Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent for a house or furniture which can be widely used for houses such as floors, walls, glass surfaces, electric appliances and the like and which can be washed only by an operation of wiping off dirt on an object to be washed. It relates to a suitable neutral liquid detergent composition.

[0002]

2. Description of the Related Art Conventionally, household cleaning agents have been used for furniture,
It is widely used for various purposes such as glass and oil stains, toilets and bathrooms. In particular, for furniture and glass, weak alkaline or alkaline synthetic detergents have been the mainstream.

[0003] As these alkaline range cleaning agents,
For example, JP-A-3-41200, JP-A-5-503
No. 547 discloses a detergent comprising an alkaline substance such as an alkanolamine, an amphoteric surfactant and an anionic surfactant ammonium salt. When using,
Diluted in water and wiped with dirt, mop, etc. to wipe off the dirt attached to the item to be washed. Sprayed directly on the item to be washed, or used on a rag etc. Two types of cleaning agents for wiping are widely marketed, and recently, a spray-type cleaning agent using a trigger container has become mainstream.

[0004] The performance requirements of these residential spray cleaners are their detergency to remove various soils in the home and no wiping marks after use. As for detergency, using alkaline volatiles such as monoethanolamine,
The cleaning component evaporates after use, leaving no trace of wiping, and has high cleaning performance.

[0005] Further, there has been known a liquid detergent in which a specific surface active agent is blended to eliminate traces of wiping.
For example, Japanese Patent Application Laid-Open No. 5-239492 discloses that when a detergent composition containing a surfactant, a volatile or liquid amine compound and water has a high concentration of 90% by weight or more, a hexagonal or lamellar liquid crystal is obtained. Discloses that the cleaning composition has the effect of leaving no wiping marks. Further, as a household cleaner composition free from uneven wiping, JP-A-63-309594 discloses a liquid detergent composition comprising a betaine-type amphoteric surfactant and / or an alkylammonium-type cationic surfactant. I have.

However, highly volatile alkaline agents such as alkanolamines described in these publications have a disadvantage that they have a strong odor, so that the odor remains during and after use. In addition, the alkaline cleaning composition has drawbacks that involve dangers, such as obliging the use of gloves for cooking rice and the like, and getting into the skin and eyes. Further, at present, a detergent composition containing an amphoteric surfactant or the like does not sufficiently exhibit the effect of remaining traces of wiping.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and aims to solve the problem.
For various types of dirt to be wiped, it has excellent cleaning performance by only wiping operation, and since it is in a neutral region, there is no adverse effect on the object to be washed, hands and skin, and there is no trace of wiping. It is an object of the present invention to provide a neutral liquid detergent composition suitable for home use or furniture use.

[0008]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems of the prior art, etc., and as a result, they have a specific nonionic surfactant and a neutral region. By doing so, it is possible to exhibit excellent cleaning performance against various soils in a house, and to obtain a neutral liquid detergent composition having the above-mentioned purpose without wiping marks, and to complete the present invention. It has been reached. That is, the present invention resides in a neutral liquid detergent composition containing a sucrose fatty acid ester and a glycerin fatty acid ester and being neutral.

[0009]

Embodiments of the present invention will be described below in detail. The neutral liquid detergent composition of the present invention (hereinafter, simply referred to as “liquid detergent composition”) contains sucrose fatty acid ester and glycerin fatty acid ester and is neutral. is there.

In the liquid detergent composition of the present invention, it is necessary to use a sucrose fatty acid ester and a glycerin fatty acid ester in order to enhance the cleaning performance and exhibit a property of no wiping residue. The sucrose fatty acid ester and glycerin fatty acid ester to be used are not particularly limited, but specifically, sucrose fatty acid esters include sucrose (having 8 to 18 carbon atoms, hereinafter simply referred to as “C8
-18 "etc.) mono fatty acid ester, sucrose (C8
-18) difatty acid esters, sucrose (C8-18) trifatty acid esters and the like. Examples of glycerin fatty acid esters include C6-18 fatty acid monoglyceride,
6-18 fatty acid diglycerides, C6-18 fatty acid triglycerides, glycerin acetate fatty acid esters, glycerin lactic acid fatty acid esters, glycerin citrate fatty acid esters, glycerin succinate fatty acid esters, glycerin diacetyltartaric acid fatty acid esters, and glycerin acetate. Preferred sucrose fatty acid esters are selected from sucrose (C10-14) monofatty acid esters and sucrose (C10-14) difatty acid esters.
Species or a mixture of two or more. Further, as the preferred glycerin fatty acid ester, one or a mixture of two or more selected from C6 to C10 fatty acid monoglycerides and C6 to C10 fatty acid diglycerides is suitable.

