(IO-2S) is preferably an internal olefin sulfonate having 17 to 24 carbon atoms in which the sulfonic acid group is present at the 5th to 9th positions.

In addition, the mass ratio (IO-1) / (IO-2) of the internal olefins for obtaining the component (A) may be based on the finally obtained component (A). For example, even if the internal olefin sulfonate obtained by mixing internal olefin sulfonates obtained using olefins with a mass ratio (IO-1) / (IO-2) outside the above range as raw materials, when the mass ratio (IO-1) / (IO-2) is within the above range in the composition of the olefins corresponding to the raw material olefins, it can be regarded as corresponding to the internal olefin sulfonate of the component (A) obtained using a predetermined olefin as the raw material.

The internal olefin as the raw material of the component (A) includes those containing a trace amount of so-called alpha-olefin (hereinafter also referred to as α-olefin) in which the position of the double bond is at the 1st position of the carbon chain.

When internal olefins are sulfonated, β-sultones are quantitatively produced. A part of the β-sultones is converted into γ-sultones and olefin sulfonic acids, and these are further converted into hydroxyalkane sulfonates and olefin sulfonates in the neutralization and hydrolysis steps (for example, J. Am. Oil Chem. Soc. 69, 39 (1992)). Here, the hydroxy group of the obtained hydroxyalkane sulfonate is inside the alkane chain, and the double bond of the olefin sulfonate is inside the olefin chain. Also, the obtained product is mainly a mixture of these, and a small amount of the product may contain a hydroxyalkane sulfonate having a hydroxy group at the end of the carbon chain or an olefin sulfonate having a double bond at the end of the carbon chain. In this specification, each of these products and their mixtures are collectively referred to as internal olefin sulfonates ((A) component). Further, hydroxyalkane sulfonates are referred to as hydroxy forms (HAS) of internal olefin sulfonates, and olefin sulfonates are referred to as olefin forms of internal olefin sulfonates (hereinafter also referred to as IOS). The mass ratio of the compounds in the (A) component can be measured by HPLC-MS. Specifically, the mass ratio can be determined from the HPLC-MS peak area of the (A) component. The distribution of double bonds in the raw material internal olefins can be measured, for example, by a gas chromatograph mass spectrometer (hereinafter abbreviated as GC-MS). Specifically, each component having a different carbon chain length and double bond position is accurately separated by a gas chromatograph analyzer (hereinafter abbreviated as GC), and each is subjected to a mass spectrometer (hereinafter abbreviated as MS) to identify the double bond position, and the ratio of each can be determined from the GC peak area. The content of the olefin having a double bond at the specific position shall be determined using the value obtained from the GC peak area. Also, when olefins having different carbon numbers are mixed and used, the position distribution of the double bonds shall be represented by the position distribution of the double bonds in olefins having the same carbon number. In addition, in this specification, when a plurality of internal olefin sulfonates obtained from a plurality of raw material olefins having different double bond positions are mixed and used, the double bond position distribution of the olefins serving as raw materials for the internal olefin sulfonates shall be calculated for olefins having the same carbon number. <(B) component> The (B) component is an organic solvent having a hydroxyl group and is generally used as a solvent.

