Abstract
A toothpaste is provided. The toothpaste at least includes 5% to 20% of hydrated silica and 5% to 15% of zeolite by a mass fraction. An average particle size of the hydrated silica is defined as R1, a Brinell hardness of the hydrated silica is defined as H1, an average particle size of the zeolite is defined as R2, and a Brinell hardness of the zeolite is defined as H2. R1, R2, H1, H2 meet following relationships: 20 μm≤R1≤40 μm, 1 μm≤R2≤10 μm, 5≤R1/R2≤20, 2.5 HB≤H1≤3.5 HB, 4.0 HB≤H2≤6HB, and 1.3≤H2/H1≤2.
