Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to an aromatic liquid deodorant composition. More specifically, the present invention is an aromatic liquid deodorant composition containing a fragrance and a specific surfactant in an alkaline chlorine dioxide aqueous solution. (Prior art) It has been well known that the oxidizing effect of chlorine dioxide can be used to eliminate bad odors that occur in toilets, garbage pits, etc. A method is described in which the pH of an odor solution is adjusted to an alkaline range of 7.5 to 10.5, and a strong alkaline fragrance is added thereto to impart a fragrance to the deodorant. (Problems to be Solved by the Invention) 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 ( When a deodorant was prepared by adding 4% of Pluronic L64 (Asahi Electric Products, polyoxyethylene/polyoxypropylene condensate) as a solubilizer (β-naphthol ethyl ether), chlorine dioxide decomposed during storage. No deodorizing effect was observed. Incidentally, the above-mentioned publication only discloses β-naphthol ethyl ether as an alkali-resistant fragrance and Pluronic L64 as a fragrance solubilizer in the examples, and does not describe any other fragrances or solubilizers. Therefore, the present inventors conducted extensive research in order 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 the fragrance is dissolved, chlorine dioxide and the fragrance can be stably stored, and when used, exert an oxidizing effect, exhibiting a deodorizing effect and imparting a fragrance. (Means for solving the problems) The present invention provides an alkaline chlorine dioxide aqueous solution,
One or more types of fragrances other than aldehydes, formic acid esters or acetals, or fragrances consisting of amylcinnamic aldehyde, cumin aldehyde, hexylcinnamic aldehyde, or 1,1-diethoxycyclohexane, and α
- a surfactant consisting of an alkali metal salt of olefin sulfonic acid. Further, in the present invention, the chlorine dioxide aqueous solution is 0.001 to 5% by weight as chlorine dioxide, and the fragrance is 0.00005% by weight.
10% by weight and 0.0001 to 25% by weight of the surfactant. In the present invention, all fragrances other than aldehydes, formic acid esters or acetals can be used. As aldehydes, only amyl cinnamic aldehyde, cumin aldehyde and hexyl cinnamic aldehyde can be used. All formic acid esters cannot be used. As the acetal, only 1,1-diethoxycyclohexane can be used. 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. Chlorine dioxide itself is stable in an alkaline aqueous solution, but when fragrances and surfactants are added to it, the fragrances are oxidized and deteriorated, and chlorine dioxide is also decomposed and loses its deodorizing effect. However, when the α-olefin sulfonic acid alkali metal salt of the present invention is used as a surfactant, surprisingly both chlorine dioxide and fragrance are stable, and the purpose of deodorization and fragrance can be achieved. Examples of the alkali metal salt of α-olefin sulfonic acid used in the present invention include alkali metals such as NITSUKOL OS-14 (Nikko Chemicals Co., Ltd.), Soft Detergent 95 (Lion Co., Ltd.), and Riporan 1400 (Lion Co., Ltd.). I can give you salt. Examples of alkali metal salts include lithium, potassium, and sodium salts, and sodium salts are usually preferably used. In the present invention, a wide variety of fragrances that are generally used for the purpose of flavoring can be used. Flavors can be classified into alcohols, esters, lactones, ketones, ethers, oxides, hydrocarbons, aldehydes, and others depending on their chemical structure. Almost any large portion can be used. However, with some exceptions, fragrances having an aldehyde group, a formate group, or an acetal group in their molecules are extremely unstable to chlorine dioxide, and even when the surfactant of the present invention is used, they are oxidized and lose their aroma. Therefore, fragrances having these groups in their molecules cannot be used in the present invention either.
However, amyl cinnamic aldehyde,
Cumin aldehyde, hexylcinnamic aldehyde, and 1,1-diethoxycyclohexane are stable against chlorine dioxide despite having an aldehyde group or an acetal group in the molecule, and therefore can be used as the fragrance of the present invention. I can do it. In the deodorizing composition of the present invention, fragrances can be used alone or in combination of two or more types, and usually, many types of fragrances with different aroma qualities are mixed and used. Although the proportion of each component in the deodorizing composition of the present invention is not critical, 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 5% by weight is suitable. be. The concentration of fragrance is
Although it varies depending on the type, at least 0.00005% by weight or more is required in order to impart a fragrance when using a deodorant, and generally 0.00005 to 10% by weight is appropriate. The concentration of the surfactant may be as long as it is necessary to stably dissolve the fragrance, and is determined appropriately depending on the amount of the fragrance used, but generally the concentration is 0.0001 to 25% by weight. Fragrances and surfactants will not be oxidized by chlorine dioxide as long as they are used within the above concentration ranges, but may become oxidized when used in large quantities beyond the above concentration ranges. In order to store chlorine dioxide stably, the composition of the present invention needs to be made into an alkaline aqueous solution. Adjust to 10.5, preferably 7.5 to 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 Perfume 0.00005-1 Surfactant 0.00025-5 Water Balance (Examples) Next, the present invention will be explained in more detail with reference to Examples.

[Table] Acetate
(Effect of the invention) In the aromatic liquid deodorant composition of the present invention,
By using an alkali metal salt of α-olefin sulfonic acid as a solubilizing agent for perfume, a stable deodorant that does not impair the deodorizing effect of chlorine dioxide can be provided. Chlorine dioxide itself is stable in an alkaline aqueous solution, but when perfumes and their solubilizers are added to this aqueous solution, the perfumes are usually oxidized and deteriorated, and chlorine dioxide is also decomposed and loses its deodorizing effect. Therefore, the fragrances added to deodorants using chlorine dioxide for flavoring purposes are limited to those that are particularly resistant to oxidation. However, if the surfactant of the present invention is used as a fragrance solubilizer, most fragrances can be used without being subject to the above-mentioned limitations.
Therefore, a deodorant having a desired fragrance can be obtained by blending various single fragrances with different fragrance qualities.
