Process for preparing a solution of a polysaccharide or polysaccharide ether having a viscosity of 1,000 mPa.s or less comprising adding to an aqueous medium a polysaccharide or polysaccharide ether and an alkaline depolymerization agent. Also disclosed is a solid composition comprising a polysaccharide ether and an alkaline depolymerization agent. Preferably, the depolymerization agent is selected from the group consisting of sodium percarbonate, sodium perborate, carbamide peroxide in combination with a base, sodium persulfate in combination with a base, 3-chloroperoxybenzoic acid in combination with a base, and mixtures thereof.

Processus de préparation d'une solution de polysaccharide ou d'éther de polysaccharide possédant une viscosité de 1.000 mPa, voire inférieure, qui consiste à ajouter à un milieu aqueux un polysaccharide ou un éther de polysaccharide et un agent de dépolymérisation. Cette invention concerne aussi une composition solide comprenant un éther de polysaccharide et un agent de dépolymérisation. Cet agent de dépolymérisation est, de préférence, sélectionné dans le groupe constitué de percarbonate de sodium, de perborate de sodium, de peroxyde de carbamide en combinaison avec une base, de persulfate de sodium en combinaison avec une base, d'acide 3-chloropéroxybenzoïque en combinaison avec une base et de mélanges de ceux-ci.
