Abstract
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.
