Definitions
- the invention relates to aqueous alkaline cleaners that can be used to remove stubborn soils from food preparation units, and aqueous acidic cleaners that are used to remove soils from hard surfaces such as floors and walls.
- the invention relates to aqueous alkaline materials that can be applied, in the form of an aerosol or pump spray, onto stubborn soils present in food preparation units such as gas or electrically heated ovens, microwave ovens, toaster ovens, etc.
- oven includes ovens, deep fryers, grills and hoods.
- Acidic and alkaline cleaning compositions for hard surfaces have been used for many years to remove stubborn soils from a variety of surfaces found in household and institutional locations.
- soils include inorganic soils and soils derived from organic sources, such as fats, oils, proteins and carbohydrates, which can form hard tenacious deposits on a variety of surfaces including ceramic, stainless steel, concrete, tile and metal food preparation surfaces.
- Typical inorganic solids comprise insoluble materials derived from the hardness components of service water including substantially insoluble salts of calcium, magnesium, iron, manganese, etc. Such inorganic salts can be combined in some cases with organic residues which can form large, difficult to remove soil deposits.
- These soils can be unsightly, can take the form of large deposits of charred or baked-on residue, or large areas of white insoluble soap scum or hardness deposits. These soils can also promote or support the growth of microorganisms that can under certain circumstances contaminate food or other contaminatable materials or surfaces.
- cleaners A variety of cleaning compositions have been developed to deal with the tenacious organic and organic/inorganic matrix soils common in a variety of surfaces.
- One particularly useful form of cleaner is an aqueous alkaline cleaner commonly delivered from a pressurized aerosol or pump spray device. These types of cleaners have great utility for a variety of surfaces because the material can be delivered by spray to vertical, overhead or inclined surfaces or to surfaces having a complex curved or convoluted surface while achieving substantially complete coverage of the surface with the spray-on liquid cleaner.
- Acid spray-on cleaners are also known for removing basic inorganic soils and are becoming more common.
- One substantial problem that arises with such spray-on materials relates to an airborne mist or finely divided aerosol generated during the spraying process.
- the aqueous liquid is converted by the action of propellant or pump action into a spray that is accompanied by a finely divided aerosol or mist.
- the spray portion contacts and remains on the target surface, while a substantial proportion of the aerosol can remain suspended in the atmosphere.
- Such aqueous compositions having a strong acid or strong base cleaning component in the form of a finely divided aerosol or mist can cause respiratory distress in the user.
- a very strong and irrepressible choking response is seen in most individuals that come in contact with irritating proportions of the aerosol produced by typical spray-on cleaners.
- the choking response is inconvenient, reduces cleaning efficiency in a variety of applications and in sensitive individuals can cause asthma attacks, respiratory damage, or other discomfort or injury.

- Flannery United Kingdom Patent No. 2,019,876, teaches an aerosol comprising sodium bicarbonate as an oven cleaner.
- aqueous strong acid or aqueous strong base cleaning compositions that are used in a spray-on format can be made non-choking by producing a formulation that when sprayed results in the creation of an airborne aerosol or mist having a mean particle size greater than about 170 ⁇ , preferably greater than about 200 ⁇ m.
- the materials of the invention produce little or no small particle aerosol.
- the concentration of small particle airborne aerosol from a mean particle size greater than 200 ⁇ m is not sufficient to cause respiration difficulty.
- Aerosol sprays either propellant driven or pump driven, create a spray pattern of the aqueous liquid that contacts the target surface.
- Some spray nozzles produce a greater proportion of small particle airborne aerosol than others.
- the major proportion of the liquid resides in large sprayed deposits which contact and remain on a target surface.
- a small proportion becomes an airborne aerosol or mist.
- the mist or aerosol particle size discussed above, relates to the mist created during the spray action and is not directed to the material sprayed which remains in contact with the target surface.
- Any spray pattern created during spraying operations will contain an array of large and small spray particles which do not become airborne and are transported directly to and remain in place on the treated surface. We are not concerned with the proportion of the spray that remain on the target surface.
- the improved compositions of the invention comprise aqueous materials comprising a strong acid or a strong base, an organic surfactant, an organic polymeric thickener, and a variety of other useful optional ingredients.

- the materials are typically applied to hard surfaces containing difficult inorganic, organic, or matrix-blended soils.
- soils include baked-on or carbonized food residues.
- Other surfaces can contain soils derived from substantially insoluble hardness components of service water.
- the enhanced cleaning compositions of the invention rapidly remove such soils because the cleaners have a unique combination of cleaning ingredients combined with thickeners that can rapidly remove the soils but resist formation of an amount of mist or aerosol during application that can cause respiratory distress.
- the terms "aerosol” and “mist” refer to airborne dispersions of small particles comprising the cleaning composition that can remain suspended or dispersed in the atmosphere surrounding a cleaning site for at least 5 seconds, more commonly 30 seconds to 10 minutes.
- any sprayable composition can be rendered at worse, mildly irritating if the mean particle size of its aerosol or mist created upon spraying is maintained at greater than 200 ⁇ m, preferably greater than 210 ⁇ m.
- the sprayable aqueous cleaning compositions of the invention typically comprise either a strong acid or strong base in combination with an organic surfactant, and an effective organic thickener material in an aqueous composition.
- the compositions of the invention can contain a variety of other optional ingredients recited below.

