Abstract: Composition comprises, in a medium, substituted iridoid compounds (I) and/or 2,5-dihydro-furan-2-ol compounds (IA) or their plant extracts, and at least one nucleophilic carbonyl compound, which optionally comprises anions or their mixtures to ensure electrical neutrality of the composition. Composition comprises, in a medium, substituted iridoid compounds of formula (I) and/or 2,5-dihydro-furan-2-ol compounds of formula (IA) or their optical or geometrical isomers, or their mineral or organic acid salts, or solvates, or their plant extracts, where (I) optionally undergo a step comprising replacing the radical R with a hydrogen atom produced by an enzyme, prior to or simultaneously during the coloring of hair, and at least one nucleophilic carbonyl compound of formula (A1-C(=O)-C((R1b) 2)-C(=O)-B1) (II), (III), (IV) or (R25-O-C(=O)-CH 2-CN) (V) or its optical or geometrical isomer, organic or mineral acid salt or solvate, where the compounds (II)-(V) optionally comprise anions or their mixtures to ensure electrical neutrality of the composition, and are also from carbonyl oligomers or polymers comprising polymalonic acids or their esters, polysuccinic acids and/or sulfoacetic acid polymers. R1 : hydroxymethyl, -CO 2R4 or a sugar radical; R4 : H or 1-2C-alkyl; R2 : H, hydroxy or a sugar radical; R3 : H, hydroxy or 1-4C-alkyloxy, where the number of hydroxy groups is = 2; R : a sugar radical, where the sugar radical is a derivative obtained from an aldose or its derivative; n : 1-5; either A1 : A11-[C((R1a) 2)-C((R1a) 2)] n1-, A11a-[C(R1a)=C(R1a)] n1- or A22-O-; and B1 : B11-[C((R1a) 2)-C((R1a) 2)] m1-, B11a-[C(R1a)=C(R1a)] m1- or B22-O-; or A1+B1 : a 5- or 6-membered ring or heterocycle optionally comprising a heteroatom, preferably O, where the ring or heterocycle is optionally fused to a phenyl radical i.e. optionally substituted with at least one CH 3CO-, -COOR66 or -OCOR66; n1 : 0 or 1; m1 : 0 or 1; R1a : H or 1-4C-alkyl; either R1b : H or CH 3CO-, where one of the two radicals R1b represents H; and A11 , B11, A11a, B11a : 6C-aryl (optionally substituted with at least one linear or branched 1-20C-alkyl, hydroxy, -OR11, -OCOR44, -N +>(R55) 3or halo (preferably Cl), where the 6C-aryl is optionally fused to an unsaturated or aromatic 5- or 6-membered heterocycle comprising at least one heteroatom, preferably O), or pyridinyl or pyridinium, where the quaternized nitrogen atom is substituted with 1-4C-alkyl (optionally bearing hydroxy), 1-4C-alkyl; or two radicals R1b : a phenylmethylenyl, where the phenyl radical is optionally substituted with at least one hydroxyl or 1-4C-alkoxy; or R1b+A11a (where n is 1) : a 6-membered hydrocarbon-based ring (optionally substituted with 1-2C-alkyl or hydroxy); R11 : 1-4C-alkyl (optionally substituted with hydroxy) or -Si(R22)(OSi(R33) 3) 3; R22, R33 : 1-4C-alkyl, preferably CH 3; R44 : phenyl radical; R55 : 1-4C-alkyl (optionally bearing at least one hydroxy); R66, R22a : 1-4C-alkyl; either A22, B22 : a linear or branched 1-10C-alkyl (optionally contains one or more unsaturations and optionally substituted with a -Si(R22a) 3), 3-6C-alkenyl, H, alkali metal or alkaline-earth metal or ammonium group; or A22+B22 : 6-membered heterocycle optionally substituted with a 1-2C-alkyl; y : 0-3; D1 : -CR24-, O, -CO- or -C(R24)=C(R24)-; E1 : -CR23a- or O; R23a : H or R23; either R23 : hydroxy or 1-4C-alkyl (optionally substituted with at least one hydroxy); or R23+C+R23 : a fused aryl ring (optionally substituted with at least one 1-4C-alkoxy or a hydroxy); R24 : H or linear or branched 1-4C-alkyl; R25 : linear or branched 1-6C-alkyl (optionally substituted with -SO 3 ->Na +>or -C(NHR26)=NR26a); and R26, R26a : cyclic 4-8C-alkyl. Independent claims are included for: (1) coloring human keratin fibers, preferably hair comprising applying the composition on the fibers; and (2) a multicompartment device comprising a first compartment containing (I) and/or (IA) or their plant extracts, and a second compartment containing (II)-(V), carbonyl oligomers or polymers.
