Abstract of the Disclosure Stable concentrated aqueous solutions of glycidyltrimethyl- ammonium chloride are provided which contain the monohydrate of glycidyl- trimethylammonium chloride in a concentration of 90 % to saturation, said solutions after dilution with water to a content of 25 % glycidyltimethyl- ammonium chloride showing a pH of less than 12.5. Furthermore a process is provided for preparing stable concentrated solutions of glycidyltrimethyl- ammonium chloride, wherein anhydrous glycidyltrimethylammonium chloride is mixed with an excess of water over the amount necessary for forming the desired solution, whereafter the excess of water is evaporated under reduced pressure. Also the invention provides the monohydrate of glycidyl- trimethylammonium chloride as a novel substance.
