Compositions comprising organometallic compounds formed by hydrolysis and condensation of metal alkoxides, complexes or halides. Compositions comprising organometallic compounds formed by partial or complete hydrolysis and partial or complete condensation of metal alkoxides of formula (1a)-(1d), metal complexes of formula (2a)-(2d), metal halides of formula (3a)-(3d) or metal complexes of formula (4a)-(4d): M-(OR1)n R-M-(OR1)n-1 (R1O)n-1-M-R''-M'-(OR1)n-1 (1a) (1b) (1c) RR'-M-(OR1)n-2 (1d) M-(OR1)n-x(X)x R-M (OR1)n-1-x(X)x (2a) (2b) (X)x (R1O)n-1-x M-R''-M'-(OR1)n-1-x (X)x RR'-M-(OR1)n-x-2 (X)x (2c) (2d) M-(Z)n R-M-(Z)n-1 (Z)n-1-M-R''-M'-(Z)n-1 (3a) (3b) (3c) RR'-M-(Z)n-2 (3d) M-(Z)n-x (X)x R-M (Z)n-1-x (X)x (4a) (4b) (X)x (Z)n-1-x M-R''-M'-(Z)n-1-x (X)x RR'-M-(Z)n-x-2 (X)x (4c) (4d) M, M' = Group Ib-VIIb metals, Group VIII metals, lanthanides, Al, Si, B, Sn, alkali metals or alkaline earth metals; n = the valence of the metal; R1 = (un)saturated linear or branched 1-30C hydrocarbyl optionally interrupted or substituted with 1-20 heteroatoms selected from O, N, S and P; R, R' = H or (un)saturated linear, branched or cyclic 1-30C hydrocarbyl optionally interrupted or substituted with 1-20 heteroatoms selected from O, N, S and P and/or substituted with cosmetically active groups; R'' = O, NR<2>, S or (un)saturated linear, branched or cyclic 1-30C hydrocarbylene optionally interrupted or substituted with 1-20 heteroatoms selected from O, N, S and P and/or substituted with cosmetically active groups; R<2> = (un)saturated linear, branched or cyclic 1-30C hydrocarbyl; X = an N-, P-, S- and/or O-containing ligand optionally substituted with cosmetically active groups; x = the number of atoms that can bond to the central metal atom; and Z = halogen. |
