Procedure
(Use strong mixing, without aeration, throughout.) To main vessel add 1. Start mixing and begin heating to 45-50°C. Disperse 3 in 2 with mixing, heating as necessary to achieve solution. When 3 is fully dissolved, slowly add this premix to the main vessel with water at 45-50°C. With rapid but smooth agitation, very slowly add 4 to the main vessel (when an eductor is available, withhold some water for use with the eductor to incorporate 4). Continue heating this water phase to 75-80°C. Meanwhile, in a separate vessel combine 6 through 10 and heat this oil phase to 70-75°C and mix to make uniform and prevent overheating. When the water phase is at 75-80°C, with the carbomer fully dispersed (no “fish eyes”), slowly add 5 to the main vessel, maintaining strong mixing without aeration. After several minutes, when the batch is uniform, slowly add the uniform, 70-75°C, oil phase. Maintain the batch at 75°C for 20 minutes (until a uniformly small particle size emulsion is achieved) and then start cooling. At 45°C add fragrance and approved colorants as desired. Stop cooling and mixing when uniform and at desired filling temperature. Perform final quality assurance checks.
