Definitions
- Highly alkaline detergents for foam cleaning contain, as the foaming additive, sodium salts of fatty acid sulfonates, amine oxides, amido alkyl amine Oxides, substitution derivative of imidazoline alkanoic quaternary ammonium hydroxide, and mixtures thereof.
- the foam cleaning compositions of this invention contain, as essential ingredients, from to 90 weight percent sodium hydroxide, from 5 to weight percent sodium tripolyphosphate, from 0 to weight percent trisodium phosphate, from 10 to 30 weight percents soda ash, from 0 to 5 weight percent calcium silicate, and from 4 to 10 weight percent of a foaming additive.
- Suitable foaming additives include sodium salts of fatty acid sulfonates, amine oxides having the formula:
- R and R are alkyl groups having from one to 34 carbons or hydroxy alkyl groups having from two to 34 carbons, and R, is an alkyl group having from six to 32 carbons; amido alkyl amine oxides having the formula:
- acyl radical selected from the group of acyl radicals having from 10 to 16 carbons, and R and R are alkyl radicals having from one to four carbons; amphoteric compounds having the formula:

- This invention also includes foam cleaning solutions containing from 1.5 to 12 weight percent of the above compositions, formed from a premix of the ingredients or by mixing the individual ingredients with water.
- Foam cleaning is effected by pumping high foam cleaning solutions in a mechanical system in which compresed air is mixed with the cleaning solution to produce a stable, copious foam, and applying the foam to a soiled surface.
- the "dry" foam clings to the surface to be cleaned, increases the contact time of the liquid with the soil and prevents rapid drying or run-off of the liquid cleaner, thereby dramatically improving the cleaning.
- Foam cleaning has several advantages. It reduces the amount of solution required for cleaning. It prevens the splashing experienced in spray cleaning. With foam it is possi- 6 ble to apply cleaning solutions into duct work and pipings, and to the underside and poorly accessible parts of machinery and equipment where spray cleaning is impractical. It prevents the irritating vapors of liquid solutions from into the air.
- Foam cleaning has been shown to be eflective for cleaning trucks, tractor trailers, aircraft, factory walls, and ceilings. it is efi'ective for alkaline paint stripping and for other applications of solvent-type paint stripping from large surfaces such as storage tanks, walls and ceilings, aircraft and tractor trailers.
- the foaming additives which can be used in the composition of this invention include sodium salts of fatty acid 10-22 carbons) sulfonates such as fatty acid sulfonates derived from oleic acid, linoleic acid, linolinic acid, eleosteric acid, licanic acid, palmitoleic acid, petroselenic acid, erusic acid and the like.

Suitable foaming additives include sodium salts of fatty acid sulfonates, amine oxides having the formula:
where R and R are alkyl groups having from one to 34 carbons or hydroxy alkyl groups having from two to 34 carbons, and R, is an alkyl group having from six to 32 carbons; amido alkyl amine oxides having the formula:
wherein is an acyl radical selected from the group of acyl radicals having from 10 to 16 carbons, and R and R are alkyl radicals having from one to four carbons; amphoteric compounds having the formula:
wherein R is a hydrocarbon radical having from four to 18 carbons, R, is a hydrocarbon radical having from one to four carbons, R CO is a acyl radical having from one to four carbons, X is H, Na, K, CH COONa, CH,COOK or cn coon, and Y is H, Na or K; and mixtures of two or more of the above foaming additives. This invention also includes foam cleaning solutions containing from 1.5 to 12 weight percent of the above compositions, formed from a premix of the ingredients or by mixing the individual ingredients with water.
Foam cleaning is effected by pumping high foam cleaning solutions in a mechanical system in which compresed air is mixed with the cleaning solution to produce a stable, copious foam, and applying the foam to a soiled surface. The "dry" foam clings to the surface to be cleaned, increases the contact time of the liquid with the soil and prevents rapid drying or run-off of the liquid cleaner, thereby dramatically improving the cleaning. Foam cleaning has several advantages. It reduces the amount of solution required for cleaning. It prevens the splashing experienced in spray cleaning. With foam it is possi- 6 ble to apply cleaning solutions into duct work and pipings, and to the underside and poorly accessible parts of machinery and equipment where spray cleaning is impractical. It prevents the irritating vapors of liquid solutions from into the air.
