Procedure
To the main vessel, add deionized water, Dissolvine NA2-S chelate and propylene glycol. Mix until dissolved using a propeller with moderate speed. Sprinkle in Carbopol 940, and mix until dispersed. Then add Flexan II polymer and Structure XL starch, one at a time. Ensure that the polymers are hydrated and homogeneously dispersed. Begin to heat phase A to 75-80°C. Combine phase B in a side kettle and mix with a propeller at moderate speed, heating to 75-80°C. Slowly add phase B into phase A under a homogenizer with moderate speed. Emulsify for 1 minute. Switch the batch to propeller, and begin cooling the batch to 65°C while mixing. Neutralize the batch with triethanolamine. Mix moderately for 10 minutes until uniform. Add the remaining ingredients from phase C, and mix until homogeneous. Continue to cool the batch to 45°C. Add phase D at low speed under the homogenizer. Move the beaker around to allow full incorporation of the starches, approximately 10 minutes. Add phase E, and mix until homogeneous. Switch the batch to a sweep blade, and cool to room temperature. Drop the batch.
