摘要：The invention concerns a process for producing a water-in-oil emulsioncomprising mixing an oil dispersion of particles of a metallic oxide having a primaryparticle size less than 0.2 micron with one or more emulsifiers and an aqueous phase. Themethod enables the production of such emulsions containing relatively small quantitiesof emulsifiers and a novel emulsion made available by the invention contains less than 1%by weight of emulsifiers, 10 to 60% by weight of an oil phase and at least 40% by weightof an aqueous phase. The emulsions so formed are useful in preparing UV absorbingcompositions such as sunscreens, skin protectants, moisturisers and after-sun lotions.
