Claim 26:
27. A method for preparing a topical composition as defined according to claim 1, wherein said method comprises
(i) the preparation of a buffering solution (BS) comprising a buffering agent having an acid pH,
(ii) the preparation of a solution of a metal complex (SC) comprising a metal oxide salt,
(iii) the preparation of a first initial solution (Si1) comprising hydrogen peroxide,
(iv) the preparation of a second initial solution (Si2) by mixing the BS solution with the Si1 solution,
(v) the preparation of a solution (S1) comprising a peroxo-metal compound by mixing the SC solution with the Si2 solution,
(vi) the preparation of a solution S2 by adjusting the pH of the solution S1 with a base, the pH of the solution S2 being more basic than the pH of the solution BS,
(vii) the addition to the solution S2 of one or several chelating agents,
(viii) the optional adjustment of the pH of the solution resulting from step (vii),
(ix) the optional adjustment of the volume of the solution resulting from step (vii) or step (viii), and
(x) the obtaining of a mixture or of a composition as defined according to claim 1 resulting from step (vii) or optional step (viii) or optional step (ix).
