When the content is 5% by mass or more, the detergency is improved. On the other hand, when the content exceeds 40% by mass, the detergency is not significantly increased. .

<(B) component>
Component (B) is a crosslinked carboxyvinyl polymer and an anionic thickener.
By including the component (B) in the liquid detergent composition, viscosity suitable for the liquid detergent composition for clothing can be obtained. Viscosity suitable for clothing means that when a liquid detergent composition is applied directly to a soiled part from a bottle or cap, it exhibits a thixotropy and has good liquid drainage and does not drip. To do. The thixotropy is a property in which the fluidity is low in a stationary state, the fluidity is increased by stirring or shaking, and the fluidity is restored to a low state when stationary.
Component (B) is a polymer having a carboxy group and a cross-linked structure. When the carboxy group is ionized in water due to its molecular structure, it spreads in water like a network due to intramolecular ionic repulsion, and water in the structure. It is considered that thixotropic viscosity is expressed by holding molecules.

Examples of the component (B) preferably used in the present invention include a crosslinked polymer obtained by crosslinking a copolymer of at least one monomer composed of acrylic acid, methacrylic acid or an ester thereof and an alkyl acrylate with a crosslinking agent.
The alkyl chain length of the alkyl acrylate is preferably 8 to 40 carbon atoms, more preferably 10 to 30. When the number of carbon atoms is 8 or more, the polymer easily swells, and when it is 40 or less, good solubility in water is easily obtained. In the alkyl acrylate, specific examples of the alkyl chain include octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl, octadecyl, isooctadecyl, Nonadecyl group, icosyl group, henicosyl group, docosyl group, tricosyl group, tetracosyl group, pentacosyl group, hexacosyl group, heptacosyl group, octacosyl group, nonacosyl group, triacontyl group can be mentioned.

Examples of crosslinked polymers obtained by crosslinking a copolymer of acrylic acid and an alkyl acrylate (alkyl chain having 10 to 30 carbon atoms) with an allyl ether of sucrose or an allyl ether crosslinker of pentaerythritol include Carbopol Ultrez 21 and Carbopol. Ultrez 20, Carbopole EZ4, Carbopole EZ5, Carbopole 1342, Carbopole 1382, Carbopole ETD2020, PemulenTR-1, PemulenTR-2, Carbopole AquaSF-1, Carbopole Ultrez20, Carbopole ETD2020 (all product names, Louvre) Zol).

Alternatively, as the component (B), cross-linked polyacrylic acid in which the main chain is polyacrylic acid and the polyacrylic acid is cross-linked with a cross-linking agent can also be used. Examples of polyacrylic acid include polyacrylic acid described in JP-B-32-4141. Examples of the crosslinking agent include allyl sucrose and pentaerythritol.

The component (B) is an anionic thickener exhibiting anionic property in the liquid, and can form and precipitate an ion complex with the cationic surfactant that is the component (C). If such precipitation occurs, the thickening effect by the component (B) may not be sufficiently obtained, or the appearance of the liquid may become cloudy.
Moreover, since the anionic chelating agent (D) coexists in the liquid, the formation of a network structure by the component (B) may be insufficient due to the shielding effect due to the ionicity. If the formation of the network structure is insufficient, the thickening effect by the component (B) cannot be sufficiently obtained.
The content of the component (B) is preferably 0.05 to 1% by mass and more preferably 0.1 to 0.5% with respect to the total mass of the liquid detergent composition. When the content is 0.05% by mass or more, a sufficient thickening effect is easily obtained even in the presence of the component (C) and the component (D). When the content is 1% by mass or less, the viscosity of the liquid does not become excessively high, and good penetrability into the fiber of the garment is easily obtained.

In the liquid detergent composition of the present invention, the water-soluble crosslinked carboxyvinyl polymer as the component (B) can be used as it is.
Further, a water-soluble crosslinked carboxyvinyl polymer part or a completely neutralized salt may be used. In this case, before preparing a liquid detergent composition, what made the said polymer partial or complete neutralization salt previously can be used. Alternatively, the polymer can be used as a partially or fully neutralized salt during the process of preparing the composition.
When the water-soluble crosslinked carboxyvinyl polymer is used as a partial or completely neutralized salt, a basic compound is used. Examples of the basic compound include monoethanolamine, diethanolamine, triethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1,3-propanediol, isopropanolamine, diethanolamine, Examples include alkanolamines such as isopropanolamine, alkali metal hydroxides such as sodium hydroxide and potassium hydroxide, basic amino acids such as arginine and lysine, and ammonia. Usually, monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, diisopropanolamine and sodium hydroxide are used.
The addition amount of these basic compounds may be an amount sufficient to neutralize the crosslinked carboxyvinyl polymer that is an anionic polymer, and may be appropriately set according to the type and amount of the crosslinked carboxyvinyl polymer. That's fine.