Examples [Preparation of Component (A)] (1) Synthesis of internal olefins A - C (Production Examples A - C) Internal olefins A - C, which are raw materials for component (A) and component (A') (comparative component of component A), were synthesized as follows. Into a flask equipped with a stirrer, 7000 g (25.9 mol) of 1 - octadecanol (product name: Calcol 8098, manufactured by Kao Corporation) and 700 g (10% by mass based on the raw material alcohol) of γ - alumina (manufactured by STREM Chemicals, Inc.) as a solid acid catalyst were charged. While stirring, nitrogen (7000 mL / min.) was passed through the system at 280 °C, and the reaction time was changed for each of Production Examples A - C to carry out the reaction. The obtained crude internal olefin was transferred to a distillation flask and distilled at 148 - 158 °C / 0.5 mmHg to obtain internal olefins A - C having 18 carbon atoms with an olefin purity of 100%. The double - bond distribution of the obtained internal olefins is shown in Table 1. (2) Internal olefin D having 16 carbon atoms As the internal olefin D having 16 carbon atoms, the internal olefin obtained by the method described in Production Example C of JP - A - 2014 - 76988 was used. The double - bond distribution of internal olefin D is shown in Table 1. The double - bond distribution of the internal olefin was measured by gas chromatography (hereinafter abbreviated as GC). Specifically, after reacting dimethyldisulfide with the internal olefin to form a dithiolated derivative, each component was separated by GC. As a result, the double - bond distribution of the internal olefin was determined from the respective peak areas. In the case of olefins having 18 carbon atoms, the internal olefin having a double bond at the 8th position and the internal olefin having a double bond at the 9th position cannot be structurally distinguished, but they can be distinguished when sulfonated. Therefore, for convenience, the value obtained by dividing the amount of the internal olefin having a double bond at the 8th position by 2 was shown in each column of the 8th and 9th positions. Similarly, in the case of olefins having 16 carbon atoms, for convenience, the value obtained by dividing the amount of the internal olefin having a double bond at the 7th position by 2 was shown in each column of the 7th and 8th positions. The apparatus and analysis conditions used for the measurement are as follows. GC apparatus "HP6890" (manufactured by HEWLETT PACKARD), column "Ultra-Alloy-1HT capillary column" (30 m × 250 μm × 0.15 μm, manufactured by Frontier Lab Co., Ltd.), detector (hydrogen flame ionization detector (FID)), injection temperature 300 °C, detector temperature 350 °C, He flow rate 4.6 mL / min (3) Synthesis of (a-1), (a-4), (a-1'), and (a'-2) Internal olefins A to D were sulfonated using a thin-film sulfonation reactor with an external jacket by passing sulfur trioxide gas and cooling water at 20 °C through the external jacket of the reactor. The molar ratio of SO ３ / internal olefin was set to 1.09. The obtained sulfonated product was added to an aqueous alkali solution prepared with 1.5 molar equivalents of sodium hydroxide relative to the theoretical acid value, and neutralized at 30 °C for 1 hour while stirring. The neutralized product was hydrolyzed by heating in an autoclave at 160 °C for 1 hour to obtain crude products of sodium internal olefin sulfonates. 300 g of the crude product was transferred to a separatory funnel, 300 mL of ethanol was added, and then 300 mL of petroleum ether was added each time to extract and remove oil-soluble impurities. At this time, the inorganic compound (main component is mirabilite) precipitated at the oil-water interface due to the addition of ethanol was also separated and removed from the aqueous phase by the oil-water separation operation. This extraction and removal operation was performed 3 times. By evaporating the aqueous phase to dryness, the following sodium internal olefin sulfonates were obtained. Here, the sodium internal olefin sulfonate obtained using internal olefin A as a raw material was designated as (a-1), the sodium internal olefin sulfonate obtained using internal olefin B as a raw material was designated as (a-4), the sodium internal olefin sulfonate obtained using internal olefin C as a raw material was designated as (a'-1), and the sodium internal olefin sulfonate obtained using internal olefin D as a raw material was designated as (a'-2). The content ratio of the internal olefin sulfonate bonded with a sulfonic acid group was measured by high performance liquid chromatography / mass spectrometer (HPLC-MS). Specifically, the hydroxy form bonded with a sulfonic acid group was separated by high performance liquid chromatography (HPLC), and each was identified by applying to a mass spectrometer (MS).

