摘要：
A process for preparing an aqueous suspension of a water-soluble carboxymethylcellulose salt, characterized in that it comprises dissolving in water at least 33 % by weight of potassium carbonate and then dispersing therein with agitation at least 8 %, based on the weight of the total resultant aqueous suspension, of the carboxymethylcellulose salt, the aqueous suspension made by the said process, and the use of the aqueous suspension to prepare an aqueous solution of dissolved water-soluble carboxymethylcellulose salt, are disclosed.
