Procedure

Add deionized water with propylene glycol, disodium EDTA and Phenonip to main beaker and begin heating to 75-80°C with low homogenizer mixing (2000-3000 rpm). Once dispersed, sprinkle in Carbopol 940 and homogenize at low to moderate speed (2000-3000 rpm) until hydrated. Then add Dermacryl AQF to main beaker and mix until dispersed. Add phase B ingredients to side beaker and begin heating to 75-80°C with propeller mixing at 300 rpm. Once phases A and B reach desired temperatures, add phase B to phase A with moderate homogenization (4000 rpm) mixing for 10 min. at 75-80°C. Begin cooling batch to 45°C. Pre-mix phase C and add to main beaker once temperature gets below 45°C. Homogenize (4000 rpm) for 5 min. until dispersed and uniform. Add phase D to main beaker and homogenize (4000 rpm) until fully dispersed and uniform. Switch batch to sweep blade and mix at 20 rpm while cooling to 25°C.
