Description

[Detailed description of the invention]

The present invention relates to aromatic liquid deodorant compositions. More specifically, the present invention is an aromatic liquid deodorant composition containing a specific fragrance and a specific surfactant in an alkaline chlorine dioxide aqueous solution. Conventionally, it has been known that the oxidizing effect of chlorine dioxide can be used to eliminate bad odors that occur in toilets, garbage pits, etc., and Japanese Patent Publication No. 15720/1983 describes the pH of a deodorizing solution containing chlorine dioxide as its main component. A method is described in which the alkalinity of the deodorant is adjusted to 7.5 to 10.5, and a strong alkaline fragrance is added thereto to impart a fragrance to the deodorant. However, the present inventors adjusted a 5% chlorine dioxide aqueous solution to pH 8.5 with sodium hydroxide according to the example described in the above publication, and added 1% fragrance (β-
When a deodorizer was prepared by adding 4% of Pluronik L64 (Asahi Electric Products, polyoxyethylene/polyoxypropylene condensate) as a solubilizer (naphthol ethyl ether), chlorine dioxide decomposed during storage and deodorized. No effect was observed. Note that the above-mentioned publication only discloses β-naphthol ethyl ether in Examples as a specific example of a fragrance resistant to alkali, and does not describe any other fragrances. Therefore, the present inventors conducted intensive research to provide an aromatic liquid deodorant composition in which chlorine dioxide and fragrance do not deteriorate during storage. The present invention was completed based on the knowledge that only when an agent is added, chlorine dioxide and perfume can be stably preserved, and when used, exhibit an oxidizing effect, deodorizing effect and imparting fragrance. That is, the present invention provides an alkaline chlorine dioxide aqueous solution, 2,6-dimethylheptan-2-ol,

