Abstract

The internal olefin sulfonate composition comprises (A) an internal olefin sulfonate having 16 carbon atoms and (B) an internal olefin sulfonate having 12 carbon atoms, in which a content mass ratio of the component (A) to the component (B), (A/B), is from 10/90 to 90/10.

First claim

The invention claimed is:

1. An internal olefin sulfonate composition comprising (A) an internal olefin sulfonate having 16 carbon atoms and (B) an internal olefin sulfonate having 12 carbon atoms,
wherein a content mass ratio of the component (A) to the component (B), (A/B), is from 10/90 to 90/10, and
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 16 and 12 carbon atoms is 25% by mass or less.

2. The internal olefin sulfonate composition according to claim 1 , wherein a total content of (A) the internal olefin sulfonate having 16 carbon atoms and (B) the internal olefin sulfonate having 12 carbon atoms in the internal olefin sulfonate composition is from 50 to 100% by mass.

3. The internal olefin sulfonate composition according to claim 1 , wherein a mass ratio of a content of a hydroxy form in the internal olefin sulfonate having 16 and 12 carbon atoms to a content of an olefin form in the internal olefin sulfonate having 16 and 12 carbon atoms, (hydroxy form/olefin form), is from 50/50 to 100/0.

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

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

6. The internal olefin sulfonate composition according to claim 1 , obtained by sulfonating a raw material internal olefin composition 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 45% by mass.

7. The internal olefin sulfonate composition according to claim 1 , wherein a content of the raw material internal olefin in which a double bond is present at a C-2 position in the raw material internal olefin composition is from 15 to 35% by mass.

8. The internal olefin sulfonate 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 composition is from 10/90 to 15/85.

9. The internal olefin sulfonate 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 composition is from 40/60 to 60/40.

10. A cleansing composition obtained by formulating the internal olefin sulfonate composition according to claim 1 .

11. A cleansing composition comprising (A) an internal olefin sulfonate having 16 carbon atoms and (B) an internal olefin sulfonate having 12 carbon atoms, wherein a content mass ratio of the component (A) to the component (B), (A/B), is from 10/90 to 90/10.

12. The cleansing composition according to claim 11 , wherein a total content of (A) the internal olefin sulfonate having 16 carbon atoms and (B) the internal olefin sulfonate having 12 carbon atoms is from 0.1 to 80% by mass.

13. The cleansing composition according to claim 11 , comprising one or more selected from the group consisting of an alkyl sulfate and an alkyl polyoxyalkylene sulfate.

14. The cleansing composition according to claim 11 for dishwashing.

15. The cleansing composition according to claim 11 for laundry detergent.

16. The cleansing composition according to claim 11 for washing hair.

17. The cleansing composition according to claim 11 for washing skin.
