Today, zinc oxide is not a treatment for skin cancer, but used in a variety of wound healing and sunscreen formulations. It is the only sunscreen ingredient that is also recognized by the U.S. Food and Drug Administration (FDA) as a Category I Skin Protectant and is recommended for use on compromised skin.

Two azobenzene compounds were synthesized and combined in liposomal membranes. Their physico-chemical properties and biocompatibility were evaluated. The safer one was chosen, and its protective function for UVA and UVB were tested in vitro and in vivo. This azobenzene liposomal formulation provided good efficacy with longer shelf life, which could be utilized as a novel kind of repeated UV absorber.

While TiO2 is often incorporated as a colorant and an opacifier in cosmetics and personal care products, its most important applications are as a sunscreen active and as a component of specialty pigments for color cosmetics.

High energy visible (HEV) light recently has been suspected of causing as much damage as UVA and UVB combined. Thus, the present paper describes a fractionated melanin tailored to absorb light in the visibile 400–500 nm range. In addition, because the material exhibits color, the authors focus on formulation techniques to incorporate it into semi-solid formulations.

The production of a range of titanium dioxide-based dispersions is explored to provide enhanced UVA protection, in comparison with ultrafine titanium dioxide. Formulations containing these dispersions as the only active are shown to achieve a UVA protection factor that is 1/3 of the labeled SPF value, thus meeting European Commission recommendations.

Silicon microspheres are described as UV, visible and infrared (IR) radiation filters. Parameters of these spheres including shape, smoothness, refractive index and size are examined for their potential benefits in cosmetic formulations. Finally, the ability of the spheres to block IR radiation is evaluated for thermo-regulatory effects.

In 1876, Charles Darwin observed the secretion of yellow matter from the rootlets of ivy. Little was known about the material until 2008, when Mingjun Zhang, PhD, an associate professor of biomedical engineering at the University of Tennessee, and his research team found nanoparticles in the yellow matter.

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.

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.
