NEW SULFONAMIDES DERIVED FROM 3-BENZYLIDENE CAMPHOR AND THEIR APPLICATION AS UV FILTERS, ESPECIALLY IN COSMETIC COMPOSITIONS. THE COMPOUNDS OF THE INVENTION HAVE THE FORMULA: (CF DRAWING IN BOPI) IN WHICH XH OR Y; X IS HYDROGEN, HALOGEN, ALKYL OR C-C OR Y OR Z ALCOHOL; X IS H, HALOGEN, ALKYL, OR C-C OR Y OR Z ALCOXY; OR X AND X TOGETHER FORM A 1 OR 2 C ALKYLIDENEDIOXY; Y IS (CF DRAWING IN BOPI) OR R IS H, ALKYL OR HYDROXYALKYLEEN C-C; R IS H, ALKYL OR ALKENYL, CYCLOALKYL, ARYL OR ARALKYL, R AND R MAY NOT BE HYDROGEN TOGETHER; Z DESIGNATED (CF DRAWING IN BOPI) Z OR Z OR Z-CC-R OR R IS H, -CN OR -COR; R EST -COR, R AND R BEING ALCOXY OR ALKYLAMINO IN CC, PROVIDED THAT ONE OF THE SYMBOLS X, X, X IS DIFFERENT FROM THE TWO OTHERS AND THAT WHEN XH, X AND X ARE DIFFERENT FROM ONE TO THEM AND CANNOT TAKE THE Z AND Z VALUES, ONE OF THE TWO MUST BE Y OR Z; WHEN X HAS THE Y VALUE, X AND X ARE DIFFERENT FROM Y AND CANNOT TAKE THE Z, Z OR Z VALUE AT THE SAME TIME. THESE COMPOUNDS ARE USEFUL AS SOLAR FILTERS IN COSMETIC COMPOSITIONS. |
