The present invention is a sprayable cleaning gel composition having the surprising and unexpected property of having a very high viscosity (over about 900 cP) and yet is easily sprayable, having an excellent spray distribution on a surface upon which it is sprayed, and further providing an anti-static quality to the surface.
The present invention, in a first embodiment thereof, encompasses a substantially homogeneous sprayable cleaning gel composition which is substantially free of suspended encapsulated particles. Preferably, the sprayable cleaning gel composition according to the present invention is housed in a spray applicator.
A preferred embodiment of the sprayable cleaning gel composition in accordance with the present invention generally comprises (percentages are by weight of the composition): from about 75% to about 98% of a carrier fluid; from about 0.005% to about 20% of a surfactant component comprising at least one surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures of the above; and from about 0.01% to about 10% of a water-soluble polymeric thickening agent; wherein the sprayable cleaning gel composition has a viscosity from about 900 cP to about 5,550 cP, preferably from about 1,500 cP to about 4,500 cP and most preferably from about 2,700 cP to about 3,000 cP.
The preferred embodiment of the sprayable cleaning gel composition in accordance with the present invention preferably further comprises: from about 1% to about 20% of at least one supplemental solvent for dissolving oil-based particles in water; and from about 0.001% to about 5% of a dispersant to promote homogeneous distribution of the mixture components in the composition and to break up and disperse soils in application of the sprayable cleaning gel composition. Preferred supplemental solvents for use in the composition hereof are those selected from the group consisting of ethylene glycol ethers and propylene glycol ethers.
The sprayable cleaning gel composition according to the preferred embodiment hereof may, optionally, include additional adjuvants such as, e.g., a fragrance or a colorant.
The sprayable cleaning gel composition according to the present invention has an innate property of providing a very low level of residual static electric charge which is left on a surface after it has been wiped thereoff. This anti-static property is important in that surface wiping ordinarily tends to generate significant static electric charge on the surface which causes dust to collect thereupon; accordingly, minimization of static electric charge on the cleaned surface is important to providing a long term clean surface. To provide even further and longer lasting minimization of static electric charge on the cleaned surface after wiping, the sprayable cleaning gel further comprises preferably from about 0.05% to about 1.0% of an anti-static agent. In this regard, it has been discovered that a water soluble silicone based lubricant and softener serves as both a surfactant and an unexpectedly excellent anti-static agent.
The present invention also encompasses a spray applicator in combination with the sprayable cleaning gel composition hereof. This combination allows for more efficient cleaning of surfaces than was possible with the prior art cleaners.
The present invention further encompasses a method of cleaning a surface using the sprayable cleaning gel composition and spray applicator hereof. A method in accordance with the present invention, generally, comprises the steps of: 1) spraying a substantially homogeneous sprayable cleaning gel composition onto a surface to be cleaned, the sprayable cleaning gel composition comprising: from about 75% to about 98% of a carrier liquid; from about 0.005% to about 20% of a surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures of the above; optionally from about 0.05% to about 1.0% of an anti-static agent; and from about 0.01% to about 10% of a water-soluble polymeric thickening agent, wherein the sprayable cleaning gel composition has a viscosity from about 900 centipoise (cP) to about 5,550 cP, and wherein the sprayable cleaning gel composition substantially clings to and dwells on the surface rather than running downwardly thereon under the effect of gravity at standard temperature and pressure (25 degrees Centigrade and 1 atmosphere pressure); 2) spreading the sprayable cleaning gel composition around the surface with a wiping article, such as a cloth rag or a paper towel; and 3) wiping the sprayable cleaning gel composition off the surface via the wiping article.
Accordingly, it is an object of the present invention to provide a sprayable cleaning gel composition which will cling to and dwell on a surface to be cleaned longer than the prior art compositions.
It is an additional object of the present invention to provide a sprayable cleaning gel which will provide improved product to surface contact during cleaning.
It is another object of the present invention to provide a sprayable, yet viscous, cleaning gel composition which exhibits a unique physical appearance which is substantially transparent with air bubbles entrained therein.
It is yet another object of the present invention to provide a sprayable cleaning gel composition which includes anti-static properties so that when the sprayable cleaning gel composition is wiped off a surface, static electric charge thereon is significantly minimized.
It is a further object of the present invention to provide a sprayable cleaning gel composition and method of use thereof which will be more efficient and therefore less wasteful in application than currently available spray cleaners.
