The disclosed invention relates to novel biocompatible firefighting foam compositions that include a deep eutectic solvent. Disclosed are methods of making and using firefighting foams containing deep eutectic solvents, which may also be used in existing fire foam compositions as drop in solvent additives. The deep eutectic solvents may also be used in or as a principle component of surrogate firefighting foam compositions.

Firefighting foam compositions containing deep eutectic solvents

Aqueous film forming firefighting composition concentrates are provided that contain an effective amount of a monomeric zwitterionic or anionic Cperfluoroalkyl surfactant having a molecule weight less than 800 daltons. The compositions also contain an effective amount of a foam stabilizing agent, and an effective amount of at least one non-fluorinated surfactant. The composition has less than 0.8% F, and is substantially free of any surfactant containing a perfluoroalkyl group containing more than 6 carbon atoms. The composition meets Military Specification MIL-F-24385F.

Aqueous fire-fighting foams with reduced fluorine content