The results are shown in Tables 5 to 7. Specifically, the liquid detergent compositions for textile products shown in Tables 5 to 7 were prepared as follows. A Teflon (registered trademark) stirrer piece with a length of 5 cm was put into a 200 mL glass beaker and its mass was measured. Next, 80 g of ion-exchanged water at 20 °C, component (A) or component (A'), and component (B) were put in, and the upper surface of the beaker was sealed with Saran Wrap (registered trademark). The beaker containing the contents was placed in a 60 °C water bath installed on a magnetic stirrer, and stirred at 100 r / min for 30 minutes within the temperature range of 60 ± 2 °C of the water in the water bath. Next, the water in the water bath was replaced with tap water at 5 °C, and the composition in the beaker was cooled until its temperature reached 20 °C. Next, the Saran Wrap (registered trademark) was removed, ion-exchanged water was added so that the mass of the contents became 100 g, and it was stirred again at 100 r / min for 30 seconds to obtain the liquid detergent compositions for textile products described in Tables 5 to 7. <Evaluation Method for Softness> (1) Pretreatment of the textile products for evaluation In advance, 1.7 kg of cotton jersey ((manufactured by Shikisensha Co., Ltd.), cotton knit un-sil (not silk processed), 100% cotton) was washed twice cumulatively in a fully automatic washing machine (NA-F702P manufactured by National) using the standard course (when washing, 4.7 g of Emulgen 108 (manufactured by Kao Corporation), 47 L of water, washing for 9 minutes, rinsing twice, and dehydrating for 3 minutes), and then washed three times cumulatively with only water (47 L of water, washing for 9 minutes, rinsing twice, and dehydrating for 3 minutes), and dried for 24 hours in an environment of 23°C and 45% RH. (2) Washing of the evaluation fiber product (2-1) Method (1) 6.0 L of tap water (3.5°dH) adjusted to 5°C was poured into an electric bucket-type washing machine (model number "N-BK2" manufactured by National). Then, 4 pieces (about 140 g) of the cotton jersey pretreated by the above method were put in. Next, the liquid detergent composition for fiber products described in Tables 5 and 6 was put in so that the concentration of component (A) in the bath was 200 mg / kg, and it was washed for 10 minutes. After washing, dehydration was carried out for 1 minute using a two-layer washing machine (model number "PS-H35L" manufactured by Hitachi). Next, 6.0 L of the above 5°C tap water was poured into the above bucket washing machine, and a cotton towel after dehydration by the two-layer washing machine was put in and rinsed for 3 minutes. Then, after carrying out the same dehydration treatment for 1 minute using the two-layer washing machine, it was left to dry for 12 hours under the conditions of 20°C and 43% RH. (2-2) Method (2) 6.0 L of tap water (3.5°dH) adjusted to 5°C was poured into an electric bucket-type washing machine (model number "N-BK2" manufactured by National). Also, the liquid detergent composition for fiber products described in Table 7 was sprinkled and adhered to 4 pieces (about 140 g) of the cotton jersey pretreated by the above method so that the concentration of component (A) in the bath was 200 mg / kg. The cotton jersey to which the liquid detergent composition for fiber products described in Table 7 adhered was put into the above washing machine and washed for 10 minutes. After washing, dehydration was carried out for 1 minute using a two-layer washing machine (model number "PS-H35L" manufactured by Hitachi). Next, 6.0 L of the above 5°C tap water was poured into the above bucket washing machine, and a cotton towel after dehydration by the two-layer washing machine was put in and rinsed for 3 minutes. Then, after carrying out the same dehydration treatment for 1 minute using the two-layer washing machine, it was left to dry for 12 hours under the conditions of 20°C and 43% RH. (3)Flexibility evaluation The flexibility of the cotton knitted fabric after drying was scored by six experts in the evaluation of fabric texture according to the following criteria, and the average score of the six was calculated to three significant figures by rounding. In scoring, for example, if it was evaluated to be between score 2 and score 3, it was scored as 2.5. -1... It does not finish softer than the cotton knitted fabric treated with the composition of Comparative Example 1. 0... It finished with the same softness as the cotton knitted fabric treated with the composition of Standard 1. 1... It finished slightly softer compared to the cotton knitted fabric treated with the composition of Standard 1. 2... It finished softer compared to the cotton knitted fabric treated with the composition of Standard 1. 3... It finished as soft as the cotton knitted fabric treated with the composition of Standard 2. For Table 5, the composition of Comparative Example 3 was used as Standard 1 and the composition of Example 1 was used as Standard 2 for evaluation. For Table 6, the composition of Comparative Example 3 was used as Standard 1 and the composition of Example 8 was used as Standard 2 for evaluation. For Table 7, the composition of Comparative Example 3 was used as Standard 1 and the composition of Example 15 was used as Standard 2 for evaluation. Furthermore, the obtained average score was normalized to a relative value when 3 points (the score of Standard 2) in the above judgment criteria was set to 10 points. When the normalized value was less than 0 points (Standard 1), it was set to "-1". The results are shown in Tables 5, 6, and 7. <Method for evaluating detergency> (1) Preparation of model sebum artificial contaminated cloth A model sebum artificial contaminated cloth was prepared by attaching a model sebum artificial contamination liquid with the following composition to the cloth. The attachment of the model sebum artificial contamination liquid to the cloth was performed by printing the artificial contamination liquid on the cloth using a gravure roll coater. The process of attaching the model sebum artificial contamination liquid to the cloth to prepare the model sebum artificial contamination liquid was carried out with a cell volume of the gravure roll of 58 cm ３ / m ２ , a coating speed of 1.0 m / min, a drying temperature of 100 °C, and a drying time of 1 min. The cloth used was Cotton 2003 (manufactured by Taniguchi Shoten). * Composition of the model sebum artificial contamination solution: lauric acid 0.4% by mass, myristic acid 3.1% by mass, pentadecanoic acid 2.3% by mass, palmitic acid 6.2% by mass, heptadecanoic acid 0.4% by mass, stearic acid 1.6% by mass, oleic acid 7.8% by mass, triolein 13.0% by mass, palmitic acid n - hexadecyl 2.2% by mass, squalene 6.5% by mass, egg white lecithin liquid crystal 1.9% by mass, Kanuma red clay 8.1% by mass, carbon black 0.01% by mass, balance water (total 100% by mass) (2) Evaluation of detergency Five pieces of the model sebum artificial contaminated cloth (6 cm × 6 cm) prepared above were washed at 85 rpm for 10 minutes using a Tergotometer (Ueshima, MS - 8212). For the washing conditions, in each case, tap water (3.5°dH, 20°C) was injected so that the concentration of the liquid detergent composition for textile products described in Table 5 was 0.033% by mass, and the washing was carried out at a water temperature of 20°C. After washing, it was rinsed with tap water (20°C) for 3 minutes. The washing rate (%) was measured by the following method, and the average value of the five pieces was determined. The results are shown in Table 5. The reflectance of the original cloth before contamination and at 550 nm before and after washing was measured using a color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd., Z - 300A). Washing rate (%) = 100 × [(reflectance after washing - reflectance before washing) / (reflectance of the original cloth - reflectance before washing)] (1) Mass ratio of (IO - 1) / (IO - 2) in the raw material olefin (2) Mass ratio of (IO - 1S) / (IO - 2S) in the internal olefin sulfonate
