Abstract:
The invention relates to compounds and to the cosmetically acceptable salts thereof, which correspond to general formula (I), wherein: R1 represents H, —C(O)—R6, —SO2—R6 or —C(O)—XR6; R2 and R4, independent of one another, represent (CH2)n—NH2 or (CH2)3—NHC(NH)NH2; n equals 1 4; R3 represents linear or branched C1-C4 alkyl that is optionally substituted by hydroxy; R5 and R6, independent of one another, represent hydrogen, optionally substituted (C1-C24) alkyl, optionally substituted C2-C24 alkenyl, optionally substituted phenyl, optionally substituted phenyl-C1-C4 alkyl or 9-fluorenyl-methyl; X represents oxygen (—O—) or —NH—; or XR5 with X═O also represents the esters of a-tocopherol, tocotrienol or retinol, with the provision that R1 and R5 do not represent hydrogen and X does not represent oxygen at the same time. The invention also relates to the production of the compounds of general formula (I) and to a cosmetically active composition that contains at least one compound of formula (I).
