Abstract:
A silicone oil emulsion comprising cross-linked silicone particles which have an average particle diameter of 0.1 to 100 .mu.m, the crosslinked silicone particles being contained in silicone oil drops having an average diameter of 0.5 to 500 .mu.m, the silicone oil drops containing the cross-linked silicone particles being dispersed in water, the diameter of the cross-linked silicone particles being smaller than the diameter of the silicone oil drops, the cross-linked silicone particles being prepared by a hydrosilylation cross-linking reaction or a condensation cross-linking reaction between (i) an organopolysiloxane having in its molecule at least two alkenyl groups and an organopolysiloxane having in its molecule at least two silicone-bonded hydrogen atoms, or (ii) an organopolysiloxane which contains a hydrolyzable group and a silane-type cross-linking agent having a hydrolyzable group, respectively.