<Other thickeners>
In the cleaning composition of the present invention, other thickeners other than the component (B) may be used in combination as long as a desired effect is obtained. For example, even if a non-crosslinked polymer is blended, the viscosity can be increased. However, these non-crosslinked polymers are poor in thickening efficiency and require a large amount. In that case, even if it is a synthetic polymer or a natural polymer, liquid separation or the like is likely to occur, that is, appearance stability is likely to deteriorate, and the enzyme stability is also adversely affected. Moreover, since the degree of stringiness, which is one of the liquid properties, increases, the liquid breakage becomes worse, causing problems in usability.
The amount of the non-crosslinked polymer used is preferably 0.5% by mass or less, more preferably 0.3% by mass or less, and most preferably zero with respect to the total mass of the cleaning composition. Specifically, 0 to 0.5% by mass is preferable, and 0 to 0.3% by mass is more preferable.

<(C) component>
As the component (C), a known cationic surfactant can be appropriately used in the liquid cleaning composition for clothing. By including the component (C) in the liquid detergent composition, the stability over time of the viscosity is improved. In addition, a sterilizing effect that suppresses the odor of clothes after washing or drying by imparting sterilizing power or antibacterial power to the liquid cleaning composition for clothes is also obtained.
As the component (C), a monovalent cationic surfactant is preferable. In particular, an ammonium salt type cationic surfactant is preferable in terms of blending stability, and a compound represented by the following general formula (2) is more preferable.

^Wherein, R 1 ~ ^{R 4,} ^{R 1} and ^{R 2} are each independently alkenyl radicals alkyl group or a carbon number of 8 to 10 8 to 10 carbon atoms and ^{R 3} and ^{R 4} is a methyl group Or R ¹ is a benzyl group, R ² is an alkyl group having 12 to 14 carbon atoms and R ³ and R ⁴ are methyl groups, or R ¹ is an alkyl group or carbon having 16 to 18 carbon atoms An alkenyl group of formulas 16 to 18, and R ² , R ³ and R ⁴ are methyl groups. X ⁻ represents a halogen ion or an alkyl sulfate ion. ]

In the formula (2), R ¹ to R ⁴ satisfy any of the following conditions (c1) to (c3).
(C1): R ¹ and R ² are each independently an alkyl group having 8 to 10 carbon atoms or an alkenyl group having 8 to 10 carbon atoms, and R ³ and R ⁴ are methyl groups. A dialkyldimethyl cation is preferred.
(C2): R ¹ is a benzyl group, R ² is an alkyl group having 12 to 14 carbon atoms, and R ³ and R ⁴ are methyl groups. A monoalkyl monobenzyldimethyl cation is preferred.
(C3): R ¹ is an alkyl group having 16 to 18 carbon atoms or an alkenyl group having 16 to 18 carbon atoms, and R ² , R ³ , and R ⁴ are methyl groups. A monoalkyltrimethyl cation is preferred.

In the formula (2), examples of the halogen ion as X ⁻ include a chlorine ion, a bromine ion, a fluorine ion, and an iodine ion. Examples of the alkyl sulfate as X ⁻ include alkyl sulfate ions having 1 to 3 carbon atoms represented by the following general formula (x1).
R ⁷ -SO ₄ ^- (x1)
[In the formula (x1), R ⁷ represents an alkyl group having 1 to 3 carbon atoms. ]
X ⁻ is preferably a chlorine ion, a bromine ion, an iodine ion, or an alkyl sulfate ion having 1 to 3 carbon atoms.

As a preferable specific example of the component (C) that satisfies the condition (c1), a didecyldimethylammonium salt mainly composed of a linear alkyl group having 10 carbon atoms (for example, “ARCARD 210” manufactured by Lion Akzo) ]) And the like.
Preferable specific examples of the component (C) satisfying the condition (c2) include benzalkonium chloride (for example, “Arcade CB” manufactured by Lion Akzo).
Preferable specific examples of the component (C) satisfying the condition (c3) include stearyltrimethylammonium salt in which R ¹ is a stearyl group (for example, “Arcade T-800” manufactured by Lion Akzo), and R ¹ is an octadecyl group. And octadecyltrimethylammonium salt.

