ABSTRACT:
A method of manufacturing sulfated cellulose using any of the Lewis base-SO.sub.3 complexes as a sulfating agent, which characteristically consists in thermally activating cellulose prior to its sulfation in tertiary amines or a mixture of tertiary amines and amine hydrochlorides, thereby enabling alkali metal salts of cellulose sulfate to be favorably accepted as a binder for dentrifice compositions.
