Titanium Dioxide Particle vs. Sun Protection Performance
By: S. Wiechers, PhD; P. Biehl; C. Luven; M. Maier…
The article compares the performance of titanium dioxide as a UV filter in cosmetic formulations as a function of its primary particle size. It was found that with increasing primary particle size, even below 100 nm, the effectiveness of the inorganic (mineral) UV filter was clearly reduced.

Sun Care Use: Beach Survey
By: Dennis Lott , Florida Suncare Testing Inc.
In September 2012, 101 sun care product users were surveyed on the beach regarding what SPF and product form(s) they were using, among other questions. While 12.2% used SPFs of 15–29, a 58% majority used SPFs of 30–50. Lotions were the favored form, followed by sprays. This article reports the detailed findings from this survey.

Regulatory Review—Titanium Dioxide
By: David C. Steinberg, Steinberg & Associates
This column will discuss titanium dioxide (TiO2). TiO2 is the most frequently used ingredient in cosmetics after water (aqua), fragrance (parfum), methylparaben, propylparaben, glycerin and propylene glycol, according to the U.S. Food and Drug Administration’s (FDA) Voluntary Cosmetic Registration Program.

Influence of Skin Diffuse Reflectance on Sun Damage and Ingredient Efficacy Measurements
By: Olga V. Dueva-Koganov, PhD, Artyom Duev and St…
Current in vitro methods to assess photostability and antioxidant activity do not account for the diffuse reflectance of skin. Described here is an in vitro test that addresses this variable, mimics end-use product conditions and models photodamage processes. The approach is employed to determine the efficacy of an antioxidant from the Camellia sinensis (tea) plant.

Fragrancing Sun Care Products
By: Jill B. Costa, PhD, Bell Flavors and Fragrance…
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.

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.
