A foam stabilizing composition is disclosed. The composition comprises (A) a siloxane cationic surfactant comprising a cationic moiety having the formula Z-D-N(Y)(R), wherein Zis a siloxane moiety, Dis a divalent linking group, R is H or an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms, subscript a is 1 or 2, and each Y has formula -D-NR+, where D is a divalent linking group and each Ris independently an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms. The composition also comprises (B) an organic cationic surfactant comprising a cationic moiety having the formula Z-D-N(Y)(R), wherein Zis an unsubstituted hydrocarbyl group, Dis a covalent bond or a divalent linking group, subscript b is 1 or 2, and R, Y, and subscript a, are defined above. An aqueous film-forming foam comprising the composition and method of using the same are also disclosed.
