The object of the present invention is a method for producing oil-in-water (O/W) emulsions from self-emulsifying O/W gel concentrates without agitation, such as stirring, or in a laminar flow field.

Method for producing oil-in-water emulsions from self-emulsifying gel concentrates

The invention relates to a method for increasing the efficiency of surfactants as well as to a method for suppressing lamellar mesophases in microemulsions. According to the invention, block copolymers having a water-soluble block A and a water-insoluble part B are admixed to the surfactants. The use of these substances as additives can considerably increase the efficiency of the surfactants. Moreover, the addition of the block copolymers suppresses the formation of undesired lamellar mesophases in microemulsions.

Method for increasing the efficiency of surfactants with simultaneous suppression of lamellar mesophases and surfactants with an additive added thereto

The invention relates to a method for increasing the efficiency of surfactants and to a method for suppressing lamellar mesophases in microemulsions. Additive block co-polymers with a water-soluble block A and a water-insoluble part B are added to the surfactants. The efficiency of surfactants can be in-creased to a substantial extent by using said compounds as additives. The formation of undesirable lamellar mesophases in microemulsions is suppressed by adding said block co-polymers.
