Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition for dwelling, and more particularly to a liquid detergent composition suitable for cleaning floor and wallpaper surfaces using a resin such as polyvinyl chloride. About.

[0002]

2. Description of the Related Art Conventional household detergents include nonionic surfactants such as polyoxyethylene alkyl ether, sodium alkylphenoxyphenyldisulfonate, α
-A detergent containing an anionic surfactant such as an olefin sulfonate and a solvent is used (for example, JP-A-3-182596).

On the other hand, in recent homes, floors and wallpapers using resin such as polyvinyl chloride are often used, but dirt is likely to adhere to floors and wallpapers made of polyvinyl chloride. In addition, many resin floors and wallpapers have irregularities on the surface for design and anti-slip function. A cleaning agent having detergency has been desired.

[0004]

DISCLOSURE OF THE INVENTION In view of the above problems, the present invention provides a liquid detergent composition for residential use which uses a resin such as polyvinyl chloride and has a high detergency against stains on the floor and wallpaper surfaces. I do.

[0005]

The liquid detergent composition for dwelling of the present invention comprises the following (a), (b), (c) and (d), and (a) and (b): 0.5 to 7 parts by weight, (c) 1 to 10 parts by weight, (d) 1 to 10 parts by weight, and the weight ratio of (a) and (b) is (a) / (b) = 1/9
９9/1. (A) an alkyl sulfate having 10 to 16 carbon atoms in an alkyl group and 1 to 5 moles of ethylene oxide added thereto (b) an alkyl sulfate having 8 carbon atoms and 1 to 5 moles of ethylene oxide added thereto (C) sodium meta-xylene sulfonate (d) diethylene glycol monoalkyl ether having 1 to 4 carbon atoms in the alkyl group

[0006] The liquid detergent composition for residential use of the present invention penetrates strongly into soil by the combination of the components (a), (b) and (c), and solubilizes the soil by the action of the component (d). Therefore, it has a high detergency against stubborn dirt on the floor and wallpaper surface.

The component (a) used in the present invention comprises an alkyl group having 10 to 16 carbon atoms and an ethylene oxide having 1 to 10 carbon atoms.
It is an alkyl sulfate salt having 5 moles added, and preferably has 12 to 14 carbon atoms in the alkyl group. Also,
The neutralized salt is preferably sodium, potassium or ethanolamine.

The component (b) used in the present invention is an alkyl sulfate salt in which the alkyl group has 8 carbon atoms and 1 to 5 mol of ethylene oxide is added, and the alkyl group is preferably 2-ethylhexyl. The neutralized salt is preferably sodium, potassium or ethanolamine.

The component (c) used in the present invention is sodium meta-xylene sulfonate.

The component (d) used in the present invention is a diethylene glycol monoalkyl ether having an alkyl group having 1 to 4 carbon atoms. Examples of the component (d) include diethylene glycol monoethyl ether, diethylene glycol monopropyl ether, diethylene glycol monobutyl ether, diethylene glycol isobutyl ether, and the like. Diethylene glycol monoethyl ether is preferably used.

In the cleaning composition of the present invention, (a)
The component and the component (b) are blended so that the total amount is 0.5 to 7 parts by weight, the component (c) is 1 to 10 parts by weight, and the component (d) is 1 to 10 parts by weight.

When the total of the components (a) and (b) is less than 0.5 parts by weight, the effect of cleaning dirt is not sufficient. Therefore, it becomes difficult to wipe off.

When the component (c) is less than 1 part by weight,
If the cleaning effect on dirt is not sufficient and exceeds 10 parts by weight, the solution becomes unstable.

When the component (d) is less than 1 part by weight,
If the cleaning effect on dirt is not sufficient and exceeds 10 parts by weight, no improvement in the effect by increasing the amount is observed.

The weight ratio of component (a) to component (b) is
(A) / (b) = 1/9 to 9/1, and preferably (a) / (b) = 3/7 to 7/3. (A) /
When (b) is less than 1/9 or more than 9/1, the effect of cleaning dirt is not sufficient.

The cleaning composition of the present invention comprises (a)
(B), (c), and (d) are contained as essential components, and water, alcohol, and the like are blended and used in addition thereto. In a solution to which water, alcohol, or the like is added, the total of (a) and (b) is 0.5 to 7% by weight, (c) 1 to 10% by weight, (d) 1
Preferably, the amount is from 10 to 10% by weight.

The pH value of the cleaning composition of the present invention is as follows:
Although it is not particularly limited, it is desirable to be in the range of 7.0 to 12.0.

Further, in the present invention, in addition to the above essential components, known components used in ordinary household liquid detergents, such as fragrances, antibacterial agents, polishing agents, water repellent agents, antistatic agents, etc. Additives such as deodorants and insect repellents can be blended as long as the effects of the present invention are not impaired.

The cleaning composition of the present invention is particularly effective for cleaning resin floors and wallpaper. Examples of the resin include polyvinyl chloride, polyethylene, polypropylene, polyurethane, polycarbonate and the like, and are particularly suitable for polyvinyl chloride. In addition, since the liquid cleaner composition for residential use of the present invention has a strong penetrating power and penetrates into wood or tatami mats, it is suitable for use in resin products such as polyvinyl chloride.

(Examples 1 and 2 and Comparative Examples 1 and 2) Table 1
The liquid detergent composition was prepared according to the formula shown below, and the following evaluation was performed.

<Evaluation of Detergency 1> Using the prepared liquid detergent composition, the temperature of the washing water was 25 ° C., and the amount of the detergent composition used was 1
Under a condition of 0 g / water 1 L, the artificial wet-stained cloth (commercially available from the Japan Laundry Chemistry Association) is washed with a stirring-type detergency tester Terg-O-Tometer. The washing rate was calculated from the difference. . Washing rate (%) = (Rw−Rs) / (Ro−Rs) × 10
0 Rw: Surface reflectance of the contaminated cloth after cleaning Rs: Surface reflectance of the contaminated cloth before cleaning Ro: Surface reflectance of the original white cloth before the contamination

<Evaluation of Detergency 2> The adjusted liquid detergent composition was sprayed on a cushion floor made of polyvinyl chloride which had been stained by use at home using an automatic sprayer.
After leaving for 1 minute in this state, the rag washed with water was squeezed tightly and wiped with water. The degree of washing was visually determined.
Table 1 shows the determination results. The criteria are as follows. ○ Dirt was completely cleaned. △ Some remaining stains were observed. × No cleaning action was observed.

[Table 1]

[0023]

The liquid detergent composition for residential use according to the present invention has a strong penetrative power and a property of solubilizing dirt. Therefore, a resin such as polyvinyl chloride, which is difficult to remove dirt with a conventional detergent, is used. Demonstrates excellent detergency against dirt on the floor and wallpaper surfaces.