These, and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
Referring now to the drawing, a spray applicator 10 is shown in an operator's hand 15 operating to dispense a sprayable cleaning gel composition 20 according to the present invention from the spray applicator onto a vertical surface 25 which is shown by way of example as a window pane 30. When an operator's hand 15 presses downwardly on a spray head 90, the sprayable cleaning gel composition 20 is atomized by the spray applicator 10 into a spray 35 which adheres to the vertical surface 25 thereby forming a deposit 40 of sprayable cleaning gel composition 20 thereon.
As will be further detailed herein, the sprayable cleaning gel composition 20 is a relatively viscous, substantially homogeneous gelatinous composition which is substantially free of suspended encapsulated particles. The sprayable cleaning gel composition 20 according to the present invention is also, preferably, free from chlorine bleaches in order to avoid any reaction between a reactive hypochlorite bleach and oxidation-sensitive perfumes or surfactants. Another reason that bleaches are, preferably, excluded from the sprayable cleaning gel composition hereof is that the sprayable cleaning gel composition hereof is intended to be suitable for use on virtually all surfaces, including glass, plastics, vinyls, metals, and painted surfaces. Moreover, if a cleaner containing bleach is spilled on clothing, it may burn holes therein or create unsightly spots thereon. In contrast, the sprayable cleaning gel composition according to the present invention will not stain or damage clothing if spilled thereon.
Unless otherwise noted, all component percentages in this discussion are by weight of the sprayable cleaning gel composition.
In a preferred embodiment of the present invention, the sprayable cleaning gel composition 20 comprises: from about 75% to about 98% of a liquid carrier; from about 0.005% to about 20% of a surfactant selected from the group consisting of nonionic, anionic, cationic, amphoteric, and zwitterionic surfactants and mixtures of the above; and from about 0.01% to about 10% of a water-soluble polymeric thickening agent; wherein the sprayable cleaning gel composition has a viscosity from about 900 centipoise (cP) to about 5,550 cP at standard temperature and pressure (25 degrees Centigrade and 1 atmosphere of pressure).
In a further preferred embodiment of the present invention, the sprayable cleaning gel composition hereof further comprises: from about 1% to about 20% of at least one supplemental solvent for dissolving oil-based particles in water; and from about 0.001% to about 5% of a dispersant; wherein the thickening agent is a polyacrylic acid thickener.
In yet a further preferred embodiment of the present invention, the sprayable cleaning gel composition 20 hereof further comprises from about 0.05% to about 0.50% of an anti-static agent.
The sprayable cleaning gel composition according to the preferred embodiments hereof may, optionally, include additional adjuvants such as a fragrance, a base, an organic acid, a chelant such as sodium EDTA, or a colorant.
Components of the Sprayable Cleaning Gel Composition
Liquid Carrier
The sprayable cleaning gel composition according to the present invention includes a liquid carrier as a primary solvent. The carrier fluid may be water, alcohol, or mixtures thereof. Where alcohols are used in the liquid carrier, preferred alcohols include isopropyl alcohol, methanol, tert-butyl alcohol, and mixtures thereof. Water is considered to be a preferred carrier fluid in this formulation. The liquid carrier is present in a range from about 75% to about 98% of the composition, preferably in a range from about 85% to about 98% of the composition, and most preferably in a range from about 90% to about 97% of the composition.
Too much liquid carrier may result in spotting and/or unacceptably low viscosity; and too little liquid carrier could result in filming or in difficulty wiping away the sprayable cleaning gel composition from the surface being cleaned.
Surfactant
In order to boost the cleaning power of the sprayable cleaning gel composition hereof, a surfactant component comprising at least one surfactant is present in the composition hereof in a range from about 0.005% to about 20% of the composition, preferably from about 0.005% to about 15% of the composition, and most preferably from about 0.01% to about 10% of the composition.
Surfactants are generally well-known in the detergent art. Surfactants which are usable in the practice of the present invention include anionic, nonionic, cationic, amphoteric, zwitterionic, and mixtures of the above types.
1. Anionic Surfactants:
Anionic synthetic detergents can be broadly described as surface active agents with one or more negatively charged functional groups. Anionic surfactants are discussed at some length in U.S. Pat. No. 3,929,678 to Laughlin et.al, issued Dec. 30, 1975 at column 23, line 58 through column 29, line 23, herein incorporated by reference. Soaps are included within the category of anionic surfactants. A soap is a C8 -C22 alkyl fatty acid salt of an alkali metal, alkaline earth metal, ammonium; alkyl substituted ammonium or alkanolammonium. Sodium salts of tallow and coconut fatty acids, and mixtures thereof, are most common.
