Description

  The present invention relates to a thixotropic composition that does not easily sag when applied to, for example, a wall surface.

  Conventionally, when trying to clean walls to be cleaned such as wall surfaces inside and outside of homes, screens of TVs and personal computer monitors, window glass or screens, and surfaces to be cleaned such as ceiling surfaces, surfactants and A cleaning solution containing a water-soluble solvent or the like is used as it is, or after diluting with water to a predetermined concentration, soaking it in a cloth or a cloth, applying it to the surface to be cleaned, and wiping the applied cleaning solution with dirt. .

  In particular, when the surface to be cleaned has a large area, a method of applying a cleaning liquid to the surface to be cleaned by spraying using a hand trigger spray container and wiping with a cloth or a brush is performed.

  However, in the conventional cleaning method using the hand trigger type spray container as described above, when the cleaning liquid is sprayed on the surface to be cleaned such as the inclined surface, the vertical surface and the ceiling surface of the large area, the target surface to be cleaned is obtained. Since the cleaning liquid does not stay in the part of the liquid, the liquid must be sprayed after a predetermined period of time, or the part that does not want to be cleaned and the part that dislikes moisture or cleaning liquid ( For example, the cleaning liquid may drip on tatami mats, solid wood, and the inside of a TV or a personal computer, which may cause inconvenience.

  As a method for solving such problems, a hand-triggered spray container that does not easily drip after being applied to a surface to be cleaned such as an inclined surface, vertical surface, or ceiling surface by increasing the viscosity of the cleaning liquid. However, since the cleaning liquid is not necessarily sprayed in the form of a mist, it is often sprayed in the form of a rod, and it may scatter to parts other than the surface to be cleaned. It was.

  In addition, various thickening techniques have been proposed as methods for solving such problems. For example, in Patent Document 1 (Utility Model Registration No. 3151806), Patent Document 2 (Japanese Patent Laid-Open No. 11-263998) and Patent Document 3 (Japanese Patent Laid-Open No. 2001-172688), a sepiolite type is used as an inorganic thickener. By adding clay minerals, the cleaning agent has thixotropic properties (thixotropic properties), and is sprayed with a commercially available hand-triggered spray container. There has been proposed a method of applying the resin accurately.

Utility Model Registration No. 3151806 JP-A-11-263998 JP 2001-172688 A

  However, in the detergent proposed in the above patent document, in order to impart thixotropic properties, it is 2 to 3% by weight (Patent Document 1: Utility Model Registration No. 3151806), 1 to 10% by weight (above Patent Document 2: JP-A-11-263998) or 0.1-10 wt% (preferably 1-5 wt%)% (above Patent Document 3: JP2001-172688) thickens It has been proposed to add as an agent, and in any case, the amount of inorganic mineral added is large.

  As described above, the conventional cleaning agent uses a large amount of a thickening agent made of an inorganic mineral that does not dissolve in water, so it is costly. When the cleaning agent is wiped after being applied to the surface to be cleaned, the wiping is performed. If it is not performed completely, the inorganic mineral will remain attached to the surface to be cleaned after drying, and wiping (dirt) is likely to occur. For example, when used for cleaning such as a bathroom floor, System minerals may remain and become slippery.

  In addition, when a conventional cleaning agent is used for cleaning, for example, carpets and stuffed animals with long hairs, even after wiping with a wet towel, the inorganic mineral remains as dust after drying and is uncomfortable. There is.

  Accordingly, an object of the present invention is to solve the problems of conventional cleaning agents having thixotropic properties by including a thickener composed of inorganic minerals as described above, such as inclined surfaces, vertical surfaces, and ceiling surfaces. Wipe away without dripping on the coated part of the surface to be cleaned, allowing the cleaning agent to fully exert its original effect, and adding a small amount of thickener to impart thixotropic properties. It is an object of the present invention to provide a cleaning agent in which the remainder and problems caused by this (stain, slip, long rinsing time, etc.) are unlikely to occur.

  In order to solve the above problems, the present inventors have repeated intensive experiments using various materials, and as a result, the present invention stays without dripping in the coated portion of the surface to be cleaned, and the original effect of the active ingredient is sufficiently obtained. In order to obtain a cleaning agent that can be exerted on the surface and has a small addition amount of a thickening agent for imparting thixotropic properties and is less likely to cause wiping residue and problems due thereto, It has been found that the use of a thixotropic agent containing a polymeric polysaccharide, water, and water-soluble salts is effective. Further, in particular, the present inventors have found that the thixotropic composition of the present invention can be suitably used as a cleaning agent, a repellent, a feed or the like, and completed the present invention.

