A specific alkoxylation catalyst such as magnesium oxide to which metal ions such as Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ , Mn ^{2+ and the} like described in JP-B-615038 is added. When ethylene oxide or propylene oxide is added to the raw material, the distribution of v or w becomes relatively narrow.

As the component (a1-1), a compound represented by the formula (A1) is more preferable, and a compound in which t in the formula (A1) is 0 (that is, a polyoxyethylene fatty acid alkyl ester) is more preferable. Polyoxyethylene fatty acid methyl ester (hereinafter referred to as “MEE”) in which R ^{12 in} A1) is a methyl group is particularly preferred from the viewpoint of improvement in detergency and solubility of a liquid detergent for clothing.

By using a polyoxyethylene fatty acid alkyl ester as the component (a1-1), it is excellent in solubility in water and a high detergency can be obtained more easily. In addition, when the components (a1) and (a2) are used in the form of a liquid cleaning agent, the viscosity does not significantly increase (gelation) even if the concentration of the component (a1) in the cleaning agent is high, and good. Therefore, it is possible to obtain a concentrated type cleaning agent that is excellent in liquid stability having excellent fluidity.
Polyoxyethylene fatty acid alkyl ester (especially MEE) is a nonionic surfactant in which the orientation of molecules in an aqueous solution system is weak and the micelle is unstable, so it does not cause gelation or the like in a high concentration region. A large amount can be blended in the detergent alone. Moreover, the solubility to water is favorable. Furthermore, it has good fluidity even at high concentrations. Therefore, the polyoxyethylene fatty acid alkyl ester becomes uniform quickly in the cleaning liquid after being poured into the water in the washing tub. Thereby, when polyoxyethylene fatty acid alkyl ester is used, since it can contact textile products at a predetermined concentration from the initial stage of cleaning, high cleaning power can be obtained.
In addition, the polyoxyethylene fatty acid alkyl ester is preferably such that the content of the ethylene oxide adduct having an EO addition mole number of 2 or less is 0.5% by mass or less based on the entire polyoxyethylene fatty acid alkyl ester. More preferred is 0.2% by mass or less. When the total content is 0.5% by mass or less, a detergent having a lower raw material odor derived from the polyoxyethylene fatty acid alkyl ester is easily obtained.

The compound represented by the formula (A1) and the compound represented by the formula (A2) preferably have a narrow ratio of 20% by mass or more, and more preferably 30% by mass or more. The higher the narrow rate, the better the cleaning power. In addition, when the narrow ratio is 20% by mass or more, particularly 30% by mass or more, a detergent with less raw material odor of the surfactant is easily obtained.
When the compound represented by the formula (A1) is produced by a conventional method, the product, together with the compound represented by the formula (A1), is represented by a component that does not contribute to detergency, for example, the formula (A1). The fatty acid ester which is a raw material of the compound and the ethylene oxide adduct having s of 1 or 2 in the compound represented by the formula (A1) coexist to reduce the narrow rate. For this reason, if the narrow ratio is high, the coexisting components are sufficiently small, and the problem of reduced cleaning power and raw material odor hardly occurs. The same applies to the compound represented by the formula (A2).
Although it does not specifically limit as an upper limit of the said narrow rate, It is preferable that it is 80 mass% or less substantially.
Since the liquid stability and solubility are improved, the narrow ratio is more preferably 20 to 50% by mass, and further preferably 25 to 45% by mass.
Here, in this specification, the “narrow ratio” indicates a distribution ratio of ethylene oxide adducts having different EO addition mole numbers, and is represented by the following formula (S).

In the formula (S), p _max represents the number of moles of EO added to the ethylene oxide adduct most present in the entire ethylene oxide adduct. i represents the number of moles of EO added. Yi represents the ratio (% by mass) of the ethylene oxide adduct present in the entire ethylene oxide adduct, where the number of moles of EO added is i.

The narrow rate can be controlled by, for example, a method for producing a compound represented by the formula (A1) or a compound represented by the formula (A2). The method for producing the compound represented by the formula (A1) is not particularly limited. For example, ethylene oxide and / or propylene oxide is added to the fatty acid alkyl ester using a surface-modified composite metal oxide catalyst. It can be easily produced by a polymerization method (see JP-A No. 2000-144179). As a method for producing the compound represented by the formula (A2), for example, by using a surface-modified composite metal oxide catalyst, an addition polymerization of ethylene oxide and / or propylene oxide to an alcohol having 6 to 22 carbon atoms is performed. Can be manufactured.
Specific examples of suitable surface-modified composite metal oxide catalysts used in such a method include metal ions (Al ³⁺ , Ga ³⁺ , In ³⁺ , Tl ³⁺ , Co ³⁺ , Sc ³⁺ , La ³⁺ , Mn ^2+, etc.) are added to the composite metal oxide catalyst such as magnesium oxide and the hydrotalcite surface-modified with metal hydroxide and / or metal alkoxide. A calcined product catalyst is mentioned.
In the surface modification using the composite metal oxide catalyst, it is preferable to use a composite metal oxide in combination with a metal hydroxide and / or a metal alkoxide. In this case, the ratio of the metal hydroxide and / or metal alkoxide is preferably 0.5 to 10 parts by mass and more preferably 1 to 5 parts by mass with respect to 100 parts by mass of the composite metal oxide. .

