DETAILED DESCRIPTION OF THE INVENTION

[0008] The laundry article for textiles of the present invention comprises a combination of a detergent composition filled in a container and a fragrance composition filled in a container separate from the container in which the detergent composition is filled. The laundry article for textiles of the present invention is not limited to those consisting only of a combination of a detergent composition and a fragrance composition, and may contain other components as appropriate. In the laundry article for textile products of the present invention, the detergent composition contains (A) a surfactant, and the fragrance composition contains (a) a fragrance component and (b) a nonionic surfactant.

[0009] Cleaning composition [Component (A)] In the detergent composition, component (A) is a surfactant that exerts cleaning power on textile products. Examples of the component (A) include nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, etc. The component (A) may be a single component or a mixture of multiple components. As component (A), from the viewpoint of enhancing detergency, one or more surfactants selected from nonionic surfactants and anionic surfactants are preferred. As nonionic surfactants, from the viewpoint of appearance stability after mixing of the detergent composition with the fragrance composition and the effect of suppressing uneven fragrance, polyoxyalkylene-type nonionic surfactants are preferred. Furthermore, from the viewpoint of preventing redeposition, it is more preferred to use them in combination with an anionic surfactant. As anionic surfactants, at least one surfactant selected from the group consisting of polyoxyalkylene alkyl ether sulfates or salts thereof, and linear alkylbenzene sulfonic acids or salts thereof is more preferred.

[0010] <Nonionic surfactant> As the nonionic surfactant in component (A), any nonionic surfactant that has been conventionally used in detergent compositions for textile products and the like can be used. Examples of such nonionic surfactants include polyoxyalkylene-type nonionic surfactants, alkylene oxide adducts of alkylphenols, alkylene oxide adducts of higher amines (amines having an alkyl group having 8 to 22 carbon atoms), polyoxyethylene polyoxypropylene block copolymers, fatty acid alkanolamines, fatty acid alkanolamides, polyhydric alcohol fatty acid esters or alkylene oxide adducts thereof, polyhydric alcohol fatty acid ethers, alkyl (or alkenyl) amine oxides, alkylene oxide adducts of hydrogenated castor oil, sugar fatty acid esters, N-alkyl polyhydroxy fatty acid amides, and alkyl glycosides. The nonionic surfactants may be used alone or in combination of two or more.

[0011] Among the above-mentioned nonionic surfactants for component (A), polyoxyalkylene-type nonionic surfactants are preferred from the viewpoints of appearance stability after mixing of the cleanser composition with the fragrance composition and the effect of suppressing uneven fragrance. Examples of polyoxyalkylene-type nonionic surfactants include a compound represented by the following general formula (A1) (hereinafter, sometimes referred to as "compound (A1)") and a compound represented by the following general formula (A2) (hereinafter, sometimes referred to as "compound (A2)"). The compound (A1) is a fatty acid alkyl(alkenyl) ester. The compound (A2) is an alcohol-type nonionic surfactant.

[0012] In general formula (A1), R 11 is a hydrocarbon group having 7 to 22 carbon atoms, and R 12 represents an alkyl group having 1 to 6 carbon atoms or an alkenyl group having 2 to 6 carbon atoms, EO represents an oxyethylene group, PO represents an oxypropylene group, s represents the average number of repeats of EO and is a number from 3 to 20, t represents the average number of repeats of PO and is a number from 0 to 6, and u represents the average number of repeats of EO and is a number from 0 to 20. When t is 1 or more, [(EO) s / (PO) t In the above formula, the oxyethylene group and the oxypropylene group may be randomly polymerized or block polymerized. The average number of repetitions can be measured by gas chromatography or the like.

[0013] In general formula (A2), R 13is a hydrocarbon group having 7 to 22 carbon atoms, EO represents an oxyethylene group, PO represents an oxypropylene group, v represents the average number of repeats of EO and is a number from 3 to 20, w represents the average number of repeats of PO and is a number from 0 to 6, and x represents the average number of repeats of EO and is a number from 0 to 20. When w is 1 or more, [(EO) v / (PO) w In the above formula, the oxyethylene group and the oxypropylene group may be randomly polymerized or block polymerized. The average number of repetitions can be measured by gas chromatography or the like.

[0014] In general formula (A1), R 11 The hydrocarbon group preferably has 8 to 22 carbon atoms, more preferably 9 to 21 carbon atoms, more preferably 10 to 21 carbon atoms, and even more preferably 11 to 18 carbon atoms. 11 The hydrocarbon group may be a straight chain or a branched chain, and may or may not have an unsaturated bond.

