Abstract:
A method of protecting and/or strengthening a keratin material comprising applying to said keratin material a composition comprising at least one organometallic compound obtained from at least one metal alkoxideRâ€”Mâ€”(OR1)nâˆ’1â€ƒâ€ƒ(Ib) wherein:M denotes a metal atom chosen from the transition metals of groups Ib to VIIb of the Periodic Table, group VIII of the Periodic Table, the lanthanide group of the Periodic Table, aluminum, silicon, boron, tin, magnesium, alkali metals and alkaline-earth metals; n denotes the valency of the metal; R1, which may be identical or different, is chosen from linear and branched, saturated and unsaturated hydrocarbon-based radicals containing 1 to 30 carbon atoms, R is chosen from hydrogen, and linear, branched and cyclic, saturated and unsaturated C1-30 hydrocarbon-based radicals; and wherein said composition is applied to said keratin material in an amount effective to obtain at least one of harder nails, stronger nails, less brittle nails, nails which no longer split, and nails which no longer crack.
