Description

Hair cleansing composition Technical Field The present invention relates to a hair cleansing composition. Background Internal olefin sulfonates having various carbon numbers have been known and used in various detergent compositions since they can provide excellent effects as anionic surfactants. For example, patent document 1 discloses an aqueous hair cleansing agent containing a sulfonate of an internal olefin, a specific solvent and an organic carboxylic acid and having a specific pH range, which attempts to produce a cleansing agent which can contain other various surfactants and which gives excellent properties in terms of foamability, rinsing property, hair luster after drying, and the like. Patent document 2 discloses a skin or hair cleansing composition containing an internal olefin sulfonate having 12 to 24 carbon atoms and a cationic polymer or an amphoteric polymer. Further, patent document 3 discloses a detergent composition containing the internal olefin sulfonate and a specific anionic surfactant having no sulfuric acid group. These compositions are also intended to be used with other various surfactants, to improve foam retention, rinsing properties, and the like, and to improve the feel and the like when applied to hair or skin. (Patent document 1) Japanese patent application laid-open No. 2014-76983 (Patent document 2) Japanese patent application laid-open No. 2015-27975 (Patent document 3) Japanese patent application laid-open No. 2015-27976 Disclosure of Invention The present invention provides a hair cleansing composition comprising the following components (A) and (B): (A) Sulfonating a raw material olefin having 16 carbon atoms and having an average double bond position of 3.9 to 4.5, to obtain an internal olefin sulfonic acid having 16 carbon atoms or a salt thereof, (B) Anionic surfactants other than component (A), The mass ratio (A)/(B) of the content of the component (A) to the content of the component (B) is 0.01 to 100. In addition, although the internal olefin sulfonate can impart various excellent properties to the composition as described above, as the carbon chain length thereof increases, the hydrophobicity increases and the melting point increases, so that precipitation is likely to occur, resulting in a tendency of lowering the low-temperature stability of the composition. However, none of the above patent documents has made any study on imparting good low-temperature stability, and there is room for improvement. Accordingly, the present inventors have made various studies and as a result have found that a hair cleansing composition exhibiting excellent shampoo performance and excellent low-temperature stability can be obtained by containing a specific internal olefin sulfonic acid or a salt thereof obtained by sulfonating a starting olefin having an average double bond position within a very limited range, and an anionic surfactant other than the internal olefin sulfonic acid or the salt thereof, in a specific mass ratio. That is, the present invention relates to a hair detergent composition using a specific internal olefin sulfonic acid or a salt thereof, which improves the performance when applied to hair, and has excellent low-temperature stability. The hair cleansing composition of the present invention gives good foamability and smooth foam quality when applied to hair, and gives a feeling of softness to hair when rinsed, and is excellent in low-temperature stability and high in usefulness. The term "good foamability" when the hair cleansing composition of the present invention is used to clean hair means a foamability that foams rapidly during hair washing and a sufficient amount of foam required for a reliable feeling of a dirt removing effect. The term "smooth foam" when the hair cleansing composition of the present invention is used to clean hair means a foam which is foamed, fresh and soft, and which can reliably feel the protective effect from the root to the tip of the hair. Further, the term "softness of hair" when the hair is rinsed after the hair is rinsed with the hair cleansing composition of the present invention means that not only the hair is surely soft and elastic in its entirety but also each hair is surely soft and healthy in the hair rinsing. Hereinafter, these effects such as "good foamability", "smooth foam", and "imparting hair softness" when the hair cleansing composition of the present invention is applied to hair are collectively referred to as "shampoo effect". Detailed Description The present invention will be described in detail below. The hair cleansing composition of the present invention contains, as component (a), an internal olefin sulfonic acid having 16 carbon atoms or a salt thereof obtained by sulfonating a starting olefin having 16 carbon atoms, the starting olefin having an average double bond position of 3.9 to 4.5. That is, the internal olefin sulfonic acid having 16 carbon atoms or a salt thereof of the component (a) is a co
