A liquid electrically initiated and controlled composition comprising an oxidizer, soluble fuel additive(s), and other optional additives to enhance the chemical or ballistic properties, or a combination thereof is disclosed. The liquid composition further comprises stabilizers to enhance thermal stability, sequestrants to minimize deleterious effects of transition metal contaminants, and combustion enhancers maximizing efficiency. Buffers and heavy metal sequestering or complexing agents may be used in combination to achieve the highest degree of thermal stability. Additional ionic co-oxidizers may be added to the liquid composition to stabilize the liquid oxidizer and further depress freezing point. The liquid phase of matter allows flow via pipes or tubes from tanks, reservoirs, or other containers, through metering valves, followed by ignition or combustion modulation when stimulated by electrodes, statically or dynamically.
