INTRODUCTION
The word “natural” has evolved, over the past several years, to mean the exclu-
sive use of plant-based ingredients to create a finished product. Consumers now
seek out products that claim to be “natural” or “all-natural,” even though the FDA
has not issued regulations to define the term “natural” when applied to cosmetics.
Just recently, C&T Magazine reported, “new ingredients-vitamin C and natur-
als such as aloe vera and chamomile are also finding their way into sun product
formulations to make them more attractive to customers” (1). The sunscreen
development process, therefore, must not stop at adding a few natural ingredients
to an otherwise traditional product. It must start with a re-examination of all the
components that make up a sunscreen, with an eye to maximizing the efficacy and
sustainability of each. Then, and only then, can a formulator put together a
sunscreen product that is truly “natural.”
