Proctor & Gamble’s principal scientist, Russell Elliott, will help attendees face the challenges of handling nanoparticles in complex cosmetic systems. Nanoparticle sunscreen formulas, for example, have a high surface area that can cause them to deplete emulsifier/dispersant from other particles and/or the emulsion itself, causing instability. Elliott will explain an approach to prevent this effect using fibril coatings chemically bonded on the nanoparticles. Following Elliott, Luigi Rigano (Luigi Rigano Laboratories) will describe antioxidants and their role in preventing aging; modern strategies to adopt for limiting unwanted oxidation reactions in the skin will be discussed, focusing on new and recently available vegetal actives.
Day one will close with Barbara Brockway’s (Optima Chemicals) discussion on advanced silicone-in-water combinations for skin care. New silicone-in-water emulsions and the latest hybrid silicone composite powders could deliver important product sensory characteristics. Brockway suggest how, used together, they improve feel and can be incorporated into highly volatile and mixed polar phases.
Leading into in-cosmetics, day two of ATC Barcelona will open with Alverio Malpede’s (Cosmetic Division, Prodotti Gianni) coverage of trends in cosmetic raw materials. According to Malpede, the overall trend is to launch new ingredients that blur the demarcation line between cosmetic and dermatological products while providing ingredients perceived as safe and natural. Theresa Callaghan (proDerm Institute for Applied Dermatological Research) will take a closer look at two consumer trends, the concerns for cellulite and aging, and investigates whether cellulite is an aging phenomenon. The role of hormones, lymph flux, vascularity, inflammation, adipose biochemistry, and stress-related aging effects on connective and adipose tissue, in the occurrence of cellulite, will be considered.
Another facet of aging will be given by Nalini Kaul, Ph.D. (Hill Top Research, Inc.). Consumers opposed to invasive and expensive procedures need easily accessible products with proven antiaging efficacy, according to Kaul. The antiaging concept includes the prevention of, reversal of, and restoration from the effects of aging. Antioxidants, botanicals, moisturizers and sunscreens are a part of the antiaging market and current clinical designs and sophisticated instrumentation methods used for claim support for these products will be presented.
Finally, Conference Chair Johann Wiechers, Ph.D. (Uniqema), discusses studies strongly suggesting the existence of a connection between the mind and the body and examines how to substantiate such “mind” claims.
