Continue mixing until polymer is fully hydrated. Add phase C ingredients to phase A with continued mixing. When uniform, begin heating to 60-65C. Combine phase C ingredients and heat to 60-65C. Mix until uniform and add to phase A/B. Continue mixing until uniform. Add phase D to batch. Increase mixing speed as needed to maintain a good vortex. Remove from heat.
