Process for increasing the bleaching efficiency of an inorganic persalt or of hydrogen peroxide

摘要

A process for increasing the bleaching efficiency of an inorganic persalt or hydrogen peroxide by adding to said persalt or H2O2 an activating agent. The activating agent is an acetylated gluconic acid derivative, such as N-methyl-N-acetyl pentaacetyl gluconamide, N-methyl-N-acetyl pentaacetyl gluconamide or tetraacetyl gluconolactone. The invention also relates to the acetylated gluconic acid derivatives themselves.
