Abstract: Provided is a gas generating composition which can maintain stable combustion performance even under variation of ambient temperature. The gas generating composition includes (a) a fuel and (b) an oxidizing agent and meets the following requirements (I) and (II): (I) a combustion temperature at a time of ignition and combustion at any ambient temperature within a range of ?40° C. to 85° C. is a melting point of a substance included in a combustion residue; and (II) a difference between combustion temperatures at the time of ignition and combustion at ambient temperatures of ?40° C. and 85° C. is less than 125 K.

Abstract: Provided is a gas generating composition that maintains stable ignition performance for a long period. A gas generating composition includes: a gas generating agent including (a) fuel selected from a triazine compound and a guanidine compound, (b) an oxidizing agent including a Combination of (b-1) basic metal nitrate and (b-2) basic metal carbonate, and (c) a binder; and (d) an absorbent. The gas generating agent and the absorbent may not be integrally molded or may be integrally molded.

Abstract: A gas generating composition exhibiting good slag forming ability is provided. The gas generating composition includes a fuel ranging from 10 to 60% by mass, an oxidizing agent ranging from 10 to 70% by mass, and a cooling agent (other than iron oxide) ranging from 1 to 20% by mass. The cooling agent has a volume mean diameter (D50) of 10 to 70 ?m and a volume mean diameter at cumulative of 10% (D10) of equal to or greater than 5 ?m. The cooling agent acts to decrease the combustion temperature and improve slag forming ability.
