摘要：The invention relates to a method for improving the efficiency of surfactantswith the simultaneous suppression of lamellar mesophases, in particular in micro-emulsions and emulsions and to surfactants, which are mixed with an additive. Accordingto the invention, to improve the efficiency of the surfactants, a block copolymer of typeAB, ABA or BAB is added to latter, said polymer comprising a water-soluble block A andan oil-soluble block B, which is a polyalkylene oxide, whose monomer units contain atleast 4 carbon atoms. Said block copolymers also prevent lamellar mesophases, stabilisethe temperature of the one-phase ranges for oil, water or surfactant mixtures, enlargethe structural quantity and reduce the interfacial tension of said mixtures.