Another important class of anionic compounds is the water-soluble salts, particularly the alkali metal salts, of organic sulfur reaction products having in their molecular structure an alkyl radical containing from about 8 to 22 carbon atoms and a radical selected from the group consisting of sulfonic acid and sulfuric acid ester radicals. Organic sulfur-based anionic surfactants include the salts of C10 -C14 alkylbenzene sulfonates, C10 -C22 alkene sulfonates, C10 -C22 alkyl ether sulfonates, C10 -C22 alkyl sulfates, C4 -C10 dialkyl sulfosuccinates, C10 -C22 acyl methionates, alkyl diphenyloxide sulfonates, alkyl naphthalene sulfonates, and 2-acetamido hexadecane sulfonates. Also included are nonionic alkoxylates having a sodium alkylene carboxylate moiety linked to a terminal hydroxyl group of the nonionic alkoxylate through an ether bond. Counter-ions to the salts of all the foregoing may be those of alkali metal, alkaline earth metal, ammonium; alkanolammoninm and alkylammonium types. Anionic surfactants which are water-soluble alkylbenzene sulfonate salts of organic sulfur-reaction products are described in U.S. Pat. Nos. 2,220,099 and 2,477,383, herein incorporated by reference. Especially valuable are linear straight-chain alkylbenzene sulfonates in which the average number of carbon atoms in the alkyl group is from about 11 to 13, abbreviated as C11 -C13 LAS. Preferred anionic surfactants of this type are the alkyl polyethoxylate sulfates, particularly those in which the alkyl group contains from about 10 to about 22, preferably from about 12 to about 18 carbon atoms, and wherein the polyethoxylate chain contains from about 1 to about 15 ethoxylate moieties, preferably from about 1 to about 3 ethoxylate moities.
Other anionic surfactants of this type include sodium alkyl glyceryl ether sulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil, sodium coconut oil fatty acid monoglyceride sulfonates and sulfates, sodium or potassium salts of alkyl phenol ethylene oxide ether sulfates containing from about 1 to about 10 units of ethylene oxide per molecule and wherein the alkyl group contains from about 8 to about 12 carbon atoms, and sodium or potassium salts of alkyl ethylene oxide ether sulfates containing about 1 to about 10 units of ethylene oxide per molecule and wherein the alkyl group contains from about 10 to about 20 carbon atoms.
Also included are water-soluble salts of esters of alpha-sulfonated fatty acids containing from about 6 to 20 carbon atoms in the fatty acid group and from about 1 to 10 carbon atoms in the ester group, water-soluble salts of 2-acyloxy-alkane-1-sulfonic acids containing from about 2 to 9 carbon atoms in the acyl group and from about 9 to about 23 carbon atoms in the alkane moiety, alkyl ether sulfonates containing from about 10 to about 20 carbon atoms in the alkyl group and from about 1 to about 30 moles of ethylene oxide; water-soluble salts of olefin sulfonates containing from about 12 to 24 carbon atoms; and beta-alkoxy alkane sulfonates containing from about 1 to 3 carbon atoms in the alkyl group and from about 8 to 20 carbon atoms in the alkane moiety.
Another class of usable anionic surfactants is the N-alkyl substituted succinates.
2. Nonionic Surfactants:
Nonionic surfactants may be broadly defined as compounds produced by the condensation of alkylene oxide groups with an organic hydrophobic material, which may be aliphatic or alkyl aromatic in nature. The length of the hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements. Some nonionic surfactants are discussed in U.S. Pat. No. 3,929,678 to Laughlin et. al., issued Dec. 30, 1975, at column 13, line 14 through column 16, line 6, herein incorporated by reference.
Illustrative, but not limiting, examples of various suitable nonionic surfactant types are:
(a) polyoxyethylene or polyoxypropylene condensates of aliphatic carboxylic acids, whether linear or branched-chain and saturated or unsaturated, containing from about 8 to about 18 carbon atoms in the aliphatic chain and incorporating from about 5 to about 50 ethylene oxide and/or propylene oxide units. Suitable carboxylic acids include "coconut" fatty acids (derived from coconut oil) which contain an average of about 12 carbon atoms, "tallow" fatty acids (derived from tallow-class fats) which contain an average of about 18 carbon atoms, palmitic acid, myristic acid, stearic acid, and lactic acid.
