Zusammenfassung:PROBLEM TO BE SOLVED: To provide a preparation method of an emulsion excellent in usability and detergency, whereby preservation stability of a solid particle is markedly improved. SOLUTION: In the preparation method of the emulsion containing a water-soluble polymer compound (e) wherein a hydrophilic monomer-derived structural unit accounts for ≥90 mass% of the molecule, a water-soluble inorganic salt (d) and/or its aqueous solution (2) are added to and mixed with an aqueous solution (1) containing a surfactant (a), a surfactant emulsifier (b) (other than the water-soluble polymer compound (e)) for emulsifying the surfactant (a) and a hydrophilic powder (c) at a liquid temperature within the range of 5-25°C to emulsify the surfactant (a).
