Semi-continuous feed production of liquid personal care compositions

摘要: A mixing assembly (10) for use in a semi - continuous process producing liquid personal care compositions, such as shampoos, includes main feed tube (12) carrying base of the composition to be produced, plurality injection tubes (14, 16, 18, 20, 22) selective fluid communication with (12), and an orifice provided wall at end downstream tubes. The which is curved (e.g., semispherical) entry surface on upstream or inlet side orifice, elliptical) exit outlet orifice. may have rectangular elliptical shape. By maintaining symmetry respect leveraging delay between introduction dosed modules increased viscosity, effective achieved minimal energy.
