Avobenzone is a synthetic ultraviolet absorber and an excellent UVA (＞320nm) type ultraviolet absorbent. It can block the full spectrum (320 ～ 400nm) of UVA. As an efficient broad-spectrum oil-soluble UVA filter, it is widely used in broad-spectrum sunscreens. When combined with other UVB sunscreens, it can provide complete UVA and UVB protection, and is used for the prevention of photo-induced skin cancer.

Application information: Sunobel ® 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, Sunobel ® AVB should be properly photo-stabilized. Excellent material for stabilizations is  Sunobel®OCT. Other additional options would be 3-(4-Methylbenzyliden) Camphor or BP-3; Use a chelating  agent like EDTA.  

Known incompatibilities: 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 Sunobel ® AVB and Zinc Oxide can interact to form a complex which may  precipitate out. Sunobel ® AVB is incompatible with Formaldehyde donators which are mainly used as  preservatives.  Packaging: 20 kg/ Carton 25kg/Carton