That is, the present invention
A thixotropic agent containing a natural polymeric polysaccharide derived from glucose;
water and,
Water-soluble salts,
Cleaning ingredients, repellent ingredients or nutrients;
Containing at least,
There is provided a thixotropic composition containing a spraying device (hereinafter, also simply referred to as “thixotropic composition”) characterized by being filled in the spraying device.

  The thixotropic composition of the present invention is characterized by a so-called organic system comprising a natural polymeric polysaccharide derived from glucose, unlike the above-described conventional technique in which a thickener composed of an inorganic mineral is used as a thixotropic agent. The thixotropic imparting agent, water-soluble salts, and water are included. Conventionally, such a glucose-derived natural polymer polysaccharide has never been used as a cleaning agent or the like, but as a result of repeated studies by the present inventors, the glucose-derived natural polymer polysaccharide has been used as a cleaning agent. It has been found that it can be used as a repellent or feed and is effective for solving the above-mentioned problems, and the present invention has been completed.

  Since the thixotropic composition of the present invention uses an organic thixotropic agent, the thixotropic composition stays without dripping on the coated portion of the surface to be cleaned such as an inclined surface, a vertical surface and a ceiling surface. Other active ingredients (for example, cleaning ingredients, repellent ingredients or nutrients) can fully exert their original effects, and the addition amount of a thickening agent for imparting thixotropic properties is small. There is a remarkable effect that problems due to this (stain, slip, long rinse time, etc.) do not occur. In the case of repellents containing repellent ingredients, it is possible to kill insects with repellents while capturing mosquitoes and cockroaches with foam and thixotropic properties. It is suitable for capturing insects such as beetles and stag beetles because they are continuously attached to the site. In the latter case, there is an advantage that the thixotropic agent is not harmful to these insects.

As "thixotropic agent containing natural polymer polysaccharides derived glucose" as used in the present invention, mentioned as typical, for example gellan gum, a etc. microbial fermentation system thickening agent such as welan gum and xanthan gum be able to. The gellan gum may be a deacyl type on the upper side of the following formula or a native form on the lower side of the following formula.

  Examples of gellan gum include “Kelcogel” (trade name) manufactured by Kelco, USA. Examples of xanthan gum include “Kelzan” (trade name) manufactured by Kelco, USA. Among these, the kelcogel is approved by the FDA in the United States, and is also approved as a food additive in Japan, and is characterized by high safety to the human body. Since the thixotropic composition of the present invention is used inside and outside the home, it may accidentally get into the mouth and eyes, but when using such a thixotropic agent comprising the above kelcogel, From the viewpoint of safety, it is more preferable.

In addition, the thixotropic composition of the present invention described above,

100 to 10,000 ppm of the water-soluble salts,
0.1 to 35% by weight of the cleaning ingredient, 0.1 to 20% by weight of the repellent ingredient or 0.1 to 50% by weight of the nutrient,
It is preferable that the balance is water.

  The thixotropic composition of the present invention having such a structure retains without foaming and dripping on the coated portion of the surface to be cleaned even if the amount of the thixotropic agent is small compared to the conventional one. Thus, the original effect of the cleaning component can be sufficiently exerted, and no wiping residue and problems caused by this (stain, slip, long rinse time, etc.) do not occur.

  The thixotropic composition of the present invention contains a cleaning component (for example, 0.1 to 35% by weight) when used as a cleaning agent. In this case, it is preferable to further contain a cleaning auxiliary component. The content of this cleaning auxiliary component may be, for example, 0.1 to 10% by weight.

  Moreover, the thixotropic composition of the present invention contains a repellent component when used as a repellent and contains a nutrient when used as a feed. What is necessary is just to adjust these content suitably in the range which does not impair the effect of this invention.

  According to the present invention, the other active ingredients (for example, cleaning ingredients, repellent ingredients, nutrients, etc.) that remain without dripping onto the application portion of the surface to be cleaned such as the inclined surface, vertical surface, and ceiling surface due to foaming. The amount of thickener added to impart thixotropic properties is small, causing wiping residue and problems (stains, slips, long rinse times, etc.) resulting from this. A thixotropic composition that is difficult to achieve can be realized.
