Patent ID: 7495031

Claim:
A process for producing an emulsion, comprising adding a mixture ( 1 ) comprising a water-soluble inorganic salt (a) which comprises potassium carbonate and/or an aqueous solution comprising the potassium carbonate to a mixture ( 2 ) comprising a surfactant (b) which comprises a mixture of anionic surfactant and nonionic surfactant, a surfactant-emulsifying agent (c) which comprises a copolymer of polyethylene glycol monomethacrylate and methacrylic acid for emulsifying the surfactant (b), and a hydrophilic powder (d) which comprises a zeolite, and mixing mixtures ( 1 ) and ( 2 ) to emulsify the surfactant (b), wherein surfactant-emulsifying agent (c) is such that when a composition containing 20 weight % of the surfactant (b), 30 weight % potassium carbonate, 5 weight % of the surfactant-emulsifying agent (c) and the balance, water, is shaken in a transparent bottle for 1 minute at room temperature and left at room temperature for 3 minutes, the composition remains opaque in an emulsified state.
