Granular peroxygen bleaching and laundering compositions containing a percarbonate as a source of available oxygen are stabilized by the addition of from 0.1 to 2.0 percent of a particulate siliceous matter such as amorphous silica. To prevent caking and promote flowability of the compositions, from 0.05 to 1.0 percent corn starch, diethyl phthalate or mixtures thereof is included. |
