AQUEOUS FOAMING COMPOSITION FOR DEGASATION OF TOXIC CHEMICALS Russian patent published in 2015 - IPC A62D3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to safe operation of chemically hazardous facilities, i.e. development of a formulation for the decontamination of toxic chemicals (TC) during emergency response operations at chemically hazardous facilities. Development of a foaming aqueous composition comprising the following components: foaming composition - 0.3-1.7 wt %, Na-salt of dichloroisocyanuric acid - 2.5-6.5 wt %, water - the rest. The foaming composition comprises a mixture of primary fatty alcohols and functional additives, as well as butyldiglycol, propylene glycol and water at the ratio: mixture of 3-ethanolaminoalkylsulphate of C₈-C₁₂ primary fatty alcohols, C₁₂-C₁₄ primary fatty alcohols, sodium sulphoethoxylate and carbamide - 40.0 wt %, butyldiglycol - 5.0 wt %, propylene glycol - 3.0 wt %, water - the rest.

EFFECT: invention provides the degasation of TC during emergency response operations at chemically hazardous facilities.
