Technically speaking, an aerosol is a suspension of fine solid particles or droplets in a gas. The term "aerosol" also refers to a dispenser or package used to turn the contents of a container into an aerosol.
Although 'aerosol' refers to the finished product, it is made up of four parts: the container, the valve, the actuator and the cap. The container can be made of different materials, but is usually made of tinned steel or aluminum. It provides the best conditions for storing the product to be sprayed.
The valve operates as an invisible component, but its role is crucial: it keeps the container gas-tight, clean and hygienic and regulates the flow of product during use.
An actuator or button controls the angle, quantity, shape and fineness of the product spray. The type of content and the use of the aerosol are key factors in the selection of the actuator.
The cap functions as a seal, keeping the product airtight until it is used. It also serves as a decorative component that coordinates the appearance of the product. Some bottle caps act as a propellant for certain products.
An aerosol container is a receiver containing a pressure
A propellant gas, or a mixture of propellant gases, accounts for 5% to 90% of the product. These gases can be compressed or liquefied gases. The liquefied gas acts as a propellant gas and a co-solvent.
One or more solvents
Active ingredients dissolved or suspended in a concentrated liquid solvent
When you press an actuator or button, this activates the valve.
The propellant gas exerts pressure on the active product and solvent solution, forcing the liquid to rise through the impregnation tube, which opens and passes through the valve, allowing the product to be discharged with the propellant in the form of droplets, foam, paste or powder.
