwittorion cos. The "amphecarboxy" detergent surfactants herein preferably have the generic formula: R 'N (RI) (CH2) n N (R) (CH2) PC (0) OM wherein R' is a hydrophobic portion of Cß-io, typically a fatty acyl portion containing about 10 carbon atoms, which, in combination with the nitrogen atom forms a halo group, R 1 is hydrogen (preferably) or an alkyl group of C1-2, R2 is a C1-3alkyl or substituted C1-3alkyl, for example, hydroxy substi tude or substituted rnetoxy car box, preferably hydroxy ethyl, each n is an integer of the 3, each p is an integer of 1 to 2, preferably 1, and each 1 * 1 is a water soluble cation, typically an alkali metal, ammonium and / or alkanolamome cation. Said detergent surfactants are available, for example: from Witco under the trademark Rewo epc end-VR, having the formula C7 Hi 50 (0) MH (CH 2) 2 N (CH 2 CH 2 OH) CH 2 C ( 0) 0 (-) Na < +); Mona Industries, ba or the trademark Monatepc 1000R, having the formula C7H?

Zwitteponic detergent surfactants, which typically contain both a quaternary ammonium group and an ammonium group selected from sulfonate and carboxylate groups, are desired since they retain their amphoteric nature over most of the pH-value scale to clean hard surfaces. The sulphonate group is the preferred ionic group. The preferred detergent agents zwi tt eriom eos preferred have the generic formula: R3 ~ | C (0) -N (R «) - (CR52) nllftlN (R6) 2 (+) - (CR52) P1 -Y <;-) wherein each Y is preferably a carboxylate group (COO-) or sulfonate (SO3-), rnuy preferred sulfonate; wherein each R3 is a hydrocarbon, for example, an alkyl or alkylene group containing from about 8 to about 20, preferably from about 10 to about 18, preferably from about 12 to about 16 carbon atoms; wherein each (RM is either hydrogen, or a short chain alkyl, or substituted alkyl, containing from 1 to about 4 carbon atoms, preferably groups selected from the group consisting of methyl, ethyl, propyl, ethyl or propyl. substituted with hydroxyl, and mixtures thereof, preferably methyl, wherein each (R5) is selected from the group consisting of hydrogen and hydroxyl groups with no hydroxyl groups in any iCR52'P1 group, wherein (R6) it is like R *, except that it is preferably not hydrogen, where m is 0 or 1, and where each n1 and 1 are an integer from L to about 4, preferably from 2 to apr-ox, 3, most preferably about 3. The R3 groups can be branched, unsaturated, or both, and such structures can provide film / streaking benefits, even though they are used as part of a R3c group with straight-chain R3 alkyl groups. connected p to form ring structures such as midazole, pin dina, etc. The preferred hydrocarbyl nanoalkylenisulphobetam (HASB) detergent surfactants wherein rn = ly and Y is a sulphonate group, provide superior grease removal and / or film / veining and / or "anti-aging" and / or solubilization properties. fragrance. These hydrocarbon alkaline lensulous folates, and to a lesser degree, hydrocarbon arnideal, are excellent for use in hard surface cleaning detergent compositions, especially those formulated for use on glass and stains that are difficult to remove. They are even better when used with inonoet anolainma and / or bet -arninoal cano1 speci c as described in the present. A specific detergent surfactant is an acylcarbamide (hydroxypropylene) sulphobetaine C-14 fatty acid, for example the detergent surfactant available from Uitco Company co or a 40% active product under the brand name. "REUTERERIC AM CAS SulfohetameR." F- 1 level in the composition depends on the final level of dilution to make the washing solution. When the composition or wash solution containing the composition is used concentrated, it should contain from about 0.0% to about 1%, preferably from about 0.00% to about 0.5%, preferably from about 0.01% to about 0.25%, in Weight of the detergent surfactant composition. For the removal of stubborn stains, the level can and should be higher, typically from about 0% to about 10%, preferably from about 0.005% to about 2% by weight of the composition. The concentrated products typically contain from about 0% to about 10%, preferably from about 0.005% to about 5%, by weight of the composition. It is an advantage of the zwit erion co-detergent, for example HASB, that the compositions which contain it can be easily diluted by consumers since it does not interact with hardness cations as easily as conventional ammonia detergent surfactants. Zitropic detergents are also extremely effective at very low levels, for example, below 1%. The zwitterionic detergent surfactants are indicated in column 4 of the U.S. Patent. A.

