DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent-impregnated article particularly suitable for cleaning hard surfaces, and more particularly, to a method in which solid particles do not separate, settle, or float in a substrate even after long-term storage. The present invention relates to a detergent-impregnated article which can be dispersed stably.

[0002]

2. Description of the Related Art As a method for cleaning hard surfaces such as glass and automobile bodies, a liquid cleaning agent containing a surfactant and an alkali agent is sprayed on the hard surface. After spraying, the cleaning agent is generally wiped off with a wet cloth and further wiped dry with a dry cloth. In this method, after the dry wiping, the cleaning agent, the dirt component, the lint, and the like are left on the hard surface as dry wiping unevenness. Had become.

Further, as a lens cloth for eyeglasses, a lens cloth made of ultrafine fibers is known. This cloth removes dirt by taking in dirt components between ultrafine fibers without using a cleaning agent. Accordingly, although there is a cleaning effect on dirt components such as oils such as sebum adhering to the lens surface, a cleaning effect on dirt components firmly adhering to the surface cannot be expected. Further, since the cloth is composed of ultrafine fibers, the cloth has a high coefficient of friction with the surface and requires a large force when wiping. Therefore, the cloth is not suitable for lightly wiping a large surface such as a window glass.

With respect to a liquid detergent impregnated in a base sheet, a water-insoluble solid particle such as an abrasive or a opaque agent such as a synthetic resin emulsion is blended for the purpose of enhancing the detergency. Techniques for giving a feeling are known. In such a solid-dispersed liquid detergent, it is generally practiced to increase the viscosity of the detergent to stabilize the dispersion of solid particles and maintain a uniform dispersion state. However, in order to disperse solid particles having a large specific gravity or solid particles having a relatively large particle size, the viscosity of the detergent must be extremely high, and as a result, the substrate sheet is impregnated with the detergent. And the cleaning agent is difficult to come out of the base sheet during cleaning. Also,
Even if the cleaning agent could be applied to the hard surface, the workability was inevitably deteriorated due to poor spreadability of the cleaning agent on the hard surface and time required for wiping solid particles. On the other hand, if the viscosity of the cleaning agent is kept low, the solid particles may separate, settle, or float in the base sheet after being stored for a long period of time. There were problems such as that the cleaning performance did not come out and the cleaning performance was uneven between the front and back of the base sheet.

Accordingly, it is an object of the present invention to provide a detergent-impregnated article in which solid particles can be stably dispersed without separating, settling or floating in a substrate even after storage for a long period of time.
It is another object of the present invention to provide a detergent-impregnated article in which dirt is lightly wiped and uneven wiping does not remain after wiping. It is a further object of the present invention to provide a detergent-impregnated article that can easily wipe a large area of dirt.

The following examples illustrate the effectiveness of the detergent impregnated articles of the present invention. However, the present invention is not limited to such an embodiment. In the following examples,%
Means% by weight unless otherwise specified.

Example 1 Formulation of Detergent A detergent was prepared by mixing the following components in the following proportions. <Prescription 1> Silicone resin (solid particles) 3% (average particle size: 3 μm, true specific gravity: 1.3) Dimethyl polysiloxane (protective film forming component) 0.5% n-paraffin (boiling point: 227 ° C.) ) (Cleaning base) 3.5% ・ Dodecyl glucoside (surfactant) 0.50% (Glucose condensation degree 1.35) ・ Thickening polysaccharide (see Table 1) 0.1% ・ Ethanol (drying accelerator) 20% ・ Ion-exchanged water balance <Formulation 2> ・ Silicone resin (solid particles) 6% (average particle size: 3 μm, true specific gravity: 1.3) ・ Dimethylpolysiloxane (protective film forming component) 1% ・ n- Paraffin (boiling point: 227 ° C.) (detergent base) 7% ・ Dodecylglucoside (surfactant) 1.0% (glucose condensation degree 1.35) ・ Thickening polysaccharide (see Table 2) 0.2% ・ Ion Exchange water balance

