In 2001, Japanese researchers reported that after the age of 40, some individuals develop a malodor known as “aging odor,” attributed to the presence of unsaturated C9, 2-nonenal. George Preti, PhD, a member of Monell Chemical Senses Center and an adjunct professor of dermatology at the University of Pennsylvania School of Medicine, was interested by this report and began to conduct research of his own.

The antioxidant potential of cosmetic materials can be evaluated by several methodologies, including a commercial kit that measures total antioxidant status, as illustrated here with a commercial extract from the fruit of the açaí, a Brazilian palm tree. Applications in antiaging products are suggested.

Nowadays, however, personal care has evolved even further to encompass the root of human being-ethics and morals, where the purchase of a personal care item relates to one’s concern about the environment and animal welfare. But the involvement of ethics does not just apply to the consumers using the products; it applies to scientists conducting safety studies.
