Description

Technical Field

[0001] The present invention relates to a detergent composition.

Background Art

[0002] In the field of cosmetics and the like, masking unpleasant odors during product manufacturing using various fragrances is a widely applied general technique (see Non-Patent Documents 1 and 2).

[0003] The above masking technique is also applied to the field of detergent compositions such as shampoos and body soaps, and plays a major role in reducing the raw material odor of products and improving palatability. In particular, since surfactants used as the main component of skin detergent compositions have a specific odor, it is common to mask the odor with fragrances when using them as skin detergent compositions (Patent Documents 1 and 2).

[0004] In response to the recent increasing trend of consumers towards natural products, there is a demand for a fragrance composition that suppresses the odor of surfactants composed only of natural fragrances, and a skin detergent composition containing such a fragrance composition. A technology that enables masking the odor of surfactants only with natural fragrances and exhibits good fragrance development is under research, and is an area expected for future technological development.