It also reduces the cost of labor, time and materials. Foam cleaning has been shown to be eflective for cleaning trucks, tractor trailers, aircraft, factory walls, and ceilings. it is efi'ective for alkaline paint stripping and for other applications of solvent-type paint stripping from large surfaces such as storage tanks, walls and ceilings, aircraft and tractor trailers.
One example of a prior industrial foam cleaning procedure is described in US. Pat. No. 3,037,887, the entire disclosure of which is incorporated herein by reference for background information.
Although a wide variety of surface active agents are commercially available, many of them identified as foaming agents, most of them will not provide a high foaming action in highly alkaline solutions which are required for cleaning applications.
It is the object of this invention to provide a foam cleaning composition which has a high foam characteristic even though it is very alkaline. It is another object of this invention to provide aqueous solutions of this highly foamable alkaline cleaning composition.
The foaming additives which can be used in the composition of this invention include sodium salts of fatty acid 10-22 carbons) sulfonates such as fatty acid sulfonates derived from oleic acid, linoleic acid, linolinic acid, eleosteric acid, licanic acid, palmitoleic acid, petroselenic acid, erusic acid and the like. The preferred fatty acid sulfonate is the sodium salt of sulfonated oleic acid.
Amine oxides can also be used as the foaming additive in the composition of this invention. Suitable amine oxides include those having the formula:
wherein R and R are alkyl groups having from one to 34 carbons or hydroxy alkyl groups having from two to 34 carbons, and R is an alkyl group having from six to 32 carbons. Amine oxides of this type are disclosed in U.S. Pat. No. 3,270,060 and include acetyl dimethyl amine oxide, myristyl-cetyl dimethyl amine oxide, myristyl dimethyl amine oxide, stearyl dimethyl amine oxide, bis (2 hydroxyethyl) alkyl amine oxide, and the like.
Other useful foaming additives include amido alkyl amine oxides having the formula:
wherein is an acyl radical selected from the group of acyl radicals having from 10 to 16 carbons, and R and R are alkyl radicals having from one to four carbons. Foaming agents of this type are disclosed in Canadian Pat. No. 724,663 and include compounds wherein the acyl group is derived from capric, undecanoic, tridecanoic, myristic, pentadecanoic, and palmitic acids, for example.
Highly efi'ective foaming additives which can be used in the composition of this invention include amphoteric compounds having the formula:
wherein R is a hydrocarbon radical having from four to 18 carbons, R is a hydrocarbon radical having from one to four carbons, R CO is an acyl radical having from one to four carbons, X is Na, K, H, CH COONa, CH COOK or lOlO39 CH,COOH; and Y is H, Na, or K. Amphoteric foaming additives of this type are disclosed in U.S. Pat. Nos. 2,528,378 and 2,773,068. The preferred amphoteric foaming agents are those according to the formula wherein R, has 8 carbons and R, and R CO each have two carbons; and those compounds according to the formula where R has 11 carbons, R and R CO each have two carbons, and X and Y are Na, K, or H.
The foaming additives are mixed with alkali metal (preferably sodium) hydroxides, pyrophosphates, tripolyphosphates, orthophophates, carbonates, silicates, and metasilicates to form compositions of these components having the concentration ranges shown in Table A. 7
Aqueous solutions containing from 1.5 to 12 and preferably from 3 to 8 weight percent of these compositions are highly effective foam cleaning compositions. The aqueous solutions can be made by mixing water with a previous mix of the foaming additive together with the other ingredients, or it can be formed by sequential addition of the individual ingredients or combinations of ingredients to water.
For cleaning with aqueous solutions of this invention, the solution is mixed with sufficient air to form a dry" foam in a foaming device such as described in copending application Ser. No. 534,378 filed Mar. 15, 1966, and is applied to the surface to be cleaned.
This invention is further illustrated by the following specific but non-limiting examples.
Dry powder compositions containing 60 percent sodium hydroxide, percent tetrasodium pyrophosphate, 5 percent sodium tripolyphosphate, 2 percent calcium silicate, 13 percent sodium metasilicate, and 4, 6, and percent concentrations of each of the foaming additives shown in Table B were formulated. These compositions are dry, stable powder compositions. Solutions of these compositions in concentrations of from 1.5 to 12 percent produce a dry and copious foam when mixed with air.
Aqueous solutions of these dry powder mixtures are mixed with water in amounts sufficient to provide the foaming additive concentrations shown in Table B. Column A lists dilute concentrations, Column B lists immediate (preferred) concentrations and Column C lists higher concentrations.
