Description

  The present invention relates to a deodorant composition, and in particular, relates to a deodorant composition and a deodorization method that can reduce a composite odor derived from sweat odor, aldehydes, and the like and is safe for the human body.

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, deodorizing 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 aging 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.
Patent Document 8 discloses a deodorant composition containing cyclodextrin and describes the use of a primary amine compound as a buffering agent. However, there is no disclosure about exhibiting a high deodorizing effect by a specific combination of a primary amine compound and a nonionic compound.
Under such circumstances, there has been a demand for the development of a deodorant that can reduce the composite odor derived particularly from sweat odor and aldehydes and is safe for the human body.

That is, the log P value is an index of lipophilicity (hydrophobicity). The larger the value, the more hydrophobic, and the smaller the value, the more hydrophilic.
For the log P value, see, for example, Daylight Chemical Information Systems, Inc. The logP values of many compounds are listed in databases available from (Daylight CIS) and can be referred to.

  In the program “CLOGP”, the value of “calculated logP (ClogP)” calculated by the Hansch, Leo fragment approach is output together with the measured value of logP, if any. The fragment approach is based on the chemical structure of the compound and takes into account the number of atoms and the type of chemical bond (A. Leo, Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens, J. et al. B. Taylor and CA A. Ramsden, Eds., P. 295, Pergamon Press, 1990). Since this ClogP value is currently the most common and reliable estimate, it is preferable to use the ClogP value instead when there is no measured value of logP when selecting a compound. In the present invention, either an actual measured value of logP or a ClogP value calculated by the program “CLOGP” may be used. However, when there is an actual measured value, it is preferable to use the actual measured value.
