FOAMING COMPOSITION Russian patent published in 2016 - IPC A62D1/02 B01F17/02 

FIELD: fire safety.

SUBSTANCE: invention relates to foaming compositions which can be used in fire extinguishing, particularly when extinguishing class A and B fires, at inertisation of mines, for dust suppression in places of its occurrence. Foaming composition includes alkyl sulfate sodium salt of primary higher fatty alcohol fraction C₁₀ and sodium salts of α-olefin sulfonates of C₁₄-C₁₆ fractions, taken in weight ratio of 100:(0.025÷56.8), and water in following proportions, wt%: alkyl sulfate sodium salt of primary higher fatty alcohol fraction C₁₀ is 3.7-40.0; sodium salts of α-sulfonates of C₁₄-C₁₆ fractions is 0.015-12.6; water is rest.

EFFECT: reduction of total content of surfactant in concentrate of foaming agent, reduced kinematic viscosity at 20 °C to 11-30 mm²·s^-1.
