Can the senses be trusted? Do the test results truly establish a cause-effect relationship? Notions such as these, presented by keynote lecturer Michael Shermer, PhD, publisher of Skeptic magazine and regular contributor for the Scientific American journal, set the stage for the 2007 IFSCC Conference, held Sept. 24-26, in Amsterdam. Cosmetics & Toiletries magazine proudly sponsored this keynote that called on all scientists present to rethink the product claims they make through entertaining tales of falsified UFO photographs and demonic interpretations of backwards Led Zeppelin lyrics.
During the opening ceremony and welcome reception, Muchaneta G. Mutasa, an R&D chemist for Azochem Laboratories, was honored with the Maison G. de Navarre Young Scientist award. The first day of podium presentations highlighted the conference theme, “Building on Water.” Keynote lecturer Paul Matts, PhD, of P&G in the UK opened the session with his talk on the human skin as a “barrier factory.” He described skin as stiff, but like a “bendy straw” since excess skin allows the skin to bend. He added that something is needed in skin to plasticize this hard and stiff tegument so it does not crack, and water is an “incredibly effective” plasticizer.
The first day’s sessions focused on the natural moisturizing factor in skin, aquaporins and their role in retaining water in the skin, correlating age and quantifying product efficacy to skin via viscoelastic properties, and a full thickness skin model to replace animal testing. Additional topics ranged from in vivo monitoring of topical caffeine by Raman spectroscopy, water management of human hair and a depth profile of water amounts in skin depending on age, site, and more using spectroscopic effects; usual methods of measuring water in skin--what they tell researchers and what is ignored; rose fruit extract on facial pores; and teprenone to improve skin conditions, among others.
During the day’s sessions, a few interesting points were raised by audience members, such as:
The second days’ sessions included talks on preventing hair damage, a pigment with properties similar to snow for makeup, a decorin-like tetrapeptide to optimize organization of collagen fibers, testing of products without animals, Coenzyme Q10 for antiaging of hair, measurement of hair shine especially in blonde hair, photostability, quercetin encapsulation for stability and more.
