Emulsions are a class of disperse systems consisting of two immiscible liquids [1–3]. The liquid droplets (the disperse phase) are dispersed in a liquid medium (the continuous phase). Several classes may be distinguished: oil-in-water (O/W), water-in-oil (W/O), and oil-in-oil (O/O). The latter class may be exemplified by an emulsion consisting of a polar oil (e.g., propylene glycol) dispersed i...

Abstract Disperse Orange 1, colour index 11080, is an azo dye. Collectively, dyes are a common cause of textile-related allergic contact dermatitis (ACD). A 2006 European Union (EU) directive restricts the sale any articles or dyed items that have direct and prolonged with skin oral cavity contain more than 30-ppm dyes. These include wide range such clothing, bedding, furniture, toys yarn. Desp...
Four novel azo disperse dyes based on 1-4-bromobenzyl-4-phenylpiperazine were synthesized in two steps, using alkylation and azo coupling reactions. Chemical structure of the dyes was characterized and confirmed by the Ultraviolet Visible UV-Visible, Fourrier Transform Infrared FT-IR, Proton Nuclear Magnetic Resonance 1H NMR and Carbon Nuclear Magnetic Resonance 13C NMR analyses. The solvatochr...