While it is understood that the longer chain alkyl sulfate compounds described herein are considered to be the main surfactant system, additional associated surfactants may be added, including alkylsulfate surfactants of even more stringent chain lengths. The optional ammonium surfactants are suitably alkyl or alkylaryl compounds soluble in water, the alkyl has from about 6 to about 20 carbons, and includes a sulphite or sulphonate substituent group, but excludes the essential detergent surfactant of the quasulfate. Depending on the desired level of cleaning, Ib The ammonium essential detergent surfactant can only be used, or, preferably, the ammonium detergent surfactant can be combined with an associated surfactant, preferably an associated amphoteric surfactant. Associated surfactants may also be used. Nonionic surfactants, for example ethoxylated alcohols and / or alkylphenols, but are not preterm. The ammonia detergent surfactants herein preferably have the formula Aonepca: R9- (R o) 0 -? - S03 (~) M (+) wherein R9 is a C6-C alkyl chain, preferably an alkyl chain of Cß-Ciß; R10, when present, is an alkylene chain of C6-C20, preferably an alkylene chain of Ce-Cie, a femlene group of Ce HA, U 0; and M is the same as before. The patents and references described hereinabove and incorporated by reference also describe other detergent surfactants, for example, ammonia detergent surfactants and, less preferably, nonionics, which may be used in small amounts, preferably as surfactants associated with the detergent surfactant. Alkyl sulfate is preferred and the associated detergent surfactant amphoteric / zwitepom is preferred. The level of the associated surfactant may be small in relation to the main surfactant. Some of these are alkyl- and alkylethoxylate- (polyethoxylate) sulphates, sulfonates of Ib. paraffin, olefin sulfonates, alkoxy-side alcohols (especially ethoxides) and alkyl phenols, alkyl phenol sulfonates, fa-sulfonates of fatty acids and fatty acid esters, and the like, which are well known in the detergent art. When the pH is above about 9.5, the detergent surfactants which are amphoteric at low pH are convenient as are the associated ammonia detergent surfactants. For example, suitable surfactants are detergent surfactants which are C12-C18 alkylenecarbonylenulphonate sulfonates, for example compounds having the formula RC (0) - NH ~ (C2H4) -N (02- U0H) -CH2CH (0H) CH2S03M, wherein R is an alkyl group containing from about 9 to about 18 carbon atoms and M is a compatible cation. These detergent surfactants are available as M? Ranol® CS, OS, JS, etc. The adopted CTFA name for these surfactants is cocoanfohydroxypropyl sulphonate. It is preferred that the compositions be substantially free of the phthalenesulphonate. In general, the detergent surfactants useful herein contain a hydrophobic group, typically contain an alkyl group on the C9-C18 scale, V, optionally, one or more linking groups such as ether or arnide, preferably knotted groups. Ammonium detergent tonsions can be used in the form of their sodium, potassium or cannon arnon 10 salts, for example trientanollammonium salts.; nonionic, non-preferred, generally contain from about 5 to about 17 oxygen groups of ethylene. Some suitable surfactants for use herein in small amounts are one or more of the following: linear sodium alkyl benzene sulfate (LAS) of Ce-Cie, particularly LAS of C11-C12; the sodium salt of a cocoalkylene sulfonate containing 3 rnoles of ethylene oxide; the adduct of a random secondary alcohol having a scale of alkyl chain lengths of 11 to 15 carbon atoms and an average of 2 to 10 ethylene oxide entities, of which several commercially available examples are Tergitol® 15-S-3 , Terg?

The ratio of the Cu alkyl sulfate detergent surfactant to associated surfactant, or associated surfactants, is typically from about: L to about 1: 1.

