Abstract
A powder aerosol composition is obtained by first preparing a suspension consisting of a hydrophobic powdered substance having its pH adjusted to fall within the range 5 to 9, alcohol and water, adding, if required by the desired powder system, an intentional medicine and other auxiliary agents to the suspension and mixing the suspension with 5 to 40 wt % of a propellant in an aerosol container. The thusly produced composition has an improved safety in application, prevents flying properties, has an improved adhesion to the skin and can be produced inexpensively. Thus, the composition is best suited for use in applications such as baby powder, dry shampoo, water-eczema remedy and antiperspirant.
