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).
