Di(ethylene glycol) ethyl ether (2-(2-Ethoxyethoxy)ethanol, CARBITOL™, Diethylene glycol monoethyl ether[5], Ethyldiglycol, diEGEE[5]) is an ethylene oxide-based glycol ether solvent. Di(ethylene glycol) ethyl ether is a glycol ether. Reproductive toxicity of di(ethylene glycol) ethyl ether (diethylene glycol monoethyl ether, diEGEE) has been evaluated. The effect of diethylene glycol monoethyl ether (DGME, Transcutol) on the permeation of a broad-spectrum antiparasitic agent, ivermectin, through bovine skin has been evaluated by in vitro permeation experiments. Di(ethylene glycol) ethyl ether is a cellosolve and excess molar enthalpy of binary (cellosolve+1-butanol) mixtures have been determined.