(C) HYDROPHOBIC SOLVENT To improve cleaning in the liquid compositions, a hydrophobic solvent having cleaning activity can be used. The solvents used in the hard surface cleaning compositions herein may be any of the well known "degreasing" solvents commonly used, for example in the dry cleaning industry, in the hard surface cleaning industry and in the rtetal industry istep a. A useful definition of these solvents can be derived from the solubility parameters indicated in "The Hoy", a Union Carbide publication, incorporated herein by reference. The most useful parameter seems to be the hydrogen bonding parameter that is calculated by means of the formula: where TH is the hydrogen binding parameter, a is the reagent number, (Log a = 3.39066 Tb / Tc - 0.15848-Log 11 / d), and tl "is the solubility parameter that is obtained from the formula: where? H25 is the heat * of vaporization at 25 ° C, R is the gas constant (1.987 cal / rnoles / degrees), T is the absolute temperature in ° K, Tb is the boiling point in ° K, Tc is the critical temperature in ° K, d is the density in g / ml, and M is the molecular weight. For the compositions herein, the hydrogen binding parameters are preferably less than about 7.7, preferably about 2 to about 7, and very preferably about 3 to about 6. Solvents with low numbers are increasingly They are difficult to solubilize in the compositions and have a higher tendency to cause tarnishing on the glass. Higher numbers require more solvent to provide good grease / oil cleaning. Fobic hydro solvents are typically used at a level of from about 0.5% to about 30%, preferably from about 2% to about 15%, most preferably from about 3% to about 8%. Diluted compositions typically have solvents at a level of from about 1% to about 10%, pre fepblement e from approximately 3% to approximately 6%. The concentrated compositions contain from about 10% to about 30%, preferably from about 10% to about 20% solvent. Many of these solvents comprise halogenated hydrocarbon or hydrocarbon entities of the type aLqu? or cycloalkyl lo, and have a boiling point rnuy above room temperature, i.e. above about 20 ° C. The formulation of compositions of the present type will be guided in the selection of the solvent associated in part by the need to provide good fat cutting properties, and in part by aesthetic considerations. For example, kerosene hydrocarbons work very well for cutting gr-asa in the present compositions, but they can be malodorous *. The l - e? oseno must be exceptionally clean before it can be used, even in commercial situations. For domestic use, where bad odors will not be tolerated.? '.' Formally, you should select * solvents that have a relatively pleasant odor, or odors that can be reasonably modified with perfumes. the aromatic alkyl solvents of Ce-C9, especially the alkylbenzenes of C & -C9, preferably octyl benzene, exhibit excellent grlya removal properties and have a lightly pleasant odor. Likewise, the olefin solvents have a boiling point of at least about 100 ° C, especially alf-olefms; preferably 1-dequene or 1-dodequene are excellent fat-removing solvents. Generally, the glycol ethers useful herein have the formula RH 0- (R 20-) mlH, wherein each RH is an alkyl group containing from about 3 to about 8 carbon atoms, each Ri2 is either ethylene or Full prop, and rnI is a number from 1 to about 3. The highly preferred glycol ethers are selected from the group consisting of monopropylene glycol monohydroxypropyl ether, dipropylene glycol monobutyl ether, rnonopropylene glycol monobutyl ether, ether and ethylene glycol monoethyl ether, ethylene ether. glycolrnonobuti 1 LCO, diethylene glycol-nitrogen-ox ether? Co, onoethylene glycol monohexyl ether, ether onoeti lengl icoirnonobut? 1 co, and mixtures of the same. A particularly preferred type of solvent for these hard surface cleaning compositions is that they have from 6 to about 5 carbon atoms in their molecular structure. The diol solvents ?? Fepdos have a solubility in water of about 0.1 to about 20 g / 100 g of water at 20 ° C. Solvents such as pine oil, orange terpene, benzyl alcohol, n-hexanol, phthalic acid esters of C 1-4 alcohols, butoxypropanol, But? LCarb?

For an improved odor, the butoxypropanol solvent should have no ace of about 20%, preferably not more than about 10%, preferably not more than about 7%, of the secondary viceroy in which the butoxy group is attached to the secondary atom of the butoxy group. propanol (D) OPTIONAL SOURCE OF RLCRLINIDRD The compositions of this invention may contain an optional source of alkalinity. Suitable compounds that may be used include, but are not limited to, alkali metal hydroxides, ie sodium, potassium etc., and sodium carbonates or bicarbonates, the alkalinity being present at a level from 0% to about 0"2% by weight of the composition. Typically, said source of alkalinity is present at a level of approximately 0.001% to approximately 0.1%, I preferred approximately from (1.005% to approximately 0.05%, by weight of the composition.) The disadvantage of using alkanolamine compounds as A source of alkalinity in the present invention These alkanolarnin compounds interfere with the surface lubricity benefit achieved by the long chain alkyl sulfate surfactants.Therefore, this composition is essentially free from canolamine compounds. "Essentially free" as defined herein means less than about 0.5%, preferably less than about 0.1%, preferably less than about 0.01%.

