A method for producing a personal hygiene composition comprising: a) forming, in a mixing tank, premix having a viscosity less than a packaged personal hygiene composition, wherein the viscosity of the premix in the mixing tank is in the range of 0.01 Pa.s to 10 Pa.s measured at 10 s-1; b) transfer the premix from the mixing tank to a high energy dispersion device suitable for transferring an energy density between 0.5 KW / Kg / s to 11 KW / Kg / s; c) add rheology modifier to the premix; d) deaerate the premix; e) add a surfactant to the premix after deaeration to complete the formula; and f) pack the premix to produce a personal hygiene composition. |
