Abstract
Human body odor consists of various kinds of odor components. 2-Nonenal, an unsaturated aldehyde, is main causative substance of the aged body odor. We found that the polyphenol mixture extracted (anti-nonenal Polyphenol Complex) from an oolong tea, a tiencha, a green tea and an astringent persimmon had high anti-oxidative effect and deodorant effect against 2-nonenal. Human study for 4 weeks was conducted to investigate the deodorant effect of soap containing anti-nonenal PC for 20 men between the ages of 43 and 75. By using the soap everyday, the amount of 2-nonenal from body decreased significantly. The odor intensity and the visual analogue scale (VAS) were also significantly improved. We concluded that the soap containing anti-nonenal PC had high deodorant effect against the aged men’s body odor.
