Procedure
Charge water into main vessel. Add Natrlquest E30. With high mixing, sprinkle in the Activsoft CD. Mix until dispersed. Add a trace amount of citric acid solution. Batch will clear. Begin heating batch to 50°C. Add Phase B sequentially. Heat and mix until uniform. Cut the heat off. Add phase C. At 40-45°C, add phase D one at a time. In a side vessel, pre-mix Phase E. Slowly add the pre-mix to the batch in aliquots. Do not add all at once. Adjust the pH using the sodium hydroxide solution to 6.0-7.0. Viscosity can be tweaked further with the addition of sodium chloride.
