Abstract: A foam stabilizing composition includes a) colloidal silica and b) a siloxane cationic surfactant. The siloxane cationic surfactant includes a cationic moiety having the formula Z1-D1-N(Y)a(R)2-a, where Z1 is a siloxane moiety, D1 is 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-NR13+, where D is a divalent linking group and each R1 is independently an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms. A firefighting includes the foam stabilizing composition and water. Methods of making and using the same are also provided.

Abstract: A foam stabilizing composition includes a silane surfactant, a nonionic surfactant, a zwitterionic surfactant, and water. The foam stabilizing composition is useful for preparing a firefighting foam.
