Acryloyl esters of emodin for waterless dyeing and toxicological studies

Gabriel Rampazzo Magalhães,

Abstract: Traditional textile dyeing processes usually require large quantities of water and energy and generate wastewater that can be harmful to the environment. Dyeing in supercritical carbon dioxide (sc‐CO2) media is promising in textile coloration due especially to it providing a waterless process and eliminating the need for an energy intensive drying step. The natural anthraquinone emodin showed promising results for dyeing different fibres through sc‐CO2 process. However, emodin is mutagenic. The aim of this stu… Show more

“…Also, their cytotoxicity was non-existent or low, even though they increased oxidative stress in the two studied human cell lines. Instead, emodin, the most abundant anthraquinone in C. sanguineus , is known to be mutagenic after metabolic activation in the Ames test [ 20 , 21 ] and suspected to be a reproductive toxicant [ 22 ], among other effects [ 18 ]. In a micronucleus assay conducted with a sea crustacean, Parhyale hawaiensis , emodin, along with its chemically modified derivatives, increased the formation of micronuclei, which is a sign of genotoxicity [ 21 ].…”