- a source of alkalinity also known as a basic material is a composition that can be added to an aqueous system and result in a pH greater than about 7.
- Organic sources of alkalinity are often strong nitrogen bases including, for example, ammonia, monoethanol amine, monopropanol amine, diethanol amine, dipropanol amine, triethanol amine, tripropanol amine, etc.
- One value of using the monoalkanol amine compounds relates to the solvent nature of the liquid amines.
- the source of alkalinity can also comprise an inorganic alkali.
- the inorganic alkali content of the spray-on cleaners of the invention is preferably derived from sodium or potassium hydroxide which can be used in both liquid (about 10-60 wt% aqueous solution) or in solid (powder, flake or pellet) form.

Such nonionic surfactants typically comprise molecules containing large segments of a polyoxyethylene group in conjunction with a hydrophobic moiety or a compound comprising a polyoxypropylene and polyoxyethylene segment. Polyoxyethylene surfactants are commonly manufactured through base catalyzed ethoxylation of aliphatic alcohols, alkyl phenols and fatty acids. Polyoxyethylene block copolymers typically comprise molecules having large segments of ethylene oxide coupled with large segments of propylene oxide. These nonionic surfactants are well known for use in this art area.
- the lipophilic moieties and cationic groups comprising amino or quaternary nitrogen groups can provide surfactant properties to surfactant molecules.

- the solvent capacity of the cleaners can be augmented by using monoalkanol amines.
- compositions of the invention require the presence of a material that will provide a composition that is thixotropic, in other words the material when left undisturbed (in a shear mode), retains a high viscosity. However, when sheared, the viscosity of the material is substantially but reversibly reduced. After the shear action is removed, the viscosity returns. These properties permit the application of the material through a spray head. When sprayed from an aerosol container using a propellant, the material undergoes shear as it is drawn up a feed tube into a aerosol spray head under the influence of the pressure of a propellant or is sheared by the action of a pump in a pump action sprayer.
- the viscosity must drop to a point such that substantial quantities of the material can be applied using the spray devices used to apply the material to a soiled surface.
- the materials should regain high viscosity to ensure that the material remains in place on the soil.
- the material can be applied to a surface resulting in a substantial coating of the material that provides the cleaning components in sufficient concentration to result in lifting and removal of the hardened or baked-on soil. While in contact with the soil on vertical or inclined surfaces, the thickeners in conjunction with the other components of the cleaner prevent dripping, slumping or other movement of the material under the effects of gravity.

