This extract is produced by environmentally friendly practices using waste onion peels as raw material and then extracted with water and alcoholic solvent for the extraction of querctin, the flavonides responsible for the yellow color. The extract produces bright yellow to greenish hue on different natural and also synthetic fibers at different pH and dye concentration, and also shows diverse antimicrobial activity against bacteria and C.Albicans, and the results are relatively sensitive and resistant to S.Aureus.
