Description

  The present invention relates to a deodorant composition.

  There are a variety of odors that occur in daily life, but the sources are drains, toilets, baths, clogs, garbage, dishes, cigarettes, sweat, sebum, etc. Repeated absorption and dissipation through the body, furniture, clothing, etc., mixed odors sometimes drift in the space, causing discomfort. It is most effective to cut off the source of the odor, and deodorants corresponding to individual sources are on the market, but it is not appropriate to cut off the source during the generation of odors such as cooking and cigarettes There is also a smell. On the other hand, deodorants that appeal to the odor drifting in the space after the occurrence are released, but most of them are dedicated to the space, and the deodorizing system also has a masking effect by the fragrance and odor molecules by the adsorbent. Many are due to the adsorption of. The adsorption action by the adsorbent is effective in reducing odorous molecules in the space, but is known to be inferior in immediate effect because it becomes diffusion-limited. There is a need for a quick-acting and highly effective deodorant that can easily cope with both odors in the space and odor sources.

Patent Document 1 discloses a fragrance composition excellent in fragrance characteristics such as fragrance and residual fragrance and retention effect, obtained by premixing alkyl glyceryl ether and a fragrance, and a cosmetic containing this fragrance composition. , Toiletry products, and fragrances. Patent Documents 2 and 3 disclose the use of a composition containing an alkyl glyceryl ether as a method for sterilizing the surface of an article, and have a deodorizing effect on odors derived from bacteria that are reduced by sterilization.

  However, Patent Document 1 does not suggest any solution for the problem of floor wetting when spraying a deodorant into a space. In Patent Documents 2 and 3, the deodorizing effect when sprayed into a space is not clear. Patent Document 4 is a technique of a cleaning agent for hair and body, and does not relate to a deodorant that smells in the space. Patent document 5 is mainly intended for the synergistic action of antibacterial effect by the combined use of zinc and alkyl glyceryl ether, and does not give any suggestion to the solution of the problem at the time of space spraying. Patent Document 6 is a technique for dealing with odors generated by bacteria on the skin, and is not foreseen with regard to application development to space deodorization. In addition, Patent Document 7 has a problem that the water content is as low as 20% or less, and the deodorizing effect on water-soluble odor is low.

  On the other hand, a method in which a water-based deodorant is placed in a spray-type container and sprayed directly onto the odor source and the space can easily deal with both the space and the odor source. In order to reduce this, the spray particle size needs to be a certain level or more, and the mist sprayed in the space falls on the floor and wets the floor. At that time, if the mist adhering to the floor does not dry quickly, it may cause floor slipping, stickiness, etc., so it is desirable that the drying speed of the mist is high.

The air supply / exhaust system is stopped in a walk indraft measuring 1 m in front, 50 cm in depth, and 2 m in height, and three commercially available cigarettes (mild sevens) are simultaneously ignited on an ashtray placed on the floor and burned for 5 minutes. After the cigarette smoke was filled, the cigarette was extinguished to make a test space.

(2) Deodorizing method The test piece obtained by the above method was mixed with a deodorant composition having the formulation shown in Table 2 on a model sweat test cloth as a spray vial (Marem Co., No. 6, volume of spray particles) Sprayed 6 times using a mean particle size of 60 μm (total of about 0.24 g), and the model tobacco test cloth (30 cm × 30 cm) had a direct pressure trigger made by Canyon (about 1 ml / stroke, volume average particle size of spray particles) Using a diameter of 110 μm, spraying was performed once at four locations separated from each other by 10 cm or more (total of about 4 g), and each was dried for 1 hour.

  On the other hand, for the space filled with the model tobacco odor, 10 minutes after extinguishing the tobacco, a walk-in raft using a canyon direct pressure trigger (about 1 ml / 1 stroke, volume average particle size of spray particles 110 μm) is used. Spraying was performed 5 times in the horizontal direction from a position with a height of 1.5 m on the right wall, and the odor was evaluated after standing for 10 minutes.

(3) Deodorant performance evaluation For test pieces (sweat odor (on fabric) and tobacco odor (on fabric)), a deodorant was applied to a total of 10 skilled panelists, including five men in their 30s and five women. For the space (tobacco odor (cloth space)), spray the composition 5 times, and then let it smell for the space after being left for 10 minutes. Each was evaluated by the following 6-step odor intensity display method, and the average value was obtained.
0: Odorless 1: Strength of feeling something slightly but not knowing what odor (detection threshold level)
2: Know what odor, easily feel weak odor (recognition threshold level)
3: Obvious odor 4: Strong odor 5: Unacceptably strong odor Average value 0 to less than 1, ◎, average value 1 to less than 2 ○, average value 2 to less than 3 △, average value 3 to 5 The following was evaluated as x. The evaluation is preferably ◎ or ○.

<Evaluation of drying speed>
A flooring floor with a commercial decorative plywood finish was cut into 30 cm × 30 cm board pieces, and the drying rate was evaluated on the surface. After measuring the initial mass M0 (g) of the plate piece in an evaluation chamber at a humidity of 60% and a temperature of 20 ° C., the plate piece was placed flat on a balance and Yoshino M3 trigger (0.5 ml / 1 stroke, volume of spray particles) Each composition in Table 2 was sprayed in a direction parallel to the plate surface from a position of 10 cm in height and 10 cm in front of the plate piece using an average particle size of 95 μm. The sum total of the mass of the board piece and the attached composition was confirmed, and the composition dropped on the board piece was adjusted to 0.40 g (M0 + 0.40 g). The total mass (plate piece + composition) after 5 minutes from here is measured as M5 (g), and the value A (%) obtained by ((1- (M5-M0) /0.40)) × 100 Was calculated. A series of operations from measuring the initial mass M0 of this plate piece to measuring the mass M5 after 5 minutes was repeated five times to obtain five values A, and the average value was obtained. The 1's place of the average value was rounded off to obtain the drying rate (%).

  From Table 2, the deodorant composition of the comparative example has a deodorant performance with respect to sweat odor and tobacco odor, and a drying rate when adhering to the floor is insufficient. Has high deodorizing performance for both sweat odor and cigarette odor, and the drying speed when adhering to the floor is faster than the comparative example.
