The use of an emulsion for protecting the skin against aggressive chemical agents, wherein this emulsion includes at least one amphoteric chelating agent which includes a complex based on aluminium and on ethylenediaminetetraacetic acid or the trisodium salt thereof, having the general formula [Al(Y)Bn]C′Dc with B being OH−, BO2− or H+, Y being a tetracarboxylate which can be protonated four times to form ethylenediaminetetraacetic acid, n being an integer equal to 0, 1, 2 or 3, D being a counterion, preferably Na+, c being an integer equal to 0, 1, 2 or 3 and c′ being a relative number having the same absolute value as c.
A method for protecting the skin against aggressive chemical agents, comprising applying to the skin an emulsion comprising at least one amphoteric chelating agent that comprises a complex based on aluminum and ethylenediaminetetraacetic acid or its trisodium salt having the general formula [Al(Y)Bn]c′Dc with B representing OH−, BO2−, H+, Y representing a tetracarboxylate, which may be protonated four times to form ethylenediaminetetraacetic acid, n representing an integer equal to 0, 1, 2 or 3, D being a counterion, preferably Na+, c being an integer equal to 0, 1, 2 or 3 and c′ being a relative number having the same absolute value as c.
A method for preventing contact dermatitides, comprising applying to the skin an emulsion comprising at least one amphoteric chelating agent that comprises a complex based on aluminum and ethylenediaminetetraacetic acid or its trisodium salt having the general formula [Al(Y)Bn]c′Dc with B representing OH−, BO2−, Y representing a tetracarboxylate, which may be protonated four times to form ethylenediaminetetraacetic acid, n representing an integer equal to 0, 1, 2 or 3, D being a counterion, preferably Na+, c being an integer equal to 0, 1, 2 or 3 and c′ being a relative number having the same absolute value as c.
