Procedure
Heat phase A to 85°C and stir until homogeneous. Heat phase B to 85°C and add to part A under agitation. Cool down the emulsion to 55°C and add phase C. When everything is homogenous add phase D pre-heated to 50°C. Be sure that the pH of Parsol HS solution is 7.0. If traces remain, add small quantities of the used neutralizing base until the particles are dissolved. Homogenize thoroughly and then with continued mixing cool down to ambient temperature. It is generally recommended to use vacuum while producing the emulsion.
