An organic UV filter providing a very good SPF boost and a significant contribution to the UVA protection

PARSOL® 1789 (INCI: Butyl Methoxydibenzoylmethane) is a very strong and efficient UVA absorber for sunscreen and other skin care formulations. It enables broadband protection when combined with effective UVB filters and can also contribute to SPF. PARSOL® 1789 is an oil-soluble, white to pale yellow powder that must be completely solubilized in formulations. It works with a range of solubilizers including the UVB filters PARSOL® 340, PARSOL® EHS, PARSOL® MCX, and many emollients. PARSOL® 1789 should be photostabilized, for example with PARSOL® 340. This UV filter is approved worldwide.