(E) SOLUBLE OF CARBONATE AND / OR BICARBONATE SOLUBLE OPTIONAL The water-soluble alkali metal bicarbonate and / or carbonate salts such as sodium bicarbonate, potassium bicarbonate, potassium carbonate, cesium carbonate, sodium carbonate and mixtures thereof are added to the composition of the present invention To improve the elimination of the film / grain formation when the product is dried on the surface with a rag as it is typically done in the cleaning of the glass. The preferred salts are sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, their respective hydrates and mixtures thereof. The carbonate salts • >; Alkali metal bicarbonate soluble in water and sunlight are typically present at a level of from about% to about 0.5%, preferably from about 0.001% to about 0.1%, preferably from about 0.005% to about 0.05% by weight of the composition. The pH in the composition, at least immcially, during use is from about 7 to about 11, preferably from about 7.5 to about 10.5, and preferably from about 8 to about 10. The pH is typically measured in the product.

(F) OPTIONAL SUBSTANTIVE MATERIAL THAT INCREASES THE HYDROPHILIC CAPACITY OF THE GLASS An optional but preferred ingredient of this invention is the material which improves the hydrophilic ability of the surface being treated, especially the glass. This increase in hydrophilic capacity provides an improved appearance when the surface is rewetted and then dried. Water is "peeled" from the surface and therefore minimizes the formation of, for example, "rain spots" that form after drying. Many materials can provide this benefit, fierce the preferred materials are the polymers that contain groups hydrophilic, especially carboxylate or sulfonate groups. Other materials that may provide their activity and hydrophilic capacity 2b they include cationic materials that also contain hydrophilic grids and polymers that contain multiple ether bonds. The cationic materials include cationic sugar and / or starch derivatives and the typical block copolymer detergent surfactants based on blends of polypropylene oxide and ethylen oxide are representative of polyether fluids. However, the polyether materials are less substantive. Preferred polycarboxylate polymers are those formed by the polyethylene ionization of monomers, at least some of which contain carboxylic functionality. The common monorneros include acrylic acid, aleic acid, ethylene, vimlpirrol i dona, metacplico acid, metacriloet lbetama, etc. Preferred poly-sulphonate polymers are those based on a base structure of 1-letyrene reindeer. The preferred polymers for substantivity are those that have higher molecular weights. For example, polyacrylic acid having molecular weights below about 10,000 is not particularly substantive and therefore does not normally provide phyllic hydro capacity for three rewetings with all compositions, albeit with higher and / or higher levels. surfactant agents such as amphoteric and / or zwitterionic detergent surfactants, The molecular debris below approximately 1,000 can provide * certain results. In general, polymers must have molecular weights of more than 1,000,000, preferably more than about: 0,000, most preferably more than 300,000 and even more preferably more than about 400,000. It has also been found that high molecular weight polymers, for example, those having ace molecular weights of about 3,000,000, are extremely difficult to formulate and are less effective in providing anti-stain benefits than lower molecular weight polymers. Accordingly, the molecular weight should be normal, especially for polyacrylates, from about 20,000 to about 3,000,000; preferably from about 20,000 to about 2,500,000 very effi- ciently from about 300,000 to about 2,000,000 and even more preferably from about 400,000 to about 1,500,000. One advantage of certain polycarboxylate polymers is the effective detergency of such polymers. Surprisingly, such polymers do not alter the elution of film / grain and like other dewatering improvers, they provide increased cleaning effectiveness in typical and common "difficult to remove" soils that contain particulate matter. Some polymers, especially polycarbonate polymers, thicken compositions that are aqueous liquids. This may be desirable .. However, when the compositions are placed in containers with devices of spraying by spray, the compositions are not desirably so thick as to require excessive trigger pressure. Typically, the viscosity under the shear stress should be less than about 200 cp, preferably less than about 100 cp, most preferably less than about 50 cp. However, it may be desirable to have thick compositions to inhibit the flow of the composition away from the surface, especially the vertical surfaces. Examples of materials suitable for use in the present include polyvinylpyrrole idone / acrylic acid sold under the name "Acryl? Done" by ISP, polystyrene sulphonic acid and salts of polystyrene fonate sold under the name "Versaflex" by National Starch and polyacrylic acid sold under the name "Accurner" R by- Rohrn to Hass. The level of the substantive material should normally be from about 0% to about 1.0%, preferably from about 0.01% to about 0.5%, preferably from about 0.02% to about 0.2% by weight of the composition. In general, lower molecular weight materials such as the lower molecular weight polyacrylic acid, for example, those having molecular weights below 100% and especially about 2,000, do not provide good anti-joint benefits after re-wetting. Initially, especially at the lowest levels, for example, approximately 0.02%. Only the most effective materials should be used at the lowest levels. To use materials of lower molecular weight, substantivity, for example, should be increased by adding groups that provide improved fixation to the surface, such as cationic groups. or materials should be used at higher levels, for example, more than 0.05%,.