The present invention provides an aromatic liquid deodorant composition characterized by containing a surfactant selected from the group consisting of: Further, in the present invention, the chlorine dioxide aqueous solution is 0.001 to 1% by weight as chlorine dioxide, and the fragrance is 0.00005% by weight.
1% by weight and 0.00025 to 5% by weight of the surfactant. Chlorine dioxide used as a deodorizing component in the composition of the present invention is a gas with a strong oxidizing effect and is stable in an alkaline aqueous solution. Therefore, it is usually treated as an aqueous solution of chlorine dioxide with a pH of 7.5 to 10.5, and this aqueous solution is preferably used in the present invention as well. The fragrances used in the present invention to impart fragrances are broadly classified into alcohols, esters, ethers, and others depending on their chemical structures. Flavors that belong to the alcohol category include:
2,6-dimethylheptan-2-ol, tetrahydromguol, tetrahydrolinalool, isobornylmethoxycyclohexanol, o-tertiarybutylcyclohexanol, dimethylbenzylcarbinol, styralyl alcohol, 1
-(2,2,6-trimethylcyclohexyl)-3
-Hexanol, tapineol and benzyl alcohol. Flavors belonging to esters include isobornyl acetate, l-menthyl acetate, tetrahydromugyl acetate, phenylethyl dimethyl carbinyl acetate, cedryl acetate,
Dihydrotapinyl acetate and o-tertiarybutylcyclohexyl acetate are mentioned. Perfumes belonging to the ether class include 1,8-cineole, anisole, p-cresyl methyl ether, beta-naphthol methyl ether, and phenylethyl isoamyl ether.
Other fragrances include camphene, amyl cinnamic aldehyde, methyl amyl ketone, 2,4,6-trimethyl-6-phenyl-
Mention may be made of 1,3-dioxane, p-tertiaryamylcyclohexanone and p-methylacetophenone. The above-mentioned single fragrances are stable in alkaline aqueous solutions and are not oxidized by chlorine dioxide. In general, many alkali-stable fragrances are known, but single fragrances other than those mentioned above are as shown in the comparative examples below.
Even if the chemical structure is similar to the above fragrances, they will be oxidized by chlorine dioxide and lose their fragrance. On the other hand, chlorine dioxide is also decomposed and deactivated, making it no longer effective in deodorizing. In the present invention, the surfactant used to stably dissolve the perfume is also limited to specific anionic surfactants. That is, the surfactants that can be used in the present invention are limited to polyoxyethylene alkyl phenyl sulfate alkali metal salts, polyoxyethylene alkyl sulfate alkali metal salts, and dodecylbenzenesulfonic acid alkali metal salts. Examples of the polyoxyethylene alkyl phenyl sulfate alkali metal salts include polyoxyethylene nonylphenyl sulfate alkali metal salts. Examples of polyoxyethylene alkyl sulfate alkali metal salts include polyoxyethylene lauryl sulfate alkali metal salts. Examples of the alkali metal salts in the surfactant include lithium, potassium, and sodium salts, and sodium salts are usually used. Surfactants other than those mentioned above may not dissolve the perfume sufficiently, or they may themselves be oxidized by chlorine dioxide, causing the chlorine dioxide to lose its activity.
For example, anionic surfactants such as polyoxyethylene alkyl triethanolamine sulfate, sodium lauryl sulfate, triethanolamine lauryl sulfate, sodium polyoxyethylene oleyl ether phosphate, coconut alkanolamide, sodium N-lauroyl sarcosinate, stearyl Cationic surfactants such as methylammonium chloride, alkyldimethylbenzylammonium chloride, and benzalkonium chloride are
Zwitterionic and nonionic surfactants likewise cannot be used as surfactants in the present invention, as they do not dissolve the perfume sufficiently or deactivate the chlorine dioxide. Although the proportion of each component in the composition of the present invention is not particularly limited, the concentration of chlorine dioxide is appropriately selected depending on the type and degree of the malodor to be deodorized, and generally 0.001 to 1% by weight is suitable. be. The concentration of fragrance varies depending on the type, but it is necessary at least to impart a fragrance when using a deodorant.
0.00005% by weight or more is required, generally 0.00005~
1% by weight is suitable. Surfactants are generally used at concentrations necessary to stably dissolve fragrances.
It is 0.00025 to 5% by weight. The composition of the present invention needs to be made into an alkaline aqueous solution in order to store chlorine dioxide stably.
Adjust the pH to 7.5-10.5, preferably 7.5-9.5. The preferred composition of each component of the composition of the present invention is as follows. Ingredients Weight% Chlorine dioxide 0.001~1 Fragrance 0.00005~1 Surfactant 0.00025~5 Water Balance The composition of the present invention is physically and chemically stable, and chlorine dioxide is not deactivated even after long-term storage. Or,
Fragrances will not change in quality. Since the composition of the present invention is an aqueous solution, toilets,
Spray on places where bad odors occur, such as garbage pits and fish containers, or spray directly on the source of bad odors. If necessary, it can also be adsorbed onto a suitable carrier such as talc, pulverized, and sprayed at the source of the bad odor. By applying the composition of the present invention, malodorous substances are oxidized and rendered odorless, and fragrance is imparted by the perfume. Next, the present invention will be explained in more detail with reference to Examples. Example 1 An aromatic liquid deodorant having the following composition was prepared by a conventional method using various single fragrances shown in Table 1. Ingredients Weight % Chlorine dioxide 0.5 Fragrance 0.5 Sodium polyoxyethylene lauryl sulfate 2.8 Water Balance meter 100 As the chlorine dioxide, a 5% aqueous chlorine dioxide solution adjusted to pH 7.5 to 9.5 was used. The above composition was placed in a brown bottle, sealed and stored at 50°C for 14 days, and the residual rate of chlorine dioxide was measured to examine its storage stability. In addition, the aroma stability of each individual fragrance in this composition was determined by sensory evaluation by three panelists. Judgment criteria: ○: No change in aroma is observed. △: Some deterioration of aroma is observed. ×: Deterioration of aroma is observed.