As the component (C), one type may be used alone, or two or more types may be used in combination.
The content of the component (C) is preferably 0.01 to 1.5% by mass, more preferably 0.1 to 0.8% by mass, and more preferably 0.2 to 0% with respect to the total mass of the liquid detergent composition. More preferably, it is 8 mass%. When the content is 0.01% by mass or more, a sufficient thickening effect by the component (B) can be obtained, and the stability with time of the viscosity can be improved satisfactorily. Moreover, it is easy to obtain a good deodorizing effect. When the amount is 1.5% by mass or less, complex formation with the component (A) is likely to be suppressed. As a result, white turbidity of the liquid appearance is easily prevented and an appropriate viscosity of the liquid is easily obtained.

<(D) component>
Component (D) is a chelating agent. Known chelating agents can be used as sequestering agents in the field of cleaning agents. In the present invention, the stability of the viscosity of the liquid over time is improved by including the component (D). Although the reason is not clear, since the component (D) exhibits an anionic property in the liquid, it can form a complex with the component (C). Thereby, the formation of a complex of the component (B) and the component (C) is partly inhibited, and it is considered that the thickening effect by the component (B) can be sufficiently obtained.
Moreover, it is thought that the formation of a weak complex of the component (B), the component (C), and the component (D) makes it difficult for the network structure of the component (B) to be decomposed and the stability of viscosity with time is easily obtained. It is done.
Furthermore, since the formation of the complex of the component (B) and the component (C) is suppressed, the cloudiness of the liquid is also suppressed.

As the component (D), a chelating agent having a trivalent to tetravalent carboxylic acid group or a salt thereof is preferable. Specific examples thereof include citric acid, sodium citrate, and aminocarboxylic acid chelating agent. Aminocarboxylic acid is a compound containing in each molecule at least one carboxyl group and one monovalent functional group obtained by removing one hydrogen atom from ammonia, a primary amine, or a secondary amine. An aminocarboxylic acid chelating agent is a chelating agent that is an aminocarboxylic acid.
Of these, aminocarboxylic acid-based chelating agents are preferred in terms of viscosity stability after storage.
As the aminocarboxylic acid chelating agent, those known as chelating agents in the field of cleaning agents can be used. Specific examples include methyl glycine diacetate (MGDA), methyl glycine diacetate, L-glutamate diacetate (GLDA), L-glutamate diacetate, diethylenetriaminepentaacetic acid (DTPA), diethylenetriaminepentaacetate, ethylenediaminesuccinic acid. (EDDS), ethylenediamine succinate, 3-hydroxy-2,2'-iminodisuccinic acid (HIDS), 3-hydroxy-2,2'-iminodisuccinate, L-aspartic acid-N, N-2 acetic acid, L -Aspartic acid-N, N-2 acetate, etc. As a kind of salt, (sodium salt) is preferable. MGDA or a salt thereof is more preferable, and trisodium methylglycine diacetate is particularly preferable.

(D) 0.03 mass% or more is preferable with respect to the total mass of a liquid cleaning composition, 0.04 mass% or more is more preferable, and 0.06 mass% or more is further more preferable. When the content is 0.03% by mass or more, the effect of improving the liquid viscosity stability with time or the effect of preventing liquid turbidity due to the component (D) can be sufficiently obtained.
On the other hand, if the content of component (D) is too large, the effect of thickening the liquid by component (B) will decrease, so it is necessary to increase the amount of component (B) added to obtain an appropriate liquid viscosity. This increases the manufacturing cost. Further, even if the content of the component (D) exceeds 1.0% by mass, an increase in the viscosity stability with time is not increased, so that it is economically preferable to be 1.0% by mass or less. 6 mass% or less is more preferable, and 0.5 mass% or less is further more preferable. More specifically, it is preferably 0.03 to 1.0% by mass, more preferably 0.04 to 0.6% by mass, and 0.06 to 0.5% by mass. Further preferred.

<(E) component>
Component (E) is a water-soluble metal salt. As the water-soluble metal salt, a hydrate form can also be used.
Examples of the component (E) include water-soluble silver salts, water-soluble copper salts, water-soluble zinc salts, water-soluble iron salts, water-soluble manganese salts, water-soluble aluminum salts, and hydrates thereof.

