Abstract

The present disclosure pertains to surfactants for use in the formulation of detergents, foaming agents, emulsifiers, and degreasers. Some aspects of the invention include formulations suitable for cleaning and/or condition fabrics including upholstery. Some formulations are suitable for in home or commercial dry cleaning. Some of the formulations may be suitable for cleaning hard surfaces including plastic surfaces.

First claim

The invention claimed is:

1. A formulation for cleaning, comprising:
at least one surfactant of Formula I,

wherein R 1 and R 2 may be the same or different, and comprise at least one group selected from the group consisting of C 1 -C 6 alkyl, optionally the C 1 -C 6 alkyl may comprise one or more of oxygen, nitrogen, or sulfur atoms or groups that comprise at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 3 to 12;
the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl;
an optional counterion associated with the compound which, if present, is selected from the group consisting of chloride, bromide, and iodide; and
at least one detergent or at least one soap.

2. The formulation according to claim 1 , wherein the at least one detergent or soap is selected from the group consisting of: anionic detergents, cationic detergents, non-ionic detergents, and zwitterionic detergents.

3. The formulation according to claim 1 , wherein the soap is of the general formula:
(RCO 2 − ) n M n+
wherein R comprises an alkyl group, M is a metal, and n+ is either 1 or +2.

4. The formulations of claim 1 , further comprising: at least one builder.

5. The formulation according to claim 4 , wherein the at least one builder is at least one compound selected from the group consisting of: tripolyphosphates, nitriloacetic acid salts, zeolites, calcite/carbonate, citrate or polymers, sodium, pyrophosphate, orthophosphate, sodium aluminosilicate, inorganic salts of alkaline agents, inorganic salts of alkali metals, sulphates, silicates, and metasilicates.

6. The formulations according to claim 1 , further comprising: at least one bleach.

7. The formulation according to claim 6 , wherein the at least one bleach at is at least one compound selected from the group consisting of: metal borates, persalts, peroxyacids, percarbonates, perphophates, persilicates, persulfates, sodium hypochlorite, chlorine dioxide, hydrogen peroxide, sodium percarbonate, sodium perborate, peroxoacetic acid, benzol peroxide, potassium persulfate, potassium permanganate, and sodium dithionite.

8. The formulations according to claim 1 , further comprising: at least one enzyme.

9. The formulations according to claim 8 , where the at least one enzyme is selected from the group consisting of: proteases, amylases, cellulases, oxidases, mannanases, peroxidases and lipases.

10. The formulations according to claim 1 , further comprising at least one polymer.

11. The formulations according to claim 10 , wherein the at least one polymer is at least one compound selected from the group consisting of: polymers of methacrylamide, polymers of ethylenically unsaturated monomer, N, N-dialkylaminoalkyl methacrylate, N, N-di alkylaminoalkyl acrylate, N, N-dialkylaminoalkyl acrylamide, N, N-dialkylaminoalkylmethacrylamide, methacylamidoalkyl trialkylammonium salts, acrylamidoalkylltrialkylamminium salts, vinylamine, vinyl imidazole, quaternized vinyl imidazole and diallyl dialkyl ammonium salts, polymers of: diallyl dimethyl ammonium salt, N,N-dimethyl aminoethyl acrylate, N,N-dimethyl amino ethyl methacrylate, [2-(methacryloylamino) ethyl] trimethylammonium salt, N,N-dimethylaminopropyl acrylamide, N,N-dimethylaminopropyl methacrylamide, acrylamidopropyl trimethyl ammonium salts, methacrylamidopropyl trimethylammonium salts, and quaternized vinylimidazole.

12. A formulation for dry cleaning, comprising:
at least one surfactant of Formula I,

wherein R 1 and R 2 may be the same or different, and comprise at least one group selected from the group consisting of C 1 -C 6 alkyl, optionally the C 1 -C 6 alkyl may comprises one or more of oxygen, nitrogen, or sulfur atoms or groups that comprises at least one of these atoms, and the alkyl chain may be optionally substituted with one or more substituents selected from the group consisting of hydroxyl, amino, amido, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylate;
n is an integer from 3 to 12;
the terminal nitrogen is optionally further substituted with R 3 , wherein R 3 is selected from the group consisting of hydrogen, oxygen, hydroxyl, and C 1 -C 6 alkyl;
