Description and Uses
Ethylenediamine is used in numerous industrial proces ses as a solvent for casein or albumin, as a stabilizer in rubber latex and as a textile lubricant. It can be found in epoxy-resin hardeners, cooling oils, fungicides, and waxes. Contact dermatitis from ethylenediamine is almost exclusively due to topical medicaments. Occupational contact dermatitis in epoxy-resin systems is rather infrequent. Ethylenediamine can cross react with triethylenetetramine and diethylenetriamine. Ethylenediamine was responsible for sensitization in pharmacists handling aminophylline suppositories, in nurses preparing and administering injectable theophylline, and in a laboratory technician in the manufacture of aminophylline tab lets.
Intermediate in the manufacture of EDTA; catalytic agent in epoxy resins; dyes, solvent stabilizer; neutralizer in rubber products
