Abstract

A biodegradable, non-toxic firefighting concentrate composition. The preferred compositions include 4 to 40 parts of a C.sub.16 -C.sub.18 tertiary amine having 2-10 ethoxy or other solubilizing groups per mol, 1 to 15 parts of a carboxylic acid having 6 to 16 carbon atoms; 1 to 6 parts of a C.sub.6 -C.sub.16 alcohol and 0 to 10 parts of C.sub.4 -and lower alcohols, and enough water to create a total of 100 parts by volume. The concentrate is usually diluted up to 100 times (v/v) with water, and is also effective when mixed with foam-forming materials. In addition, the composition is useful with soil bacteria for remediating soil contaminated with hydrocarbon fuel and for facilitating fuel dispersion and degradation within bacterial-action sewage systems.
