Deoco, a range of women’s beauty products that allegedly captures the coveted “young woman smell”, has become a huge hit in Japan, among both older women who want to smell younger and lonely men who crave the fragrance of a younger woman.
The story of this intriguing line of cosmetics began last year, when Japanese company Rohto Pharmaceutical announced that it had successfully isolated two fragrant chemical compounds, called Lactone C10 and C11, which younger women’s bodies seemed to produce in much larger quantities than those of older women. In a study that involved 500 women of all ages, from teens to adults in their 50s, Rohto’s scientists detected a “sweet aroma” that was stronger in younger women’s worn clothes. Subsequent research revealed that the scent came from two lactones, the levels of which were highest among teens, but dropped significantly in women over 35. After making the discovery and isolating the two compounds, Rohto quickly started working on Deoco, a line of body soaps and deodorants rich in Lactone C10 and C11.
