[0002]

[0001] The present invention relates to an oxidizing agent-containing composition having a stable odor.

[0003]

2. Description of the Related Art Bleaching agents are classified into chlorine bleaching agents and oxygen bleaching agents. Chlorine bleaching agents have high bleaching power, and oxygen bleaching agents can be used for colors and patterns. ing. Recently, oxygen-based bleaches have become the mainstream in the field of bleaches for clothing due to improvements in bleaching techniques for oxygen-based bleaches. As the oxygen-based bleaching agent, there are a powder type and a liquid type, each of which has characteristics. The liquid type is recognized for its ease of use and has been widely used.

[0004] The bleaching agent is an oxidizing bleaching agent, and the stability of a composition containing the bleaching agent is a problem. In particular, limonene, short-chain ester, lactone, menthol and the like are known as components for refreshing the fragrance of the composition, and are indispensable components for flavors such as citrus, fruity and mint. However, in oxidizing compositions, especially in liquid compositions, deterioration of these odors has been a problem.

In general, compounds such as those described in "Synthetic Perfume Chemistry and Product Knowledge" (Genichi Indo, Chemical Daily) are used as perfume components. It is known that many of these are unstable to oxidizing bleaches, and their stability has been studied. For example, relatively stable fragrance compositions for these bleaching agents are disclosed in JP-A-3-115399, JP-A-7-216972, and JP-A-11-29793.

No. 9793 discloses a liquid bleach containing hydrogen peroxide, a specific nonionic surfactant and a specific fragrance component in a specific ratio, which does not cause deterioration of the odor of the fragrance component. But,
In these technologies, the functional group and structure of the compound are limited, and the fragrance of the composition is limited to a specific herbal or floral tone, and it is difficult to obtain a wide range of fragrances including citrus and fruit tones Met. Also, there are cases where the aroma stability is not always sufficient such as long-term storage.

[0006]

DISCLOSURE OF THE INVENTION The present invention provides an oxidizing agent-containing composition having a stable odor during long-term storage.
