A foam concentrate provides a fire-fighting composition when mixed with water so that the fire-fighting composition does not form a stable seal on cyclohexane and meets UL 162, Class B performance criteria for at least one of AFFF agents and fluoroprotein (FP) agents without requiring organic fluorine. The concentrate is formed from water and a high molecular weight acidic polymer (HMWAP) and a coordinating salt.