In the present invention, the intended liquid detergent composition can be obtained by containing the above-mentioned sucrose fatty acid ester and glycerin fatty acid ester. When the sucrose fatty acid ester alone or the glycerin fatty acid ester alone is used, the intended liquid detergent composition cannot be obtained. Further, those containing a sucrose fatty acid ester and a polyglycerin fatty acid ester have poor wettability to the object to be washed and poor cleaning performance (this point will be further described in Examples and the like).

The total amount of the sucrose fatty acid ester and the glycerin fatty acid ester is 0.01 to 2% by weight, preferably 0.1 to 1% by weight, based on the total amount of the liquid detergent composition. Is preferred. The ratio (weight ratio) of sucrose fatty acid ester to glycerin fatty acid ester
Is preferably 99: 1 to 60:40, and more preferably 95: 5 to 70:30. It is preferable to mix the glycerin fatty acid ester in the range of 1 to 40% by weight based on the sucrose fatty acid ester. If the total amount of the sucrose fatty acid ester and the glycerin fatty acid ester is less than 0.01% by weight, no improvement in detergency is observed, and if it exceeds 2% by weight, a problem is left in wiping marks, which is not preferable. If the glycerin fatty acid ester is mixed in less than 1% by weight with respect to the sucrose fatty acid ester, the wettability to the object to be washed is poor. This causes a problem with traces, which is not preferable.

[0013] The liquid detergent composition of the present invention preferably contains a chelating agent in order to further exhibit excellent cleaning performance against various soils in a house in a neutral region. The chelating agent to be used is not particularly limited as long as it has the ability to chelate metal ions.For example, formic acid, monocarboxylic acids such as acetic acid, oxalic acid, malonic acid, dicarboxylic acids such as succinic acid, and tricarballylic acid Polycarboxylic acids such as propane-1,1,2,3, tetracarboxylic acid, glycolic acid, tartaric acid, citric acid,

[0029]

[Table 1]

As shown in Table 1 above, Examples 1 to 8 which fall within the scope of the present invention have superior detergency and hardly any traces of wiping, as compared with Comparative Examples 1 to 7 which fall outside the scope of the present invention. Moreover, it was found that the wettability was excellent. In addition, since the pH was set to neutral 7, there was no sliminess or blemishes, and there was no adverse effect on the object to be washed, hands and skin. Specifically, Examples 1 to 8 are neutral liquid detergent compositions containing sucrose fatty acid esters and glycerin fatty acid esters, and having a neutral pH of 7, and thus have excellent detergency.
It turns out that there is almost no wiping trace residue, and it is excellent in wettability. On the other hand, in Comparative Examples 1 to 4, p
Since H is in the neutral region, there is no sliminess or kissiness, and there is no adverse effect on the object to be washed, hands and skin, but Comparative Example 1 shows the case where sucrose fatty acid ester alone is used.
Comparative Example 2 shows the case of using glycerin fatty acid ester alone,
Comparative Examples 3 and 4 are cases other than the nonionic surfactant. In these cases, it can be seen that all of the detergency, wiping residue and wettability cannot be satisfied. In Comparative Examples 5 and 6, the pH was 2.5 (acid range), respectively.
It is 0 (alkaline range), it has lubricity and squeaking properties, and it can be seen that it does not satisfy all of detergency, wiping residue and wettability. Comparative Example 7 containing the sucrose fatty acid ester and the polyglycerin fatty acid ester had poor wettability to the object to be washed and was inferior in cleaning performance. As is clear from the results of the above Examples 1 to 8 and Comparative Examples 1 to 7, the sucrose fatty acid ester and the glycerin fatty acid ester are contained and neutralized, whereby the cleaning power is excellent for the first time, and the wiping marks are obtained. It was found that there was almost no residue and the liquid detergent composition had excellent wettability.
