1To a secondary vessel add phase A, start mixing, add phase B and heat to 80°C.
2Add phase C to phase AB, mix well until newly added items are dissolved and then homogenize for 3 minutes.
3To the main vessel add phase D, start mixing and add phase E items in order.
4When solids of phase E are fully incorporated, heat phase DE to 75°C.
5When both phases are homogeneous and at their designated temperatures, slowly add phase ABC to phase DE with prop mixing.
6After 5 minutes start cooling batch and when batch is below 50°C add phase F items one by one with mixing.
7Add Phase G if the batch is too thin.
8Continue mixing until batch is at room temperature, replacing any water lost to evaporation and mixing until smooth.
