2. Description of the Related Art Dirt on the floor, walls and utensils of bathtubs and bathrooms is composed of organic substances such as fatty acid metal salts (mainly calcium salts), free fatty acids, glycerides, and nitrogen-containing compounds, and inorganic substances such as mud. Consists of a mixture of Conventionally, as a cleaning agent for removing such dirt,
An acidic detergent containing an acidic substance, hydroxycarboxylic acid, a surfactant, and a water-soluble solvent is known (JP-A-52-77111). However, it has been pointed out that this acidic cleaning agent, although having a cleaning effect, damages hard surface materials such as tile joints and aluminum sashes. The use of an alkaline cleaning agent has also been proposed, but has the drawback that it is insufficient in the effect of removing dirt and affecting the material. On the other hand, a hard surface detergent comprising a combination of a surfactant and a sequestering agent, and a hard surface detergent comprising a combination of a surfactant, a sequestering agent and a solvent have been developed. JP-A No. 52-76308, 53-35710

No. 500, JP-A-2-298599, JP-A-6-322398, and JP-A-7-18294.
However, detergents containing these sequestering agents have insufficient detergency when actually used. Therefore, if the addition ratio of a surfactant, a sequestering agent, or the like is increased in order to improve the detergency, there is a problem that the material of the hard (for example, FRP bath) surface is damaged.

[0003]

An object of the present invention is to provide a liquid detergent composition which has an excellent cleaning effect on stains of fatty acid metal salts and does not damage hard surfaces.

[0004]

Means for Solving the Problems As a result of intensive studies, the present inventors have combined a surfactant, a solvent, a sequestering agent and a sulfate in a specific ratio, and adjusted the pH of the composition to a predetermined value. The inventors have found that the above problems can be solved by adjusting the content within the range, and have completed the present invention.

That is, the present invention relates to (A) surfactant 0.1
-10% by weight, (B) solvent 0.1-30% by weight, (C)
0.1 to 20% by weight of one or more sequestering agents, (D) water-soluble or poorly water-soluble inorganic sulfate 0.1
A liquid detergent composition comprising: 10 to 10% by weight, and (E) a balance of water, and having a pH of 5 to 11.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One of the components constituting the liquid detergent composition of the present invention is a surfactant (A). As the surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant, a nonionic surfactant, or the like can be used, and is not particularly limited. Representative examples are as follows, and these can be used alone or in combination of two or more. (1) Anionic surfactant Specific examples of the anionic surfactant include alkyl sulfates, alkyl polyoxyethylene sulfates, alkyl benzene sulfonates, α-olefin sulfonates, fatty acid salts, and ether carboxylic acids. Salts and monoalkyl phosphates. Examples of counter ions (cations) of these anionic surfactants include alkali metal ions, alkaline earth metal ions, alkanolamine ions, and ammonium ions. (2) Cationic surfactant Specific examples of the cationic surfactant include an alkyltrimethylammonium salt, a dialkyldimethylammonium salt, an alkylammonium salt, and an alkylbenzyldimethylammonium salt. Examples of the counter ion (anion) of these cationic surfactants include a halogen ion. (3) Amphoteric surfactant Specific examples of the amphoteric surfactant include alkylcarboxybetaine and alkylsulfobetaine. (4) Nonionic surfactant Specific examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, fatty acid diethanolamide, amine oxide, amidoamine oxide and the like.

The ratio of the surfactant to the detergent composition is 0.1 to 10% by weight, preferably 0.5 to 7% by weight.
Range. If the amount of the surfactant is less than 0.1% by weight, the dispersing action and the solubilizing action on the soil are weak, and the other components of the liquid detergent composition of the present invention, such as a solvent, a sequestering agent and an inorganic sulfuric acid. Interaction with salts also does not yield satisfactory results. On the other hand, when the amount is more than 10% by weight, a special effect of improving the detergency is not brought about, but rather the bubbles are cut off and the rinsing property is deteriorated, which is not preferable.

[0008] One of the components constituting the liquid detergent composition of the present invention is a solvent (B). As the solvent, those generally used in liquid detergents can be used, and are not particularly limited, but compounds represented by the following general formula (1) are preferable. R ₁ O ｛(C ₂ H ₄ O) m (C ₃ H ₆ O) n｝ H (1) (wherein, R ₁ represents an alkyl group or an aromatic group having 1 to 4 carbon atoms, and m and n Are each 0 to 3 and are not 0 at the same time. When m and n are larger than 0 in {}, the oxyethylene group and the oxypropylene group are bonded in random and / or block form. Examples of the solvent represented by the above formula (1) include ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, propylene glycol diethylene glycol monobutyl ether, dipropylene glycol ethyne glycol monobutyl ether,
Examples include ethylene glycol monophenyl ether and triethylene glycol monophenyl ether. These solvents may be used alone or in combination of two or more.

The ratio of the solvent to the detergent composition is 0.1%.
It is 1 to 30% by weight, preferably 5 to 15% by weight.
When the amount is less than 0.1% by weight, the detergency is insufficient, and the interaction with the other components of the liquid detergent composition of the present invention, such as a surfactant, a sequestering agent, and an inorganic sulfate. The effect cannot be obtained sufficiently. On the other hand, if the amount is more than 30% by weight, the effect of increasing the amount is not seen and it is uneconomical.

