Abstract
A hair cleansing composition including the following components (A) and (B): (A) an internal olefin sulfonic acid having 16 carbon atoms or a salt thereof, obtained by sulfonation of a raw material olefin having 16 carbon atoms and having an average double bond position of 3.9-position or more and 4.5-position or less, and (B) a cationic polymer. A mass ratio of a content of the component (A) to a content of the component (B), (A)/(B), is 1 or more and 500 or less.

A hair cleansing composition comprising following components (A) and (B):
- (A) an internal olefin sulfonic acid having 16 carbon atoms or a salt thereof, obtained by sulfonation of a raw material olefin having 16 carbon atoms and having an average double bond position of 4.0-position to 4.4-position;
- and
- (B) cationated hydroxyethyl cellulose, wherein
- a mass ratio of a content of the component (A) to a content of the component (B), (A)/(B), is 12 or more and 80 or less, and
- in the raw material olefin having 16 carbon atoms,
- a content of a raw material olefin having a double bond position at a 1-positon is less than 5.0 mass %;
- a content of a raw material olefin having a double bond position at a 2-positon is from 20 to 24 mass %;
- and
- a content of a raw material olefin having a double bond position at a 7-position or 8-position is from 12 to 16 mass %, each based on a total mass of the raw material olefin.
