Abstract
Disclosed are oral care compositions, for example dentifrice compositions, comprising an oral care composition comprising an orally acceptable vehicle, metal oxide particles having an average particle size of no greater than a dentin tubule and at least one amino acid capable of chelating the metal oxide. The composition may comprise a polymeric adherent material for adhering the metal oxide particles in the dentin tubule. The metal oxide particles have a median particle size of 5 microns or less, and may comprise zinc oxide.
Claims31
An oral care composition comprising:
- an orally acceptable vehicle;
- a source of metal oxide particles, wherein said metal oxide particles have a median particle size of from 1 to 7 microns;
- one or more amino acids capable of chelating said metal oxide particles, wherein the metal oxide comprises at least one metal oxide selected from, stannous oxide, calcium oxide, copper oxide and or a mixture thereof;
- and
- further comprising a polymeric adherent material.
