Application

Ethylene glycol butyl ether is used as a co-solvent:,In the preparation of conductive inks.

General description

Ethylene glycol butyl ether is a member of the glycol ether family. It is commonly used as a solvent for pharmaceuticals, agricultural chemicals hydraulic fluids, resins, and varnishes. Ethylene glycol butyl ether or 2-Butoxyethanol (BEG) has an amphiphilic character, it can be utilized to stabilize emulsions, particularly in oil spill dispersants.

We determined percutaneous absorption kinetics of 2-butoxyethanol (BE) in volunteers using microdialysis. Four male volunteers were dermally exposed twice to 90% and 50% aqueous solutions (v/v) of BE for 4.5h. To determine percutaneous absorption kinetics the concentration of BE was

2-butoxyethanol (2BE) is a solvent commonly incorporated into household and industrial cleaning products. Its ingestion causes rapid central nervous system depression, hypotension, and metabolic acidosis attributable to metabolism of the parent compound to butoxyacetic acid (BAA) by alcohol dehydrogenase.

2-Butoxyethanol increases hemangiosarcomas selectively in male mouse liver after chronic inhalation through mechanisms that have not fully been elucidated. Hemolysis, a primary toxic effect associated with 2-butoxyethanol exposure in rodents, increased hemosiderin (iron) deposition in Kupffer cells in the liver.
