Abstract

The invention relates to a composition which is designed to be used as a cleaning agent and oil dispersant. The composition has a number of active ingredients mixed with water. The solution provides for the use of such active ingredients as sodium lauryl sulfate, cocamidopropyl betaine, ethoxylated nonylphenol, lauric acid diethanolamide, diethanolamine and propylene glycol. Preferred compositions contain the following ingredients mixed in an aqueous base: from 0.02% to 2.25% by total weight of sodium lauryl sulfate, from 0.02% to 1.95% by total weight of cocamidopropyl betaine, from 0.002% to 0.25% by total weight of ethoxylated nonylphenol, from 0.04% to 4.25% of lauric acid diethanolamide, from 0.02% to 1.85% by total weight of diethanolamine and from 0.02% to 1.85% by total weight of propylene glycol.

Claims

1. An aqueous composition suitable for use as a cleaning agent or as an oil dispersant, comprising:

sodium lauryl sulfate, from 0.02% to 2.25% by total weight;

cocamidopropyl betaine, from 0.02% to 1.95% by total weight;

ethoxylated nonylphenol, from 0.002% to 0.25% by total weight;

lauric acid diethanolamide, from 0.04% to 4.25% by total weight;

diethanolamine, from 0.02% to 1.85% by total weight; and

propylene glycol, from 0.02% to 1.85% by total weight.

4. The cleaning agent of claim 1 wherein the active ingredients comprise 1.5% of sodium lauryl sulfate by total weight, 1.3% of cocamidopropyl betaine by total weight, 0.17% of ethoxylated nonylphenol by total weight, 2.83% of lauric acid diethanolamide by total weight, 1.23% of diethanolamine by total weight, 1.23% of propylene glycol by total weight and mixed in an aqueous base.

2. The oil dispersant of claim 2, wherein the solution contains at least 1.23% by total weight of diethanolamine.

3. The oil dispersant solution of claim 2, wherein the solution contains at least 1.2% by total weight of propylene glycol.

5. A process of manufacturing an oil dispersant, comprising the steps of:

dissolving 1.5% by total weight of sodium lauryl sulfate in 25.07% percent by total weight of water;

adding in sequence, while continuously agitating the solution, at least 1.3% by total weight of cocamidopropyl betaine, at least 0.17% by total weight of ethoxylated nonylphenol, at least 2.3% by total weight of lauric acid diethanolamide, at least 1.23% by total weight of diethanolamide, at least 1.23% by total weight of propylene glycol;

adding with continuous agitation 66.67% by total weight of water, thus forming an aqueous solution having at least 8.26% by total weight of active ingredients.

6. A method of dispersing oil without destroying microbial genera, which comprises the step of dispersing on oil surface an aqueous solution, comprising:

from 0.02% to 2.25% by total weight of sodium lauryl sulfate;

from 0.02% to 1.95% by total weight of cocamidopropyl betaine;

from 0.002% to 0.25% by total weight of ethoxylated nonylphenol;

from 0.04% to 4.25% by total weight of lauric acid diethanolamide;

from 0.02% to 1.85% by total weight of diethanolamine; and

from 0.02% to 1.85% by total weight of propylene glycol.

7. The method of claim 6, wherein concentration of the active ingredients is at least 8.26% by total weight.

8. The method of claim 6, wherein the active ingredients comprise:

1.5% by total weight of sodium lauryl sulfate, 1.3% by total weight of cocamidopropyl betaine, 0.17% by total weight of ethoxylated nonylphenol, 2.83% by total weight of lauric acid diethanolamide, 1.23% by total weight of diethanolamine and 1.23% by total weight of propylene glycol mixed in an aqueous base.
