Outdoor, indoor and self-tanning products have different usage profiles, thus fragrancing each product type has special considerations with respect to the overall fragrance structure and the types of characters that work best. The present article reviews fragrance structure and discusses specific considerations for each product type to assist formulators in designing successful sun care products.

Previous studies demonstrate that skin buffering capacity can be measured in vitro by applying several concentrations of hydrogen chloride (HCl) and sodium hydroxide (NaOH) on skin and evaluating the pH change pre- and post-dosing. Here, the authors employed this technique to evaluate the buffering capacity of skin layers including intact SC, denuded SC and dermis skin samples.

Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.

Water-based, High-UVA Titanium Dioxide Dispersion for Natural UV Protection and Added Formulation Benefits
By: Alice Miles, Michael Hilditch, Robert M. Sayer…
A novel titanium dioxide (TiO2) showing enhanced UVA protection was previously found to be effective as the sole active ingredient in sun care formulations, achieving levels of UVA protection recommended by the European Commission. Here, a water-based dispersion of the same TiO2 particles is described that offers a high level of UVA protection in sun care products with excellent formulation flexibility.

Simple pseudopeptides derived from natural amino acids can be designed and prepared as efficient gelators for a variety of solvents, and with a high potential for biocompatibility. The appropriate selection of structural components, reviewed herein, shows how to produce gels with tailored properties, including high thermal stability.

Recent work indicates that the biomarker progerin, in conjunction with dysfunctioning telomeres, triggers cellular senescence. In response, trifluoroacetyl-tripeptide-2, a synthetic tripeptide, was developed to decrease progerin production, thereby regulating biological mechanisms involved in the aging process and reducing the cosmetic effects of aging, which are explored here.
