An airbag explosive composition containing a fuel ingredient, an oxidizing agent, and a binder for them, wherein the binder is a hydrotalcite represented by the following general formula (1): [M<2+>1-xM<3+>x(OH)2]<x+>[Ax/n.mH2O], wherein M<2+> represents a divalent metal such as Mg<2+>, Mn<2+>, Fe<2+>, Co<2+>, Ni<2+>, Cu<2+> or Zn<2+>; M<3+> represents a trivalent metal such as Al<3+>, Fe<3+>, Cr<3+>, Co<3+> or In<3+>; A represents an n-valent anion such as OH<->, F<->, Cl<->, NO3<->, CO3<2->, SO4<2->, Fe(CN)6<3->, CH3COO<->, oxalate or salicylate; and 0 < x </= 0.33. Cette invention concerne une composition explosive pour coussin gonflable de sécurité, laquelle comprend un ingrédient combustible, un agent oxydant, et un agent de liaison de ces deux éléments, lequel agent est un hydrotalcite correspondant à la formule générale (1): [M<M+>1-xM<3+>x(OH)2]<x+>[Ax/n.mH2O] dans laquelle M<2+> représente un métal divalent tel que Mg<2+>, Mn<2+>, Fe<2+>, Co<2+>, Ni<2+>, Cu<2+> ou Zn<2+>; M<3+> représente un métal trivalent tel que Al<3+>, Fe<3+>, Cr<3+>, Co<3+> ou In<3+>; A représente un anion à n valences tel que OH<->, F<->, Cl<->, NO3<->, CO3<2->, SO4<2->, Fe(CN)6<3->, CH3COO<->, un oxalate ou un salicylate; et dans laquelle 0 < x </= 0,33.
