The present paper evaluates the effects of solvent systems on the in vivo SPFs of sunscreen formulations. Formulations incorporating identical active systems were prepared using traditional solvent systems and varying concentrations of sorbeth 2 hexaoleate, a new ester having both polar and nonpolar segments. Results indicate the ester enhances SPF in a dose-dependent manner.

In the present article, sunscreens containing the antioxidants vitamin E and diethylhexyl syringylidene malonate were tested for their efficacy in preventing UV-induced reactive oxygen species in the lower stratum corneum. The addition of the antioxidants was found to significantly improve the ability of low to high SPF sunscreens to attenuate ROS formation in UV-exposed skin.

What are the biggest challenges in sun care formulating? I asked a few colleagues, and they answered: achieving what marketing wants while complying with regulations and making sunscreens esthetically pleasing (so consumers will use them); and the lack of international harmonization in UV filters, UVA testing and labeling. These issues are not new, so why are they not yet resolved? Perhaps because regulations and consumer demand are moving targets, which are difficult to hit.

This article reviews the mechanisms of ultraviolet radiation insult to skin and explains the formulation of sunscreens to protect against this damage. Further, since the efficacy of combinations of UV filters will vary with formulation base, the formula vehicle and form are discussed, as well as an overview given of typical sunscreen efficacy tests performed prior to production.
