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.

Absorption of 2-butoxyethanol (BE) from neat and aqueous solutions of BE was measured through rat skin in vitro and in vivo and through silicone membranes. Like previous studies in human and guinea pig skin, BE flux increased proportional to BE

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
