Wetting agent composition for extinguishing fires

An infiltrative extinguishing agent composition comprising:

• 5-10.9% by weight of a metal carbonate or metal bicarbonate;
• 1-8% by weight of urea;
• 3-10% by weight of a freezing point lowering agent;
• 0.03-5% by weight of a fluorine-based surfactant;
• 0.5-10% by weight of an amphoteric surfactant;
• and
• 76.7-90% by weight of water,
• wherein the composition has a hydrogen ion concentration (pH) of 6 to 9 at a temperature of 19.5° C. to 20.5° C.,
• wherein the composition does not undergo solution separation at a temperature of 0° C. to 50° C., and
• wherein the amphoteric surfactant is one or more selected from the group consisting of lauramido propyl betaine, cocamido propyl betaine, meadowfoam amido propyl betaine, coco dimethyl carboxymethyl betaine, cetyl dimethyl carboxymethyl betaine, oleyl dimethyl gamma-carboxypropyl betaine, coco amido disodium 3-hydroxypropyl phosphobetaine,lauric myristic amido disodium 3-hydroxypropyl phosphobetaine, lauric myristic amido glyceryl phosphobetaine, lauric myristic amido carboxy disodium 3-hydroxypropyl phosphobetaine, sodium cocoyl sarcosinate, sodium cocoamphoacetate, disodium cocoamphodiacetate, ammonium cocoyl sarcosinate, sodium cocoamphopropionate, coco amido dimethyl propyl suitaine, stearyl-amido dimethyl propyl sultaine, laurylamido-bis-(2-hydroxyethyl) propylsultaine, coco amido propyl monosodium phosphitaine and lauric myristic amido propyl monosodium phosphitaine.
