j. Soc. Cosmet. Chem., 39, 77-80 (January/February 1988) 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 Publi- cations Committee has decided to publish abstracts of the technical presentations made at these Meetings and Seminar in theJournaL--The Editor. Society of Cosmetic Chemists Annual Seminar May 5-6, 1988 Hyatt Regency, Minneapolis, Minnesota Program arranged by the Society's Committee on Scientific Affairs Morton Pader, Ph.D., Chairman, 1988 SESSION A MOLECULAR DESIGN OF INGREDIENTS FOR PERSONAL CARE PRODUCTS carbon compatibility further. Comparative data on some acrylate resins are presented. New polymers for hair care products F. Vogel, Ph.D., and F. Frosch, Ph.D., BASF Ak- tiengesellschaft, MEF/D-H 201, 6700 Ludwig- shaferdRh., West Germany Recent market trends require hair care resins with improved hold characteristics. New resins which fill these market needs are discussed for aqueous and alcoholic applications. In water-soluble resins, vari- ation of the molecular weight of polyquaternium- 16 leads to the required hardness maintaining impor- tant other product properties, and variation of the monomer composition correlates directly to condi- tioning efficacy. In the case of alcohol-soluble resins, the introduction of a third monomer into traditional copolymers results in a remarkable change of properties. The influence of the variation of monomer ratios upon the hydrocarbon tolerance of vinylpyrrolidone terpolymers and other polymer systems was investigated and results are presented in the case of vinylprrolidone/vinylacetate/vinylpro- pionate terpolymers, an optimal ratio was found at 30/40/30. The introduction of other functional groups, i.e., amides, increases hardness and hydro- Pyrrolidone-based surfactants Robert B. Login, Ph.D., GAF, 137 Page Dr., Oakland, NJ 07436 Pyrrolidone, a highly polar hydrophilic lactam structure, can be incorporated into a variety of sur- factant molecules to afford auxilliaries of unique in- terest to formulatots of personal care products. Pyr- rolidone-based surfactants can contribute condi- tioning, complexing, thickening, and foam stabilizing in a wide variety of end-use applications. In addition, the extensive toxicity studies con- ducted so far indicate a high level of safety. Surfa- done TM LP (N-Alkylpyrrolidones) are commerical examples of this class of surfactant.