(b) polyoxyethylene or polyoxypropylene condensates of aliphatic alcohols, whether linear or branched-chain and saturated or unsaturated, containing from about 6 to about 24 carbon atoms and incorporating from about 5 to about 50 ethylene oxide and/or propylene oxide units. Suitable alcohols include "coconut" fatty alcohol "tallow" fatty alcohol, lauryl alcohol, myristyl alcohol and oleyl alcohol.
(c) polyoxyethylene or polyoxypropylene condensates of alkyl phenols. These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to 12 carbon atoms in either a straight chain or branched configuration with ethylene and/or propylene oxide, the ethylene and/or propylene oxide being present as about 5 to 25 moles of ethylene and/or propylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds can be derived, for example, from polymerized propylene, diisobutylene, and the like. Examples of compounds of this type include nonyl phenol condensed with about 9.5 moles of ethylene oxide per mole of phenol; dinonyl phenol condensed with about 12 moles of ethylene oxide per mole of phenol; dinonyl phenol condensed with about 15 moles of ethylene oxide per mole of phenol; and diisooctyl phenol condensed with about 15 moles of ethylene oxide per mole of phenol. Commercially available nonionic surfactants of this type include "IGEPAL CO-630", marketed by the GAF Corporation of Wayne, N.J., and "TRITON X-45, X-114, X-100, and X-102", all marketed by the Rohm and Haas Company of Philadelphia, PA. Preferred nonionic surfactants in this category are water-soluble surfactants sold by Rohm and Haas Company under the trademark "TRITON". TRITON X-100, which is an octylphenoxypolyethoxyethanol containing an average of 10 moles of ethylene oxide, is particularly preferred for use in the sprayable cleaning gel composition according to the present invention.
3. Cationic Surfactants
Cationic surfactants may also be used in the sprayable cleaning gel composition according to the present invention. However, when the preferred polyacrylic acid thickener is used, cationic surfactants must be, if used, of high molecular weight; anionic or nonionic surfactants are preferred. Suitable cationic surfactants include quaternary ammonium surfactants having the formula:
�R1 (OR2)y !�R3 (OR2)y !R4 N+ X-
wherein R2 is an alkyl or alkyl benzyl group having from about 8 to about 18 carbon atoms in the alkyl chain; each R2 is selected from the group consisting of --CH2 CH2 --, --CH2 CH(CH3)--, --CH2 CH (CH2 OH)--, --CH2 CH2 CH2 --, and mixtures thereof; each R3 is selected from the group consisting of C1 -C4 hydroxyalkyl, benzyl, ring structures formed by joining the two R3 groups, --CH2 CHOHCHOHCOR5 CHOHCH2 OH-- wherein R5 is any hexose or hexose polymer having a molecular weight less than about 1000, and hydrogen when y is not 0; R4 is the same as R3 or is an alkyl chain wherein the total number of carbon atoms of R1 plus R4 is not more than about 18; each y is from about 0 to about 10 and the sum of the y values is from 0 to about 15; and X is any compatible anion.
4. Other Surfactants
Amphoteric surfactants, also called ampholytic surfactants, may be broadly defined as aliphatic derivatives of secondary or tertiary amines, or aliphatic derivatives of heterocyclic secondary and tertiary amines in which the aliphatic radical can be straight chain or branched, and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and at least one contains an anionic water-solubilizing group, e.g. carboxy, surfate, or sulfonate. See U.S. Pat. No. 3,929,678 to Laughlin et. al., issued Dec. 30, 1975 at column 19, lines 18-35 (herein incorporated by reference) for examples of amphoteric surfactants.
Zwitterionic surfactants may be broadly described as derivatives of secondary and tertiary amines, derivatives of heterocyclic secondary and tertiary amines, or derivatives of quaternary ammonium, quaternary phosphonium, or tertiary sulfonium compounds.
