According to a publication by Shiseido Research Center in 2001(1), 2-nonenal is an unsaturated aldehyde with unpleasant odor caused by oxidative degradation reactions of ω-7 unsaturated fatty acids such as palmitoleic acid and bacenic acid found on the skin surface. This means that age-related oxidative stress is a cause of 2-nonenal. In other words, an increase in oxidative stress due to aging is the cause of age-related odor. We measured the change in age-related odor by reducing oxidative stress. Antioxidant composition Twendee X (TwX) was given who has age related odor for 4 weeks. The portable odor sensor KUNKUN BODY (Konica Minolta) was used for 10 participants to measure aging odor. Seventy-four participants were also monitored questionnaires. Several participants whose odor KUNKUN BODY scores were 80-100, which dropped scores to zero after 3 weeks. Seventy-two of the 74 cases showed a decrease in age-related odor. Oxidative stress increases with age and is a cause of many diseases. The development of age-related odors suggests increased oxidative stress. Reduction of age-related odors with the antioxidant composition TwX is suggested not only to reduce bad odors but also to maintain health. References: 1.Inufusa H.
