Abstract
A method of making a fire extinguishing composition comprises: forming a first aqueous solution of potassium acetate, potassium formate, or a combination thereof; forming a second aqueous solution comprising a biocide, a bio-surfactant and an optional corrosion inhibitor; combining the first aqueous solution with the second aqueous solution to form a third aqueous solution and mixing until the third aqueous solution is transparent; adding a chelating agent to the transparent third aqueous solution and mixing to form a transparent fourth aqueous solution. A fire extinguishing composition made by the method is also disclosed.

A method of making a fire extinguishing composition comprising:
- forming a first aqueous solution of potassium acetate, potassium formate, or a combination thereof;
- forming a second aqueous solution comprising a biocide, a bio-surfactant and an optional corrosion inhibitor;
- combining the first aqueous solution with the second aqueous solution to form a third aqueous solution and mixing until the third aqueous solution is transparent;
- adding a chelating agent to the transparent third aqueous solution and mixing to form a transparent fourth aqueous solution,
- wherein the bio-surfactant comprises a non-ionic alkyl glycoside in an amount of 1 to 10 weight percent (wt %), based on the weight of the fourth aqueous solution.