Thickening Agent (Thickener)
The sprayable cleaning gel composition according to the present invention has a preferred viscosity in the range of about 900 cP to about 5,550 cP at standard temperature and pressure (25 degrees Centigrade and 1 atmosphere pressure), preferably from about 1,500 cP to about 4,500 cP and most preferably from about 2,700 cP to about 3,000 cP. In order to achieve the target viscosity, the addition of a thickening agent (thickener) is required, in an amount sufficient to give the composition the consistency of a gel with a viscosity in the preferred range. Generally in this regard, the thickening agent should be present in a range from about 0.01% to about 10% of the composition. Suitable thickening agents include polyacrylic acid polymers in a range from about 0.01% to about 2% of the composition, preferably in a range from about 0.05% to about 1% of the composition, and more preferably in a range from about 0.1% to about 0.5% of the composition, and most preferably about 0.2% of the composition.
While many thickening agents are known for increasing fluid viscosity, the preferred polyacrylic acid polymers exhibit a surprising and unexpected tendency to allow free flow under pressure for good sprayability of the sprayable cleaning gel composition, yet to prevent downward flow due to gravity once the sprayable cleaning gel composition is in place on a surface to be cleaned.
The preferred thickener for use in formulating the sprayable cleaning gel composition according to the present invention is a polyacrylic acid powder. A family of commercially available crosslinked polyacrylic acid powders which are suitable for use in the practice of the present invention is sold by B.F. Goodrich Specialty Chemicals of Cleveland, Ohio, under the name "CARBOPOL". The product CARBOPOL EZ-1, which has a molecular weight of about 4,000,000, is particularly suited for use in formulating the sprayable cleaning gel composition hereof.
Brookfield yield value is defined as the minimum shear stress required to initiate flow in a non-Newtonian fluid. Preferably, the thickening agent used in the practice of the present invention will be one which has a Brookfield yield value in a range from about 16 to about 140, more preferably from about 40 to about 120, and most preferably from about 80 to about 120. A high yield Brookfield value indicates that the minimum shear stress required to initiate flow will be greater than that effected by the force of gravity, thus allowing the sprayable cleaning gel composition to non-runningly cling to (ie., dwell on) the surface onto which it has been sprayed, rather than running downwardly or dripping.
The thickening agent provides a moisture residue on a surface that has been sprayed with the sprayable cleaning gel composition and then wiped clean by a wiping article. This moisture residue causes the tendency of the surface to acquire a static electric charge due to wiping to be noticeably minimized. This feature is important as the static electric charge tends to be greatest immediately after wiping a surface, and static electric charge tends to cause dust to accumulate on the surface. Therefore, by minimizing the static electric charge, the surface will appear cleaner for a longer time than would be expected for surface cleaners not including a thickening agent.
Supplemental Solvent
A supplemental solvent is, optionally, included as a component of the present invention to help dissolve oil-based materials in the water-based sprayable cleaning gel composition 20, whether those oil-based materials are part of the sprayable cleaning gel composition such as, e.g., oil-based fragrances, or whether the oil-based material is a soil to be cleaned off of a surface. Where used, the supplemental solvent is present in an amount ranging from about 1% to about 20% of the composition, preferably from about 2% to about 8% of the composition, and most preferably from about 2% to about 6% of the composition. Glycol ethers are a preferred class of supplemental solvents in the practice of the present invention. Usable glycol ethers include propylene glycol methyl ether (CAS No. 107-98-2), dipropylene glycol methyl ether (CAS No. 34590-94-8), ethylene glycol n-butyl ether MSDS (CAS No. 111-76-2), and propylene glycol t-butyl ether (CAS No. 57018-52-7)
,
which is the most preferred supplemental solvent for use in the practice
of the present invention. Dispersant
In order to promote homogeneous distribution of the mixture components in the sprayable cleaning gel composition and to break up and disperse soils in application of the sprayable cleaning gel composition, in a preferred embodiment of the present invention, a dispersant may, optionally, be included in the sprayable cleaning gel composition. Polycarboxylates are preferred dispersants in the practice of the present invention in an amount ranging from about 0.005% to about 5% of the composition, preferably from about 0.01% to about 1% of the composition, and most preferably from about 0.05% to about 0.5% of the composition. Suitable polycarboxylates include carboxylic acid-olefin copolymers and carboxylic acid-vinyl ether copolymers sold by BASF Specialty Products of Parsippany, N.J. under the name "SOKOLAN". In particular, SOKOLAN CP-9, a sodium salt of a maleic acid-olefin copolymer, has been found useful in the practice of the present invention. Other dispersants which may be used are acrylic detergent polymers.
