Beschreibung
Zusammenfassung:	The present invention is directed to a method of producing a toothpaste having two compositions which are filled separately in two chambers of a container capable of simultaneously discharging therefrom these two compositions when the body of the container is pressed. At least one of the compositions contains at least one of sodium carboxymethyl cellulose and/or silica in which composition two kinds of silica different in an oil absorption amount and/or two kinds of sodium carboxymethyl cellulose different in degree of etherification may be used. Moreover, a ratio of storage modulus G' A , measured by a rheometer, of one of the composition A in one chamber to the storage modulus G' B , measured by a rheometer, of the other composition in another chamber at tan ´=1 falls within a range of from 0.8/1 to 1/0.8.
