Biodegradable suspension forming compositions
A fire suppression composition includes starch, a pseudo-plastic, high yield, suspending agent, and agglomerating material.
1. A fire suppression composition comprising a concentrate free of liquid water, the concentrate adapted to dilution with water to form a fire suppression suspension, the concentrate comprising a dispersion comprising:
about 0.1 to 10 wt. % of a hydrophobic liquid material comprising an olefin having 20 carbon atoms or less;
about 35 to 65 wt. % of a starch; and
about 25 to 55 wt. % of a pseudoplastic, high yield, sodium polyacrylate suspending agent;
wherein the composition and its byproducts are neither corrosive nor toxic.
2. The composition of claim 1 wherein the composition comprises a blended starch.
3. The composition of claim 1 wherein the hydrophobic liquid material comprises an olefin having 10 to 18 carbon atoms.
4. The composition of claim 1 comprising a powdered or agglomerated material.
5. An aqueous composition comprising a dispersion comprising 0.1 to 5 wt. % of the fire suspension composition of claim 1 in water.
6. The composition of claim 1 additionally comprising a clay.
