Procedure
Heat phase A to 85°C while stirring. Heat phase B to 80°C and add to phase A while stirring and homogenizing the emulsion. Cool down the emulsion to 55°C and add phase 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. Cool down further to 35°C and add phase D together with the perfume oil. It is highly recommended to remove oxygen as much as possible by using vacuum while producing the product. Homogenize thoroughly and then with continued mixing cool down to ambient temperature.
