Claim:
1. A cleansing composition for skin or hair comprising an internal olefin sulfonate (A) having 12 or more and 24 or less carbon atoms, wherein a total content of an internal olefin sulfonate having 16 carbon atoms and an internal olefin sulfonate having 18 carbon atoms in the internal olefin sulfonate (A) is 50% by mass or more; a mass content ratio of the internal olefin sulfonate having 16 carbon atoms to the internal olefin sulfonate having 18 carbon atoms in the internal olefin sulfonate (A) (internal olefin sulfonate having 16 carbon atoms/internal olefin sulfonate having 18 carbon atoms) is from 75/25 to 99/1; a content of an internal olefin sulfonate in which a sulfonate group is present at the C-2 position in the internal olefin sulfonate (A) is 25% by mass or less; and a mass content ratio of a hydroxy form of the internal olefin sulfonate to an olefin form of the internal olefin sulfonate in the internal olefin sulfonate (A) (hydroxy form/olefin form) is from 50/50 to 100/0.
