ABSTRACT:
The invention relates to a particulate silica or particulate titania which is treated with a cyclic polysiloxane having the formula ##STR1## in which Me represents a methyl radical and R is an alkyl group having 2 to 12 carbon atoms, The treated particles can be uniformly dispersed in a non-polar organic medium to provide a system having greater stability than similar prior art dispersions,
