Description

[Technical field]

[0001] The present invention relates to a fragrance composition, more specifically to a fragrance composition that suppresses fatty acid odor and that is capable of exhibiting a good fragrance by using a specific combination of natural fragrances without causing the odor characteristic of a cleaning composition containing a salt of a higher fatty acid, and to a skin cleansing composition that is characterized by containing the fatty acid odor suppressing fragrance composition. [Background technology]

[0002] 2. Description of the Related Art In the field of cosmetics and the like, masking undesirable odors during product production using various fragrances is a commonly used and widely applied technique (see Non-Patent Documents 1 and 2).

[0003] The above-mentioned masking technology is also applied to the field of detergent compositions such as shampoos and body soaps, and plays a major role in reducing the odor of raw materials in products and improving their palatability. In particular, since higher fatty acid salts, which are used as the main components of skin cleansers, have a characteristic fatty acid odor, it is common to use fragrances to mask the odor when using them as cleansers (see Patent Document 1).

[0004] However, in response to the growing consumer trend toward natural products in recent years, there is a demand for fragrance compositions that suppress fatty acid odors consisting only of natural fragrances, and for skin cleansing compositions that contain such fragrance compositions. Meanwhile, technology that can mask fatty acid odors using only natural fragrances and that can also present a pleasant fragrance is still under research, and this is an area in which future technological development is expected.
