Butyl Methoxydibenzoylmethane can also be used in sunscreen preparations where an adequate concentration of both filters gives rise to excellent sun protection by blocking UV-A/UV-B radiations. It provides broad-spectrum protection for the skin and is widely used in sun care preparations.

In addition, Butyl Methoxydibenzoylmethane is used for the formulation of protective hair care preparations. In some cases, it is used as a photo-antioxidant to protect products from photo-oxidation.

UVA radiation (wavelengths between 320nm - 400nm) penetrates down to the dermal layers of the skin. It stimulates tanning and pigmentation but relates also to skin aging.

Furthermore, UV-A may act in an indirect way by creating free radicals and reactive oxygen species. In consequence, an efficient sunscreen should not only prevent sunburn (UV-B rays) but also minimize the accumulation of all radiation-induced damage in the skin which eventually enhances the risk of fatal alterations like skin aging.

So sun care or daily care products should not only contain a UV-B filter but also a very important part add-on of UV-A protection like Butyl Methoxydibenzoylmethane to complete high and safe prevention of skin damage.
