Abstract: AQUEOUS BASED COSMETIC LOTIONS FOR SKIN CARE AND SKIN PROTECTION MAY BE FORMULATED TO CONTAIN HIGH LEVELS OF AN OILY EFFECT AGENT, SUCH AS AN EMOLLIENT, WITHOUT IMPARTING A GREASY OR OILY FEEL TO THE TOUCH AFTER APPLYING AND DRYING SAME BY THE INCLUSION IN THE LOTION OF AN EMULSION (PATEX) OF A WATER INSOLUBLE, ORGANO SOLUBLE, FILM-FORMING VINYL POLYMER AND A COSMETICALLY SUITABLE EMULSIFYING AGENT. THE EFFECT AGENT MUST BE A NON-SOLVENT AND A NON-PLASTICIZER FOR THE VINYL POLYMER. CERTAIN DESIRABLE INGREDIENTS SUCH AS HUMECTANTS, THICKENERS, ETC. MAY BE OPTIONALLY ADDED TO THE LOTION.

Abstract: N-Benzylically substituted aziridines are conventionally prepared by reacting a benzyl halide with aziridine (or other non-N-substituted aziridine) in the presence of an acid acceptor. Product yields are considerably improved by conducting the above process in a liquid aromatic hydrocarbon reaction medium. E.g., N-benzylaziridine is prepared in excellent yields by reacting benzyl chloride with aziridine in the presence of powdered KOH and benzene.

Abstract translation: N-苄基取代的氮丙啶通常在酸受体存在下使苄基卤与氮丙啶（或其它非N-取代的氮丙啶）反应制备。 通过在液体芳族烃反应介质中进行上述方法，产物产率显着提高。 例如，通过苄基氯与氮丙啶在粉末状KOH​​和苯的存在下反应制得N-苄基氮丙啶。