It has little corrosive action on common surface materials and is low in cost compared to other water conditioners.
- Sodium tripolyphosphate has relatively low solubility in water (about 14 wt-%) and its concentration must be increased using means other than solubility.
- Typical examples of such phosphates being alkaline condensed phosphates (i.e. polyphosphates) such as sodium or potassium pyrophosphate, sodium or potassium tripolyphosphate, sodium or potassium hexametaphosphate, etc.
- compositions of the invention can contain a material that can protect metal from corrosion.
- metal protectors include for example sodium gluconate and sodium glucoheptonate.
- adjuvant materials for hard surface cleaning.
- adjuvant materials may include foam enhancing agents, foam suppressing agents (when desired), preservatives, antioxidants, pH adjusting agents, perfumes, colorants, or pacifying or pearlescent agents, builder salts, cosolvents and other useful well understood material adjuvants.
- foam enhancing agents foam suppressing agents (when desired), preservatives, antioxidants, pH adjusting agents, perfumes, colorants, or pacifying or pearlescent agents, builder salts, cosolvents and other useful well understood material adjuvants.
- foam suppressing agents when desired
- preservatives antioxidants
- pH adjusting agents pH adjusting agents
- perfumes colorants
- pacifying or pearlescent agents builder salts
- cosolvents cosolvents and other useful well understood material adjuvants.
- the materials of the invention are commonly applied to soiled surfaces using a pressurized aerosol or aerosol pump spray. In pressurized aerosol application, the compositions of the invention are combined with a
- Typical propellants include lower alkanes such as propane, butane, nitrous oxide, carbon dioxide, and a variety of fluorocarbons.
- Pressurized aerosol containers typically include a spray head, valve and dip tube that reaches to the opposite end of the container to ensure that the entire contents of the container is dispensed through the action of the propellant. When the valve is opened (depressed), the propellant pressure forces liquid into the dip tube and through the aerosol spray head. At the spray head exit, a spray pattern is created by the geometry of the aerosol valve which directs the material onto the soiled surface. Aerosol containers, dip tubes, propellants and spray valves are well understood commercial technology. Pump spray devices commonly comprise a container spray head valve pump and dip tube.
- Actuating the pump causes a piston to travel in a cylinder filled with compositions of the invention.
- the piston motion forces the composition through an aerosol valve causing the spray to adhere to a soiled surface.
- the piston is returned by a spring action to its original position causing the cylinder to fill with additional quantities of the spray material through a valve opening.
- the valve closes preventing the exit of any of the solution from the cylinder.
- the pump spray can deliver substantial quantities of the material onto the soiled surface.
- the materials of the invention can be made by combining the ingredients in an aqueous diluent using commonly available containers and blending apparatus.
- a preferred method for performing the composition of the invention includes introducing into a stirred production vessel, a quantity of the deionized water followed by the organic thickener material used to provide thixotropic properties to the compositions of the invention. After the thickener is fully solubilized, the other ingredients of the invention can be added in any order.
- This test is meant to simulate a cleaner's ability to remove polymerized oils from institutional hoods, ovens, and grills.
- a 2.5 gram sample of Mazola brand corn oil is spread evenly onto a 14 inch by 14 inch sheet of stainless steal. The sheet is heated at 200°C for three hours. The heating procedure causes the oil to polymerize to a tenacious varnish-like yellow film.
- a composition's cleaning ability is measured relative to a standard formulation. One gram samples of the test formulation and the standard are placed onto the polymerized film using a dropper. This is done at room temperature. The time required for the composition sto cause the film to loosen is recorded. By loosen is meant that the film wrinkles and lifts from the stainless steel surface to the point where it is removed by running tap water over the sheet.
- This test is meant to simulate a cleaner's ability to remove freshly deposited, non-polymerized oils and greases from hard surfaces found in institutional kitchens.
- a one gram sample of Crisco brand all-vegetable shortening is spread evenly onto a 10 inch by 10 inch glass door of a laboratory hood.
- a composition's cleaning ability is measured relative to a standard formulation.
- a test formulation is sprayed onto the soil through an Affa Sprayer No. 5910BA. Five sprays are used in a "domino" pattern. After the fifth spray, the composition is allowed to remain in contact with the soil for one minute before wiping.
- a Scott brand laboratory Soft Cote Wipe is used to wipe off the soil. Following the wipe, one additional spray is applied t othe surface and a new wipe is used to, again, wipe the surface.
- the efficacy of the cleaner is measured during the one minute after the initial spray and after each wiping.
- a satisfactory test formulation emulsifies and lifts the soil during the one minute, and leaves a grease free surface after wiping. In particular, the surface should be clean and streak free after the second wipe.
- Example 1 The composition of Example 1 was tested for its ability to clean common greasy soil. A 10 inch x 10 inch area of glass was coated with 1 gram of Crisco brand shortening. Formula I was diluted to 50 wt% and was sprayed on such 10 inch x 10 inch sample of grease. The 50 wt% diluted concentration cut the grease cleanly.
- Example 2B A test of the Example 2B at a 50 wt% active dilution in water resulted in a 100% cleaning of the Crisco test sample.
- Particle size analysis test formulations were dispensed through an aerosol misting sprayer (Affa Sprayer No. 5910BA) into a Malvern Instruments Particle Sizer model INDP.
- test formulations were evaluated by spraying the test formulations into a laboratory sink with the same aerosol misting sprayer as used for the particle size analysis and having the person doing the spraying inhale the air over the sink and record the level of irritation on a 0-5 scale with 0 being no irritation and 5 being very irritating.
- Formula 3A 3B 3C Water to 100% to 100% to 100% KELZAN AR 0.2 0.2
- the level of irritation for formula 3A is rated as a 1. This is not complete elimination of irritation, but a significant reduction. Compared to a similar formula (3C) made without thickener a substantial improvement has been achieved. Likewise the level of irritation for the formula (3B) made with KELZAN AR but without surfactants is also 1. The formulation (3C) without KELZAN AR but with surfactants is rated at an irritation level of 5. The surface tension results do not appear to correlate with the level of irritation. Formula (3C) has a low surface tension but is very irritating, while formula (3A) has a similar surface tension but shows a greatly reduced level of irritation. Formula 3B is low in irritation but has increased surface tension. The level of irritation does correlate to particle size.
- Highly irritating formulation 3C has a mean particle size of 107.9 micrometers, while the two reduced irritation formulas have a larger mean particle size of 206.5 and 212.1 micrometers.
- KELZAN AR holds the water droplets together and mitigates the fine mist that gets into the air and causes the irritation.
- Formula 4A 4B 4C 4D Water to 100% to 100% to 100% to 100% to 100%
- Phosphoric acid (75%) 1 . 625 11. 625 11 . 625 11. 625 Citric acid (50%) 4 . 875 4 . 875 4 . 875 4 . 875 Butyl carbitol 4 . 000 4 . 000 4 . 000 4 . 000
- the cleaning compositions of the invention which include a highly alkaline material or a highly acid material as an active cleaning component in conjunction with other cleaning ingredients in a thickened aqueous material provides excellent soil removal properties.
- the irritating effects of mists or aerosols generated using the compositions of the invention in a spray device can be substantially removed if the material sprayed results in a mean particle size that is greater than 200 ⁇ m.
- the thickened materials of the invention do not lose any cleaning capacity once formulated to produce a low particle size aerosol or mist.
