The phase assembly temperature can be determined visually by the achievement of translucence in the composition or by measures such as conductivity which peaks and then is maintained at a plateau whilst phase assembly occurs. It has been found that whilst if a non-surfactant amphiphilic type compound such as the polyol is added together with the second part as would conventionally be the case, a microemulsion or sub-micron emulsion is not formed, by adding the so called third part, phase assembly occurs at a lower temperature than would be expected and moreover, this phase appears to assist in maintaining the microemulsion or sub-micron emulsion characteristics of the formulation during storage at normal temperatures.
