Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning composition, and particularly to a cleaning composition that exhibits a toilet bowl cleaning effect.

Up until now, aromatic cleaning agents have been developed that use a combination of paradichlorobenzene and detergent, but when this aromatic cleaning agent is used in flush toilets, the detergent is quickly distilled off during flushing, and the paradichlorobenzene is removed. There were problems such as the powder coming off from the molded product.

In addition, this detergent has a strong aroma peculiar to paradichlorobenzene, and has the disadvantage that even if fragrance is added to this detergent, the fragrance will be drowned out. The present inventors have discovered that when used in a toilet bowl, the necessary amount of detergent dissolves during flushing, exhibiting sufficient cleaning power, and that water-insoluble substances are not detached from the molded product. As a result of research to develop a detergent composition, it was discovered that the desired cleaning composition could be obtained by blending a surfactant, which is a detergent component, with a specific carrier. In the course of this research, it was also discovered that the above-described surfactant and carrier formulations were capable of retaining perfumes and/or dyes in large amounts and over long periods of time. The present invention has been made based on these findings. The present invention provides a cleaning composition comprising 20 to 90 parts by weight of a carrier comprising adamantane and endotrimethylenenorbornane and 80 to 10 parts by weight of a surfactant.

Adamantane (hereinafter abbreviated as AD).

) is a non-toxic, odorless, sublimable hydrocarbon that is insoluble in water, and has a high melting point (268°C), so even when mixed with other crystalline hydrocarbons, the melting point does not drop sharply. Therefore, it can be easily mixed and molded with other sublimable hydrocarbons. In addition, it has good shape retention after molding, and if mixed with other sublimable hydrocarbons,
The mechanical strength of the molded article can be increased. Endotrimethylene norbornane (hereinafter abbreviated as TMN).

) is a sublimable hydrocarbon, and in the present invention, it is used together with AD as a carrier for the surfactant. The surfactant used in the present invention must be solid at room temperature and must be stable when mixed with the carrier and upon heating (up to about 180° C.).

More desirably, it is a substance that does not attract moisture in the air and does not deliquesce, and that it does not foam when mixed with a carrier or heated. Suitable surfactants include anionic surfactants and nonionic surfactants, and specific examples of the former include carboxylic acid salts such as sodium stearate, and sulfuric acid esters such as sodium hexadecylsulfonate. , sodium dodecylbenzenesulfonate, di(2)
-ethylhexyl) sodium sulfosuccinate, and the latter include fatty acid monoglycerides such as stearic acid monoglyceride, and zorbitan fatty acid esters such as zorbitan laurate. Among these, sulfonate salts are particularly preferred. Carrier (AD
．． The amount of the carrier (AD.TMN) and surfactant is usually 2 parts by weight per 100 parts by weight of the total amount of both.
0 parts by weight or more, 20 to 90 parts by weight, preferably 40 to 9 parts by weight
0 parts by weight, 80 parts by weight or less of surfactant, 80 to 10 parts by weight, preferably 60 to 10 parts by weight.

Furthermore, the carriers AD and TMN can be used in any ratio, but preferably AD:TMN-1:1 to
20 (weight ratio), more preferably 1:2 to 5 (weight ratio). The cleaning composition of the present invention can be obtained by heating and melting the carrier and the surfactant, cooling and solidifying (molding if necessary) the mixture. Incidentally, fragrances and dyes may be added to the cleaning composition of the present invention if desired, but in this case, the carrier (AD.
After heating and melting TMN) and surfactant, before cooling and solidifying, 0.1 to 20 parts by weight for perfumes and 0.005 to 10 parts by weight for dyes per 100 parts by weight of the total amount of carrier and surfactant. Just add parts by weight.

There are no restrictions on the fragrances and dyes that can be used in the present invention, and they may be selected as appropriate. Flavors used in the present invention include α-ionone, borneol, gunfer, linalool, geraniol, citronellol, citronellal,
Terpene fragrances such as citral, linalyl acetate, and terpineol; aromatic fragrances such as coumarin, neroline, diphenyl oxide, β-phenethyl alcohol, acetophenone, and benzyl alcohol; aliphatic fragrances such as alcohol, aldehyde, and lactone; etc. In addition to synthetic fragrances, there are also animal fragrances such as ziyako and chinensis, and vegetable fragrances such as peppermint oil and lavender oil.

Although it is most preferred to use crystalline perfumes alone, liquid perfumes may also be used and are usually used in mixtures. Further, as the dye, water-soluble dyes such as methylene blue, orange, Congo Red, Alizan Red S, etc. are preferable. TMN, which is a sublimable carrier, is a sticky crystal and has low hygroscopicity, so when it is mixed with a surfactant and made into a molded product, it prevents water from penetrating into the interior of the molded product when washed with water. , it is possible to adjust the amount of surfactant dissolved. Moreover, since AD is also used as a carrier along with TMN, it is possible to retain a larger amount of components such as surfactants, fragrances, and dyes, and to obtain molded products with excellent shape retention and high mechanical strength after molding. I can do it. Furthermore, AD has the effect of suppressing weight loss of the entire molded product due to sublimation, and is effective for sustaining the desired effect. In addition, when the cleaning composition of the present invention is exposed to air other than when washing with water, the sublimable carriers AD and TMN sublimate, constantly exposing new surfactant to the surface and ensuring sufficient water for the next washing. It is possible to demonstrate cleaning power.

