Description

  The present invention relates to a spray deodorant composition, and more particularly to a spray deodorant composition and a deodorization method capable of reducing a composite odor derived from sweat odor and aldehydes.

A deodorant relieves an unpleasant odor together with a fragrance, and plays an important part in living a comfortable life. Recent needs regarding deodorization have changed from a fragrance that masks bad odor with a strong fragrance to a deodorant that eliminates the odor itself with a slight fragrance or no fragrance.
In addition, while there is an increasing laundry habit of wearing clothes that do not touch the skin directly, they do not wash immediately, but on the other hand, they are concerned about the smell of clothes that are not washed. Most of the unpleasant odors in the living environment are complex odors, and there is a need for a deodorant effective for these complex odors.

Conventionally, deodorization techniques for specific malodorous components are known, but few are effective for complex odors.
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. However, these liquid deodorizers do not have sufficient deodorizing performance for aldehydes and the like.
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. However, these also have insufficient deodorizing performance against sweat odors and aldehydes.

Patent Document 5 discloses that an anionic surfactant containing at least one selected from triethanolamine, tris (hydroxymethyl) aminomethane, and the like as a salt can suppress a complex odor in which lower fatty acids and amines coexist. Has been. However, an amine salt of an anionic surfactant is not suitable for preparing a deodorant composition because of its insufficient effect on aldehydes and poor solubility in water.
Patent Document 6 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. The salt does not have a sufficient deodorizing effect on aldehydes.
Patent Document 7 discloses that ethanolamine is effective for deodorizing unsaturated aldehydes such as nonanal, which is one of the causative substances of age-related odors recognized after middle-aged and older. There is no description about the effect on the above.
Under such circumstances, it has been desired to develop a deodorant composition that can reduce the composite odor derived from sweat odor and aldehydes.

In addition, as a fragrance | flavor, from 5 parts of ethyl cinnamate, 10 parts of linalyl acetate, 15 parts of laral parts, 10 parts of hexylcinnamic aldehyde, 10 parts of parride, 20 parts of phenylethylaldehyde, 10 parts of cedar alcohol, and 20 parts of limonene A blended fragrance was used.

<Preparation of deodorant object>
A cotton melias cloth (10 cm × 10 cm) is sprayed once with a spray vial (Marem Co., No. 6) as a odor component using a 10 ppm ethanol solution of isovaleric acid or 1% ethanol solution of nonanal, 30 After drying for minutes, a test piece was obtained.
<Deodorization method>
The test piece obtained by the above method was sprayed 6 times using a spray vial (Marum Co., No. 6) with a deodorant composition having the formulation shown in Table 1 and dried for 1 hour.
<Deodorization performance evaluation>
A total of 10 panelists, 5 males and 5 females in their 30s, smelled the test piece, 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 ○. The results are shown in Table 1.
