摘要 |
Pulverulent mixture comprising hydrogen peroxide and hydrophobized, pyrogenically prepared silicon dioxide powder, wherein the hydrophobized silicon dioxide powder has a methanol wettability of at least 40 and is present to the extent of less than 9 wt. %, based on the total weight, and the content of hydrogen peroxide, based on the total weight, is between 10 and 50 wt. % It is prepared by a process in which hydrophobized silicon dioxide powder with a methanol wettability of more than 40 is treated with an aqueous hydrogen peroxide solution at temperatures of not more than 70° C. It can be used in detergents, in cleaning compositions and in skin and hair treatment compositions. |
