Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a detergent composition having a deodorizing effect and a high detergency.

[0002]

2. Description of the Related Art A wall in a living room or toilet in a house,
A cleaning agent is used to remove dirt adhering to floors, shelves, toilet bowls, and the like. On the other hand, in recent years, many people are interested in preventing the smell of cigarettes and pets in the living room and the odor of feces and urine in the toilet.

Therefore, conventionally, in a living room or a toilet in a house, a cleaning agent for removing dirt adhering to walls, floors, shelves, toilet bowls, etc., and, apart from that, an odor remaining in the house or toilet. A deodorant or deodorant for masking or removing was used. These deodorants or deodorants are of a type that is used by spraying when necessary with an aerosol or the like, and deodorant components are always volatilized when placed on a shelf or the like.
Or, there is a type that absorbs odorous components, but either type is often placed on a place such as a shelf or floor where it can be seen. Also, the cleaning agents and deodorant deodorants used in the toilet are
In addition to cleaning agents and deodorizing deodorants used to remove dirt and remove odors in the living room, they are often dedicated to toilets and often have tools such as brushes.

However, when a large number of products are placed in a narrow space in this way, it not only occupies a space, but also gives a messy impression to the appearance, which is a problem especially in the toilet.

Therefore, a multifunctional composition having both a deodorizing effect and a detergency effect is desired, but a composition of a detergent having a sufficient deodorizing effect and a high detergency by simply blending the both. I can't get anything.

[0017]

The cleaning composition of the present invention has both an excellent cleaning effect and a sufficient deodorizing effect. Therefore, it is possible to remove and wash dirt and deodorize the odors of cigarettes, pets and stools floating in the space. Further, the cleaning composition of the present invention can prevent redeposition of stains.

[0018]

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples.

Examples 1 to 12 and Comparative Examples 1 and 2 A detergent composition having the composition shown in Table 3 was prepared, and its detergency and deodorizing effect were evaluated by the following methods. The results are shown in Table 3.

(Detergency test) As a model of organic dirt, tempura oil was uniformly applied to an iron plate and baked at a temperature of 180 ° C. for 20 minutes to form an almost dry film to form a model-contaminated plate, which was used. A detergency test was performed. Further, as a model of inorganic stain, a 10% calcium phosphate solution was uniformly applied to a black tile and dried to prepare a model-contaminated plate, and a detergency test was conducted using this.

In the detergency test, the detergent composition was dropped on the above model contaminated plate fixed horizontally and allowed to stand for 40 seconds.
The floating dirt was lightly removed with absorbent cotton, and the degree of cleaning (cleaning power) was visually measured. The values in the table are the% stain removal as an average value of five model contaminated plates.

(Difficulty in Staining in Practical Use) Using a real toilet bowl, the difficulty in getting a stain was evaluated. That is, the toilet bowl was washed with the detergent composition, and the stain resistance when left standing for 1 week was measured with the naked eye. The evaluation criteria are as follows.

[0023]

[Table 1]

(Method of measuring deodorant effect) 1 ml of the cleaning composition was dropped into a 6-liter wide-mouthed bottle containing a cigarette odor or a stool odor, and the deodorant effect at that time was evaluated by sensory evaluation by 10 panelists. It evaluated according to the following evaluation criteria.

[0025]

[Table 2] Good: Deodorizing effect. Δ: There is a slight deodorizing effect. X: Almost no deodorizing effect.

[0026]

[Table 3]

From the above results, Examples 1 to 12 of the present invention
It can be seen that the composition (1) is excellent in detergency, deodorizing effect and stain resistance. On the other hand, it is understood that Comparative Examples 1 and 2 are not sufficient in any of these effects. In addition, Examples 1 to 5 showed the relationship between the amount of the surfactant and the performance, and all showed good cleaning effect and deodorizing effect. In particular, the surfactant amount of 1 to 20% by weight was excellent.