[Detergency (Evaluation method of sebum dirt cleaning power)]
In this method, the reflectance of the cloth was measured using a color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd., product name: SE-2000), and the reflectance R was calculated from Hunter whiteness Z by the following formula.
R = Z / 100
First, the reflectance of 10 wet artificial soiled fabrics (purchased from the Laundry Science Association, hereinafter also referred to as contaminated fabrics) before washing was measured. Terg-O-Tometer (manufactured by U.S. Testing) was used as a cleaning tester. The washing liquid used was a liquid detergent composition for clothing dissolved in 900 mL of tap water at 25 ° C. to a concentration of 1000 ppm.
In the washing tank, 10 sheets of contaminated cloth and a charge cloth (a knitted cloth was cut finely, thoroughly washed and rinsed and dried), and a washing solution were put therein. The amount of charge cloth was set so that the bath ratio was 30 times.
After washing for 10 minutes at a rotation speed of 120 rpm and a temperature of 25 ° C., rinsing was performed twice with 900 mL of tap water at 25 ° C. for 3 minutes. Dried. The reflectance R of the contaminated cloth after drying (hereinafter also referred to as “cleaning cloth”) is measured using a 460 nm filter, and the cleaning ratio (unit:%) is rounded off according to the following formulas (i) and (ii). ) Was calculated. In the formula, K represents an extinction coefficient, S represents a scattering coefficient, and R represents a reflectance. The standard white cloth is an original white cloth (raw cloth) that is not stained, and the reflectance R of the standard white cloth is 80.

The initial viscosity was obtained by measuring the viscosity with a B-type viscometer. The measurement conditions of the viscosity were 30 ° C., 30 rpm, 30 seconds, No. 3 rotors were used. However, in the case of less than 1000 mPa · s, no. Two rotors were used.
If the initial viscosity was 80 mPa · s to 3000 mPa · s, it was judged as acceptable (◯).

[Viscosity stability]
60 g of the liquid detergent composition for clothing immediately after preparation was put in an SV50 bottle and stored at 60 ° C. for 2 or 6 months. After storage, after standing for 1 hour in a 30 ° C. water bath, the viscosity after storage was measured using a B-type viscometer. The viscosity measurement conditions were the same as the initial viscosity.
The rate of change in viscosity after storage with respect to the initial viscosity was determined by the following formula.
Viscosity change rate [%] = viscosity after storage [mPa · s] / initial viscosity [mPa · s] × 100

[Odor control]
Ten towels that were used at home for more than half a year and were used for about 7 days in normal life were used as test towels.
The test towel was subjected to a washing process (water temperature of about 25 ° C., tap water was poured, bath ratio was 30 times) in a normal course of a washing machine (product name: JW-Z23A type, manufactured by Haier). At that time, the input amount of the liquid detergent composition for clothes to the washing machine was 30 g / 30 L of tap water (1000 ppm).
A new 100% cotton skin shirt (manufactured by BVD) as a charge cloth for bath ratio matching is pre-washed in an automatic course of a fully automatic washing machine (manufactured by Matsushita Electric Industrial Co., Ltd., product name: NA-F70SD1). (Water temperature is about 25 ° C., tap water is poured). In this preliminary washing treatment, a commercially available synthetic detergent top (product name, manufactured by Lion Corporation) was used as a detergent, and the amount of detergent used per wash was 25 g / 30 L of tap water.

After washing the test towel, the test towel was dried in a room with a room temperature of about 25 ° C. and a relative humidity of 90% RH and dried for 8 hours. After that, 6 expert panelists performed sensory evaluation to smell 10 test towels after washing and drying (indoor drying).

In the evaluation criteria (b), ◎ and ○ were accepted.
Evaluation criteria (b)
◎ (Pass): Score ≦ 1.0 point ○ (Pass): 1.0 point <Point ≦ 2.0 point Δ (Pass): 2.0 point <Point ≦ 3.0 point × (Fail): 3 .0 <score

As shown in the results of Tables 1 and 2, the liquid detergent compositions for clothes of Examples 1 to 15 have good detergency and antibacterial properties, as well as good viscosity and viscosity stability.
In particular, Example 1 and Example 11, Example 13 and Example 15 are compared. In Example 1 and Example 13 using an aminocarboxylic acid-based chelating agent, compared to Examples 1 and 15 using citric acid as the component (D), The higher the initial viscosity, the less the change in viscosity during storage, and the excellent storage stability.

Example 21 was a comparative example containing no component (A), and had a poor initial appearance, insufficient detergency, and a low initial viscosity. Moreover, the odor suppression effect was also insufficient. Since the initial viscosity is low, the viscosity stability is not evaluated.
Example 22 was a comparative example containing no component (B), and the initial viscosity was low. Therefore, viscosity stability is not evaluated. The viscosity “10>” in the table means that the initial viscosity is less than 10.
Example 23 was a comparative example containing no component (C), and the effect of suppressing odor was insufficient.
Example 24 is a comparative example containing no component (D), and the initial viscosity is good, but the viscosity decrease with time is large and the viscosity stability is poor.
Example 25 is a comparative example that contains the component (C) but does not contain the component (D), and has a large viscosity decrease with time and poor viscosity stability.
Examples 26 and 27 contained the components (A) to (D), but the viscosity stability was insufficient because the content of the component (D) was as small as 0.01% by mass.
