Abstract:
1. A gel consisting of: from 5 to 25 wt % of an inorganic viscosity modifier relative to the total weight of the gel; a surfactant in an amount ranging from 0.01 to 0.1 wt % relative to the total weight of the gel, the value 0.1 wt % not being inclusive; from 0.5 to 7 mol/l of gel of an inorganic acid, of a mixture of inorganic acids, of an inorganic base or of a mixture of inorganic bases; optionally from 0.05 to 1 mol/l of gel of an oxidizer having a standard redox potential E water, wherein the surfactant is chosen from the group consisting of alcohol alkoxylates, alkylaryl sulphonates, alkylphenol ethoxylates, block polymers based on ethylene oxide or propylene oxide, ether phosphates, glycerol esters, imidazolines, quats, alkanolamides, amine oxides, and mixtures thereof, and wherein said gel results, after complete drying from 2 to 72 hours, at a temperature between 10° C. and 30° C. and a relatively humidity between 20 and 70%, in a solid dry residue.
