Abstract: A method of preventing contact allergies includes using 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 device, a part of which includes the amphoteric chelating agent, is also described.

Abstract: 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.

Abstract: Individual portable device (1) for eye bath, comprising a receptacle (5) with narrow neck (4) enclosing a sterile liquid for eye bath and an eye cup (2) provided with a sleeve interlocked on the neck; an elastically deformable and heat-stable seal (6) has an at least L-shaped section and rests on the rim (7) of the neck of the receptacle; the skirt (6a) defining the large leg of the L is clamped between the sleeve of the eye cup and the neck of the receptacle; thus the eye cup (2) is secured to the receptacle (5) in a leaktight manner regardless of the deformations undergone by the neck of the receptacle and the sleeve of the eye cup during heat sterilization treatments.

Abstract: The invention relates to a powder spreader device including a sealed tank (1) with a tapered bottom wall (5), a vessel (2) containing a pressurised spray gas connected to the tank (1) via a feed line (27), control means (20) connected to the vessel (1), and a powder dispensing nozzle (10) connected to the tank, wherein the elongate nozzle (10) includes at least two pressure relief stages (11, 12) for breaking up the dispensed powder jet and forming a uniform and homogenous jet with a relatively low flow rate.

Abstract: A tank for a sterile, portable, self-contained shower having an elongated tank body which has an end opening and containing a washing liquid within a single sterile pocket and which is sealingly connected to an outlet opening of the tank and including a carriage with a propulsive compressed gas which is releasable outside of the cartridge. The sterile pocket is elongated with a generally circular cross section and which has a length preferably several times longer than the length of the elongated tank body. The sterile pocket extends in a zig-zag pattern inside of the tank. A tube extends inside of the sterile pocket over a substantial portion of its length and is connected with an outlet opening from the pocket which connects with the outlet opening of the tank.
