Tooth agent

Abstract

A toothpaste filled in a container which has two chambers and is capable of simultaneously discharging two different compositions filled respectively in the two chambers when the main body of the container is pressed, wherein a ratio of a storage modulus G A ′ of Composition (A) filled in one chamber to a storage modulus G B ′ of Composition (B) filled in the other chamber falls within a range of from 0.6 to 1.4. By controlling the ratio, it is possible to stably discharge from the container storing these two compositions separately predetermined amounts of these two compositions which will otherwise cause a time-dependent change if they are pre-mixed thereby failing to attain the purpose of their addition.

1 . 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, 
 wherein a ratio of the storage modulus G A ′ of one composition (A) in one chamber to the storage modulus G B ′ of the other composition (B) in another chamber falls within a range of from 0.6 to 1.4.    
     
     
         2 . The toothpaste of  claim 1 , wherein the ratio G A ′/G B ′ is a ratio at tanδ=1.  
     
     
         3 . The toothpaste of  claim 1 , wherein at least one of the compositions contains at least one of sodium carboxymethylcellulose and silica.  
     
     
         4 . The toothpaste of any one of  claims 1  to  3 , wherein composition (A) contains a calcium ion-supplying compound, while composition (B) contains a fluoride ion-supplying compound.  
     
     
         5 . The toothpaste of  claim 4 , wherein composition (A) contains granules.
