The present invention relates to a new and improved composition for and method of quickly and? expeditiously removing and cleaning from a surface, such as the interior surface'of acooking oven, all adherent residue of burnt-on fat or other deposits of greasyor oily character;
Among the principaliobjects of the'p'resent invention is the provisioniofa cleanser composition'whichmay be contained in and dispensed from a pressure-tight. container having; a conventional aerosol dispensing valve, said'concentrate being characterized by the fact that it is in the form of a concentrate which includes, inter alia, an aqueous solutionof caustic alkali-which is noncorrosive and so produces no harmful effects on theskin should any of the concentrate contact the skin during use of the cleansing composition. Theconcentrate is dispensed from the aerosol package by a propellant contained therein, which propellant is completely inert with respect to and substantially insoluble in the concentrate. Instead the propellant forms with the concentrate, upon shaking of the package, an emulsion from which the propellant is gradually released tothereby effect upon actuation of the aerosol dispensing valve, discharge of the concentrate from the aerosol package to the surface to-be cleaned. Since thepropellant basically remains not dissolved in the. concentrate, where it is of a specific gravity higher than that of the-concentrate, it is. normally disposedf as a liquid inthe bottom of the. aerosol. containerin underlying relation to the concentrate. However, whenthe aerosol package is vigorously shaken to form the above-mentioned concentrate-propellant emulsion andthe aerosol discharge valve is then opened, a proportion of'the propellant in the form of a vapor is releasedfrom the emulsion into the head space of the container'and maintains therein a gaseouspressure sufficient to expel the emulsion from the container, so that the concentrate, upon its discharge from the container and. impingement upon the surface being cleaned is converted intoafoatn by the expanding action of the gas entrained therein.
ln accordance with the principles of thepresent in vention, the-cleanser concentrate contains as its essential constituents l caustic alkali (whichmay be either sodium: hydroxide or potassiumhydroxide-)';.(2) a nitrogen-containingsurfactant of the anionic class, with or without a fatty acidsoap as afoam stabilizing'agent; (3)- a high boiling, essentially non-evaporative polyhydric alcohol; and (4) water in which the foreging constituents aredissolved to form an aqueous solution thereof.
As has been indicated above, the propellant employed in conjunction with such aqueous solution of concentrate packaged in an aerosol" container is of a kind which not only is neither substantially hydrolyzable or degradable in the presence of the concentrate but also is substantially insoluble therein so that it combines with the-concentrate only in the form. ofan emulsion.
'The caustic alkali employed, either sodium hydroxide or potassium hydroxide, is. readily soluble in water, the proportion of alkali used based on the total: weight of the concentrate ranging from 0.5 to 5 percent as against a water content of from 30 to percent by weight of the concentrate. This exceedingly small ratio of caustic alkali to water in the concentrate provides important advantages for the concentrate of the present invention, among which advantages may be listed the fact that water is the least expensive solvent and so materially reduces the cost of the concentrate, and the fact that the relatively high proportion of water present in the concentrate makes it unnecessary to water down the soiled surface being cleaned as a preliminary to application of the cleanser composition and effective activation thereof.
Another most important object of the present invention is to provide a concentrate in the form of an aqueous solution of caustic alkali combined with alcohols and anionic surfactants which not only very markedly inhibits corrosive action of the caustic on the skin but also is not corrosive to ferrous metals of which aerosol containers are made.
Ordinarily aqueous solutions of caustic alkali, particularly when the ratio of caustic alkali to water is high, are quite corrosive to human skin and upon contact cause burns which are of an irreversible reaction or nature. The addition of surface active agents as generally employed in combination with caustic alkali for increasing its saponifying action upon food residue or other fat material in adherent contact with the surface to be cleaned increases the harmful action of the caustic on the skin.
