Disclosed is a method for improving efficacy of surfactants, prevention of lamellar mesophases, temperature stabilization of the single phase region and a method for reducing boundary surface tension in micro-emulsions containing silicone oils by means of additives and a surfactant/oil mixture. The above effects are achieved, whereby an additive of a block copolymer with a water-soluble block A and a block B which is either a polyalkylene oxide with at least 4 C atoms in the monomer component or a polydiene or a partially or completely hydrogenated polydiene or polyalkane, is added to the micro-emulsion.
A method for increasing the efficiency of surfactants in microemulsions that contain at least one silicone oil, comprising adding to one of said microemulsions as an additive a block copolymer having a water-soluble block A and a block B that is either a polyalkylene oxide having at least 4 carbon atoms in a monomer component or a polydiene or a partially or completely hydrogenated polydiene or a polyalkane.
A method for suppressing lamellar phases in a water/oil/surfactant mixtures that contain at least one silicone, comprising adding to one of said mixtures as an additive a block copolymer having a water-soluble block A and a block B that is either a polyalkylene oxide having at least 4 carbon atoms in a monomer component or a polydiene or a partially or completely hydrogenated polydiene or a polyalkane.
A method for stabilizing a temperature position of a monophase area for oil/water/surfactant mixtures that contain at least one silicone oil, comprising adding to one of said oil/water/surfactant mixtures as an additive a block copolymer having a water-soluble block A and a block B that is either a polyalkylene oxide having at least 4 carbon atoms in a monomer component or a polydiene or a partially or completely hydrogenated polydiene or a polyalkane.
A method for reducing an interfacial surface tension of oil/water mixtures that contain surfactants and at least one silicone oil, comprising adding to one of said oil/water mixtures as an additive a block copolymer having a water-soluble block A and a block B that is either a polyalkylene oxide having at least 4 carbon atoms in a monomer component or a polydiene or a partially or completely hydrogenated polydiene or a polyalkane.
