The invention relates to a process for preparingnof active substances sun screen counterneritemogenic solar radiation by alkoxylationnanesthesine.nEthoxylation or propoxylation of anesthetic in the presence ofnto a solution of sodium hydroxide in the productnreaction mixture at 150 DEG-165 DEG C. gives a mixturencomplex of N-substituted ethyl-N-substituted aminobenzoates.nThis mixture can be fluidized with propylene glycolnand used as active substance screen in productsnfor the beach because it has 308 ... 312 mm onintensive absorption band, is devoid of toxicity,nit does not irritate the skin, it is slightly soothing, auloplastifiant,nwith the appropriate odor and color, is not soluble innthe water. |
