  • sulfotriglycerides are understood to mean the sulfonation products of triglycerides of saturated fatty acids with 8 to 22 carbon atoms.
  • the mixtures according to the invention are notable for good moisturizing properties, which are subjectively experienced by a pleasant feeling on the skin. In contrast to conventional mixtures, no additional moisturizing component is required to achieve this skin feeling. In addition, the mixtures according to the invention are notable for good foaming behavior.
  • Sulfotriglycerides are prepared in a manner known per se by sulfonating the corresponding saturated fatty acid triglycerides.
