For the usage in aerosols, the odorant needs to be removed from LPG, as it cannot be added in the product with the odorant present. Hence, de-odorizing systems or de-odorizing columns are used to remove the odorant such as mercaptan from the LPG.
In aerosols, LPG is stored in a pressurised container along with the product being dispensed. When the valve is opened, the LPG vaporises and expands rapidly, propelling the product out of the container in a fine mist or spray. LPG is used as a propellant in a wide range of aerosol products, including personal care products, household cleaners, insecticides, and automotive products.
