Procedure
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 water into main vessel. Add if necessary NaOH 18% to bring pH above 7. Slowly add hydrolyzed soy protein. When totally dissolved slowly sift in Jaguar C17 and mix until uniform (about 15 min). Charge Miracare SLB-365/N and mix until uniform (about 15 min). Add the Mirasil DME-2 KCG, fragrance and mix until totally uniform (about 30 min).Charge sodium chloride solution and sodium benzoate into main vessel and mix until uniform (about 15 min). Adjust pH of the system to 4.7 with citric acid solution (50% aq.), and mix for one hour. After one hour mixing, slowly add the satin pearl mica, and mix with moderate speed to disperse the product.
