<P>PROBLEM TO BE SOLVED: To provide a spray container containing powder-containing cosmetics, which prevents clogging due to powder so as to obtain an excellent spray state even when compressed gas is used. <P>SOLUTION: The spray container containing the powder-containing cosmetics is obtained by filling the spray container having a spray button 1 with a mechanical break-up mechanism with the powder-containing cosmetics and compressed gas as contents. In the spray button 1, the bore diameter Da of a spray port 21, the diameter D of a turning chamber 20, the width Dd of a spray groove 17 in a connection part between the spray groove 17 and the turning chamber 20, and a length L from the front end surface 24 of the spray port to the rear end surface 25 of the turning chamber satisfy the following relations: (i) 3<D/Da; (ii) 7≤D/Dd; (iii) 3≤D/L. The powder-containing cosmetics contains: (A) component, a powder; (B)component, a nonionic surfactant; (C) component, ethanol; and (D) component, water, where a mass ratio to be expressed by the (A)component/the (B) component is 0.1 to 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
