Abstract
The novel surfactant compositions are obtained by mixing 1 part by weight of at least one nonionic surfactant and 0.3 to 9 parts by weight of a specific mixture composed of water and at least one anionic surfactant and at least one cationic surfactant. The said surfactant compositions are concentrated and generally clear liquids which, in particular, have good foaming and wetting characteristics, low surface tension and a low pour point and are versatile by virtue of these particular properties.
