A powder-containing composition contains from 0.5% by mass to 22% by mass of a first powder which is a nonspherical powder having a hydrophobic particle surface, from 6% by mass to 25% by mass of a liquid-state polyol, 50% by mass or greater of water, and from 3% by mass to 12% by mass of a liquid-state oily component. A content of a second powder which is a spherical powder is 1.5 parts by mass or less relative to 1 part by mass of the first powder. A content of a surfactant is 0.5% by mass or less relative to the mass of the powder-containing composition.
