Dipropylene Glycol Butyl Ether is a cleaning agent that can also be found in cosmetics such as facial soaps because of its ability to dissolve dirt and other substances and to retain moisture. It’s particularly good at removing soap scum, mold and mildew stains. Like its sister ingredient Dipropylene Glycol Propyl Ether, it works by loosening the scum or stain from a surface. It is readily biodegradable, and is unlikely to bioaccumulate in the environmental food chains. Additionally, Dipropylene Glycol Butyl Ether is less toxic to aquatic organisms than many alternatives.
