Novel Azobenzene Compound to Extend and Reactivate UV Protection

May 1, 2014Jin-Ye Wang, PhD, and Shengyong Geng, Shanghai Jiao Tong University, Shanghai, China

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.
