Abstract: Method of hydrodechlorinating nuclear-chlorinated o-xylenes and recovering o-xylene, forming hydrogen chloride, the nuclear-chlorinated o-xylenes being hydrogenated in the gas phase at a noble-metal-containing catalyst at a temperature in the range from 220 to 360° C. The catalyst preferably comprises palladium or platinum, in particular supported palladium or platinum. The nuclear-chlorinated o-xylenes can be used individually or as mixtures.

Abstract: The invention relates to cosmetic, dermatological, and pharmaceutical products containing an electrolyte. The products are obtained by free-radical copolymerization of A) acryloyldimethyltaurine and/or acryloyldimethyltaurates, and B) optionally, one or more further olefinically unsaturated, noncationic comonomers, C) optionally, one or more olefinically unsaturated, cationic comonomers, D) optionally, one or more silicon-containing component(s), E) optionally, one or more fluorine-containing component(s), F) optionally, one or more macromonomers, G) optionally, the copolymerization taking place in the presence of at least one polymeric additive, H) with the proviso that component A) is copolymerized with at least one component selected from one of the groups D) to G).
