A gas generant composition for passive inflatable restraint systems (e.g., airbags) for automobiles is provided that comprises a melamine oxalate compound. The gas generant may be a cool burning gas generant composition that comprises a melamine oxalate compound, a co-fuel, such as guanidine nitrate, and an oxidizer, such as basic copper nitrate. The gas generant composition has advantageous combustion properties, including a maximum flame temperature at combustion (T
c
) of ≤about 1700 K (1,427° C.), a linear burn rate of ≥about 18 mm per second at a pressure of about 10 megapascals (MPa), a gas yield of the gas generant composition of ≥about 5.7 moles/100 cm
3
, and a linear burn rate pressure exponent of ≤about 0.35.
