Overview
Benzophenone-5
Benzophenone-5 is the monosodium sulfonate salt within Sigmak’s benzophenone-class UV filter offering, used where water-compatible UV-filter chemistry is required.
A sulfonated benzophenone chromophore absorbs ultraviolet radiation; the ionic sulfonate group gives improved water compatibility versus non-sulfonated benzophenone filters.
