A foamable surfactant composition characterized by increased foam height comprising as the surfactant: a) a zwitterionic surfactant or b) a nonionic alkylphenol ethyoxylate surfactant or c) a blend of two or more nonionic, anionic, cationic and zwitterionic surfactants in a total amount sufficient to produce a foam in water; and d) a polygalactomannan in an amount sufficient to elevate the foam height of an aqueous solution of said surfactant at least 5 millimeters above a control of the surfactant without the polygalactomannan. These compositions provide increased foam height at the same level of surfactant or the same foam height at a reduced level of surfactant.
