Propellants help to develop proper pressure within the container and expel the products in the forms of vapor in the formulation of aerosols. A propellant is a chemical with a vapor pressure greater than atmospheric pressure at 40°C (105°F).

How do propellants work?

A liquified gas is usually used as a propellant. ... As it is released, the gas evaporates from the liquid in the container causing constant performance and pressure within the aerosol. When the liquid mixture is released from the aerosol, the liquid propellant becomes a gas and helps break up the product into a fine mist.

What is propellant give example?

Most liquid chemical rockets use two separate propellants: a fuel and an oxidizer. Typical fuels include kerosene, alcohol, hydrazine and its derivatives, and liquid hydrogen. Many others have been tested and used. Oxidizers include nitric acid, nitrogen tetroxide, liquid oxygen, and liquid fluorine.
