Abstract
Aqueous emulsions which contain the fatty acid esters of N-methyl-N,N,N-trihydroxyethyl ammonium methyl sulfate as cationic tensides are suitable as fabric softeners. These fabric softener emulsions have the disadvantage, however, that emulsions with high concentrations can be handled only by means of dispersion agents. Therefore, an aqueous emulsion of fatty acid ester of N-methyl-N,N,N-trihydroxyethyl ammonium methyl sulfate is proposed which is stable in storage, and demonstrates an active substance content of more than 15% at a viscosity below 100 mPa.s at 25.degree. C. This emulsion can be used without any additional emulsifier. The emulsion according to the invention has quaternary ammonium compounds with 1.1 to 1.7 fatty acid groups, as a mean value.
