| 1 | To a secondary vessel add phase A, start mixing and slowly add phase B components individually to phase A with continued mixing. |
| 2 | Heat phase AB to 85°C and then add phase C ingredients with mixing. |
| 3 | To the main vessel add the Water of phase D, start mixing, add the Disodium EDTA, then add the Pemulen ® TR-2, and heat this phase to 80°C. |
| 4 | When both phases ABC and D are homogeneous and at designated temperatures, slowly add phase ABC to phase D with mixing. |
| 5 | Start homogenizing intensively for 3 minutes and start cooling with continued homogenization. When the batch is at 55°C add phase E. |
| 6 | Stop homogenizing and resume sweep mixing. Add phase F premix, mix well and then add phase G. |
| 7 | When the batch is uniform add deionized water to correct for evaporative losses. Continue mixing until smooth. |
