摘要：
The present invention relates to non-aqueous emulsions stabilised by silica particles and to processes for making them. The invention further comprises:a particle stabilized oil-in-polar (o/polar o/p) emulsion comprising:a) a dispersed oil phase,b) a continuous polar phase substantially free of water,c) a particulate solid which is a silica particle dispersant possessing surface silanol groups (SiOH) sufficient to stabilize the emulsion, and where the emulsion is substantially free of emulsifiers, surfactants； and wherein the oil phase (a) is dispersed as discontinuous droplets in the polar phase (b)； the silica particle dispersant (c) is absorbed on the surface of the oil phase (a)； and the silica particle dispersant (c) is partially wetted by the polar phase (b).
