Abstract
An aqueous fluorine-free, fire-fighting composition including a sugar component, an anionic surfactant, a zwitterionic surfactant, water-miscible organic solvent, and a nonionic surfactant, is provided.
Claims19
An aqueous fluorine-free, fire-fighting foam composition comprising:
- a sugar component comprising a monosaccharide sugar, a disaccharide sugar, a sugar alcohol, or a mixture of any two or more thereof;
- a nonionic surfactant comprising an alkyl polyglycoside, an aliphatic alcohol, or a mixture of any two or more thereof;
- optionally, a second surfactant component comprising an anionic surfactant, a zwitterionic surfactant, or a mixture of any two or more thereof;
- and
- a water-miscible organic solvent;
- wherein the composition is substantially free of a polysaccharide thickener.

An aqueous fluorine-free, fire-fighting foam composition comprising:
- about 5 to 25 wt. % of a sugar component comprising a monosaccharide sugar, a disaccharide sugar, a sugar alcohol, or a mixture of two or more thereof;
- about 5 to 25 wt. % of an anionic surfactant;
- about 2 to 15 wt. % of the zwitterionic surfactant;
- about 1 to 30 wt. % of a water-miscible organic solvent;
- and
- about 2 to 15 wt. % of a nonionic surfactant comprising an alkyl polyglycoside, an aliphatic alcohol, or a mixture of any two or more thereof;
- wherein the composition is substantially free of a polysaccharide thickener.