R 12 The alkenyl group in has 2 to 6 carbon atoms, preferably 2 to 3 carbon atoms. s+u is preferably 3 to 20, more preferably 5 to 18. When s+u is equal to or greater than the lower limit, deterioration of the raw material odor of the nonionic surfactant itself is easily suppressed. When s+u is equal to or less than the upper limit, the HLB value can be suppressed, and the application and cleansing properties against sebum stains are easily improved. The HLB value indicates the degree of affinity of a surfactant for water and oil. The HLB value ranges from 0 to 20, with the closer to 0 the higher the lipophilicity and the closer to 20 the higher the hydrophilicity. t is a number of 0 to 6, and preferably 0 to 3.

[0016] The mole number distribution of ethylene oxide or propylene oxide added is not particularly limited. The distribution of the number of moles of ethylene oxide or propylene oxide added tends to vary depending on the reaction method used to produce the nonionic surfactant. For example, when ethylene oxide or propylene oxide is added to a hydrophobic raw material using a common alkali catalyst such as sodium hydroxide or potassium hydroxide, the distribution of the number of moles of ethylene oxide or propylene oxide added tends to be relatively wide. 3+ , Ga 3+ , In 3+ , Tl 3+ , Co 3+ ,Sc. 3+ , La 3+ , Mn 2+ When ethylene oxide or propylene oxide is added to a hydrophobic raw material using a specific alkoxylation catalyst such as magnesium oxide to which a metal ion such as ethylene oxide or propylene oxide has been added, the mole number distribution of the ethylene oxide or propylene oxide added tends to be a relatively narrow distribution.

[0017] In the polyoxyethylene fatty acid alkyl ester, the narrow ratio, which indicates the distribution of compounds with different numbers of moles of ethylene oxide added (addition mole distribution), is preferably 20% by mass or more. The upper limit of the narrow ratio is preferably substantially 80% by mass or less. The narrow ratio is more preferably 20 to 60% by mass. The higher the narrow ratio, the better the detergency can be obtained, but if it is too high, there is a risk of reduced storage stability at low temperatures, so the narrow ratio is more preferably 25 to 40% by mass. The narrow ratio of a polyoxyalkylene type nonionic surfactant such as a polyoxyethylene fatty acid alkyl ester is a value calculated by the following mathematical formula (S).

After the addition of ethylene oxide was completed, the mixture was aged for 30 minutes at a temperature of 180°C and a pressure of 0.3 MPa or less, and then unreacted ethylene oxide was distilled off for 10 minutes at a temperature of 180°C and a pressure of 6.0 kPa or less. Next, after cooling to a temperature of 100° C. or less, the reaction product was neutralized by adding 70% by mass of p-toluenesulfonic acid so that the pH of a 1% by mass aqueous solution of the reaction product became approximately 7, thereby obtaining Component A-2. A-3: Linear alkylbenzene sulfonate having an alkyl group having 10 to 14 carbon atoms (manufactured by Lion Corporation, trade name "Lipon (registered trademark) LH-200") A-4: Polyoxyethylene alkyl ether sulfate (in compound (A3), R 14 is an alkyl group having 12 carbon atoms and an alkyl group having 14 carbon atoms, p is 1, q is 0, M + is a sodium ion) Component A-4 was synthesized by the following method. A 4-L autoclave was charged with 400 g of P&G's CO1270 alcohol (a mixture of a 75 / 25 mass ratio of a 12-carbon alcohol and a 14-carbon alcohol) as the raw material alcohol and 0.8 g of potassium hydroxide as the reaction catalyst. The autoclave was then purged with nitrogen and heated with stirring. Subsequently, 91 g of ethylene oxide was introduced and reacted while maintaining the temperature at 180°C and the pressure at 0.3 MPa or less to obtain an alcohol ethoxylate. Next, 237 g of the alcohol ethoxylate obtained above was placed in a 500 mL flask equipped with a stirrer. After purging with nitrogen, 96 g of liquid sulfuric anhydride (sulfan) was slowly added dropwise while maintaining the reaction temperature at 40°C. After the dropwise addition, stirring was continued for 1 hour (sulfation reaction), and polyoxyethylene alkyl ether sulfate was obtained. This was then neutralized with aqueous sodium hydroxide to obtain component A-4.