In this case, if the cleaning composition contains fragrance, AD
As the fragrance and TMN sublimate, the fragrance also evaporates moderately.
Create a comfortable environment with a pleasant fragrance in the room. Further, by adding a dye, the appearance of the molded cleaning composition can be made beautiful, and since a portion of the composition is dissolved when washed with water, it is possible to color the water and give a clean feel when using the composition. In the cleaning composition of the present invention, the cleaning effect and period of use of the cleaning composition can be arbitrarily set by appropriately selecting the blending ratio of the sublimable carrier and the surfactant. Further, the composition of the present invention can retain a relatively large amount of perfume and dye, and has an excellent retention rate of these substances, so that the desired effect can be maintained for a long period of time.
Furthermore, since the composition of the present invention does not cause water-insoluble substances to be detached from the molded article during washing with water, the disadvantages experienced in the past in use can be overcome. Further, when a fragrance is added to the composition of the present invention, the fragrance is not impaired by the carrier. Next, the present invention will be explained in detail with reference to examples. Example 1 12 parts by weight of AD, 48 parts by weight of TMN and 40 parts by weight of sodium dodecylbenzenesulfonate were heated.
After melting and mixing uniformly, it is poured into a shear plate (diameter 90 mm).
7! Lm, height 15 mm), cooled and solidified.

The molded product (weighing approximately 18 f) placed in this shear dish was sublimated in an air stream at room temperature, and the weight change of the entire molded product was measured.

Next, the molded product produced in exactly the same manner as above was sublimated in an air stream at room temperature for 2 days, then immersed in a container (diameter 450 mm) containing 51 water, and dissolved in water under natural convection. Removed those that do.

After 24 hours, the molded product was taken out of the water, thoroughly drained, and sublimated in air again for 3 days.

Thereafter, the procedure of immersing it in water for 24 hours and sublimating it for 3 days was repeated two more times. The weight change at this time was measured.
The results obtained are shown in FIG. As is clear from the figure, the weight of the molded product that is not submerged in water gradually decreases due to sublimation, and even after repeating the submergence process three times, the remaining amount of the molded product is relatively large. The effect can be maintained for a long period of time.

Example 2 After adding 10 parts by weight of fragrance to a heated melt of 12 parts by weight of AD, 48 parts by weight of TMN, and 40 parts by weight of sodium dodecylbenzenesulfonate, this was poured into a chalet (diameter 90 mu, height 15 mm), cooled, and solidified. I let it happen.

The molded product (weighing approximately 187 cm) placed in this shear dish was sublimated in an air stream at room temperature, and the weight change of the entire molded product was measured.

On the other hand, a molded article produced in exactly the same manner as above was immersed in a container (diameter: 450 m, 7 nm) containing 51 water, and water-soluble materials were removed.

After 24 hours, the molded product was taken out of the water, thoroughly drained, and then sublimated in an air stream to determine the weight change of the entire molded product.

The weight composition of the fragrance used in this example was 40 parts of benzyl acetate, 40 parts of linalool, and 20 parts of limonene.
It was hot at the club. The results are shown in Figure 2. As is clear from the figure, the weight of the molded product does not significantly decrease due to the submersion treatment.

Further, even if a large amount of fragrance is added, the resistance of the molded product to water does not decrease much. Example 3 A heated melt of 16 parts by weight of AD, 64 parts by weight of TMN and 20 parts by weight of sodium dodecylbenzenesulfonate was prepared, and the following procedure was carried out in exactly the same manner as in Example 2.

The results are shown in Figure 3. As is clear from the figure, by increasing the amount of carrier added, there is almost no difference between the submerged molded product and the untreated molded product.

The perfume is considered to be dissolved in the sublimable carrier, and in this case the retention period of the perfume is further extended. Example 4 5 parts by weight of fragrance (same composition as in Example 2) was added to a heated melt of 18 parts by weight of AD, 42 parts by weight of TMN and 40 parts by weight of sodium dodecylbenzenesulfonate, and the following operation was carried out in exactly the same manner as in Example 2. .

The results are shown in Figure 4. Example 5 15 parts by weight of AD, 35 parts by weight of TMN, and 50 parts by weight of sodium dodecylbenzenesulfonate were blended, and the following operation was carried out in exactly the same manner as in Example 4.

The results are shown in Figure 5. As is clear from FIGS. 4 and 5, when the amount of surfactant added is increased, the weight change of the molded product in the air stream becomes less noticeable.

However, when submerged in water, the weight of the molded product changes considerably.
