Procedure
Phase A: Disperse Natrosol Plus CS 330 and glycerin in water. Mix until Natrosol Plus is fully dispersed (Note: Heating to 60-65°C will speed up hydration process. If heat is used, once Natrosol  Plus is fully hydrated, remove batch from heat and continue adding ingredients while batch cools.) Add Carbopol* Aqua CC Polymer to phase A.  Mix until uniform.     Add glycolic acid to batch. Mix until uniform. As batch begins to thicken, increase speed to maintain a good vortex. Add polyethylene to batch. Mix until uniform. Once  batch has cooled to ~ 25 °C (if heat was used), add phase  C ingredients one at a time with good mixing in between additions. Mix until uniform. Adjust deionized water for any water loss. (If heat was used in processing).
