The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...

Organic aromatic compounds used for dyeing and coloring in the textile industry are persistent hazardous pollutants that must be treated before they discharged into rivers surface waters. Therefore, we investigated potential of white rot fungus Phanerochaete velutina to decolorize commonly reactive dyes. The decolorized average 55% Reactive Orange 16 (RO-16) after 14 days at a maximum rate 0.09...

Hair dyes are more and more used and the role of the exposure to these products in the development of skin reactions in the exposed region is suspected. The aim of this study is to assess the effects of hair dyes on facial skin and scalp sensitivity by performing a Computer Assisted Web Interview on 1257 women older than 15 years old. Differences were observed in the scores evaluating facial sk...

Microbial iron reduction is an important biogeochemical process and involved in various engineered processes, including the traditional clay dyeing processes. Bioaugmentation with iron reducing bacteria (IRB) is generally considered as an effective method to enhance the activity of iron reduction. However, limited information is available about the role of IRB on bioaugmentation. To reveal the ...

A novel chitosan-based biopolymer dye possessing antibacterial properties was synthesized by reaction of O-carboxymethyl chitosan and Acid Red GR. The synthesized materials were characterized by Fourier transform infrared spectroscopy (FTIR), degree of substitution (DS), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), X-ray diffraction (XRD), water solubility test, anti...

Laccase efficiently catalyses polymerization of phenolic compounds. However, knowledge on applications of polymers synthesized in this manner remains scarce. Here, the potential of laccase-catalysed polymerization of natural phenols to form products useful in hair dyeing was investigated. All 15 tested phenols yielded coloured products after laccase treatment and colour diversity was attained b...
