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. |
| 6 | Add premixed phase F (Triethanolamine level adjusted as need be for pH 7.5-8.0) to phase ABCDE. |
| 7 | Start cooling batch and when batch is < 50°C add phase G one by one with mixing |
| 8 | Continue mixing until batch is at room temperature, replacing any water lost to evaporation and mixing until smooth. |
