Phase Phase B

Phase Phase C

Phase Phase D

Phase Phase E

Phase Phase F

Phase Phase G

Phase Phase H

Phase Phase I

Procedure::
Prepare phase A by adding EDTA to water and when dissolved adding xanthan gum and mixing until fully incorporated. In a separate vessel combine phase B, start heating with mixing to 75°C, add phase C and when completed dissolved add phase D in order. In another vessel combine phase E, in order, using only enough sodium hydroxide to achieve complete solution (pH 7.5–8.0). In another vessel combine phase F and mix until a clear solution. Transfer slightly less than half of A to the empty main vessel, add phase G, and then heat to 65°C. With both  phases at indicated temperatures, add phase BCD to phase AG with mixing and then start homogenizing. After five minutes, add F to ABCDG, then add the remainder of phase A, and then add phase E. Switch from homogenization to mixing, adjust pH to 7.5-8.0 with phase H as needed, and start cooling. Add phase I with sweep mixing (to prevent aeration) and then add water as needed to correct for evaporative losses. When completely smooth, perform final quality assurance checks.
