Abstract of the Disclosure Automotive airbag gas generant formulation providing an alternative to commercially used formulations containing sodium azide. The composition comprises from about 25% to about 75% by weight of a heterocyclic compound having the following structure: Image wherein R is selected from hydrogen, -CO2X, and -OX and X is a cation providing an anhydrous salt. The other principal ingredient of the composition is from about 25% to 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of Group I-A of the Periodic Table (except sodium) calcium strontium or barium and an anion which is essentially free of carbon hydrogen or halogens. From about 0% to 2% of a binder can be added if necessary. An automotive airbag inflator containing the composition and a method for generating gas comprising the step of igniting the composition stated above are also disclosed.