One of the components constituting the liquid detergent composition of the present invention is a sequestering agent (C). Specific examples of the sequestering agent include ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid, N-hydroxyethylethylenediaminetriacetic acid, ethylenediaminetetrapropionic acid, triethylenetetraminehexaacetic acid, ethyleneglycoldietherdiaminetetraacetic acid, and cyclohexane-1. , Aminocarboxylic acids such as 2-diaminetetraacetic acid, and acetic acid, adipic acid, glycolic acid, diglycolic acid, monochloroacetic acid, oxydisuccinic acid, carboxymethyloxysuccinic acid, citric acid, lactic acid, tartaric acid, oxalic acid, malic acid, Lower carboxylic acids such as gluconic acid, carboxymethylsuccinic acid and carboxymethyltartaric acid are exemplified. These are potassium hydroxide,
It is also possible to neutralize a part or all of the carboxyl groups with sodium hydroxide, ammonium hydroxide, monoethanolamine, diethanolamine, morpholine, or the like, and to mix as a water-soluble salt. These sequestering agents may be used alone or in combination of two or more.

The ratio of the sequestering agent to the detergent composition is in the range of 0.1 to 20% by weight, preferably 1 to 10% by weight. When the amount is less than 0.1% by weight, the detergency is insufficient, and the interaction with the surfactant, solvent and inorganic sulfate, which are other additional components of the liquid detergent composition of the present invention, also occurs. We cannot get enough results.
On the other hand, if the amount is more than 20% by weight, no remarkable effect is obtained, and it becomes uneconomical.

One of the components constituting the liquid detergent composition of the present invention is a water-soluble or poorly water-soluble inorganic sulfate (D).
It is. Specific examples of the inorganic sulfate include sodium sulfate, potassium sulfate, ammonium sulfate, and magnesium sulfate. These can be blended in the form of a salt. For example, in the case of sodium sulfate, it is also possible to blend both of sulfuric acid and sodium hydroxide to cause a neutralization reaction.

The proportion of the water-soluble or poorly water-soluble inorganic sulfate to the detergent composition is in the range of 0.1 to 10% by weight, preferably 3 to 7% by weight. 0.1% by weight
If it is less than 30, the detergency is insufficient, and a sufficient result cannot be obtained even in the interaction with a surfactant, a solvent and a sequestering agent which are other additional components of the liquid detergent composition of the present invention. . On the other hand, when the amount is more than 10% by weight, the compounding results in the deterioration of the stability at low temperature of the liquid detergent composition.

The pH of the liquid detergent composition of the present invention is 5-1.
It is in the range of 1, preferably 6-9. PH of the composition is 5
In the ranges of less than 11 and in the range of more than 11, the cleaning power is relatively excellent, but in some cases adversely affects the object to be cleaned. In order to keep the pH within this range, the pH can be adjusted with an alkaline agent such as sodium hydroxide, potassium hydroxide or ammonium hydroxide and an acidic substance such as sulfuric acid or meta-xylene sulfonic acid.

In the present invention, other optional components can be appropriately compounded as needed. Optional components include lower alcohols, lower alkyl benzene sulfonic acids or salts thereof, hydrotropes such as ethylene glycol, bactericides, preservatives, and fungicides, which are blended to maintain liquidity at low or high temperatures. , Fragrances, dyes, antioxidants,
There are thickeners and UV absorbers. In addition, the compound used for these optional components can be used as long as it is generally used for a detergent, and is not particularly limited.

EXAMPLES In order to confirm the effects of the examples, which are specific examples of the liquid detergent composition of the present invention, various tests were carried out on the detergency against scale stains and the effect on the articles to be washed. The specific operations of these tests are as follows. (1) Detergency against scales Spray the liquid detergent composition (stock solution) on a polypropylene bathtub (used for 2 months) to which scales that cannot be easily removed by rubbing are adhered, and clean the surface of the bath. 20g
/ Cm ² with a urethane sponge with a load of 5
The state of removal of rubbing and dirt is visually judged based on the following criteria. The criteria are as follows. 5 points: Very good dirt removal 4 points: Good dirt removal 3 points: There is unevenness in dirt removal 2 points: Some extent of dirt removal 1 point: Almost no dirt removal

(2) Influence test on articles to be washed A joint, an aluminum plate, and a fiber reinforced plastic (FRP) are immersed in the detergent composition for 24 hours, and the state of the surface is visually judged according to the following criteria. The criteria are as follows. ：: no change is observed at all △: slight change is observed ×: change is clearly observed

Examples 1 to 8 and Comparative Examples 1 to 8 Table 1 shows examples of the liquid detergent composition of the present invention. or,
Table 2 shows a comparative example. In order to confirm the effects of the examples of the present invention, a cleaning test for the descaling and an effect test for the washing object were performed. Tables 1 and 2 also show the results of this test.

[0021]

[Table 1]

[0022]

[Table 2]

As is apparent from Table 1 above, all the liquid detergent compositions containing the components of the present invention in a predetermined amount and exhibiting a pH within a predetermined range exhibit excellent performance. . On the other hand, as shown in the results of Table 2, when the pH is not in the predetermined range, even if the detergency is relatively excellent in terms of detergency, it has the effect of affecting the object to be washed, Inferior in this respect (Comparative Example 1,
2). In addition, when the inorganic sulfate as the component (D) was not added, the detergency against scale was inferior (Comparative Example 3). In order to improve the detergency, a surfactant, a solvent, and metal ion sequestration were used. When the amount of the agent is increased, the detergency is certainly improved, but the effect is left on the object to be washed (Comparative Example 4). In addition, if any of the surfactant, the solvent, and the sequestering agent is not blended, the detergency against scale is poor (Comparative Examples 5, 6, and 7).

[0024]

The liquid detergent composition of the present invention has a particularly excellent detergency against scale stains adhering to a bathtub, a scale, a stool, a pen, or a washing place in a bathroom. It does not damage the hard surface during use.
