396 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS a number of years, studying the usefulness of certain trace materials, vita- mins and several therapeutic agents. The injurious effect of certain un- saturated lipoids was mentioned. J. Morelie (France) reviewed sulfur containing chemical substances and their application in cosmetics. He tried to tie together the presence of sul- fur with certain biochemical reactions. The presence of sulfur in biochem- ical materials was discussed from the viewpoint of its need by the body. After lunch Dr. H. C. Friederich (Germany) discussed a number of cutaneous reactions resulting from the use of cosmetics. Dr. J. Cotte (France) then gave a review of his study on the subject of diffusion of medicinal materials from various types of novel cream and ointment bases. Dr. A. Zenisek (Czechoslovakia) gave an additional paper on his long study of urocanic acid, which is excreted in the perspiration, and its effect on skin irradiation in sunshine. He pointed out that a certain amount of urocanic acid is necessary to be able to get a satisfactory sun tan. Samuel Cohen (U.S.A.) discussed the subject of dimethylhydantoin and its derivatives as novel cosmetic materials. He traced the chemistry of this substance and pointed out that it had application in certain types of hair sprays, among other cosmetics. Dr. J. Stiras (France) then gave a r•sum• of a long study on the effect of soaps on perfumes or to put it differently, the stability of perfume in soap. Tables of data were presented to illustrate the text. Dr. Paolo Rovesti (Italy) discussed the subject of biocatalyzers for the skin as derived from vegetable juices. This has been a specialty with the speaker for a number of years. The final paper was given by Professor J. Lecourt (France) on the use of Royal Jelly in dermatology and cosmetics. This entire group of papers is to be published in a new French journal en- titled, Cosmetologie, the first issue of which has gone to press at the time of this report. In Geneva the recently formed Swiss Society of Cosmetic Chemists welcomed the U.S. delegation on August 1st. Two technical meetings were held with papers given by six Swiss scientists at the first meeting on August 2nd at the Aula of the University of Geneva. After an introduction by the president of the Swiss Society, Kurt J. Pfeiffer, a responding com- mentary was made by President S. J. Strianse of the U.S. Society. The meeting was then turned over to Dr. Donald Powers and Edward Morrish of the U.S. Society who introduced the speakers on the program. Dr. N. Avalle gave the first paper on the subject of Aleurone and Bi- aleurone, the most recent discovery and its applications to cosmetics. Dr. Avalle discussed the composition of aleurones and their possible biochem- ical relationship to skin health.
