A biodegradable, non-toxic firefighting concentrate composition. The preferred compositions include 4 to 40 parts of a tertiary amine having 2-10 ethoxy or other solubilizing groups per mol selected from the group consisting of one or more of a series of similar homologs or isomers of C16-C18 animal-based tallow amines and coconut amines, 1 to 15 parts of a carboxylic acid having 6 to 16 carbon atoms or homolog thereof; 1 to 6 parts of a C6-C16 alcohol or homolog thereof and 0 to 10 parts of C4 and lower alcohols or homologs thereof, 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.
