wherein the foamability of the cleansing composition comprising the mixture of internal olefin sulfonates is better than if the mixture of internal olefin sulfonates was replaced with secondary sodium alkyl sulfonate, and
wherein the foam dissipation property of the cleansing composition comprising the mixture of internal olefin sulfonates is better than if the mixture of internal olefin sulfonates was replaced with sodium α-sulfonate.

2. The cleansing composition according to claim 1 , wherein a content of the internal olefin sulfonate in which a sulfonate group is present at a C-2 position in the internal olefin sulfonate having 12 and 14 carbon atoms is 28% by mass or less.

3. The cleansing composition according to claim 1 , wherein a mass ratio of a content of a hydroxy form in the internal olefin sulfonate having 12 and 14 carbon atoms to a content of an olefin form in the internal olefin sulfonate having 12 and 14 carbon atoms, (hydroxy form/olefin form), is from 50/50 to 100/0.

4. The cleansing composition according to claim 1 , wherein, in the internal olefin mixture, a content of a raw material internal olefin in the internal olefin sulfonate mixture is less than 5.0% by mass with respect to the amount of the internal olefin sulfonate.

5. The cleansing composition according to claim 1 , wherein a the content of an inorganic compound in the internal olefin sulfonate mixture is less than 7.5% by mass with respect to the amount of the internal olefin sulfonate.

6. The cleansing composition according to claim 1 , wherein the internal olefin sulfonate mixture is obtained by sulfonating a raw material containing a raw material internal olefin, followed by neutralization and then hydrolysis, with a content of the raw material internal olefin in which a double bond is present at a C-2 position being from 15 to 40% by mass.

7. The cleansing composition according to claim 1 , wherein a content mass ratio of the component (A) to the component (B), (A/B), in the internal olefin sulfonate mixture is from 75/25 to 90/10.

8. The cleansing composition according to claim 1 , wherein a content mass ratio of the component (A) to the component (B), (A/B), in the internal olefin sulfonate mixture is from 10/90 to 30/70.

9. The cleansing composition according to claim 1 , wherein a total content of (A) the internal olefin sulfonate having 12 carbon atoms and (B) the internal olefin sulfonate having 14 carbon atoms is from 0.1 to 80% by mass.

10. The cleansing composition according to claim 1 , comprising one or more selected form the group consisting of an alkyl sulfate and an alkyl polyoxyalkylene sulfate.

11. A method for enhancing foamability and foam dissipation property of a cleansing composition comprising:
mixing with the cleansing composition an internal olefin sulfonate composition comprising (A) an internal olefin sulfonate having 12 carbon atoms and (B) an internal olefin sulfonate having 14 carbon atoms, wherein a content mass ratio of the component (A) to the component (B), (A/B), is from 10/90 to 90/10,
