Procedure: Charge A water into a suitable vessel. Disperse B into C in a separate vessel. Disperse D into BC and mix until uniform. Add BCD with propeller mixing. Mix until uniform. Add E to ABCD and mix until uniform. Add F to batch with homogenization. Homogenize until uniform. Begin heating to 72°C. Combine G and heat to 75°C. When both phases are at the proper temperature, add G to batch under propeller mixing. Mix until uniform. Maintain 72°C for 15 min. Cool to 40°C. Add the premix H to the batch and mix until uniform. Cool to 25°C. Store in airtight containers.
