Abstract
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.
