[Detailed description of the invention]

INDUSTRIAL FIELD OF APPLICATION The present invention relates to a cleaning fragrance composition, and more particularly to a gel-like cleaning fragrance composition that is used in contact with water during flushing of a flushing toilet. BACKGROUND ART In recent years, with the improvement of living standards, the development of sewage systems and the use of flush toilets have progressed, and the popularity of water storage type flush toilets has continued to expand. Under these circumstances, the installation of toilet air fresheners and the use of in-tank toilet cleaners are becoming more widespread as a means to keep toilets bright, fresh, and sanitary. However, it is difficult to use both the above-mentioned air freshener and in-tank toilet cleaner at the same time due to space constraints.
This is economically disadvantageous, and the current situation is that there is a strong desire to develop a product that has both the functions of an air freshener and a toilet cleaner. However, the above-mentioned aromatic agents are originally capable of scenting a space when they come into contact with air, while cleaning agents are dissolved in water and have the effect of cleaning toilet bowls and other areas when they come into contact with water. Essentially, their usage forms and functions are different, and each is adjusted separately according to the above, and when simply combined, both functions, ie, the function of gradually dissolving and producing the desired cleaning effect. It is impossible to volatilize into the air and simultaneously and sufficiently create an aromatic atmosphere. Problems to be Solved by the Invention The present invention aims to provide a new cleaning fragrance product that has the functions of both the above-mentioned fragrance and toilet cleaning agent, which are strongly desired in the industry. . Means for solving the problem The above purpose is to (a) 12-hydroxystearic acid 1
-8% by weight and/or 0.1-5% by weight of benzylidene sorbitol, (b) 20-70% by weight of fragrance, (c) 10-30% by weight of pigment, and (d) 15-60% by weight of surfactant. The present invention relates to a gel-like cleaning/fragrance composition which is used by being brought into contact with water by flushing. The gel-like cleaning aromatic composition for water storage type flush toilets of the present invention contains a predetermined amount of the above-mentioned specific components. During the flushing process, the cleaning agent components are eluted at a certain concentration into a certain amount of water, and this produces a cleaning effect. Therefore, the purpose of space fragrance can be effectively achieved. What is truly surprising is that even after repeated flushing, the composition itself does not swell, disintegrate, or flow out, and furthermore, the volatility of the fragrance is not inhibited at all. It can sustainably produce a sufficient aroma as a fragrance. In particular, the composition of the present invention is stable even when the perfume content is increased, and therefore the purpose of providing spatial perfuming can be achieved more effectively. In addition, the composition of the present invention is used by being installed in a hand-washing area, etc., as described above, and is easy to use, such as by lifting a heavy ceramic lid and installing it, as seen in in-tank cleaners. It has the advantage of not requiring any effort. In the present invention, 12-hydroxystearic acid and/or benzylidene sorbitol are used as the first
Used as an essential component of Among the above, benzylidene sorbitol is a condensation reaction product of sorbitol and benzaldehyde, and depending on the molar ratio of raw materials and reaction conditions, monobenzylidene sorbitol,
Dibenzylidene sorbitol and tribenzylidene sorbitol are produced, and both have substantially the same effect and can be used alone or as a mixture. The above 12-hydroxystearic acid is 1 to 8% by weight, preferably 2 to 6% by weight in the total composition.
