Description

  The present invention relates to a wrinkle removing deodorant composition and a method for removing wrinkles.

  Due to changes in washing habits, clothing that does not touch the skin directly has increased the habit of not washing immediately, but on the other hand, I am concerned about wrinkles and smells of clothes that are not washed, Deodorizing performance is required. 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 surfactant or an amphoteric surfactant in combination with a chelating agent. A liquid deodorant that deodorizes sweat odor by using a deodorant base such as a fragrance, a cationic surfactant and a specific solvent in combination is disclosed. Patent Document 3 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. 4 discloses a deodorant fiber capable of deodorizing ammonia odor and the like by treatment with a treatment agent comprising a betaine amphoteric compound, a nonionic surfactant, and an anionic surfactant. Patent Document 5 discloses that an organic dibasic acid or a salt thereof can deodorize lower fatty acids such as acetic acid and isovaleric acid and amines such as ammonia and trimethylamine. However, these liquid deodorants have insufficient wrinkle removal performance. The organic dibasic acid or the salt thereof of Patent Document 5 does not have a sufficient deodorizing effect on aldehydes.

  Patent Document 6 describes a technique in which a wrinkle part of a garment is sprayed with a composition obtained by combining a specific water-soluble solvent such as hexylene glycol and isoprene glycol and water, and then left to stand to remove the wrinkle part. Although this method can remove light wrinkles on clothing, it is difficult to completely remove deep wrinkles. Patent Document 7 discloses a technique of removing wrinkles by spraying and spraying a composition comprising a specific alcohol, glycerin, nonionic surfactant and water on a fabric and then naturally drying or ironing. However, it is difficult to remove wrinkles by air drying alone, and ironing is very effective for removing wrinkles, but it is a time-consuming work and can damage the texture. There is sex. Patent Document 8 describes a technique related to a deodorant (such as a tobacco odor) antibacterial wrinkle remover by using a polyether-modified silicone, a quaternary ammonium type antibacterial agent and a deodorant base extracted from plants. Deodorant performance and wrinkle removal performance are not sufficient.

From this situation, wrinkle cancellation that has high deodorizing performance for textiles and can remove wrinkles of textiles without damaging the texture without heat treatment such as ironing or steam press. Development of an odorant composition has been desired. That is, a technology that achieves both a deodorizing performance and a wrinkle removal performance at a high level is desired.

<Evaluation of deodorizing effect>
In addition to the aldehyde odor generated by the oxidation of sweat odor and sebum, sebum odor or other odors of dirt are attached to the actually worn clothing, which is a composite odor. Therefore, the following deodorization evaluation was performed.

(1) Preparation of deodorant object Three males in their 30s wore commercially available 100% cotton long pants when commuting (summer, every other day for 5 days) and then collected. From the thigh contact part (front surface), 4 sheets on the left and 4 sheets on the right were cut (10 cm × 10 cm) to obtain test pieces. In addition, it was confirmed that the test pieces obtained from the same examiner had no difference in adhesion odor or dirt depending on the cut site (left and right, top and bottom).

(2) Deodorizing method The test piece obtained by the above method was sprayed 6 times using a spray vial (Marum Co., No. 6) with a wrinkle-removing deodorant composition having the formulation shown in Table 1.

(3) Deodorization performance evaluation Eight types of examples, comparative examples, and reference examples were evaluated using a total of eight test pieces obtained from the same exhibitor. Moreover, since the test piece was created from three exhibitors, it evaluated three times each about the Example, the comparative example , and the reference example . Tests after spraying a wrinkle-removing deodorant composition on a total of 10 panelists of 5 males and 5 females in their 30s and after standing in a temperature-controlled room at 25 ° C./50% RH for 3 hours The smell of a piece was sniffed, the odor intensity against an unpleasant odor was evaluated in the following 6 levels, and the average value was obtained and shown in the table.
0: Do not feel unpleasant odors at all 1: Strength to feel slightly unpleasant odors 2: Weak odors that easily feel unpleasant odors 3: Smells that clearly feel unpleasant odors 4: Strong odors 5: Unbearable The stronger odor evaluation is preferably less than 2 on average. When the average value is 2 or more, the deodorizing effect is insufficient and the product is not suitable.

<Evaluation of wrinkle removal effect>
(1) Method of wrinkling After wetting the test cloth 20cm × 10cm made of wool fabric (Wool Surge, Tanigami Shoten) with ion-exchange water by spraying, the test cloth is folded in half and heated to 40 ° C. A weight of 2 kg was placed on the crease in a set temperature chamber and left for 24 hours to make a wrinkle removal evaluation model.

(2) Wrinkle removal method For the test cloth with the model wrinkle created by the above method, use a wrinkle removal deodorant composition shown in Table 1 as a test cloth using a spray container (T-7500, manufactured by Canyon). After spraying 50% by mass with respect to the mass at the time of drying, it was left to stand in a constant temperature room at 25 ° C./50% RH for 12 hours and dried naturally. After completion of drying, the degree of wrinkle removal of the test cloth was determined.

(3) Wrinkle removal performance evaluation Judgment is made by scoring the cloth treated with the wrinkle removal deodorant composition and the cloth before the treatment (control) according to the following criteria by five experienced panelists. The average score was determined and shown in the table. An average score of less than 3 is preferred.
1: No wrinkles 2: Almost no wrinkles 3: Slight wrinkles remain 4: Corresponding wrinkles remain 5: Remarkably wrinkles remain

From Table 1, while the composition of Comparative Examples 1-3 is inadequate in either the deodorizing performance or wrinkle removal performance with respect to wearing trousers, the wrinkle removal deodorant composition of Examples 1-2 is It can be seen that the deodorizing performance for the worn pants is high and the wrinkle removal performance is also high.
