Avobenzone/AVB

Multivalent metal cations should be avoided as they may form discolo-rations (E.g. Fe) or crystals due to lower solubility of the complexes (e.g.Al and Mg). Al coated Titanium Dioxides may lead to crystals. The combination of Avobenzone/AVB and Zinc Oxide can interact to form a complex which may precipitate out. Avobenzone/AVB is incompatible with formaldehyde donators which are mainly used as preservatives.

Avobenzone/AVB Application:

Avobenzone/AVB is oil soluble, effective UVA absorber. Adequate solubility in the formulation must be ensured in order to avoid recrystallization during storage. To maximize utilization and high performance, AVB should be properly photo-stabilized. Excellent material for stabilizations is OCT. Other additional options would be 3-(4-Methylbenzyliden) Camphor or BP-3; Use a chelating agent like EDTA.
