Abstract: Process of capillary treatment hair, preferably damaged hair, comprises applying, on the hair, a cosmetic composition comprising at least one dithiolane compound (I) or its salts, chelates, solvates or optical isomers. Process of capillary treatment of hair, preferably damaged hair, comprises applying, on the hair, a cosmetic composition comprising at least one dithiolane compound of formula (I) or its salts, chelates, solvates or optical isomers. m, n : 0-2; Y1 : O, NR1 or S, preferably O, NH or N(CH 3); R1 : H, optionally saturated 1-32C hydrocarbon (optionally comprising one or more heteroatoms of O, NR1a or S) or phenyl optionally substituted by one or more OH and/or 1-6C alkoxy; R1a : H or 1-6C alkyl; R : (i) optionally saturated 8-300C hydrocarbon group (optionally comprising one or more heteroatoms of O, NR1a or S), (ii) phenyl optionally substituted by one or more OH and/or 1-8C alkoxy, or (iii) optionally saturated 8-30C hydrocarbon group, substituted by phenyl itself optionally substituted by one or more OH and/or 1-8C alkoxy, where R is optionally further substituted by one or more substituents of OR2, SR2, NR2R3, or COOR2; R2 : H, saturated 1-5C linear or 3-5C branched hydrocarbon group, 2-5C unsaturated hydrocarbon group, or phenyl; and R3 : H, saturated linear 1-5C or 3-5C branched hydrocarbon group, 2-5C unsaturated hydrocarbon group, phenyl or acetyl group. Provided that when Y1 is NR1, R and R1 may also form a ring comprising pyrrolidine, pyrroline, piperidine, piperazine, morpholine, thiomorpholine, or azepine. Independent claims are included for: (1) cosmetic composition comprising (I) in a medium; and (2) the dithiolane compound (I) (where R is R2a). R2a : (i) optionally saturated 21-300C hydrocarbon group (optionally comprising one or more heteroatoms of O, NR1a or S), (ii) saturated 9-30C alkyl hydrocarbon substituted by phenyl itself optionally substituted by one or more OH and/or 1-8C alkoxy, where (i) and (ii) are further substituted by one or more substituents of OR2, SR2, NR2R3, or COOR2, or (iii) optionally saturated 8-20C hydrocarbon group, optionally comprising one or more heteroatoms of O, NR1a or S; Y1 : O, NR1 or S, preferably O, NH or N(CH 3); R1 : H, optionally saturated 1-32C hydrocarbon (optionally comprising one or more heteroatoms of O, NR1a or S) or phenyl optionally substituted by one or more OH and/or 1-6C alkoxy; and R1a : H or 1-6C alkyl. Provided that: when R2a is (i) or (ii), then Y1 is O, NR1 or S, preferably O, NH or N(CH 3), R1 is H, optionally saturated 1-32C hydrocarbon (optionally comprising one or more heteroatoms of O, NR1a or S) or phenyl optionally substituted by one or more OH and/or 1-6C alkoxy, and R1a is H or 1-6C alkyl; or when R2a is optionally saturated 8-20C hydrocarbon group, optionally comprising one or more heteroatoms of O, NR1a or S, then R1a is H or 1-6C alkyl, Y1 is NR1 and R1 is optionally saturated 21-32C hydrocarbon group optionally comprising one or more heteroatom of O, NR1a or S or R1 is optionally saturated 8-20C hydrocarbon group optionally comprising one or more heteroatom of O, NR1a or S, and R1a is H or 1-6C alkyl (when R1 is R2a).
