Abstract
A method of fighting a fire includes aerating a firefighting foam composition to form an aerated firefighting foam; administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid; wherein: the firefighting foam composition includes a sugar component; a surfactant component comprising an anionic surfactant, a zwitterionic surfactant, or a mixture of any two or more thereof; a polysaccharide thickener comprising succinoglycan; and at least about 30 wt. % water.
Claims17
A firefighting foam concentrate comprising:
- a sugar component comprising at least about 50 wt. % of a monosaccharide, sugar alcohol, or a mixture of any two or more thereof;
- a surfactant component comprising an anionic surfactant and a zwitterionic surfactant;
- a polysaccharide thickener comprising succinoglycan;
- a suspension agent comprising microfibrous cellulose;
- and
- wherein the firefighting foam concentrate is substantially free of non-ionic surfactants.
A method of making a firefighting foam concentrate, the method comprising:
- forming a suspension agent by blending microfibrous cellulose with a solvent at sufficient shear to disperse fibers of the microfibrous cellulose in the solvent;
- blending the suspension agent with:
- a sugar component comprising at least about 50 wt. % of a monosaccharide, sugar alcohol, or a mixture of any two or more thereof;
- a surfactant component comprising an anionic surfactant and a zwitterionic surfactant;
- and
- a polysaccharide thickener comprising succinoglycan;
- and
- wherein the firefighting foam concentrate is substantially free of non-ionic surfactants.
A method of fighting a fire comprising:
- aerating a firefighting foam composition to form an aerated firefighting foam;
- administering the aerated firefighting foam to a fire or applying the aerated firefighting foam to a surface of a volatile flammable liquid;
- wherein:
- the firefighting foam composition comprises:
- a sugar component;
- a surfactant component comprising an anionic surfactant and a zwitterionic surfactant;
- a polysaccharide thickener comprising succinoglycan;
- a suspension agent comprising microfibrous cellulose;
- and
- at least about 30 wt. % water;
- and
- wherein the firefighting foam composition is substantially free of non-ionic surfactants.
