Abstract

The present invention relates to both stable liquid laundry cleaning compositions and dry powdered laundry cleaning compositions with good solubility in water. More particularly, this invention relates to a concentrated soap-based formulation to be mixed with a limited quantity of water in a mixing container to render an amount of dilute liquid laundry cleaning solution with lasting stability and good cleaning properties.

Claims

1. A laundry cleaner formulation comprising 0%-20% protease, 0%-20% amylase, 5%-20% soap, 15%-50% borax decahydrate, and 20%-70% sodium carbonate monohydrate, all on a wt % basis.

2. The laundry cleaner formulation of claim 1, further comprising an emulsifier, wherein the emulsifier and soap are present in a soap:

emulsifier weight ratio from 10;

1 to 1;

1.

3. The laundry cleaner formulation of claim 2 wherein the soap is one or more of the sodium salts of carboxylic acids ranging from C6 to C18, and preferably C10 to C16.

4. The laundry cleaner formulation of claim 2, wherein the formulation consists of constituents in powder, flake, or granular forms.

5. A liquid laundry cleaner consisting of the laundry cleaner formulation of claim 2 and water, wherein the water is in an amount of from 75 wt % to 98 wt %, and preferably from 92 wt % to 98 wt %, of the liquid laundry cleaner.

6. The laundry cleaner formulation of claim 2, wherein the emulsifier has a glycerol backbone with no fewer than two side chains, with at least one side chain being a medium to long chain carboxylic acid with good hydrophobic properties, and at least one side chain having moderate hydrophillic properties, preferably of an amphoteric and/or zwitterionic nature.

7. The laundry cleaner formulation of claim 2, wherein the emulsifier is lecithin, and preferably a soya lecithin.

8. The laundry cleaner formulation of claim 2, wherein the soap and emulsifier are in powder, flake, or granular forms.

9. The laundry cleaner formulation of claim 2, wherein the soap includes at least 1 part in 10 by molar ratio of glycerin relative to the fatty acid content of the soap.

10. A laundry cleaner formulation consisting on a wt % basis of 0%-20% protease, 0%-20% amylase, 1-20% lecithin, 5%-20% soap, 15% -50% borax decahydrate, and 20%-70% sodium carbonate monohydrate.

11. The laundry cleaner formulation of claim 10, wherein the total combined protease and amylase make up no more than 30% by weight of the laundry cleaner formulation.

12. The laundry cleaner formulation of claim 10, wherein the soap is one or more of the sodium salts of carboxylic acids ranging from C6 to C18, and preferably C10 to C16.

13. The laundry cleaner formulation of claim 10, wherein each of the protease, amylase, lecithin, soap, borax decahydrate, and sodium carbonate monohydrate are in a powder, flake, or granular form.

14. A liquid laundry cleaner consisting of the laundry cleaner formulation of claim 10 and water, wherein the water is in an amount of from 75 wt % to 98 wt %, and preferably from 92 wt % to 98 wt %, of the liquid laundry cleaner.

15. A laundry cleaner formulation comprising on a wt % basis 15% to 50% of a boron-containing anionic builder, 20%-70% of a carbonate or percarbonate builder, and from 5% to 20% of soap.

16. The laundry cleaner formulation of claim 15, wherein the soap consists of one or more of the sodium salts of medium-chain carboxylic acids that are saturated, mono-unsaturated, or di-unsaturated.

17. The laundry cleaner formulation of claim 15, wherein the soap includes at least 1 part in 10 by molar ratio of glycerin relative to the fatty acid content of the soap.

18. The laundry cleaner formulation of claim 15 that further comprises an emulsifier, preferably lecithin, and most preferably soya lecithin, in an amount of from 1% to 20% by weight.

19. A liquid laundry cleaner consisting of the laundry cleaning formulation of claim 18, and water, wherein the water is in an amount of from 75 wt % to 98 wt %, and preferably from 92 wt % to 98 wt %, of the liquid laundry cleaner.

20. A method of mixing the laundry cleaner formulation of claim 18 in a mixing container or bottle with water, comprising the following steps,

a) pour the laundry cleaner formulation into the mixing container or bottle;

b) add water to the mixing container or bottle to make up to 1 gallon of solution, and

c) mix by shaking or stirring the solution in the mixing container or bottle, preferably by hand.

21. A method of mixing the laundry cleaner formulation of claim 18 in a mixing container or bottle with water, comprising the following steps,

a) pour up to 1 gallon of water into the mixing container or bottle;

b) add the laundry cleaner formulation into the water in the mixing container or bottle, and

c) mix by shaking or stirring the solution in the mixing container or bottle, preferably by hand.
