The present invention is hydrophilized powder, wherein the powder is surface treated with polyether-modified silicone having a hydrolyzable silyl group according to the formula (1), R<1>aR<2>bR<3>cSiO(4-a-b-c)/2 (1) wherein R<1 >is an organic group having 1 to 80 carbon atoms, R<2 >is a polyether group according to the following formula (2), -CdH2d-O-(C2H4O)e(C3H60)fR<4> (2) wherein d, e, and f are integers with 0<=d<=15, 1<=e<=50, and 0<=F&LE;50, R<3 >is a silyl group having a hydrolyzable group according to the general formula (3), -CdH2d-SiR<1>g(OR<5>)3-g (3) wherein d is as define above and 0<=g<=2, and 0.5<=a<=2.5, 0.1<=b<=1.5, and 0.01<=c<=1.5. The invention also provides a composition comprising the powder, an aqueous dispersion comprising the powder, and their application in cosmetics, coatings, and inks.
