摘要： The invention relates to a solid material, preferably in powder form, useful, in particular in the form of a gel-type hydrogen peroxide and/or acid source, wherein said material comprises intimately associated (A) a gelling agent which forms a gel in the presence of stirred water and is embodied in the form of hydrophilic silica, (B) a substance which is harmful in an aqueous solution and is selected from an assembly formed by (B1) a hydrogen peroxide, (B2) acids, (B3) the mixtures thereof and (C) an agent for homogeneously dispersing the substance (B) in the gel produced by bringing into contact (i) the mixture of (A) and (B) or (ii) said solid material with the stirred water. A method for the preparation and the use of said material is also disclosed.