Production of Cleaning Impregnated Articles Dry type pulp sheet made of Havix having a basis weight of 55 g / m ² and a thickness of 0.9 mm under a load of 0.5 g / cm ² (pulp fibers that have been defibrated and laminated with a binder). (Which were bonded and formed into a sheet) were immersed in the above-mentioned cleaning agent. After the detergent was sufficiently impregnated, the dry pulp sheet was pulled up, and excess detergent was removed using a mangle to obtain a detergent-impregnated article. The amount of the detergent impregnated in the obtained detergent impregnated article was 3 to the weight of the dry pulp sheet.
It was 00-500%. After the obtained detergent-impregnated article was stored horizontally in an airtight container at 40 ° C. for 6 weeks, the cleaning performance of the upper surface of the detergent-impregnated article was examined by the following method. Further, the cleaning performance of the detergent-impregnated article before storage was also examined in the same manner. That is, after leaving the glass for evaluation (flat and transparent soda-lime plate glass which has been sufficiently washed and cleaned beforehand) in a northern place where rainwater does not directly hit, the surface of the glass for evaluation is removed. After wiping with the detergent impregnated article and drying, the surface is kitchen paper (made by Havix,
(Dry pulp sheet). The coefficient of kinetic friction when the surface was wiped dry with the kitchen paper was measured by the following method. In addition, the state of uneven wiping of the surface after wiping with the kitchen paper was evaluated according to the following criteria, and the coefficient of static friction of the surface after wiping was measured by the following method. The results are shown in Tables 1 and 2.

<Measurement of Coefficient of Dynamic Friction> The detergent was uniformly applied (3 g / m ² ) to the surface of the glass for evaluation left under the above conditions for three months by using the detergent impregnated article. After being dried (after about 3 minutes), a kitchen paper (made of Havix, dry pulp sheet) having a diameter of 6 cm was placed, and the kitchen paper was rotated at a speed of 3 under a load of 1.3 kg.
The dynamic friction coefficient was determined by the following equation (1) by measuring the force F applied when the actuator was moved horizontally in cm / sec. If the coefficient of dynamic friction at the time of wiping is 0.4 or more, wiping becomes very heavy and difficult. Dynamic friction coefficient = F (kg weight) /1.3 (kg weight) (1) <Evaluation of uneven wiping> The wiping unevenness reduces the glossiness of the surface to be cleaned due to the occurrence of uneven wiping. The glossiness of the washed surface was measured with a Minolta glossmeter 9M-268.
The unevenness of wiping was evaluated by measuring under the condition of a measurement angle of 85 °. The greater the value of the gloss, the smaller the unevenness in wiping. The unevenness of wiping is visually recognizable when the value is 110 or less. Before leaving (ie, clean surface)
Had a glossiness of 115. <Measurement of static friction coefficient> Static friction coefficient measuring machine (Shinto Kagaku,
HEIDON Tribogear Muse TYPE 94
Kitchen paper (manufactured by Havix, dry pulp sheet) was attached to the measuring section of (i), and the coefficient of static friction of the surface to be washed after washing was measured. Each measurement is the average of n = 5. still,
The static friction coefficient after leaving the glass for evaluation for 3 months under the above conditions was 1.45, and the static friction coefficient before leaving (that is, the clean surface) was 0.52. However, since the coefficient of static friction changes slightly depending on the weather during standing and the surface state of the glass, the above numerical values are a guide.

Example 2 A detergent was prepared according to the following formulation. Thereafter, a detergent-impregnated article was obtained in the same manner as in Example 1. The same measurement and evaluation as in Example 1 were performed on the obtained detergent-impregnated article. Tables 3 and 4 show the results.
Shown in The prescription (4) is a prescription of a comparative product. Formulation (3) Formulation (4) Solid particles (see Tables 3 and 4) 3% 21% Dimethylpolysiloxane (protective film forming component) 0.5% 0.5% n-paraffin (boiling point: 227 ° C.) ) (Detergent base) 2% 2% Dodecylglucoside (surfactant) 0.5% 0.5% (Glucose binding 1.35) Xanthan gum (thickening polysaccharide) 0.15% 0.5%・ Ethanol (drying accelerator) 20% 20% ・ Ion-exchange water Balance Balance

[Table 4]

As is clear from the results shown in Tables 1 to 4, in the detergent-impregnated article of the present invention, a detergent containing a thickening polysaccharide at a specific concentration is used as the detergent to be impregnated on the substrate. This indicates that even after the detergent impregnated article is stored for a long period of time, the solid particles are stabilized in the substrate, and as a result, there is no change in the cleaning performance before and after storage.
Further, the cleaning agent-impregnated article of the present invention can be wiped (dry-wiped).
It can be seen that the coefficient of kinetic friction at the time is small, and that there is no uneven wiping after dry wiping. The coefficient of static friction after dry wiping is determined by the effect of the protective film on the clean surface (0.5%).
It turns out that it becomes smaller than 2).

[0090]

According to the cleaning agent-impregnated article of the present invention, the solid particles can be stably dispersed without separating, settling or floating in the substrate even after long-term storage, thereby impairing the workability during cleaning. And excellent cleaning performance is exhibited. Further, according to the cleaning agent-impregnated article of the present invention, dirt is lightly wiped off, and there is no uneven wiping after the wiping, so that the next cleaning work can be omitted.
Further, according to the cleaning agent-impregnated article of the present invention, a large area of dirt can be easily wiped off.
