The present invention provides a dispersible powder comprising a powder that has been treated using a surface treatment agent. The dispersible powder is characterized by: the surface treatment agent being selected from organopolysilixane surfactants having a weight average molecular weight of 300–20,000; the organopolysilixane surfactants having, as a hydrophilic group, at least one organic group selected from a glycerine group, an amino group, a carboxyl group, and sugar residues; the weight ratio between the hydrophilic group and the total organopolysilixane surfactant being no more than 4.0, when the hydrophilic group is 1; and not having a polyoxyalkylene group. As a result, a dispersible powder can be provided that has excellent dispersibility in aqueous media and oil and high dispersion stability.
