PREPARATIVE PROCEDURE

1	To a secondary vessel add phase A and start mixing. Add phase B and heat to 80°C and then add phase C.
2	To the main vessel add liquids of phase D, start mixing and add remaining phase items in order.
3	When solids of phase D are fully incorporated, heat phase to 75°C and add phase E.
4	When both phases are homogeneous and at their designated temperatures, slowly add phase ABC to phase DE with prop mixing.
5	Start homogenizing phase ABCDE for 3 minutes, then switch to center mixing.

7	Start cooling batch and when batch is < 50°C add phase G one by one with mixing
