Organic Colouring Agents in the Pharmaceutical Industry

September 2017

Food dyes are largely used in the process of manufacturing pharmaceutical products. The aim of such a procedure is not only to increase the attractiveness of products, but also to help patients distinguish between pharmaceuticals. Various dyes, especially organic colouring agents, may in some cases have a negative impact on the human body. They are incorporated into pharmaceutical products … [Show full abstract] including tablets, hard gelatine capsules or soft gelatine capsules, lozenges, syrups, etc. This article provides an overview of the most widely used colouring agents in pharmaceuticals, their characteristics and the EU legislation which regulates their use.

The Characterization of Vegetable Tannins and Colouring Agents in Ancient Egyptian Leather from the…

January 2016 · Archaeometry

This work characterizes both tanning and colouring materials found in ancient Egyptian leather objects from the Metropolitan Museum of Art. The analytical investigations focused on assessing the development of the technology of ancient tanners using high-performance liquid chromatography (HPLC), surface-enhanced Raman spectroscopy (SERS), X-ray fluorescence (XRF), Fourier transform infrared … [Show full abstract] spectroscopy (FT-IR), X-ray radiography and a scanning electron microscope connected to an energy-dispersive X-ray detector (SEM-EDX). Reference leather samples and archaeological leather objects were investigated to identify the animal skin species and the early use of hydrolyzable vegetable tannins for leather tanning. Different methods were used to colour th leather, including madder dying and staining with hematite, or painting with Egyptian blue and Egyptian green.

Chemical composition and colouring agents of Roman mosaic and millefiori glass, studied by electron…

January 2009 · Archaeological and Anthropological Sciences

About 100 fragments of Roman mosaic and millefiori glass were stylistically attributed to a Hellenistic type, a Ptolemaic
and Romano-Egyptian period type and an early imperial period type. Twelve representative fragments were studied by electron
microprobe analysis and Raman microspectroscopy. Eleven of them display a Na-pronounced recipe with low K, Mg and P contents,
typical for the Roman … [Show full abstract] period. Minor differences in composition are unsystematic, not reflecting the stylistic classification.
Ionic colouring agents are Mn3+ for violet, Cu2+ for light blue, Co2+ for deep blue and Fe3+ for brown translucent colours. Calcium antimonates, lead antimonate and cuprite are the colourants responsible for white,
yellow and red colours, respectively, and additionally serve as opacifiers. Mixing of ionic colouring agents and opacifying
colourants led to a more differentiated palette of colours. Pb was used as yellow colouring agent, as a flux material and
as a stabiliser for the colourant crystals. The remaining fragment consisting of a K-pronounced but still Na-bearing glass
matrix was most likely produced during the Middle Ages or later.

Composition and colouring agents of historical Islamic glazes measured with EPMA and mu-XRD2 (vol 27…

September 2015 · European Journal of Mineralogy

Glazes from tiles of representative historic Islamic buildings and tableware ceramic from Central Asia, the Middle East, Asia Minor and North Africa were analysed by electron probe microanalysis (EPMA) and two-dimensional micro-X-ray powder diffraction (m-XRD 2). From major element compositions, three main glaze types were identified: alkali, alkali–lead and lead glazes. Quartz frit and clay … [Show full abstract] ceramics form the substrates of the glazes. A slight influence of the ceramic on the glaze compositions can be found for SiO 2 , Al 2 O 3 and K 2 O, but only for quartz frit substrates. PbO and/or alkali oxides were used as fluxes. Na 2 O is the dominant oxide in the alkali flux. MgO and P 2 O 5 are the decisive components for the discrimination between mineral soda and plant ash as a source of the alkali flux. The use of plant ash beside the established mineral soda as flux for the glazes was introduced during the 13 th century in Iran, latest during the 13 th /14 th century in Afghanistan, and during the 14 th /15 th century in Uzbekistan. Hence, a change of the flux happened later for the glazes than for local glass of the same regions. Lead-glaze compositions occur in almost all considered epochs and locations. Colouring ions are Co 2þ (blue), Cu 2þ (green in a Pb-rich matrix), Fe 3þ and Mn 4þ (brown/black) and Mn 3þ (violet). Pigments, such as SnO 2 , SiO 2 and PbSiO 4 , are whitening agents; Pb 2 Sn 2 O 6 was used for yellow colours. Iron-containing clinopyroxenes and Cu-Cr-Mn-oxides are found in black glazes.
