Envisioning SPF
By: Rachel Grabenhofer, Cosmetics & Toiletries mag…
The sun care industry faces several challenges, including testing and measuring SPF, questions over the safety of nanotechnology, sunscreen stability, broad-spectrum protection, and inconsistent regulations for allowed UV filters and their combinations. Some of these challenges have plagued product developers for years, thus the industry has had time to develop the means to meet some of them. Recent work in these areas is the primary focus of this issue of C&T magazine.

Controlling Hydroxyl Radical Formulation in TiO2 Sunscreens
By: Nai-Fang Chang and Chang-Chin Kwan, Providence…
Titanium dioxide (TiO2) is an effective sunscreen agent but its rutile form may produce hydroxyl radicals upon exposure to sunlight. Thus, the authors use salicylic acid as a capture agent to examine the development of free radicals in solutions or creams containing TiO2. They also explain how the choice of emulsion may reduce free radical generation.

Micron-sized Zinc Oxide Dispersion for Transparent High SPF Formula
By: Paul McCormick, PhD, Antaria Ltd.; Robert Flet…
Regulatory bodies require quantifiable, photostable UVA protection for sunscreens and while zinc oxide provides an effective option, historically, its white appearance on skin has limited its acceptance. Therefore, in the present article the authors explore a micron-sized zinc oxide dispersion technology to enable the formulation of transparent yet full spectrum sunscreen formulas.

Singlet Quenching Proves Faster is Better for Photostability
By: Craig Bonda and Anna Pavlovic, The HallStar Co…
The faster a photostabilizer works, the fewer opportunities for destructive chemical reactions. Here, the author describes a new photostabilizer, ethylhexyl methoxycrylene, which acts by quenching the singlet excited state of UV filters. The data shows how this material sets a new standard for the photostabilization of avobenzone, even in the presence of octyl methoxycinnamate.

Study of Twins Correlates Aging with Genetics
While up to 40% of aging-related changes in skin are due to non-genetic factors, a recent study found a high correlation between the photodamage scores among both monozygotic (identical) and dizygotic (fraternal) twins.
