A method for producing microballoons consisting of a polyurethane (urea) produced by an interfacial polyaddition reaction method with a W/O emulsion and having excellent dispersibility is provided. Specifically, a method for producing microballoons, characterized by forming a microballoon dispersion liquid consisting of a polyurethane (urea) by an interfacial polyaddition reaction method with a W/O emulsion and then treating the dispersion liquid with a solution containing a monofunctional active hydrogen compound containing only one active hydrogen group selected from an amino group and a hydroxyl group is provided.

Provided are: a glycerin dispersion in which the dispersibility and storage stability of a hydrophobized inorganic powder are improved; and a cosmetic containing the glycerin dispersion. A glycerin dispersion containing a hydrophobized inorganic powder, in which an inorganic powder is used as a base and hydrophobicity is imparted by coating the inorganic powder with an organic surface treatment agent, a polyglycerin-based nonionic surfactant, and glycerin is provided.
