Abstract

Provided is an oral composition that has excellent stability over time although a hydrocarbon oil is contained therein. Specifically provided is an oral composition comprising a hydrocarbon oil, a polyhydric alcohol, and a surfactant, the oral composition comprising (i) glycerol, and a polyglycerol fatty acid ester and/or an alkyl glucoside, (ii) propanediol, and a polyoxyethylene hardened castor oil and/or a polyoxyethylene hardened castor oil fatty acid ester, (iii) butylene glycol, and a polyoxyethylene alkyl ether and/or a polyoxyethylene hardened castor oil fatty acid ester, or (iv) polyethylene glycol and a polyoxyethylene hardened castor oil fatty acid ester.

Claims (42)

1 . An oral composition comprising a hydrocarbon oil, a polyhydric alcohol, and a surfactant, the oral composition comprising:

(i) propanediol, and a polyoxyethylene hardened castor oil,

(ii) butylene glycol, and a polyoxyethylene alkyl ether and/or a polyoxyethylene hardened castor oil fatty acid ester, or

(iii) polyethylene glycol and a polyoxyethylene hardened castor oil fatty acid ester,

wherein the oral composition has a water content of 5 mass % or less, and

wherein a content mass ratio of the polyhydric alcohol and the hydrocarbon oil measured as (mass of polyhydric alcohol/mass of hydrocarbon oil) is 0.1 to 1.1.

2 . The oral composition according to claim 1 , which is a non-aqueous composition.

3 . The oral composition according to claim 1 , which is not phase-separated after being allowed to stand at 25° C. for one week after preparation.

4 . The oral composition according to claim 1 , wherein the hydrocarbon oil is paraffin.

5 . The oral composition according to claim 1 , which is used with a toothbrush composition.

6 . The oral composition according to claim 1 , which comprises

(i) propanediol and a polyoxyethylene hardened castor oil.

7 . The oral composition according to claim 1 , which comprises

(ii) butylene glycol, and a polyoxyethylene alkyl ether and/or a polyoxyethylene hardened castor oil fatty acid ester.

8 . A composition that is a carrier for an oral composition and comprises a hydrocarbon oil, a polyhydric alcohol, and a surfactant, the composition comprising:

(i) propanediol, and a polyoxyethylene hardened castor oil,

(ii) butylene glycol, and a polyoxyethylene alkyl ether and/or a polyoxyethylene hardened castor oil fatty acid ester, or

(iii) polyethylene glycol and a polyoxyethylene hardened castor oil fatty acid ester,

wherein the composition has a water content of 5 mass % or less, and

wherein a content mass ratio of the polyhydric alcohol and the hydrocarbon oil measured as (mass of polyhydric alcohol/mass of hydrocarbon oil) is 0.1 to 1.1.

9 . The composition according to claim 8 , which comprises

(i) propanediol and a polyoxyethylene hardened castor oil.

10 . The composition according to claim 8 , which comprises

(ii) butylene glycol, and a polyoxyethylene alkyl ether and/or a polyoxyethylene hardened castor oil fatty acid ester.

11 . The composition according to claim 8 , which is a non-aqueous composition.

12 . The composition according to claim 8 , wherein the hydrocarbon oil is paraffin.

13 . The composition according to claim 8 , which is used with a toothbrush composition.

14 . An oral composition comprising a hydrocarbon oil, a polyhydric alcohol, and a surfactant, the oral composition comprising:

(a) propanediol and a polyoxyethylene hardened castor oil fatty acid ester,

(b) propanediol, a polyoxyethylene hardened castor oil, and a polyoxyethylene hardened castor oil fatty acid ester, or

(c) polyethylene glycol and a polyoxyethylene hardened castor oil fatty acid ester,

wherein the oral composition has a water content of 5 mass % or less, and

wherein a content mass ratio of the polyhydric alcohol and the hydrocarbon oil measured as (mass of polyhydric alcohol/mass of hydrocarbon oil) is 0.1 to 1.1.

15 . The oral composition according to claim 14 , which comprises

(a) propanediol and a polyoxyethylene hardened castor oil fatty acid ester.

16 . The oral composition according to claim 14 , which comprises

(b) propanediol, a polyoxyethylene hardened castor oil, and a polyoxyethylene hardened castor oil fatty acid ester.

17 . The oral composition according to claim 14 , which comprises

(c) polyethylene glycol and a polyoxyethylene hardened castor oil fatty acid ester.

18 . The oral composition according to claim 14 , which is a non-aqueous composition.

19 . The oral composition according to claim 14 , wherein the hydrocarbon oil is paraffin.

20 . The oral composition according to claim 14 , which is used with a toothbrush composition.
