Abstract (en)
[origin: WO2006060993A1] The invention relates to a method for improving the efficiency of surfactants with the simultaneous suppression of lamellar mesophases, in particular in micro-emulsions and emulsions and to surfactants, which are mixed with an additive. According to the invention, to improve the efficiency of the surfactants, a block copolymer of type AB, ABA or BAB is added to latter, said polymer comprising a water-soluble block A and an oil-soluble block B, which is a polyalkylene oxide, whose monomer units contain at least 4 carbon atoms. Said block copolymers also prevent lamellar mesophases, stabilise the temperature of the one-phase ranges for oil, water or surfactant mixtures, enlarge the structural quantity and reduce the interfacial tension of said mixtures.