It is important that benzylidene sorbitol is incorporated in the total composition in an amount of 0.1 to 5% by weight, preferably 0.5 to 2% by weight. If these are below the above ranges, solidification properties may be poor, heat resistance may be reduced, flow may occur due to temperature rise, and the persistence of flushing and perfume volatilization may be reduced. Further, even if the amount exceeds the above range, the desired effect will not be improved proportionally, which is economically undesirable, and furthermore, insoluble matter will be produced during formulation, making it difficult to prepare a uniform formulation. In the present invention, as the second component fragrance, various fragrances conventionally used as fragrances can be used singly or in combination of two or more. Specific examples include natural plant essential oils such as lavender, lemon oil, rose oil, spearmint oil, and green oil; animal fragrances such as musk and cypet; synthetic fragrances such as aldehydes, ketones, and esters. Examples include mixtures of the like. The amount of the above-mentioned fragrance added to the composition of the present invention varies slightly depending on the type of fragrance, the intensity of the fragrance, etc., but it is usually preferably in the range of 20 to 70% by weight. When the blending amount of the above fragrance is less than 20% by weight, the fragrance is too weak. When blending in a large amount exceeding 70% by weight, it becomes difficult for the composition to solidify at room temperature, the robustness of the composition itself decreases, and it is easily eluted by running water, making it impossible to increase the number of times of flushing. . A particularly preferred amount of fragrance is approximately 30~
It is said to be 60% by weight. The dye used as the third component in the present invention is a measure of the effectiveness of the gel-like cleaning/fragrance composition itself of the present invention, and examples of the dye include water-soluble dyes such as methylene blue, cyanine blue, and blue. No. 1, Yellow No. 4, Yellow No. 5, Green No. 3, Blue 202
No., blue No. 203, etc. can be used to advantage. The blending ratio can be appropriately determined depending on the type of pigment (color tone, density), but it is usually appropriate to set it at about 10 to 30% by weight based on the total composition. If this is less than 10% by weight, the color of the eluate may be pale or may not be colored at all, and the refreshing and hygienic feeling may not be expressed.
If it exceeds % by weight, the coloration will be too dark and will give a rather unpleasant feeling. The surfactant, which is the fourth component in the present invention, mainly contributes to detergency, and also affects the slow solubility of pigments and fragrances and the fastness of the composition. Particularly for fragrances, it is possible to elute them simultaneously with running water, and as a result, expand the volatilization area of the fragrances. As the above-mentioned surfactant, various widely known surfactants can be used. Typical examples include polyoxyethylene lauryl ether, polyoxyethylene cetyl ether, polyoxyethylene oleyl ether, polyoxyethylene nonylphenol ether, polyoxyethylene sorbita tristearate, polyoxyethylene sorbitan monostearate, polyethylene glycol Examples include monostearate, polyethylene glycol distearate, polyoxyethylene distearate, and oxyethylene oxyproprene block polymer. These may be used alone or in combination of two or more. Among these, polyoxyethylene distearate, polyoxyethylene nonylphenol ether, polyoxyethylene lauryl ether, etc. are particularly preferred. The above surfactant is present in the entire composition.
The desired effect can be achieved by blending in an amount of 15 to 60% by weight, preferably 20 to 55% by weight. If this is less than 15% by weight, foaming properties will be poor;
No cleaning effect can be expected, and slow solubilization of the dye becomes difficult, which may lead to a decrease in the fastness of the composition. If it exceeds 60% by weight, the content of other components, especially fragrances, will inevitably decrease, resulting in a decrease in aromatic properties. The composition of the present invention may further contain additives such as known disinfectants, disinfectants, dechlorinators, etc., if necessary. The composition of the present invention is usually prepared as follows, shaped into an appropriate dosage form, and put into practical use. That is, after each component is heated and melted and mixed, the mixture is poured into a mold of an arbitrary shape and cooled to form a solid gel-like cleaning fragrance product for water storage type flush toilets. More specifically, first, predetermined amounts of surfactant, 12-hydroxystearic acid, and/or benzylidene sorbitol are heated and melted, and predetermined amounts of fragrance, coloring matter, and other additives as necessary are mixed with this. However, a method of pouring this mixture into a mold and cooling it can be advantageously employed. The dosage form of the product is appropriately determined depending on the form of use of the product, but it is usually in the form of a solid block placed in a container of an appropriate size, such as a dish-shaped container, and may also be in the form of pellets, rods, or tablets. etc. The above-mentioned product can be put into practical use, for example, by being housed in a device having suitable water holes and drainage holes and installed in a hand-washing section of a water storage tank. Further, the above-mentioned product may be packaged with a water-permeable breathable sheet such as a non-woven fabric and placed in the above-mentioned hand-washing area or the like. The size of the above product is also arbitrary and is appropriately determined depending on its surface area (area in contact with water), period of use, etc.
15g can be used for about a month. EXAMPLES The present invention will be explained in detail below using Examples and Experimental Examples. Examples 1 to 27 Each component (total amount 15
