“…confectionery, boiled fish and soft drinks, but they are not allowed as a food additive in either the US or the EU. Only the natural red colorant 'cochineal extract' (additive E-120(ii)) which is an extract of the dried bodies of the female cochineal insect, with around 20% carminic acid content, is allowed and widely used as a colouring agent in food processes in the EU (at dosage levels from 50 to 500 mg/kg) and in the US (only up to 5 mg/kg) 7,15,22,38 . Cochineal is commonly cultivated from the wild prickly pear cactus that grows thickly on the mountainsides in central Peru.…”

Natural pigments and colorants are widely used in the world in many industries such as textile dying, food processing or cosmetic manufacturing. Among the natural products of interest are various compounds belonging to carotenoids, anthocyanins, chlorophylls, melanins, betalains… The review emphasizes pigments with anthraquinoid skeleton and gives an overview on hydroxyanthraquinoids described in Nature, the first one ever published. Trends in consumption, production and regulation of natural food grade colorants are given, in the current global market. The second part focuses on the description of the chemical structures of the main anthraquinoid colouring compounds, their properties and their biosynthetic pathways. Main natural sources of such pigments are summarized, followed by discussion about toxicity and carcinogenicity observed in some cases. As a conclusion, current industrial applications of natural hydroxyanthraquinoids are described with two examples, carminic acid from an insect and Arpink red™ from a filamentous fungus.

In this research, the effect of zirconium salt as a mordant on flammabilityof dyeingwool fabric with madder was studied.Wool fabrics were treated with different concentrations of zirconium salt in water solution including 1, 3, 6 and 9% o.w.f. and the dyeing process was carried out on the fabrics in the states before, simultaneously and after-mordanting with madder. Formic acid and oxalic acid were used to generate acidic pH.The chemical characteristics and the changes induced by zirconium were investigated by Fourier-transform infrared spectra (FTIR). Flammability of samples was investigated by horizontal flammability test (HFT). The surfaces of untreated and treated fabrics were evaluated by scanning electron microscopy to observe the morphological changes. The EDX results showed presence of zirconium salt on the surface of wool.The results show that zirconium treated fabrics have a higher weight and lower bending rigidity compared to untreated ones. Furthermore,the zirconium mordant made the wool fabric hydrophobic.

Since the last decade, the application of natural dyes on textile materials is gaining popularity all over the world, possibly because of increasing awareness of environment, ecology, and pollution control. In this research, extraction of dyes from madder at different conditions has been studied. The extracted dyes from madder were examined by TLC and HPLC. The adsorption properties of the dyes extracted from madder on natural polyamide fibers (wool) were also determined. The rate of dyeing at different temperatures, as well as the values of standard affinity, entropy, and enthalpy was calculated. The results indicated that increase of temperature leads to decrease the values of partition ratio and affinity. The adsorption isotherm was tested by fitting the adsorption data with Langmuir, Freundlich, BET, and Temkin isotherms.
