Oral composition

An oral composition comprising the following ingredients (A), (B), (C), and (D):

• (A) 0.005 mass % or more and 2 mass % or less, in terms of fluorine atoms, of one or more fluoride ion-supplying compounds selected from the group consisting of sodium fluoride, ammonium fluoride, potassium fluoride, sodium monofluorophosphate, and tin fluoride;
• (B) 4 mass % or more and 30 mass % or less of a higher alcohol having 12 or more and 22 or less carbon atoms comprising (b1) cetanol and (b2) stearyl alcohol;
• (C) 0.1 mass % or more and 10 mass % or less of a surfactant comprising one or more selected from the group consisting of (c1) a nonionic surfactant selected from the group consisting of sorbitan fatty acid ester and polyoxyethylene sorbitan fatty acid ester and (c2) an anionic surfactant being fatty acid having 12 or more and 22 or less carbon atoms or a salt thereof;
• and
• (D) water,
• wherein:
• the content of the ingredient (c1) is 0.05 mass % or more;
• a mass ratio of the content of the ingredient (A) in terms of fluorine atoms to the content of the ingredient (B), (A)/(B), is 0.001 or more and 0.2 or less;
• the molar amount of (E) a polyvalent metal compound other than the ingredient (A) is less than 0.1-fold the molar amount of the ingredient (A);
• wherein,
• when the ingredient (C) does not contain the ingredient (c2), a mass ratio of the content of the ingredient (B) to the content of the ingredient (c1), (B)/(c1), is 1 or more and 10 or less;
• when the ingredient (C) contains both the ingredient (c1) and the ingredient (c2), a mass ratio of the content of the ingredient (B) to the content of the ingredient (c1), (B)/(c1), is 1 or more and 10 or less and a mass ratio of the content of the ingredient (B) to the content of the ingredient (c2), (B)/(c2), is 2 or more and 180 or less.
