PREPARATIVE PROCEDURE
| 1 | To a secondary vessel add phase A and start mixing, add phase B and heat to 80°C. |
| 2 | Add phase C into phase AB, mixing well until all are dissolved, and then homogenize for 3 minutes. |
| 3 | To the main vessel add the Water of phase D, start mixing and add remaining phase items in order. |
| 4 | When solids of phase D are fully incorporated, heat phase to 75°C. |
| 5 | When both phases are homogeneous and at their designated temperatures, slowly add phase ABC to phase D with prop mixing. |
| 6 | After 5 minutes start cooling batch and when batch is below 50°C add premixed phase E and then phase F. |
| 7 | Continue mixing until batch is at room temperature, replacing any water lost to evaporation and mixing until smooth. |
