Cool burning gas generant compositions for an automotive inflatable restraint system are provided that include a bismuth-containing compound selected from the group consisting of: bismuth citrate, bismuth subsalicylate, bismuth hydroxide, copper bismuth hydroxy nitrate, bismuth subcarbonate, bismuth suboxalate, and combinations thereof. The gas generant comprises at least one copper-containing component. The gas generant includes at least one oxidizer, fuel, and optional coolant. The maximum flame temperature at combustion (Tc) of less than or equal to about 1700K (1,427° C.). The cool burning gas generant composition generates liquid phase combustion products making it suitable for use in a filterless inflatable restraint system. Copper and bismuth present in the cool burning gas generant composition react to form an alloy having a melting point at or near the maximum flame temperature at combustion (Tc).
