C'est ce qu'il ressort de la tres serieuse etude menee par la grande entreprise cosmetique
LION qui a fini par determiner ce qui rend les Japonais a partir de 30 ans, particulierement odorants. Il s'agirait d'une substance denommee l'
acide pelargonique contenu dans le sebum de ces messieurs, qui aurait la sale habitude de degager d'inopportunes effluves en se degradant. Mauvaise nouvelle. Bonne nouvelle, cette meme entreprise vient de decouvrir que la plante que l'on appelle l'
onagre ou
herbes aux anes en bon francais, serait souveraine dans la lutte contre ces odeurs fort indesirables dans tous les sens du terme. Avis donc a ceux d'entre les messieurs qui nous qui nous lisent et qui pensent souffrir du meme mal... odorant.
Et pour en savoir davantage, reportez-vous sans plus attendre a l'article paru sur le sujet, ce jour dans le quotidien national nippon

Men in their 30s raise a personal stink, and it smells like used cooking oilResearchers have concluded that men in their 30s smell primarily like used cooking oil, and the odor is caused by a chemical called pelargonic acid.
The research conducted by daily use products maker Lion was first undertaken after many male workers mentioned that when they entered their 30s their body odor seemed to change.
In a hunt for answers, the researchers undertook a study of male body odor over different age groups, with 148 men from their teens to their 70s taking part. The research subjects each wore T-shirts for 14 hours straight, after which the garments were handed over for testing.
The researchers analyzed the smell of different parts of the T-shirts, such as the back and chest areas. From the tests, it was determined that the odor of men in their 30s was different to that of younger men or boys, and also from the smell of older men.
The cause of the odor was traced to a type of skin oil. The oil, or sebum secretion, is a fatty substance produced by glands in the skin. The glands are especially common in the skin of the chest and back, and reach peak production when a man reaches his 30s. The smell itself is caused when these sebum secretions oxidize, producing the odorous pelargonic acid.
On the bright side for those 30-something men worried about their personal scent, researchers also found that the extract from seeds of the Evening Primrose flower can combat the oily odor. Turning this discovery to practical use, Lion is currently developing antiperspirants using Evening Primrose seed extract. The company expects to have products on the shelves for the olfactory self-conscious by this spring.