  As another method for producing the compound represented by the formula (A1), there is a method of adding an alkylene oxide to a fatty acid alkyl ester with an alkoxylation catalyst prepared from a mixture of an alkaline earth metal compound and oxyacid. is there. The above alkoxylation catalyst is disclosed in Japanese Patent No. 4777609, International Publication No. 1993/004030, International Publication No. 2002/038269, International Publication No. 2012/028435, and the like. For example, alkaline earth of carboxylic acid Examples thereof include alkoxylation catalysts prepared from a mixture of a metal salt and / or an alkaline earth metal salt of hydroxycarboxylic acid and sulfuric acid.

If the content of the component (a1-1) in the component (a1) is not less than the above lower limit value, the sebum detergency is more likely to be improved, and if it is not more than the above upper limit value, rinsing properties and liquid stability of the cleaning agent are improved. Becomes easier to improve.

  Moreover, 30-270 mass ppm is preferable with respect to the total mass of a cleaning liquid, content of the (a1-1) component in a cleaning liquid is more preferable, 50-250 mass ppm is more preferable, and its 65-200 mass ppm is more preferable.

In addition, the (a1) component and (a2) component which were used at the process (1) may be carried in in rinse water. This is considered because the (a1) component and the (a2) component adhering to the textiles washed in the step (1) are eluted in the rinse water.
The content of the component (b1) in the rinse water is preferably larger than the content of the component (a1-2). When there are many (a1-2) components in rinse water, adsorption | suction to the textiles of (b1) component may be prevented by the (a1-2) component. If the content of the component (b1) in the rinse water is larger than the content of the component (a1-2), the adsorption of the component (b1) to the fiber product is hardly hindered, and higher flexibility is obtained.

  When the component (b1) is used as a softening agent, the content of the component (b1) is preferably 1 to 50% by weight, more preferably 3 to 35% by weight, based on the total weight of the softening agent. 25 mass% is further more preferable.

<(B2) component>
The component (b2) is a cyclic dextrin.
By using the component (b2) in the step (2), the recontamination prevention performance is further increased.

  The component (b2) may be a dextrin having one or more cyclic structures in the molecule, and examples thereof include cyclodextrin and highly branched cyclic dextrin. Of these, highly branched cyclic dextrin is preferred.

  Examples of the cyclodextrin include α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin and the like. These cyclodextrins have a large internal volume per molecular weight in the order of γ, β, α. The larger the internal volume per molecular weight, the higher the ability to capture, so it is easier to capture dirt, and it is thought that the cleaning power and deodorizing effect can be enhanced. Accordingly, β-cyclodextrin and γ-cyclodextrin are preferable as the cyclodextrin. Β-cyclodextrin is preferable in that it can be obtained at low cost and the production cost of the liquid detergent can be suppressed.

  As α-cyclodextrin, Celdex A-100 (trade name, manufactured by Nippon Food Chemical Co., Ltd.) and the like, as β-cyclodextrin, Celldex B-100 (trade name, manufactured by Nippon Food Chemical Co., Ltd.), etc. Examples of γ-cyclodextrin include CAVAMAX (R) W8 Food (trade name, manufactured by Cyclochem).

A highly branched cyclic dextrin is a glucan having an inner branched cyclic structure portion and an outer branched structure portion. The inner branched cyclic structure portion is a cyclic glucan chain formed by an α-1,4-glucoside bond and an α-1,6-glucoside bond, and the outer branched structure portion is bonded to the inner branched cyclic structure portion. It is composed of acyclic glucan chains. Such highly branched cyclic dextrins are also called cluster dextrins.
The highly branched cyclic dextrin mainly includes one having an inner branched cyclic structure portion in the molecule and a weight average polymerization degree of about 2500 in which a large number of acyclic glucan chains are bonded to the inner branched cyclic structure portion.

The degree of polymerization of the highly branched cyclic dextrin is preferably 50 to 10,000, and more preferably 50 to 5,000.
The molecular weight of the highly branched cyclic dextrin is preferably 30,000 to 1,000,000, for example.
The degree of polymerization of the inner branched cyclic structure portion of the highly branched cyclic dextrin is preferably 10 to 100, for example.
For example, the degree of polymerization of the outer branched structure portion of the highly branched cyclic dextrin is preferably 40 or more.
For example, the average degree of polymerization of each glucan chain constituting the outer branched structure portion of the highly branched cyclic dextrin is preferably 10 to 20.

A highly branched cyclic dextrin is produced, for example, by using starch as a raw material and acting on an enzyme called a branching enzyme.
Starch, which is a raw material, is composed of amylose in which glucose is linearly bound by α-1,4-glucoside bonds and amylopectin having a structure branched by α-1,6-glucoside bonds. Amylopectin is a macromolecule in which many cluster structures are linked.
A branching enzyme is a glucan chain transferase widely distributed in animals, plants, and microorganisms, and acts on the seam portion of the cluster structure of amylopectin to catalyze the reaction of cyclizing it.
Examples of the highly branched cyclic dextrin include a glucan having an inner branched cyclic structure portion and an outer branched structure portion described in JP-A-8-134104 and having a polymerization degree in the range of 50 to 10,000. The highly branched cyclic dextrin has a specific structure as described above and has a high degree of polymerization (molecular weight), α-cyclodextrin (glucose unit = 6), β-cyclodextrin (glucose unit = 7), It differs from general cyclodextrins in which 6 to 8 glucoses are bound, such as γ-cyclodextrin (glucose unit = 8).
