| 1 | In a secondary vessel, add phase A ingredients and start mixing. Then add phase B ingredients to phase A, one at a time. |
| 2 | When phase AB is uniform, add phase C and begin heating phase ABC to 90°C. Then add phase D to phase ABC, in order. |
| 3 | To the main vessel, add water from phase E and begin mixing. Dissolve the Tetrasodium EDTA, then add Tromethamine and heat to 90°C. |
| 4 | Premix phase F in a separate vessel and then add to phase E just before combining oil phase ABCD to water phase EF. |
| 5 | When both phases ABCD and EF are homogenous and at temperature, add oil phase ABCD to water phase EF with strong mixing. |
| 6 | After 10 minutes, homogenize and cool until batch is at 55°C or for 3 minutes, then return to prop mixing and continue cooling. |
| 7 | When batch is below 45°C, add phase G ingredients with mixing in between and until uniform. Replace water lost. Perform QA checks. |
