EXAMPLES The present invention will be specifically described below with reference to examples and comparative examples, but the present invention is not limited to the following examples. In addition, all% in each example are weight%.

[Examples 1 to 6, Comparative Examples 1 to 4] Method for evaluating cleaning power The B value (B1) of an apatite plate (diameter 7 mm, thickness 3.5 mm) having coffee and black tea extract adhered to the surface was determined. Measured with a color difference meter, immersed in a dispersion of 5 g of dentifrice having the composition shown in Table 1 and 15 g of pure water for 24 hours, and then again B value (B2)
Is measured.

The cleaning power is determined by the following equation and is scored.

Cleaning power (ΔB value) = {(B1-B2) / B1} × 100

[0024]

[Table 1]

In the above experiment, the cleaning power was evaluated without brushing. As is clear from the results shown in Table 1, no cleaning power was obtained with a composition containing no silver nitrate or silver acetate (Comparative Example). 1, 2, 3). Further, even in a composition containing 1% of sodium hydrogencarbonate, if the amount of silver nitrate is less than 0.001%, no cleaning power can be obtained (Comparative Example 4).

On the other hand, it was recognized that a composition containing 0.5% or more of sodium hydrogencarbonate or sodium hydrogensulfate and 0.1% or more of silver nitrate or silver acetate can obtain excellent cleaning power (Examples). 1-5).
