188 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS NEW YORK CHAPTER COSMETic CI•EMISTS of this Chapter were treated to an excellent discussion of a new experimental technique for determining the time varia- tion of interfacial tensions. Dr. John M. Cross, Professor of Pharmaceuti- cal Chemistry at the College of Pharmacy, Rutgers University, introduced the subject at the first meeting of the Chapter, January 4th, at the George Washington Hotel. The usual ring method for measuring the spreading coefficient of cos- metic oils has not given reproducible results, apparently due to a time vari- ation in measuring. Anthony N. Paruta described the bi-phase cell which was constructed for the study and illustrated the concurrent measurement of surface and interfacial tensions and discussed the effect of time on the change in tensions. The oil or lotion in question is floated on the surface of the water in one cell, and the surface tension is measured in the second cell which is connected through a water bridge below the oil-water interface. Some possible applications of this technique were discussed although it was agreed that the method was in its development stage. Dr. Leonard V. Kornblee, Assistant Clinical Professor of Dermatology at New York University, presented an up-to-date review of some of the uses and contra indications of estrogenic, androgenic and corticosteroid hor- mones in dermatology, at the February 1st meeting. Estrogens have no beneficial effect on the sebaceous glands in acne, but the corticosteroids, because of their anti-inflammatory action have been found to be helpful. Hair growth, in certain types of alopecia, can be stimulated by injection of steroid hormones, whereas topical application is ineffective in such cases. Dr. Kornblee pointed out that oral administration often leads to side effects, which are reversible, but that injections have a localized action with many less side effects. This localized action is responsible for the dramatic results often obtained with triam cinalone acetonide injections into psoriatic lesions. During their regular monthly meetings at the George Washington Hotel, Lexington Avenue and 23rd Street, New York City, the cosmetic chemists were acquainted with some of the radioactive and sensitization studies which are being conducted clinically to better understand the action and safety of hormones.
