Abstract (en)
[origin: WO0050003A1] The invention relates to a hydrophobic, rheologically active agent based on clays and/or clay minerals which are capable of ion-exchange. The inventive agent contains N,N-di(acyloxy-2-ethyl)-N-hydroxy-2-ethyl-N-methylammonium methosulfates, methylammonium methophosphates, and/or methylammonium dimethophosphates as hydrophobing cations. Hydrophobic thixotropic agents are produced when using bentonites and these cations. Said thixotropic agents are free from chloride and are well-suited for use in technical, cosmetic and medical-pharmaceutical products.
