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 method of forming a colloidal concentrate for cleaning, the method comprising:

combining, in a mixing bottle, up to one gallon of water with a formulation comprising, on a wt % basis;

(i) 15% to 50% of a boron-containing anionic builder;

(ii) 20%-70% of a carbonate or percarbonate builder;

(iii) 5% to 20% of soap; and

mixing, by manually shaking or stirring, the combined water and formulation in the mixing bottle to form the colloidal concentrate.

3. The method of claim 1 wherein the soap includes at least 1 part in 10 by molar ratio of glycerin relative to the fatty acid content of the soap.

2. A method of forming a colloidal concentrate for cleaning, the method comprising:

combining, in a mixing bottle, up to one gallon of water with a formulation comprising, on a wt % basis;

(i) 15% to 50% of a boron-containing anionic builder;

(ii) 20%-70% of a carbonate or percarbonate builder;

(iii) 5% to 20% of soap;

(iv) 1% to 20% of an emulsifier; and

mixing, by manually shaking or stirring, the combined water and formulation in the mixing bottle to form the colloidal concentrate.
