Abstract
Official abstract text for this publication.
An aqueous fire-fighting composition includes a surfactant component that includes an anionic surfactant, a zwitterionic surfactant, a nonionic surfactant, or a mixture of any two or more thereof, and a suspension agent comprising microfibrous cellulose. The suspension agent may include a water-soluble oligosaccharide and/or polysaccharide co-agent together with the microfibrous cellulose. The fire-fighting composition may also include one or more of a sugar component, organic solvent and a polysaccharide thickener, and be substantially free of fluorinated additives.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous fire-fighting composition comprising: a sugar component; a polysaccharide thickener; a surfactant component comprising an anionic surfactant, a zwitterionic surfactant, or a mixture thereof: a suspension agent comprising a microfibrillated cellulose; and at least about 30 wt. % water; wherein: the polysaccharide thickener is at least partially insoluble in the aqueous fire-fighting composition and the fire-fighting composition is substantially free of non-ionic surfactants. 2. The aqueous fire-fighting composition of claim 1 , wherein the sugar component comprises glucose, fructose, mannose, xylose, xylitol, sorbitol, mannitol, or a mixture of any two or more thereof. 3. The aqueous fire-fighting composition of claim 1 , wherein the surfactant component comprises a betaine and/or sultaine zwitterionic surfactant; and an alkyl sulfate and/or alkyl ether sulfate.
