摘要:
The present application relates to a process for preparing a personal care composition by combining a fatty amphiphile above its melt temperature and a surfactant in a weight ratio from 0.1:1 to 0.99:1 to form a gel network premix contacting the gel network premix with a shearing device, cooling the gel network premix to a temperature below the melt temperature of the fatty amphiphile and adding the cooled premix to personal care components to form the personal care composition.
摘要:
The proposed process of the present application passes a concentrated surfactant in a lamellar phase though a high-shear device diluting the concentrated surfactant in a lamellar phase to an isotropic phase without encountering the highly viscous middle phase.

An extrusion/coating die. The die has an internal cavity and one or more static mixers in the die cavity. The static mixer fills the die cavity at its respective cross section. The die may also have one or more auxiliary inlets for separately admitting material/energy to the die.
摘要:
A method of making a stable detersive surfactant containing personal care composition comprising the steps of emulsifying a stabilizing agent in the presence of anionic surfactant to form an emulsion containing droplets having a particle size of from about 0.1 to about 10 um. These particles are then cooled to form a stabilizing premix at a rate of about 10 to about 1000 C/min to form crystals from the droplets, the crystals having a maximum dimension of about 0.1 to about 3 um. These crystals are then added to a detersive surfactant containing personal care composition to increase stability.
