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:

6-(dodecyloxy)-N,N-dimethyl-6-oxohexan-1-aminium chloride having the following formula:

and combinations thereof; and
at least one detergent or at least one soap.

2. The formulation according to claim 1 , wherein the at least one detergent 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 at least one soap is of the general formula:
(RCO 2 ′) n M n+

4. The formulation according to 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, polymer builders, sodium pyrophosphate, orthophosphate, sodium aluminosilicate, inorganic salts of alkaline agents, inorganic salts of alkali metals, sulfates, silicates, and metasilicates.

6. The formulation 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, perphosphates, persilicates, persulfates, sodium hypochlorite, chlorine dioxide, hydrogen peroxide, sodium percarbonate, sodium perborate, peroxoacetic acid, benzoyl peroxide, potassium persulfate, potassium permanganate, sodium dithionite.

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

9. The formulation 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 formulation according to claim 1 further comprising at least one polymer.
