Question

What is the chemical used in mosquito repellent incenses stick..

Answer 1

Aerosols are the most common form for mosquito repellents. They are made up of a few different types of ingredients, including a solvent, a propellant, and miscellaneous ingredients. The solvent is usually an organic alcohol such as ethanol or propanol, whose primary responsibility is to dilute the active ingredient to an appropriate concentration. It also aids in keeping all of the raw materials mixed, ensuring that the product will remain effective even after long-term storage. The propellant is a volatile compound which creates the pressure that causes the rest of the product to be forced out of the container. Common propellants include liquified hydrocarbongases like propane, butane, or isobutane, hydrofluorocarbons, and dimethyl ether. Other ingredients such as fragrances and emollients are added to aerosol mosquito repellents to make them more cosmetically appealing. Still other compounds are added to prevent corrosion and other stability problems.
