When was aerosol invented

Over the next century the modern aerosol spray paint can began its rise. In and inventor duo, Helbling and Pertsch, gained a patent for a pressurised aerosol which utilised methyl and ethyl chloride as propellants. However it was not until that the first modern aerosol spray can was introduced to the world. The concept was patented by the Norwegian engineer Erik Rotheim, his patented aerosol can was the first which contained a valve which could hold and dispense products and propellant systems.

This was arguably the forebear of the modern spray can, and in the Norwegian Post Office released a stamp to celebrate the invention of the spray can.

Restrictions on these products are hardly the answer to air pollution. The solution to the smog problem, for example, lies on the freeways and in the power plants…not in the medicine cabinet or the bedroom!

What propellants are used in aerosol containers today? Depending on the end use, either liquefied or compresses gases are used to dispense the product from the aerosol container in the most efficient manner. Neither type is a chlorofluorocarbon. Liquefied propellants, such as isobutene, normal butane or pentane, are natural organic products which do not deplete the ozone layer, taint the soil or pollute the water supply.

They do not contribute to global warming. As used in aerosol cans, their contribution to lower level ozone formation is negligible. Nitrogen, as used in contact lens cleaners and nitrous oxide, as used in whipped toppings, are also used as propellants. If the contribution of aerosols to air pollution is minimal, then why are they suspect? Rather than switching to non-aerosol containers, well-meaning consumers who are concerned about air quality would be far better advised to simply maintain the family car properly!

Once again, myth prevails over reality. For example, pump sprays are generally perceived as being environmentally superior. Actually, the ingredients in the pump container which replace the aerosol propellant, contain many more reactive VOCs than the aerosol package.

The aerosol steel can is fully recyclable; pumps and roll-ons are not. But after all, do we really need aerosols? The aerosol container is a unique package.

It is convenient, effective and efficient. It is hermetically sealed and its contents are always free of bacterial contamination. Web Design by Beanstalk Web Solutions. History of Aerosol Cans. The first use for an aerosol package arose during World War II, but the idea of using low-pressure liquefied gas to atomize droplets of liquid in the air was developed in Aerosols are very fine particles of liquid or solid substances suspended in air.

Sixty-five years ago, U. Department of Agriculture scientists developed the principle of pressurized insect spray.
