Description

The present invention relates to a deodorant composition used for deodorizing a wide variety of offensive odors and malodors generated in the home. More specifically, the present invention relates to filth generated in the home, tobacco odor in the toilet, living room, etc., cooking odor in the kitchen, odor generated from kitchen waste, muffled odor in the bathroom, odor derived from mold, etc. Just by contacting with the odor generated from the air conditioner, ash tray, odor derived from pets, etc., not only the odor emitted but also the odor generated afterwards is suppressed by suppressing rot, and the indoor environment etc. is improved. With respect to a deodorant composition that can.

Generally, bad odors that occur in the home include tobacco odors in the toilet and living room, kitchen cooking odors, kitchen odors, bathroom odors, mold odors, and air conditioner odors. There is. In particular, in recent years, care for bad odors has become important due to the improvement of the airtightness of the space due to changes in the living environment. Conventionally, methods for eliminating such malodors include masking of malodors with air fresheners, neutralization methods with acidic or alkaline substances, ventilation, and physical removal methods for adsorbing on activated carbon. A wide variety of deodorants based on are commercially available.

On the other hand, there is also a biological deodorizing method that kills microorganisms that cause putrefaction to prevent putrefaction and prevent the generation of foul odors. This deodorizing method is not suitable for the purpose of removing the odor of the atmosphere and has a drawback that it takes time to develop the deodorizing effect, but the deodorizing can be performed more effectively by combining with a deodorant. Is possible. For example, a deodorant composition (Japanese Patent Laid-Open No. 2001-178806) that combines a plant extract, a fragrance, ethanol, and a surfactant has been proposed.
The present invention is effective in suppressing odor generated from a small amount of malodor source, but for example, an amine system typified by trimethylamine generated from kitchen waste (meat, fish, etc.) laminated on a triangular corner in a sink, a trash can, or the like. A sufficient deodorizing effect cannot be obtained at a pH of neutral or higher with respect to the putrefactive odor. Further, even if the deodorant containing the antibacterial agent has an antibacterial effect on the microorganisms on the surface, it cannot suppress the internal putrefaction, and as a result, the effect of preventing the bad odor cannot be expected.

Japanese Unexamined Patent Publication No. 2001-178806

Therefore, the present invention has a bad odor generated in the home, such as a cigarette odor in a toilet or a living room, a shoe odor at the entrance, a cloth product odor such as bedding, a manure odor in pet sand, a kitchen cooking odor, and a putrefaction of a drain. Not only odors, muffled odors in bathrooms, odors derived from mold, odors generated from air conditioners, etc., but also amine-based and mercaptan-based odors generated from kitchen waste stacked in triangular corners in sinks, trash boxes, etc. It is an object of the present invention to provide a deodorant composition capable of alleviating a bad odor even with respect to a bad odor source.

As a result of diligent research to solve the above problems, the present inventor has (A) a plant extract (B) a fragrance, (C) ethanol, and (D) a cationic surfactant having an alkyl group having 10 to 14 carbon atoms. By using an activator, a deodorant composition having the above-mentioned desired performance has been found.

The deodorant composition of the present invention can alleviate the malodor only by contacting it with the surface of the malodor source, spreads to every corner of the malodor source, and can suppress the generation of the malodor by preventing putrefaction.

Hereinafter, the present invention will be described in more detail. It is necessary to contain (A) a plant extract, (B) a fragrance, (C) ethanol and (D) a cationic surfactant having an alkyl group having 10 to 14 carbon atoms of the present invention.

The deodorant composition having the composition shown in Table 1 was prepared according to the information, and the deodorizing effect and the effect of suppressing the generation of malodor, that is, the antiseptic effect were measured by the following methods. As for the content of each component shown in Table 1, the component (A) indicates the content of the raw material as it is, and the other components indicate the content of the pure content.

<Evaluation method of deodorant effect>
50 g of shredded cabbage or ground sardines was placed in a 1-liter wide-mouthed jar, covered, and left at 25 ° C. for 48 hours to spoil. Each bottle was sprayed with 5 ml of the composition evenly on the surface, covered with a lid for 10 minutes and allowed to stand, and then the malodor intensity in the bottle was sensory evaluated by 5 panelists. At the time of evaluation, the malodor intensity in the bottle without spraying anything was set as "XX", and the average value of the evaluation results according to the following evaluation criteria is shown in the table.
Offensive odor intensity
◎: I feel a faint odor
〇: I feel a weak odor
△: I feel a normal odor
×: I feel a strong odor
XX: I feel an extremely strong odor

<Effect of suppressing the generation of foul odors>
50 g of shredded cabbage or ground sardines was placed in a 1 liter wide-mouthed jar, 5 ml of the composition was sprayed evenly on the surface, covered, and left at 25 ° C. for 48 hours. The odor in the bottle that was not sprayed was set to 5, and the average value of the evaluation results according to the above evaluation criteria is shown in the table. The lower the score, the more the generation of foul odor was suppressed, that is, the more the putrefaction was suppressed.

As shown in Table 1, the deodorant composition of the present invention had an excellent deodorizing effect and an excellent malodor preventing effect by suppressing putrefaction. On the other hand, in the comparative example, it can be seen that the deodorizing effect and the malodor preventing effect are not sufficient.
