Application of nanostructural modification of polymer surface by molecular imprinting with proteins towards increased selective adsorption Ewa NAWROCKA, Barbara WANDELT - Faculty of Chemistry, Department of Molecular Physics, Technical University of Łódź Please cited as: CHEMIK 2011, 65, 2, 98-104 We report here molecular imprinting at a polymeric surface using protein as a template. That was to obtain sensing material being selective in adsorption of protein from environment. Two similar structure proteins: ? - lactalbumin and ovalbumin differing in molecular mass and size of the...Read more

Treatment of cosmetic wastewater using physicochemical and chemical methods Jan BOGACKI, Jeremi NAUMCZYK, Piotr MARCINOWSKI, Małgorzata KUCHARSKA -Division of Informatics and Environment Quality Research, Warsaw University of Technology, Warsaw Please cited as: CHEMIK 2011, 65, 2, 94-97 The paper is a review of literature on the effectiveness of physicochemical and chemical methods of cosmetic wastewater treatment. These methods may be the principle level of treatment, or be a stage prior to biological treatment. The result obtained by different authors is difficult to compare because...Read more
Analytical methods for identification and determination of some cosmetics ingredients Katarzyna Jagodzińska, Agnieszka Feliczak-Guzik, Izabela Nowak - Adam Mickiewicz University, Poznań Please cited as: CHEMIK 2011, 65, 2, 88-93 Analytical techniques, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC) are very useful tools for evaluation of the quality of cosmetics. In recent years a powerful analytical device has become a combination of GC and HPLC with mass spectrometry (GC-MS and HPLC-MS). These methods are fast, give highly selective detection and quantification and...Read more
Synthesis and characterization of metallic oxides with potential use in cosmetic products Agata WAWRZYŃCZAK, Izabela NOWAK - Faculty of Chemistry, Adam Mickiewicz University, Poznań Please cited as: CHEMIK 2011, 65, 2, 82-87 The aim of the study was to synthesize and characterize some metallic oxides (TiO2, ZrO2, ZnO, CeO2) with potential UV protection properties, as well as oxides that can be used as pigments in cosmetic formulations, namely Fe2O3 and Fe2O3/SiO2 systems. Physicochemical properties of the synthesized oxides, especially coloration, absorbing power in the...Read more
Application of artificial skin models to investigate innovative cosmeticsAnna OLEJNIK, Joanna GOŚCIAŃSKA, Izabela NOWAK - Faculty of Chemistry, Adam Mickiewicz University; Poznań Please cited as: CHEMIK 2011, 65, 2, 76-81 The European Commission directives introducing a ban on testing of cosmetics on animals have created great demand for new alternative testing methods. In response, the in vitro studies on cell culture models or skin equivalents have been carried out by global cosmetic concerns for many years. This paper brings a review of the commercially...
Amended guideline of the European Medicines Agency on the investigation of bioequivalence Monika Bogiel - Institute of Biotechnology and Antibiotics, Warsaw Please cited as: CHEMIK 2011, 65, 2, 115-120 An amended EMA Guideline on the investigation of bioequivalence of medicinal products became effective on the 1st of August 2010. It replaced a previous one, effective since 2002: Note for guidance on the investigation of bioavailability and bioequivalence. The coming into force of the revised guideline was an important and widely discussed event for the...Read more
