Aerosol products contain a formula consisting of the bulk combined with a propellant. By shaking the bottle before use, these two elements mix and ensure the correct supply of the product.

Generally, in the cans on the market, the propellant used is LPG which, to be effective, is used in a higher percentage if compared to the product. This means that the ml indicated on the packaging refer to the total content, that is the sum of the percentage of propellant mixed with the product.

Does it exist another way which allows you to increase the product contained in each can and meantime reduce the environmental impact? The answer is… yes. In fact, nitrogen has been used for some time as a propellant combined with the product. This allows to considerably reduce the percentage of propellant and therefore to increase the one of the product.

Thanks to the properties of nitrogen, while keeping the same percentage of active ingredients, it is possible to use a smaller size can than the one used for LPG. This allows to reduce material consumption and make transport more efficient for a lower environmental impact, with less CO2 emissions (carbon footprint).

Due to the characteristics of this compressed gas, the use of aluminum cans is the best choice thanks to their technical properties which perfectly match nitrogen features. Obviously, aluminum cans also have remarkable characteristics of sustainability: they can be easily recycled and are a perfect example of a circular economy considering that aluminum is a permanent material and consequently infinitely recyclable.
