Abstracts The Annual Scientific Meetings and Seminars of the Society of Cosmetic Chemists are important venues for informing the participants about the state of the art and recent technical advances in the field of Cosmetic Science. To provide broader dissemination of that information, the Publication Committee has decided to publish in the Journal abstracts of the technical presentations made at these Meetings and Seminars.--The Editor. Society of Cosmetic Chemists Annual Scientific Meeting New York, NY, December 10-11, 1981. Application and advantages of an automated data collection system in an antiperspirant testing laboratory Val F. Cotty, Ph.D. and Diana Hess, Bristol-Myers Products, 1350 Liberty Ave., Hillside, NJ 07207. The roles of various electronic devices in a small laboratory are discussed. Previous manual entry of data generated a lot of paperwork and required a great deal of time to communicate information. This system caused increases in costs and a back- log of work. A program was undertaken to imple- ment a more efficient system. A new system was designed to provide instantaneous access to panel participant information and data collection and retrieval. The sequence of system development described demonstrates one way in which a successful automated system can be implemented. Basic aluminum chloride complexes. I. Physi- cal-chemical characterization of their aque- ous solutions John L. Fitzgerald, Ph.D., South Dakota School of Mines and Technology, Rapid City, SD 57701. Detailed studies of concentrated basic aluminum chloride systems of high OH/AI ratio from n = 2.5-2.0 have been carried out using gel filtration chromatography, ferron kinetic studies, and 27A1 NMR spectroscopy. All basic aluminum polymer solutions examined were observed to be polydis- perse with varying concentrations of discrete poly- meric, oligomeric and monomeric species. Gel filtration studies reveal species molecular weight ranges from that of the monomeric A13+ ion to 6800 daltons. Analysis of experimental chromato- grams and simulated gel filtration data have allowed the calculation of MWw, MWn values and polydispersity indexes for three basic aluminum systems of n = 2.5, 2.25 and 2.0. Molecular weight values decrease with basicity, as expected. Compar- ison of gel filtration results with ferron data, 27A1 NMR measurements and other polymer characteri- zation results is presented. Concentrated basic aluminum chloride systems are chemically distinct in comparison with the Al•cmer complex x-rayed by Johansson. The complexes appear to be in a state of pseudo-equilibrium at high concentration and undergo complex chemical changes upon 39
