Propel water is water stored in an aerosal container and mixed with a propellant such as butane or propane. This type of water is often used for cleaning or other purposes, and is generally considered safe for use. However, it is important to ensure the water is consumed in small quantities, and that it is not inhaled or sprayed directly onto the skin or eyes. If ingested, propel water can cause health problems such as breathing difficulties and nausea. Therefore, it is recommended that propel water be used with caution and in accordance with the manufacturer's instructions.
