Benzylidene-camphors, processes for their preparation and cosmetic compositions containing them

Abstract

Abstract The invention provides compounds which are particularly valuable for use as the active ingredient in sun tan lotions and creams and the like. These compounds have the general formula: <IMAGE> in which Y denotes hydrogen or the radical SO3H or a salt thereof with an organic or inorganic base, and Z denotes the radical -CH2Br or -CHBrBr or a radical Z' which denotes the radical -CH2I, -CH2R, -CHR'R', -CHO or -COOR'', in which R denotes -NR1R2, -N+R1R2R3, -OR4, -OCOR5, -SR6, -CN, -COOR'' or -SSO3Na, in which R1 and R2 independently denote hydrogen, C1-18 alkyl or hydroxyalkyl, or R1 and R2, together with the nitrogen atom to which they are attached, denote a heterocyclic ring, R3 denotes C1-4 alkyl or hydroxyalkyl or sulphonatopropyl, R4 denotes hydrogen, alkyl, polyoxyethylene, aryl which is optionally substituted, menthyl or dialkylaminoalkyl, R5 denotes alkyl, alkenyl, aryl or a 5 or 6 membered heterocyclic ring which is optionally aromatic, and R6 denotes hydrogen, alkyl, carboxyalkyl, aminoalkyl, hydroxyalkyl, aryl or 3-alanyl, R' denotes -OR'4 or -SR'6, in which R'4 and R'6 are as defined under R4 and R6, respectively, except for hydrogen, polyoxyethylene, hydroxyalkyl, 3-alanyl and aryl, and R'' denotes hydrogen or alkyl, such that when R denotes N+R1R2R3, R1 and R2 are not hydrogen and either R3 denotes sulphonatopropyl, or the compound is in the form of a salt with an anion, which is SO4alkyl, SO3aryl, SO3alkyl or halogen or an inorganic or organic acid addition salt thereof when R denotes -NR1R2.
