Description

The present invention relates to a composition for preventing toilet soiling.

In recent years, with the increasing awareness of cleanliness, the needs for cleaning, stain prevention, deodorization, and deodorization have increased. Among living environments, toilets in particular are prone to dirt and odors, so various cleaning agents, antifouling agents, deodorants, and deodorants have been developed. For example, liquid agents that are dripped onto the toilet surface, gel agents, gel agents, and solid agents that are applied to the toilet surface, pump spray agents and aerosol agents that are sprayed onto the toilet surface, and the top of the toilet tank. There are on-tank formulations (liquid and solid) that are installed in the tank.

For example, as a toilet cleaning agent, a solid agent for toilet cleaning characterized by containing a fluorine-based amphipathic substance (Patent Document 1), a fluorine-based amphiphilic substance, a cationic disinfectant, a phenolic disinfectant , a solid toilet cleaning agent (Patent Document 2) is known, which is characterized in that it contains at least one disinfectant selected from the group consisting of carbanilide disinfectants, pyridine disinfectants, and amine disinfectants. There is.

Furthermore, recently, portable toilets that can be installed in rooms have become widely used in medical settings and care settings for the elderly to reduce the burden of traveling to the toilet. Portable toilets are designed to fill a bucket with water and defecate into the bucket, but if the bucket gets dirty, it can cause a bad odor to spread throughout the room. There is a need for things to become more difficult.

When dirt adheres to the toilet, it takes time and effort to remove it. Additionally, if the toilet remains dirty, a bad odor may occur. In particular, when using resin toilets such as portable toilets, scrubbing the toilet surface with a sponge or scrub brush to remove adhered dirt tends to cause small scratches on the toilet surface, and further dirt adheres to the scratches, making it difficult to remove. There is a problem with becoming. Resin toilets such as portable toilets are more susceptible to dirt than hard toilets such as ceramic ones, so countermeasures are required.

Therefore, the present invention aims to provide a new composition for preventing toilet stains, especially portable toilets.

As a result of extensive studies, the present inventors have discovered that toilet stains can be effectively prevented by using a combination of an alkyl polyglucoside, a cationic surfactant, a fluorine surfactant, and a chelating agent.

The stains that are mainly targeted by the antifouling composition are stains on the interior surface of the toilet, particularly stains on the interior surface of the toilet due to feces. The antifouling composition can prevent the toilet from becoming dirty by suppressing the adhesion of dirt to the inner surface of the toilet.

The type of toilet targeted by the antifouling composition is not particularly limited. The antifouling composition is particularly effective for portable toilets, but can also be used for other types of toilets, such as free-standing toilets.

The material of the toilet (particularly the material of the inner surface) to which the antifouling composition is applied is not particularly limited. The antifouling composition is particularly effective for toilets made of resin, but can also be used for toilets made of other materials such as ceramic, metal, and glass.

The antifouling composition can prevent stains on toilets of various types and materials, but is particularly effective in preventing stains on toilets made of resin. When a resin toilet is repeatedly washed with a sponge or scrubber, the surface of the toilet tends to get fine scratches, and these scratches make it easier for dirt to stick to the toilet. However, by using an antifouling composition, you can prevent dirt from sticking. Can be suppressed. Portable toilets are often made of resin, making them preferred targets for use with antifouling compositions.

The type of resin is not particularly limited, but examples include polypropylene, acrylonitrile-butadiene-styrene (ABS), acrylic, fiber reinforced plastic (FRP), and the like.

<Antifouling method>
One embodiment of the present invention relates to a method for preventing staining of a toilet comprising contacting an interior toilet surface with an antifouling composition. The contact method is not particularly limited, and for example, in the case of a free-standing toilet, the antifouling composition may be added to the water in the toilet, the antifouling composition may be pasted on the inner surface of the toilet, or the antifouling composition may be attached to the top of the toilet tank. Examples include a method of installing an antifouling composition.

In particular, liquid preparations are preferable because the amount used can be adjusted appropriately.

The concentration of the antifouling composition used varies depending on the type of toilet, material, etc., but in the case of a portable toilet made of resin, it is preferably 2000 ppm or more, more preferably 2500 ppm or more. The upper limit of the concentration is not particularly limited, but may be, for example, 15,000 ppm, 50,000 ppm, etc.

Hereinafter, the present invention will be explained in more detail using Examples and Comparative Examples, but the technical scope of the present invention is not limited thereto.

Table 1 shows the raw materials (products) used in the Examples and Comparative Examples. In the Examples and Comparative Examples, the active ingredient contents of the products shown in Table 1 were taken into consideration. The numerical values for each component in Tables 2 and 3 are the amount of the active ingredient, not the blended amount of the product.

<Model stain test on resin surface>
Antifouling compositions were prepared according to the formulations listed in Table 2 (Examples 1 to 10) or Table 3 (Comparative Examples 1 to 16). The antifouling composition was diluted in 160 mL of water to a concentration of 2500 ppm or more. The entire amount of the diluted solution was transferred to a 500 mL plastic cup (made of polypropylene). At this time, the distance from the bottom of the cup to the water surface was set to 2 cm. The temperature of the diluent was approximately 25°C.

Butter (manufactured by Megmilk Snow Brand) as a model stain was shaped into a round shape and sufficiently cooled in a refrigerator at about 10°C. The model dirt was dropped into the diluted solution from a height of 26 cm directly above the water surface in free fall, and the model dirt was collected. The same operation was repeated 5 times.

The diluent was discarded and the cup was air dried. The stain-proofing performance was evaluated by visually observing the model stains on the bottom of the cup after drying. Evaluation was performed on a five-point scale. The evaluation criteria are shown in FIG. 1, and the evaluation results are shown in Tables 2 and 3.

Table 2 shows that the combination of alkyl polyglucoside, cationic surfactant, fluorine surfactant, and chelating agent exhibits excellent antifouling effects on resin surfaces. . On the other hand, Table 3 shows that when at least one of the alkyl polyglucoside, cationic surfactant, fluorine surfactant, and chelating agent is lacking, the antifouling effect is reduced.

<Model stain test on hard surface>
In place of the plastic cup in the model stain test on a resin surface, a glass plate was used as the contact surface for the model stain. Table 4 shows the evaluation results for the following samples (5-level evaluation, evaluation criteria according to FIG. 1).
・Untreated glass plate (sample 1)
・Glass plate treated with the antifouling composition of Example 3 (Sample 2)
・Glass plate treated with the antifouling composition of Comparative Example 5 (Sample 3)

Although the antifouling composition of the present invention is particularly effective on resin surfaces, it was confirmed that it is also effective on hard surfaces.

<Fecal test using portable toilet>
When the antifouling composition of Example 3 was used in a resin portable toilet, the degree of adhesion of human feces was confirmed in a home use test. Even so, it was confirmed that the dirt could be easily removed by rinsing with water without scrubbing with a sponge or scrub brush.
