Description

TECHNICAL FIELD The present invention relates to a deodorant composition. BACKGROUND ART In the related art, chemical deodorants (Patent Literatures 1 and 2) using a natural extract from a plant and sensory deodorants (Patent Literatures 3 and 4) using a blended fragrance have been reported as deodorants used for removing a nitrogen-based malodor, a sulfur-based malodor, and an acid-based malodor. US 2017/360822 Al describes a malodor neutralizing composition comprising hyaluronic acid or a salt thereof (HA), N-acetyl cysteine or a pharmaceutically or cosmetically acceptable derivative thereof (NAC), and a pharmaceutically or cosmetically acceptable malodor neutralizing agent. US 2010/111889 Al concerns a malodor control system suitable for use in disposable articles, which may comprise an aldehyde, an ester, an ionone, and optionally a macrocyclic musk. The system may optionally include a perfume. JP 2001 348308 A relates to a bacteria metabolism inhibitor which contains one or more kinds of compounds selected from 87 kinds of specified perfumes and chemical substances. CITATION LIST PATENT LITERATURE Patent Literature 1: JP-A-S61-206448Patent Literature 2: JP-A-H11-178907Patent Literature 3: JP-A-2003-137758Patent Literature 4: JP-A-2004-018431 SUMMARY OF INVENTION TECHNICAL PROBLEM However, for the deodorant using a natural extract, what kind of substance acts as an active ingredient has not been elucidated in many cases. In addition, even if the active ingredient is elucidated, a process for separating these active ingredients is often complicated, and the price of the deodorant becomes expensive, which is not industrially advantageous. For the deodorant using a blended fragrance, a masking effect is often obtained by strong fragrance, and a user may feel uncomfortable. In addition, although a temporary masking effect can be obtained, the malodor is not fundamentally removed, and therefore, there is a disadvantage that the malodor is felt again over time. Accordingly, an object of the present invention is to provide a deodorant composition that can chemically deodorize and remove a nitrogen-based malodor of ammonia, amines, or the like, a sulfur-based malodor of mercaptans, sulfides, or the like, and an acid-based malodor of lower fatty acids or the like, and can allow a user to get a fresh feeling sensuously and can impart a fresh feeling. SOLUTION TO PROBLEM As a result of studies to solve the above problems, the present inventors have found that a deodorant composition containing both compounds, dihydrocitronellal and hydroxycitronellal has a high deodorization effect both chemically and sensuously, and have completed the present invention. That is, the present invention includes the following contents [1] to [5]. [1] A deodorant composition containing dihydrocitronellal and hydroxycitronellal.[2] The deodorant composition according to [1], in which a mass ratio of dihydrocitronellal to hydroxycitronellal is 20:80 to 80:20.[3] The deodorant composition according to [2], in which the mass ratio is 50:50 to 80:20.[4] The deodorant composition according to any one of [1] to [3], in which a deodorant target is at least one compound selected from the group consisting of ammonia, amines, mercaptans, sulfides, and acid-based malodorous ingredients selected from the group consisting of acetic acid, propionic acid, normal-butyric acid, isobutyric acid, normal-valeric acid, isovaleric acid, hexanoic acid, heptanoic acid, octanoic acid, 2-methylbutyric acid, 4-methylpentanoic acid, 4-methyl-3-pentenoic acid, 4-methylhexanoic acid, 4-methyl-3-hexenoic acid, 3-methyl-2-hexenoic acid, and 2-ethylhexanoic acid.[5] A consumer product containing 0.001 mass% to 30 mass% of the deodorant composition according to any one of [1] to [4]. ADVANTAGEOUS EFFECTS OF INVENTION The deodorant composition of the present invention can chemically deodorize and remove a nitrogen-based malodor of ammonia, amines, or the like, a sulfur-based malodor of mercaptans, sulfides, or the like, and an acid-based malodor of lower fatty acids or the like, and can allow a user to get a fresh feeling sensuously and can impart a fresh feeling. DESCRIPTION OF EMBODIMENTS Hereinafter, a deodorant composition of the present invention will be described in detail. The deodorant composition of the present invention contains both compounds, dihydrocitronellal and hydroxycitronellal as an active ingredient. As dihydrocitronellal and hydroxycitronellal, commercially available ones may be used, or those obtained by a known production method may be used. A mass ratio of dihydrocitronellal (A) to hydroxycitronellal (B) in the deodorant composition of the present invention is not strictly limited, and the mass ratio of (A):(B) is preferably 20:80 to 80:20, and more preferably 50:50 to 80:20. Examples of malodorous ingredients targeted by the deodorant composition of the present invention include nitrogen-based malodorous ingredients such as ammonia, methylamine
