Claim:
An oral composition comprising 0.5 to 10% by weight of said oral composition of an abrasive precipitated silica having a 50 percentile (d 50 ) of particle diameter being 5 μm or less, a 90 percentile (d 90 ) of particle diameter being 15 μm or less and an RDA value of 120 or more, and 0.01 to 5% by weight of said oral composition of at least one of sulfosuccinate surfactants represented by general formula (1): wherein either X 1 or X 2 is R 1 —(AO) n — or R 1 CO—B—(AO) n — and the other is M 2 O—; M 1 and M 2 are the same or different and each represent hydrogen, alkali metal, alkaline earth metal, ammonium, or alkanolamine; R 1 is alkyl or alkenyl with 8 to 22 carbons; AO is oxyalkylene with 2 or 3 carbons and the average number of moles of AO addition polymerization, “n”, is 0 to 20; and B is —NH— or a monoalkanolamine residue with 2 or 3 carbons.
