These products are not aerosols so they contain 100% de-icer and no wasteful propellant.
F-JAS De-icer is designed to work fast. A premium ingredient, usually found in Rain Repellent, gets to work chemically interacting with the glass, in the process disturbing the adhesion of the ice to the glass. The blend of Iso-Propyl Alcohol and Surfactant combine to lower the freezing point of water and chemically disrupt the hydrogen bonds that make up the ice layer.
The video below shows how quickly F-JAS De-Icer melts a typical layer of ice and frost on a windscreen.
