Methods of treating enveloped viruses with dialkyldialkylammonium halides are disclosed, along with associated pharmaceutical compositions.

Use of dialkyldialkylammonium halide for the preparation of a virucidal medicament intended to be administered by the systemic route

Multilayer elastomer films (multilayer material) comprising at least one continuous layer, carrying an active chemical substance (such as corrosion inhibitors, lubricants or alternatively biocides for medical use), inserted between inert elastomer barrier layers, processes for the preparation and various applications of these films. The multilayer polymeric material comprises at least one layer A composed of a gel which is reversible or non-reversible, as a function of the temperature, and which carries at least one active chemical substance x, and at least two barrier layers E comprising a synthetic elastomer e, the said layers being held together by a polymeric bonding agent y incorporated in at least one of the said layers A or E and/or by an independent bonding layer Z comprising a polymer z and/or by a chemical or physical treatment of at least one of the said layers A or E.

Multilayer material, process of preparation and applications

The invention concerns a porous material, a method for making same and its applications. Said porous material comprises a mixture of cellulose fibres and at least an elastomer and is characterised in that it has a honeycomb structure having cells with a size ranging between 0.1 and 10 mm, a density of the order of 0.03 to 0.1, water absorbing capacity not less than 750%, and water holding capacity after manual wringing less than 100%. The invention is applicable for making in particular sponges and household goods comprising a spongy element such as brushes and squeegees for cleaning surfaces.
