ABSTRACT:
Biodegradable foam compositions for extinguishing class B fires are disclosed that may be in either a liquid concentrate or a powder concentrate form. The concentrates comprise (1) a foaming group including a high-foaming surfactant such as an alkyl polyglycoside and a plurality of viscosity-reducing agents, for example, polyethylene glycol, and (2) a stiffening group including a water-soluble polymer such as a natural gum, e.g., xanthan gum, and a viscosity-reducing agent. The powder concentrate further comprises a sorption agent.
