This article fell a bit short of an explanation, as I still don't know how 2-Nonenal got there on the first place..

  If you click the "2001 study" link, there's more detail, including: > Furthermore, analysis of skin surface lipids revealed that w7 unsaturated fatty acids and lipid peroxides also increased with aging and that there were positive correlations between the amount of 2-nonenal in body odor and the amount of w7 unsaturated fatty acids or lipid peroxides in skin surface lipids. > 2-Nonenal was generated only when w7 unsaturated fatty acids were degraded by degradation tests in which some main components of skin surface lipids were oxidatively decomposed using lipid peroxides as initiator of an oxidative chain reaction. The results indicate that 2-nonenal is generated by the oxidative degradation of w7 unsaturated fatty acids, and suggest that 2-nonenal may be involved in the age-related change of body odor. Is there an a organic-chemistry dermatologist in the house?

    It would seem reasonable to think that age-related slackening of the skin may have something to do with this.

      Assuming their hypothesis is correct, I'd like to know where/when the W7 molecules are breaking down. If it occurs gradually at the surface, then it may be something you can treat topically with soaps or creams.
