Abstract

A decontamination gel is provided consisting of a colloidal solution comprising 0.1% to 30% by mass, preferably 0.1% to 25% by mass, still more preferably from 5% to 25% by mass, even more preferably 8% to 20% by mass, based on the mass of the gel, of at least one inorganic viscosifying agent; 0.1 to 10 mol/L of gel, preferably 0.5 to 10 mol/L of gel, still more preferably 1 to 10 mol/L of gel of at least one active decontamination agent; 0.01% to 10% by mass, preferably 0.1% to 5% by mass based on the mass of the gel of at least one mineral pigment; optionally, 0.1% to 2% by mass based on the mass of the gel, of at least one surfactant; optionally, 0.05% to 5% by mass, preferably 0.05% to 2% by mass, based on the mass of the gel, of at least one super-absorbent polymer; and the balance of solvent.