Base
Addition of a base to the sprayable cleaning gel composition may be used to raise the pH of the composition to a value from about 5 to about 11.5 in order to uncoil the polymeric molecules of the thickener and precipitate gelatinous thickening of the composition. Alternatively, ammonia may be used as a component of the sprayable cleaning gel composition to contribute to cleaning effectiveness. Adding a base may not be necessary if alcohol is present in the liquid carrier or if an organic acid is present in the sprayable cleaning gel composition because these components will also precipitate thickening of the mixture if used in sufficient quantity. Where used, sufficient base should be added to adjust the pH to the desired level of between about 5 and 11.5. Suitable bases include sodium hydroxide, ammonium hydroxide, morpholine, and amines such as, e.g., triethanolamine.
Organic Acids
In some formulations of the sprayable cleaning gel composition according to the present invention, one or more organic acids may optionally be added to the sprayable cleaning gel composition as a cleaning aid. Preferred organic acids are acetic acid, citric acid, and mixtures thereof. Where present, organic acids are used in a range from about 1% to about 5% of the composition. It is preferred that organic acids not be used together with ammonia.
Anti-Static Agent
The sprayable cleaning gel composition 20 according to the present invention advantageously may include an agent which enhances the innate anti-static feature of the thickening agent, as discussed hereinabove, by actively preventing static electric charge build-up on a surface while the sprayable cleaning gel composition is being wiped therefrom, as well as for a period of time thereafter. Where present, the anti-static agent is used in a range of from about 0.05% to about 1.0% of the composition, preferably about 0.2% of the composition. An example of a suitable anti-static agent therefor is Eccostat 501 manufactured by Eastern Color & Chemical Co. of Providence, R.I. Eccostat 501 is a nonionic ester complex. Because the anti-static feature of the thickening agent tends to decrease over time (in about a day or so), the inclusion of an anti-static agent provides long term (on the order of weeks or longer) prevention of static electric charge build-up on a surface upon which the sprayable cleaning gel composition 20 containing the antistatic agent has been wiped thereoff. Accordingly, with inclusion of the anti-static agent, the surface will appear cleaner, both at the time of cleaning and for a long time thereafter. Interestingly, the ability of the anti-static agent to prevent build-up of static electric charge during wiping of the surface being cleaned is most effective for plastic surfaces, which would otherwise tend to readily develop a static electric charge upon being wiped.
It has been discovered that an excellent anti-static agent is a nonionic water soluble silicone based lubricant and softener, which, it has been found in testing, not only improves surface wiping, as is expected; but, in addition to providing surfactant properties, also unexpectedly provides exceptional anti-static properties. An example of a nonionic water soluble silicone based lubricant and softener of this class is Eccolube RT-5-8 of Eastern Color & Chemical Co. of Providence, R.I. Eccolube RT-5-8 is sold by its manufacturer for use as a lubricating and softening agent.
In tests performed at substantially standard temperature and pressure with Eccolube RT-5-8 as the anti-static agent in the sprayable cleaning gel composition, the following results were obtained: at about 0.50% of the composition, excellent anti-static properties were observed, and with respect to wiping the sprayable cleaning gel composition off a surface, slight smearing, no hazing and very low resistance to wiping were observed; at about 0.30% of the composition, excellent anti-static properties were observed, and with respect to wiping the sprayable cleaning gel composition off a surface, no smearing, no hazing, smooth finish and very low resistance to wiping were observed; at about 0.20% of the composition, excellent anti-static properties were observed, and with respect to wiping the sprayable cleaning gel composition off a surface, no smearing, no hazing, smooth finish and very low resistance to wiping were observed; at about 0.10% of the composition, unpredictably excellent or poor anti-static properties were at times observed; and at about 0.05% of the composition, poor anti-static properties were observed and fair wiping characteristics were observed. It is to be understood that while the preferred lower limit of about 0.05% of the sprayable cleaning gel composition 20 could be lower, the preferred lower limit is based upon increasing poorness of the anti-static properties, and that while the preferred upper limit of about 0.50% of the sprayable cleaning gel composition could be higher, the preferred upper limit is based upon increasing poorness of wiping characteristics (such as for example smearing), as well as cost effectiveness.
Other Adjuvants
Other adjuvants such as fragrances, dyes, a chelant such as EDTA, or additional ingredients may, optionally, be added to the sprayable cleaning gel composition hereof, so long as they are compatible with stable storage life of the composition.
