To prepare the dispersing phase, the manufacturing facility must provide a method of dosing the components (by weight or by volume), mixing and diluting, if necessary, and heating of water. Dosing of components in the preparation of the soap solution may be controlled by simple graduated vessels or highly accurate load cells and mass flow meters. Some plants are equipped with a pH meter to be able to continuously check compliance of the pH indicated to that provided by formulation during the dispersing phase production and subsequent emulsion production.
