Description

[Technical Field]

[0001] SUMMARY The present disclosure relates to surface treatment compositions for use on articles having hard surfaces, and methods for treating hard surfaces. [Background technology]

[0002] Cleaning is one of the main household chores, and the act of cleaning places a great burden on the worker not only physically but also mentally.

[0003] Stress from housework is directly linked to whether one likes or dislikes the task. If the mental stress causes one to dislike cleaning itself, the mental stress caused by cleaning may increase.

[0004] The relaxing effect of fragrance can be cited as a method for relieving mental stress. For example, methods have been proposed for improving the persistence of fragrance on the surface of clothing fibers in laundry detergents or fabric softeners (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6716200 [Patent Document 2] Patent No. 4879654 [Patent Document 3] Japanese Patent Application Laid-Open No. 2007-16161 Summary of the Invention [Problem to be solved by the invention]

[0006] As described above, methods are known for laundry detergents or fabric softeners that improve the persistence of fragrance on the surface of clothing fibers, and are expected to have the effect of easing the mental stress of laundry workers in addition to wearing the clothes.

[0007] On the other hand, cleaning also involves wiping hard surfaces such as furniture, bathtubs, toilets, and windowpanes. Unlike fibrous surfaces, hard surfaces are flat. Therefore, fragrance components do not easily remain on hard surfaces, and it is not possible to expect the fragrance to remain on hard surfaces using the above-mentioned techniques.

[0008] Many hard surface cleaners are scented with fragrances, but these fragrances are mainly used to mask the distinctive odors of the surfactants and other raw materials contained in the cleaners, and the scent cannot be expected to last on hard surfaces.

[0009] Furthermore, hard surface cleaners contain a large amount of surfactants to remove dirt. Therefore, the fragrance ingredients are quickly removed along with the surfactants by rinsing, wiping, etc. Therefore, the effect of fragrances in hard surface cleaners in easing the mental stress of workers is only immediate.

[0010] The present inventors attempted to develop a surface treatment agent that contains a surfactant but leaves a scent on hard surfaces for a long time after rinsing or wiping.

[0011] For example, aldehyde-based fragrances are used in hard surface cleaners with excellent fragrance retention. For example, Patent Document 3 describes that alcohol-based fragrances and hydrocarbon-based fragrances have weak fragrances and short retention times, but aldehyde-based fragrances are superior in this respect. This is because the fragrance of aldehyde-based fragrances is strong, making it easy to sense the scent lingering in the air. On the other hand, if the aldehyde-based fragrance is contained in a high concentration, the lingering scent is often perceived as an unpleasant odor, and there is a concern that the lingering scent may actually cause stress for some people.

[0012] Therefore, the inventors focused on α-pinene, a hydrocarbon fragrance that is found in large amounts in conifers and is known to have a strong soothing effect, and conducted extensive research into technology that would increase the persistence of fragrances from hard surfaces (especially fragrances derived from α-pinene) when attached to hard surfaces by using it to wipe hard surfaces, etc.

[0013] The primary object of the present disclosure is to provide a surface treatment composition that, when applied to the hard surface of an article, provides excellent fragrance retention from the hard surface. Another object of the present disclosure is to provide a hard surface treatment method using the surface treatment composition. [Means for solving the problem]

[0014] The inventors of the present disclosure conducted extensive research to solve the above-mentioned problems, and as a result, found that by blending a surface treatment composition to be used on an article having a hard surface, which contains a betaine-based amphoteric surfactant, α-pinene, and an essential oil extracted from at least one plant selected from the group consisting of Lamiaceae, Pinaceae, Cupressaceae, Myrtaceae, and Rutaceae, and a polysaccharide in predetermined ranges, when the surface treatment composition is applied to the hard surface of an article, a surface treatment composition can be obtained which has excellent fragrance longevity from the hard surface, despite containing α-pinene, a hydrocarbon fragrance component which is generally considered to have poor fragrance longevity.

Item 2. The surface treatment composition according to Item 1, wherein the betaine-based amphoteric surfactant as component (a) comprises at least one selected from the group consisting of lauryl dimethylaminoacetic acid betaine, coconut oil alkyl betaine, stearyl dimethylaminoacetic acid betaine, lauric acid amidopropyl betaine, coconut oil fatty acid amidopropyl betaine, palm kernel oil fatty acid amidopropyl betaine, lauryl hydroxysulfobetaine, lauramidopropyl hydroxysultaine, coconut oil fatty acid dimethylaminohydroxysulfobetaine, and lauryl dimethylaminohydroxysulfobetaine.

Item 4. The surface treatment composition according to any one of Items 1 to 3, wherein the fragrance lasts under the following conditions: (Conditions) The surface treatment composition was sprayed as foam (approximately 1 g) into a 1 L beaker, covered with commercially available polyvinylidene chloride plastic wrap, and left sealed for 5 minutes at 25°C and 50% RH.

[0062] In Table 1, Kita Sawmill, FLORIHANA, Kao, and Shin-Etsu Chemical are manufacturers, while Kaorito LLC and LC Kaori Cafe are distributors. Kaorito's fir essential oil and tea tree essential oil were purchased through the Kaorito LLC website (https: / / kaorito.shop), respectively. LC Kaori Cafe's lemon essential oil, yuzu essential oil, and orange essential oil were purchased through the LC Kaori Cafe website (https: / / lifecomfort.biz / ).

[0063] [Preparation of surface treatment composition] Examples 1 to 6 and Comparative Examples 1 to 7 The surface treatment compositions of Examples 1 to 6 and Comparative Examples 1 to 7 were prepared by mixing the components so as to obtain the compositions (total 100 mass%) shown in Tables 2 and 3. In the compositions of Tables 2 and 3, the numerical values ​​of each component are effective mass%.

[0064] <Evaluation of fragrance retention from hard surfaces> Each surface treatment composition obtained in the Examples and Comparative Examples was used as an evaluation sample. Each sample (approximately 1 g) was sprayed into a 1-L beaker, covered with commercially available polyvinylidene chloride wrap, and allowed to stand for 5 minutes at 25°C and 50% RH. After 5 minutes, the beaker was rinsed three times with 30 mL of tap water to confirm that all the bubbles had disappeared. The scent was then confirmed, and the beaker was immediately re-covered with the same wrap and allowed to stand for 1 hour at 25°C and 50% RH. Next, the lid was opened, and five panelists each confirmed the scent inside the beaker. If all five panelists confirmed that the scent remained the same as the scent detected before the 1-hour stand, the sample was evaluated as having high scent persistence from the hard surface (passed "◯"). If even one of the five panelists did not confirm that the scent remained the same as before the stand, the sample was evaluated as having poor scent persistence from the hard surface (failed "X").

[0065] <Evaluation of pleasantness or unpleasantness of scents from hard surfaces> If any residual fragrance was detected using the method described above, the remaining fragrance was evaluated as pleasant or unpleasant. If all five panelists perceived the fragrance as pleasant, it was rated as "pleasant." If even one panelist did not perceive the fragrance as pleasant, it was rated as "unpleasant." However, if the fragrance was already perceived as unpleasant when checked before leaving it for one hour, it was also rated as "unpleasant." The results are shown in Tables 2 and 3.
