DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning agent for cleaning solid surfaces, and more particularly to cleaning solid surfaces such as exterior walls and floors of buildings, furniture and appliances for home use, kitchen and kitchen appliances, and automobiles. The present invention relates to a detergent composition which is sprayable, convenient and excellent in detergency, which is suitable as a detergent for the cleaning.

[0002]

2. Description of the Related Art Conventionally, "household detergents" and "range cleaners" having a spraying type cleaning liquid for cleaning a solid surface have been commercially available. In addition, there is also known a nozzle in which the cleaning liquid is improved so that the cleaning liquid is not scattered at the time of spraying so that the cleaning liquid can be sprayed in a foam state.

[0003]

By the way, the cleaning liquid is
When the viscosity is low, so-called "liquid dripping" occurs when used on a vertical surface, for example. When liquid dripping occurs, not only is the immersion effect difficult to appear, but also the required amount of the cleaning liquid does not remain in the required places, so that the cleaning performance is poor and a large amount of the cleaning agent is used, resulting in poor economic efficiency. . Therefore, it is conceivable to use a water-soluble thickener to increase the viscosity of the cleaning solution,
If a water-soluble thickener is used, spraying by a spray nozzle becomes impossible.

In the prior art, it was not possible to increase the viscosity of the cleaning liquid without hindering spraying by the injection nozzle. In addition, the conventional jet-type cleaning liquid generally does not contain a component having an abrasive effect, and it cannot be expected that physical cleaning power can be expected. Therefore, it is an issue to increase the viscosity of the cleaning liquid to prevent liquid dripping without hindering the spraying property, to enhance the immersion effect, to provide physical cleaning power, and to improve the cleaning performance and economic efficiency. It is. An object of the present invention is to solve such a problem.

[0005]

As a result of intensive studies, the present inventors have found that the use of a water-absorbent resin can increase the viscosity without impairing the sprayability of the cleaning liquid. In addition, the water-absorbent resin reduces the water absorption in direct proportion to the concentration of the inorganic salts, but the water-absorption resin in physiological saline has a certain amount or more of water-absorbing performance, so the viscosity of the washing liquid is required. It has been found that it can be raised to a level and that spraying is also possible, leading to the completion of the present invention.

[0006] The water-absorbing resin is preferably contained in the washing solution in an amount of 0.2 to 3.0%, more preferably 0.3 to 1.0%.

The water-absorbing resin preferably has a water-absorbing capacity of 30 g / g or more in physiological saline.
For example, among cross-linked polyacrylate, isobutylene-maleate, starch-polyacrylate, polyvinyl alcohol-polyacrylate, cross-linked polyvinyl alcohol, and carboxymethyl cellulose-polyacrylate It is preferable to use one or two or more selected from the above, and among them, a crosslinked polyacrylate and a starch-polyacrylate are preferred.

The liquid detergent composition of the present invention contains a predetermined amount of a water-absorbent resin in the cleaning solution, so that the viscosity of the cleaning solution is increased and liquid dripping hardly occurs, so that the immersion effect is improved, and As a result, a necessary amount of the cleaning liquid remains in a required place, so that the cleaning property is improved and the economic efficiency is also improved. In addition, the water-absorbing resin increases the viscosity of the cleaning liquid to prevent liquid dripping, but does not hinder the sprayability of the injection nozzle. In addition, since the water-absorbing resin is present as a gel-like insoluble matter, a detergency by a physical action is obtained, and the detergency is further improved. For this reason, it is suitable as a cleaning liquid to be wiped off or washed off after being left for a certain period of time after spraying, and is used as a “range cleaner”, “house detergent”, “car shampoo”,
It can be suitably used as a "paint remover" or the like.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The liquid cleaning composition of the present invention improves the performance as a jet-type cleaning liquid by using a conventional cleaning liquid as it is and adding a water-absorbing resin thereto. Nonionic surfactants used as wetting agents, penetrants, dispersants, emulsifiers, solvents, leveling agents, bactericides, etc., anionic surfactants, cationic surfactants, amphoteric surfactants Agents, etc. can be used as cleaning agents, and furthermore, as a cleaning power enhancer, inorganic and organic alkalis, water-soluble and oil-soluble organic solvents, ultraviolet absorbers, preservatives, sequestering agents, pigments, fragrances, etc. Or one or more of these.

The water-absorbing resin to be added has a water-absorbing capacity of not less than 30 g / g in physiological saline, and is a crosslinked polyacrylate, isobutylene-maleate, starch-polyacrylic acid. One or more of salt, polyvinyl alcohol-polyacrylate, cross-linked polyvinyl alcohol, and carboxymethyl cellulose-polyacrylate are used. Among them, crosslinked polyacrylates and starch-polyacrylates are preferred. And, the content of the water-absorbing resin is 0.2 to 3.0%, preferably 0.3 to 1.0%.

The test method in the case of Table 2 is as follows.

Liquid dripping test The test method is the same as that in Table 1 and the evaluation criteria are the same.

Detergency test as a range cleaner A soybean oil containing 2% of activated carbon was evenly and thinly applied to a 5 cm × 10 cm stainless plate, and then heated in an oven at 170 ° C. for 1 hour to remove model soil. Board. And
The model soiled plate is held vertically, and the washing liquid is sprayed once from a position 10 cm away, left for 3 minutes, and then wiped off with a minimum force. Then, the detergency is evaluated according to the same criteria as in Table 1 based on the degree of dirt removal when visually observed.

In Examples 6 to 9 as range cleaners shown in Table 2, the water-absorbing resin was 0.2 to 3.0%, all of which were sprayable and had no liquid dripping. Detergency is also superior to Examples 6-10. When the water-absorbing resin exceeds 3.0, spraying cannot be performed as shown in Comparative Example 10. In addition, the mixing ratio of the water-absorbing resin also increases, the spray resistance increases, and the spray state deteriorates. The spray resistance is low and a good spray state is maintained when the water-absorbent resin is blended in an amount of 0.2 to 1.0%. Also in this case, in order to prevent liquid dripping, the water-absorbing resin is preferably at least 0.3%.

The dripping of the cleaning liquid is easily affected by conditions such as the material of the solid surface, the type of dirt, the state of wetting, and the location of the cleaning surface (wall, ceiling, etc.). In addition, the amount of the water-absorbing resin may be changed so as to have an optimum viscosity according to the intended use, whereby the convenience can be further improved.

Although the embodiments in the case of a household detergent and a range cleaner have been described above, the present invention is not limited to the above-described embodiments. It can be used as a cleaning agent for use, and can be made into a concentrated product from the viewpoint of resource saving.

[0047]

According to the present invention, by using a water-absorbent resin, the viscosity of the cleaning liquid is increased without impairing the spraying property, the liquid is prevented from dripping, and the immersion effect is enhanced to improve the cleaning performance and economic efficiency. Can be done. Further, the detergency can be further improved by physical detergency due to the presence of the water-absorbent resin as a gel-like insoluble matter.
