David W Roberts et al.
Contact dermatitis, 66(3), 123-127 (2012-02-11)
Skin-sensitizing chemicals that cause allergic contact dermatitis do so by reacting with self-proteins such that the modified structure becomes antigenic. The reaction chemistry involved is well characterized, but there are exceptions, such as the occasional allergen sodium metabisulfite. To identify

A 2,4-dinitrophenylhydrazine (DNPH) precolumn derivatization high-performance liquid chromatography-ultraviolet detection (HPLC-UV) method was developed to quantify levels of formaldehyde and acetaldehyde in polyethylene glycol (PEG) solutions. Formic acid and acetic acid were quantified by HPLC-UV. Samples of neat and aqueous PEG
