Description

  The present invention relates to a wrinkle-removing deodorant composition, and more specifically, a wrinkle-removing deodorant composition that is excellent in the effect of reducing composite odor and can remove wrinkles without impairing the texture of the textile product, and wrinkle The deodorizing method

Due to changes in washing habits, clothes that do not touch the skin directly have increased the habit of not being washed immediately, but on the other hand, I am concerned about wrinkles and smells of clothes that are not washed. There is a need for a deodorizing performance against a strong odor (complex odor). So far, effective deodorizers for specific malodorous components are known, but few are effective for complex odors.
In addition, dry cleaning clothing such as suits is difficult to wash with water at home, and for wrinkle removal methods, there is generally a method of heat treatment such as ironing and steam press, but it is a laborious work, The texture may be damaged. So far, techniques for stretching wrinkles of clothing without heat treatment have been disclosed, but the effect of removing wrinkles is insufficient.

For example, Patent Document 1 discloses a liquid deodorant that deodorizes sweat odor and tobacco odor by using a cationic or amphoteric surfactant in combination with a chelating agent. Patent Document 2 discloses a fragrance or the like. The liquid deodorant which deodorizes sweat odor by using together the deodorizing base of this, a cationic surfactant, and a specific solvent is disclosed. Patent Document 3 discloses that a deodorant containing an organic dibasic acid or a salt thereof is effective for deodorizing lower fatty acids and amines. However, these liquid deodorants do not have sufficient deodorizing performance against aldehydes and the like.
Patent Document 4 discloses a deodorant composition that suppresses spoilage odor by using a deodorant base material mainly composed of an extract from a plant, a fragrance, ethanol, and a surfactant. No. 5 discloses a deodorant fiber capable of deodorizing ammonia odor and the like by treatment with a treatment agent comprising a betaine amphoteric, nonionic, and anionic surfactant. However, these also have insufficient deodorizing performance against sweat odors and aldehydes.

Patent Document 6 discloses a composition that can suppress a complex odor in which a lower fatty acid and an amine coexist with an anionic surfactant containing tris (hydroxymethyl) aminomethane or the like as a salt. However, this amine salt is not sufficiently effective against aldehydes, and some have poor solubility in water, so the range of use is limited.
Patent Document 7 discloses that a deodorant containing ethanolamine is effective for deodorizing unsaturated aldehydes such as Nonenal, which is one of the causative substances of age-related odors recognized after middle-aged and older. . However, the effect on sweat odor is unknown, and ethanolamine is irritating and is not suitable for use in a form that may touch the human body.

Further, Patent Document 8 discloses a fabric wrinkle removing composition comprising alcohol, glycerin, a nonionic surfactant and water, but this composition should sufficiently remove wrinkles only by natural drying. I can't.
Patent Document 9 discloses a composition for removing wrinkles, which is a combination of water and a water-soluble solvent such as hexylene glycol and isoprene glycol, but this composition can remove light wrinkles on clothes, but deep wrinkles. It is difficult to remove completely.
Patent Document 10 discloses a deodorizing antibacterial wrinkle removing composition such as tobacco odor, which uses a combination of a polyether-modified silicone, a quaternary ammonium type antibacterial agent and a deodorizing base extracted from plants. Deodorant performance against odor is not sufficient.
From this situation, the composite odor derived from sweat odor and aldehydes can be reduced, and even without heat treatment such as ironing or steam pressing, wrinkles of the textile product can be removed without impairing the texture. It has been desired to develop a wrinkle-removing deodorant composition.

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 ○. The results are shown in Table 1.

<Wrinkle method>
After wetting the test cloth 20 × 10cm made of wool fabric (Wool Surge, Tanigami Shoten) with ion-exchange water by spraying, the test cloth is folded in two and the crease part is set in a temperature-controlled room set at 40 ° C. A weight of 2 kg was put on and wrinkled by leaving it for 24 hours, and this was used as a model for evaluating wrinkle removal.
<Wrinkle removal method>
When the test cloth is dried using the spray container (T-7500, manufactured by Canyon Co., Ltd.), the wrinkle-removing deodorant composition shown in Table 1 is applied to the model wrinkled test cloth prepared by the above method. After spraying 50% by weight with respect to the weight, it was allowed to stand in a temperature-controlled room at 25 ° C./50% RH for 12 hours and dried naturally. After drying, the wrinkle removal degree of the test cloth was evaluated by the following method.
<Evaluation of wrinkle removal performance>
Five skilled panelists evaluated the cloth sprayed with the wrinkle-removing deodorant composition and the cloth (control) before the treatment according to the following criteria, and the average score was obtained.
1: No wrinkles 2: Little wrinkles 3: Slightly wrinkles remain 4: Corresponding wrinkles remain 5: Remarkably wrinkles remain Average points 1 to less than 2 ◎ 2 to less than 3 ◯: 3 or more and less than 4 were evaluated as Δ, and 4 or more and 5 or less as x. Practically, 又 は or ○ is preferable.

  From Table 1, the compositions of Comparative Examples 1 and 2 have insufficient deodorant performance and wrinkle removal performance against sweat and aldehyde odors, whereas the deodorant compositions of Examples 1 to 3 It can be seen that the deodorizing performance is high and the wrinkle removing performance is high with respect to both sweat odor and aldehyde odor.

Example 4
As a result of evaluating the deodorizing performance by the above method, the wrinkle removing deodorant composition of Example 1 has a high deodorizing performance with respect to both sweat odor and aldehyde odor, and the flavor of the blended fragrance The tone was maintained.

  According to the wrinkle-removing deodorant composition of the present invention, it is excellent in the effect of reducing the composite odor derived from sweat odor and aldehydes, is easy to prepare an aqueous composition, and is safe to touch the human body, Even without heat treatment such as ironing or steam pressing, wrinkles can be removed without impairing the texture of the textile product. For this reason, it can be suitably used as a wrinkle-removing deodorant composition for composite odors adhering to objects such as fabrics such as handkerchiefs, clothing such as suits and sweaters, and textiles such as curtains and sofas.
