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' of Composition (A) filled in one chamber to a storage modulus G′ 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.
