Composition for odor replenishment in younger women

Abstract

An object of the present invention is to provide a product as a countermeasure against aging note, which is suitable for younger women. Another object of the present invention is to provide a method for evaluating a substance having an antiaging effect by focusing attention on the age-related change in body odor in women. The present invention is a composition for odor replenishment in younger women, which contains at least a lactone compound represented by formula (I) and can be used for replenishing an odor component constituting the body odor of younger women. (In the formula, R representsan alkyl group having 2 to 9 carbon atoms.)

Description

technical field [0001] The present invention relates to compositions for replenishing youthful femininity. Background technique [0002] In recent years, both men and women, people's attention to smell etiquette has increased. Research on various body odors is being carried out intensively, and major causal odors such as sweat odor, underarm odor, foot odor, and old man's odor have been identified. One of the causes of, for example, body odor is thought to lie in fatty acids, unsaturated aldehydes, which are normally formed from sebum on the body surface. In addition, it has been reported that the smell called old man's smell is similarly oxidized and decomposed with omega-unsaturated fatty acids (palmitoleic acid, vacantoleic acid) produced by the decomposition of sebum to form a so-called 2-nonanoic acid on the body surface. Unsaturated aldehydes of alkenals are closely related (Non-Patent Document 1). [0003] As techniques for preventing such body odor such as old-fas...

[0004] On the other hand, although it is said that such body odor such as old man's smell exists in both men and women, the actual situation is that the research related to the change of body odor as women age has not been sufficiently conducted
