Biobased surfactant

The present invention relates to a compound of the general formula (I), (II) and (III), more specifically of formula (Ia), (Ib), (Ic)wherein R11 and R12 or R21 and R22 or R31 and R32 are both hydrogen or form together with CHR50 a cyclic moiety or one of R11 and R12 or R21 and R22 or R31 and R32 is hydrogen and the other is - CH2R70 and/or wherein R13 and R14 or R23 and R24 or R33 and R34 are both hydrogen or form together with CHR60 a cyclic moiety, R50 and R60 are different form each other and are selected from the group consisting of -R70, -ZR70, -Z-OH, -Z-NH2, -Z-SH, -Z-OC(O)R70, -OC(O)R70, -COOH, -C(O)NH2, -C(O)NH-R70, -C(O)N-(R70)2, -COOR70, -Z-COOH, -Z-C(O)NH-R70, -Z-C(O)NH2, -Z-C(O)N-(R70)2, - Z-COOR70, -CH(COOH)2, -CH(COOR70)2, and -Z-SO3, wherein R70 is a linear or branched C1 to C20 alkyl, (C1 to C10)-alkyloxy-(C1 to C10)-alkyl, C2 to C10 alkenyl, C6 to C12 aryl, C3 to C10 cycloalkyl, cycloalkylalkyl and cycloalkylalkenyl, wherein Z is a linear or branched C1 to C10 alkyl, linear or branched C3 to C10 cycloalkyl, cycloalkylalkyl and cycloalkylalkenyl, a linear or branched C6 to C10 aryl or a (C1 to C10)-alkyloxy-(C1 to C10)-alkyl, with the proviso that not all of R11, R12, R13 and R14 or R21, R22, R23 and R24 or R31, R32, R33 and R34 are hydrogen and if one of R11 and R12 or R21 and R22 or R31 and R32 is hydrogen and the other is -CH2R70, R13 and R14 or R23 and R24 or R33 and R34 form together with -CHR60 a cyclic moiety, wherein R60 is R70.Those compounds are useful as as biobased surfactants.
