If the same emulsion is prepared both through cold process and the more traditional method involving heating of the phases, different internal structures can be formed. Confirmation of the theory of lamellar liquid crystal formations, can be obtained through the study of the viscosity curve and by the microscope observation of the emulsion prepared in with the two different methods.

Of the emulsions obtained during part 1 of this study, those based on the GH-6 system, containing Glyceryl Stearate, proved to be the best both for stability and for their final organoleptic characteristics. Therefore, for the next experiment we choose the following formulation:

   Hydrogenated Poly-1 Decene 5.0
   Cetyl Palmitate 4.0
   Glyceryl Stearate 2.0
   Octyl Palmitate 1.0
   Aqua 79.5
   SESAMULS® OW 4.5
   Diglycerin 4.0

The same emulsion is made through both cold process and the traditional heating method, with the classic procedure that involves the addition of the melted lipophilic phase at 70°C to the hydrophilic phase heated to the same temperature.
