Add E to the main vessel, dissolve F with continued mixing, then add G, stirring until fully incorporated. Start heating to 80°C and add premix of H. When both phases are homogeneous and at their designated temperatures, slowly add the oil phase (Au2013D) to the water phase (Eu2013H) with prop mixing. Start homogenizing and cooling. When batch reaches 55°C, start sweep mixing and continue cooling. Add I and continue mixing until fully incorporated. Add J and continue mixing until fully incorporated.
