Description

  The present invention relates to a deodorant composition, and more particularly, to a deodorant composition and a deodorization method which are excellent in the effect of reducing a composite odor derived from sweat odor and aldehydes and are 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 composition composed of cyclodextrin, polyether-modified silicone (surfactant), primary amine (buffering agent), and the like. Patent Document 5 discloses a betaine-type amphoteric compound, a nonionic compound. A deodorant fiber capable of deodorizing ammonia odor and the like by treating with a treatment agent comprising an ionic surfactant and an anionic surfactant is disclosed. However, these also have insufficient deodorizing performance against sweat odors and aldehydes.

Patent Document 6 discloses that an anionic surfactant containing at least one selected from triethanolamine and tris (hydroxymethyl) aminomethane 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 7 discloses that organic dibasic acids or salts 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 8 discloses that ethanolamine is effective for deodorizing unsaturated aldehydes such as Nonenal, 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.
Under such circumstances, it has been desired to develop a deodorant composition that can reduce the composite odor particularly derived from sweat odor and aldehydes and is safe for the human body.