(G) AQUEOUS SOLVENT SYSTEM The balance of the formula is typically water and non-aqueous polar solvents with only minimal cleaning action such as methanol, ethane L, isopropanol, and glycolic, glycol ethers having a hydrogen bonding parameter of more than 7.7, propylene glycol and mixtures of them, preferably ethanol. The level polar solvent * non-aqueous solvent is usually greater amount are prepared more concentrated formulas. Typically, the level of the non-aqueous polar solvent is from about 0.5% to about 40%, preferably from about 1% to about 10%, preferably from about 2% to about 8% (especially for "dilute" compositions) and the Water level is from about 50% to about 99%, preferably from about 75% to about 95%.

(H) OPTIONAL INGREDIENTS The compositions herein may also contain other adjuvants that are known in the art for the detergent compositions. Preferably they are not used at levels that cause unacceptable film / streaking characteristics. Non-limiting examples of such auxiliaries are: Enzymes such as proteases, "Hydrotoxins such as sodium toluensul fonate, curnensul sodium fonate and potassium xylene sulphate, and cosmetic enhancement ingredients such as dyes and perfumes, as long as no The cleaning of the glass is not adversely affected by the elimination of the peeling / streaking of the glass. The hard surface cleaning products contain some perfumes to provide an aesthetic benefit to the smell and to cover any "chemical" odor that the product may have. The main function of a small amount of the highly volatile and low boiling perus components (which have low boiling points) in these perfumes is to improve the fragrance aroma of the product itself, instead of moving the Subsequent odor of the surface that is being cleaned, however, some high-boiling and less volatile perfume ingr-edient.es can pro see a fresh and clear impression on surfaces, and it is sometimes desirable that these ingredients are 3L deposited and are present on the dry surface. Perfumes are preferably those that are more soluble in water and / or volatile to minimize film formation and veining. The p r * fumes useful in the present are described in more detail in the U.S. patent. No. 5,108,660, Michael, issued April 28, 1992, in column 8 lines 48 to 68, column 9 lines 68, and column 10 lines 1 to 24, said patent and especially said specific portion being incorporated into a reference. Antibacterial agents may be present, but preferably only at low levels to avoid the problems of film / streaking. Antibacterial agents are avoided? Hydrophobic materials such as orthobenzyl-para-chloro phenol. SL are present, such materials must be maintained at levels below approximately 0.1%. Stabilizing ingredients may typically be present to stabilize the hydrotoxic ingredients, for example, perfume. Stabilizing ingredients include acetic acid and propionic acids and their salts, for example, NH4, MEA, Na, K, etc., preferably acetic acid and the C2-C6 alkane ejioles, preferably butane diol. The stabilizing ingredients do not work according to any known principle. However, the combination of a zwitterionic detergent surfactant with a detergent agent - detergent surfactant of linear amine carboxyl carboxylate, ammonium detergent surfactant, nonionic detergent surfactant or mixtures thereof and a stabilizing agent, can create a microenhancing effect. . The amount of stabilizing ingredient is typically from about 0.01% to about 0.5%, preferably from about 0.02% to about 0.2%. The ratio of hydrophobic material, for example, perfume that can be stabilized in the product is related to the total surfactant and is typically in an amount that provides a ratio of surfactant to hydrophobic aterial of from about 1: 2 to about 2: 1. Other detergency builders which are efficient for hard surface cleaners and which have reduced film / streak formation characteristics at critical levels may also be present in the compositions of the invention. The addition of specific detergency builders at critical levels to the present composition further improves cleaning without the problem of film / streaking that usually occurs when detergency builders are added to hard surface