In the primary vessel dissolve 2 in 1 and then stop mixing and sprinkle on 3. When 3 has fully wetted, resume mixing. In a separate vessel combine 4, 5 and 6 and then add to main vessel and heat this water phase to 80°C. To the secondary vessel add 7,8,9 and 10 and start mixing and heating this oil phase to 85°C. Add 11, 12 and 13 when the oil phase is at 50°C. When the oil phase is at 85°C, add 14, 15, 16 and 17. When both phases are homogeneous and at their designated temperatures, add the oil phase to the water phase with continued mixing without aeration. Maintain heat, mixing for five minutes and then homogenize for one minute (until a fine white emulsion is formed). Stop homogenizing, resume mixing and start cooling. When the batch is below 45°C, add 18. Mix until the batch is creamy smooth and below 35°C and then replace any water lost to evaporation. When again uniform, stop cooling and mixing and perform final quality assurance checks.
