| abstract |
The invention relates to an oxidation dyeing composition for keratin fibers, in particular the hair, comprising as oxidation base at least one amino acid derivative of formula: (CF DRAWING IN BOPI) where n = 0-11 , R represents H, amino, C1 -C6 alkyl or is chosen from (CF DRAWING IN BOPI) - (CH2) n '-SR' -CH2 OH -CHOH-R '- (CH2) n' -NH-X and (CH2) n '-NH 2 R' represents C1 -C6 alkyl, n '= 1-6 and X is an aromatic group with one or two rings, which may contain one or more heteroatoms chosen from S, N or O, or minimum substituted by -NHR "or by -OH, R" denoting H, C1 -C6 alkyl, or their addition salts with an acid. The invention also relates to the new compounds of formula (I) above, excluding n = O, R = H and X = 4-aminophenyl, 4-hydroxy-3-pyridyl and 2,6-diamino -4-pyrimidyl and n = 0, R = CH2 OH and X = 4-amino-6-methyl -2-pyrimidyl. |
