摘要：The invention concerns an aqueous composition associating at least a block copolymer (A) comprising, at a given pH, pH0, of the composition, ranging between 1 and 14, at least two blocks bearing at least two ionic charges of the same type, with at least a compound (B) bearing one or more ionic charge(s) opposite to that of said blocks in the same pH conditions; the compound (B) being selected among ions bearing at east two ionic charges, surfactants bearing at least an ionic charge, oligomers and/or polymers bearing at least two ionic charges and/or the mineral particles bearing at least two ionic charges; the block copolymer (A) content being such that the viscosity of the composition is higher by three times, preferably by not less than ten times, than that of an aqueous solution of block copolymer (A) and than that of an aqueous solution of compound (B), at pH0, and in the same temperature and concentration conditions. The invention is in gel form before and during use.
