Beschreibung
Zusammenfassung:	The present invention has an object to provide a high concentration dispersion of zinc oxide or titanium dioxide which is free of volatile silicones, as well as a cosmetic composition which gives little sticky feel after spreading on the skin. The present invention relates to a dispersion which contains: zinc oxide or titanium dioxide; an isoparaffin having the average polymerization degree of 3 to 10; and a polyether-modified silicone having an HLB value of 2 to 5, as a dispersant; the amount of the zinc oxide or titanium dioxide being not less than 60% by mass of the whole amount of the dispersion.
