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.
A method of firefighting including the steps of preparing a biodegradable, non-toxic foamable firefighting concentrate composition comprising, by volume, from about 4 to about 40 parts of an ethoxylated tertiary amine having 2-10 ethoxy groups per mol selected from the group consisting of C16-C18 animal-based tallow amines and coconut amines, from about 1 to about 15 parts of at least one aliphatic carboxylic acid having from 6 to 12 carbon atoms;
A biodegradable, non-toxic firefighting concentrate composition capable of dispersing hydrocarbon fuels in water and thus extinguishing hydrocarbon fuel fires, said composition comprising, by volume, from about 4 to about 40 parts of an alkoxylated tertiary amine having 2-10 alkoxy groups per mol selected from the group consisting of one or more C16-C18 animal-based tallow amines and coconut amines, from about 1 to about 15 parts of at least one aliphatic carboxylic acid having from 6 to 12 carbon atoms;
A biodegradable, non-toxic firefighting concentrate composition, said composition comprising, by volume, from about 4 to about 40 parts of an alkoxylated tertiary amine surfactant selected from the group consisting of C16-C18 animal-based tallow amines and coconut amines, from about 1 to about 15 parts of at least one carboxylic acid having from 4 to 16 carbon atoms;
A surfactant composition for dilution with water to create a firefighting concentrate, said surfactant composition comprising about 56% of an alkoxylated C16-C10 tertiary amine surfactant, about 34% of a carboxylic acid having from about 4 to 16 carbon atoms and about 10% of at least one C6-C16 alcohol, said tertiary amine surfactant including a lipophilic portion and a hydrophilic portion rendering said amine surfactant, in the presence of said acid and said alcohol, capable of emulsifying petroleum hydrocarbons in water, said surfactant composition being dilutable with water to form a concentrate wherein said surfactant composition is present in an amount of about 15% to about 60% of said firefighting concentrate.
