Hydrogen peroxide activation.

摘要

The bleaching performance of hydrogen peroxide or persalts developing it in situ is markedly lower at lower washing temperatures from ambient to 60°C than at hot washing temperatures of around 90°C or above.

The present invention relates to compositions and processes employing a minor amount of mixed oxides of calcium, barium or strontium with manganese which activate hydrogen peroxide bleaching and washing of stains at lower wash temperatures in spite of the fact that the compounds are substantially water-insoluble.