I' have found that the use of certain nitrogencontaining anionic surfactants combined with polyhydric alcohols in an aqueous solution containing not more than 5 percent of caustic alkali and from 30 to 70 percent of water by weight of the concentrate provides a concentrate which is effective for use in quickly and easilycleaning adherent food residue and soil from the surfaces of cooking ovens, barbecue grilles and other surfaces made of alkali resistant materials, which has no corrosive actionon the skin nor on ferrous metals, which is relatively non-volatile under normal conditions of use and may be safely admixed with various chlorofluoro-carbon base and hydrocarbon propellants and mixtures thereof for use in aerosol containers to yield a non-flammable pressure-expelled cleansing composition, which is compatible with a fatty acid soap when introduced into the concentrate for the production of a stabilized foam, and which may be safely applied to a soiled surface that has been preheated to a temperature of about 200 F. to effectively increase the rate of saponifying reaction of the concentrate upon the carbonized and non-carbonized fats and soil residue desired to be removed from the surface to be cleaned. Further, I have found that in use of the concentrate of the present invention it is not necessary to employ vinegar or any other agent to neutralize the caustic alkali, nor is it necessary thatthe user of the concentrate wear gloves or other protective articles, since the caustic in the concentrate is so inhibited as to have no corrosive effect upon the human skin and mucuous membranes. By concentrate as used herein is meant the aqueous solution of caustic alkali, polyhydric alcohols and anionic surfactants hereinafter specifi'cally described with or without additives and excluding therefrom the propellant.
The anionic surfactants employed in the concentrate of the present invention may be any one or a mixture of the following:

The non-flammable property of the composition containing the hydrocarbon propellant in accordance with the present invention is an important attribute thereof since it is desirable, for most effective cleansing of oven soils, to spray the composition into the oven pre-heated to a temperature of approximately 200 F. This elevated temperature of the surfaces to be cleaned not only potentiates the action of the caustic on the oven soils, but also effects such instant volatilization of the propellant vapors as to enable them to rapidly flash off and be carried away by the hot air convection currents.
All of the above-mentioned propellants are substantially insoluble in the aqueous concentrate, but instead combine there-with to form a liquid emulsion which, upon its discharge from the dispensing container, and impingement against the surface to be cleaned, effectively forms a stabilized blanket of foam over said surface to soften, dissolve and emulsify the burnt on fats and other deposits so that the same may be readily removed by a simple wiping treatment.
When, however, it is desired to use the concentrate of the present invention as a liquid preparation as distinguished from a foam-forming composition, it may be desirable to incorporate in the concentrate, in lieu of the fatty acid soap stabilizer, a thickening agent such as sodium carboxy methyl cellulose (CMC), amylo pectine starch or other compatible additive which is soluble or at least readily dispersable in the concentrate to render it more or less viscous as may be desired so that it may properly blanket and adhere to the surface to be cleaned.
It will be noted from the formulae examples hereinafter set forth that in both the liquid and the foamforming compositions, the percentages by weight of the basic ingredients thereof which act synergistically to maximally inhibit the corrosive action of the caustic alkali upon human skin and mucuous membranes, namely, the caustic alkali combined in aqueous solution with the aforementioned polyhydric alcohols and anionic surfactants, may be varied within the following ranges:
Caustic Alkali 0.5% to 5.0%
Polyhydric Alcohol 20.0% to 40.0%
Maypon SK" 0.3% to 5.0%
Poly peptide No. 37 1.0% to 20.0%
Sodium N-Lauroyl Sarcosinate 0.5% to 5.0%
Water 30.0% to 70.0%
Similarly, the additives incorporated in the concentrate, to wit, the thickening agent in the case of the liquid preparation and the foam stabilizer with or without additional thickening agents in the case of the foamforming preparation, may vary as desired in any amount up to 5 percent in each instance.
As for the propellant, its percentage (also by weight I of the total foam-forming composition packaged in the dispensing container) may vary in amount as may be necessary to provide in the aerosol container the requisite vapor pressure for effecting complete discharge therefrom of the cleanser contained therein and effective foaming thereof. which pressure should be within safe limits for the container in which the cleanser is packaged.
The following examples are illustrative of the present invention and provide compositions which have exceptionally high cleaning power when used to remove food residue and burnt-on fat and grease deposits from the 5 surfaces of ovens and the like. Further, and of equal importance, is the fact that in all of these illustrative compositions, the corrosive effect of the caustic alkali content thereof is inhibited to minimize burns or other irreversible injury to the user upon contact of the composi- 10 tion with the skin.
In all of the following examples, the percentage values are by weight of the entire composition:
