To prepare such a formula, low rpm mixing (typically 150 rpm) is recommended in order to properly structure the system and minimize air entrapment. Also, the agitation system has to be chosen carefully so that to ensure good recirculation of the product. The use of paddle stirrers, impellers or anchors is recommended. The blending procedure is the following (the mixing rate is set at 150 rpm except otherwise specified). Charge phase A into main vessel and begin mixing. Charge phase B and mix with phase A until uniform (about 15 min). Begin heating phase A and B batch to 50-55°C. In a separate vessel, melt phase C to 50-55°C. Once both the phase A/B and phase C vessels are at the same temperature, add melted phase C to the main vessel with increased mixing speed. Mix and heat at temperature until uniform for 10-15 minutes. Then, discontinue heating. In a separate vessel, premix phase D into phase E. Once phase D is fully dispersed, add to the main batch and mix until uniform. At 45°C or below, add phase F to the main vessel to adjust pH of the system to 5.0u20135.5. Add phase G and mix until uniform. Charge phase H into main vessel and mix until uniform (about 30-45 min). Premix phase I into phase J, and once dissolved, add to main batch and mix until uniform.
