A water-in-silicone oil emulsion contains (i) in the range from 0.1 to 25 % by weight of particles of metal oxide having a median particle volume diameter in dispersion in the range from 18 to 32 nm, (ii) 5 to 60 % by weight of silicone oil, and (iii) greater than 20 % by weight of water. The metal oxide particles are preferably incorporated into the emulsion in the form of an aqueous dispersion. The emulsion exhibits good skin feel, effective UV protection, stability and improved transparency.
