The use of preservatives must be optimized in order to ensure the efficacy of an antimicrobial system as well as the product safety. Despite the wide variety of preservatives, the synergistic or antagonistic effects of their combinations are not well established and it is still an issue in the development of pharmaceutical and cosmetic products. The purpose of this paper was to establish a spac...

The vasoactivity of lignocaine has an important influence on its clinical efficacy and systemic vascular absorption. The aim of this study was to evaluate its vasoactive properties when administered by the non-invasive technique of iontophoresis. We used laser Doppler imaging to measure the forearm skin blood flow responses of seven healthy young males to iontophoretic delivery of two preparati...

Parabens are a group of chemicals used as preservatives in many industrial products such foods, cosmetics, and pharmaceuticals. Recent studies have revealed that these endocrine disrupting properties. Drosophila melanogaster is one the suitable model organisms to test toxic effect various vivo. In this study, effects methylparaben (MP) (50 mM, 100 200 mM), most commonly parabens, on development...

The aim of this study was to compare the efficiency pharmaceuticals and personal care products’ (PPCP) removal in waterworks at Káraný (Czech Republic) Dresden-Hosterwitz (Germany). Both use similar technology drinking water production (combination bank filtration artificial recharge) have river quality (Jizera Elbe river). A comparison 2-year monitoring results shows high removing PPCP contain...

Abstract Carbon-based adsorbents were produced from onion skin waste for the adsorption of methylparaben contaminated water. The biomass-derived carbon was characterized using various established analytical techniques. microscopic examinations revealed micro- and mesoporous structures with a partially disordered network graphenic carbon-like multilayer structure, confirmed by XPS Raman spectra....

This paper describes for the first time surface modification of glassy carbon (GC) electrodes with bamboo-based renewable (RC) and antimony nanoparticles (SbNPs) determination methylparaben (MePa) in personal care products (PCPs). The synthesized RC-SbNP material was successfully characterized by scanning electron microcopy, energy-dispersive X-ray spectroscopy cyclic voltammetry. proposed sens...