cleaners. . It is not necessary to establish a compromise between improved cleaning and acceptable film / grain removal results, which is especially important for hard surface cleaners that are also aimed at cleaning the glass. These compositions containing these additional specific detergency m ers have exceptionally good cleaning properties. They also have exceptionally good "gloss properties", that is, when they are used to clean * glossy surfaces, without rinsing, <; They have a lesser tendency than, for example, the products from carbonate to leave an opaque finish on the surface and film / vetted formation. Additional and suitable optional detergency builders include etiiendiarninotetraacetic acid salts (hereinafter EDTA), citric acid, t-ploacetic acid (hereinafter NTA), sodium carboxymethyl succinate acid, N- (2-hydroxyl) acid. rop? l) - sodium and acid nano diacetic N-diet i lengl? col-N, Nd? acet? co (hereinafter DIDA). The salts are preferably compatible and include ammonium, sodium, potassium and / or alkanolarnome salts. The salt of ammonium was preferred as will be described hereafter. A preferred detergency builder is NIA (eg, sodium), a preferred builder is citrate (eg, sodium or methane ethanol), and an improved one - EDTA (eg, sodium) is most preferred. These optional and additional detergency builders, when present, are typically at levels of about 0.01% to about.%, Very prerequisite to about 0.02% to about 0.3%, most preferably about 0.02% a *? p i * ox utely O.IC.%. The levels of these electors? additional detergents present in the washing solution used to clean glass should be less than approximately 0.2%. Therefore, typically, dilution is highly preferred for glass cleaning, while full power is preferred for general cleaning purposes, depending on the concentration of the product. Typically the best film removal / streaking results occur when the detergency builder is combined with amphoteric and / or zwitterionic surfactant compositions, although an improvement is also observed with the ammonia or aniomco / no detergent surfactant compositions. ionic. The invention is illustrated by the following non-limiting examples.

Static friction height test A 30.5 x 30.5 crn shaft glass blade is sprayed with the moon spray product from a no-spraying device) and with a paper towel towel it is almost dry. A block of Plexiglas 550 grams is wrapped with a paper towel turning a sheet and bending twice to form a box. The towel is attached to the bottom of the block that is stretched stiff without wrinkles or creases and there is no tape on 1 Dt lower surface than '? tai a in contact with the glass. The block is placed over the glass to one end. The end of the glass is raised slowly '* - until the block begins to move. The distance in which the glass was lifted is measured. The higher the friction is, the greater the friction and the static friction height. A normal dry glass has a high coefficient of friction (0.9-1.0), and therefore a high static friction height (more than 13 crn with this method).

Final result cleaning test Procedure: Five sprays of the product to be tested are applied to a glass window of 0.609 mx 0.914 rn (which can be soiled with body oils from a hand shaft imprint) and cleaned with two towels the paper until it is almost dry, simulating the actual use of the product by the consumer. Graduation: expert judges were used to evaluate the specific areas of application of the product, the amount of film removal / veining, with the help of a reflector- to simulate * a solar ray. A numerical value that describes the quality of the final result is assigned to each product. For the test results reported here, a scale of 0--6 was used, in which 0 = good final result without film / veining formation, and 6 - very defi nitive final result.

For relatively low and constant surfactant levels (approximately 0.1 to 0.2%) that are consistent with good final results, C14 chain lengths and long lengths provide the highest smoothness (the lowest static friction height). The qualitative evaluation shows that Formulas 1-3 provide a markedly improved surface lubricity while drying with a rag from which Formulas 4-5 provide.
