History of Aerosols
In 1927, Erik Rotheim, a Norwegian engineer filed the patent for what would become a phenomenal success story: the aerosol dispenser. The successful development of mass produced aerosols occurred in the USA during the late 40s. It was an insecticide called the ‘bug bomb’ developed by Goodhue & Sullivan.
American soldiers used it to fight insect borne diseases in the Pacific; 50 million units were produced during World War II. The aerosol package expanded soon after the war. In 1947, 4.3 million units were manufactured for civilian applications. Production increased steadily and soon crossed the Atlantic Ocean to reach Europe.
Insecticides and hairsprays were the first products to hit the European market in the early 50s. Air fresheners, deodorants and shaving foams soon followed and approximately 70 million aerosols were produced in Europe during this period.
In the early 60s the golden age of the aerosol industry emerged. A wider range of aerosol products came onto the market; they were originally made of extruded aluminium but were soon made of tinplate as well.
Production stunned again, reaching a total 2.2 billion units; an increase of 80 % over the decade!
In the late 70s, a tidal wave of environmental concern captured the world’s attention after the publication of the 'Molina/Rowland' report on the ozone layer. The aerosol came to represent for the role that CFCs were thought to play in the thinning of the upper ozone layer, despite its relatively minor contribution to the phenomenon.
In the 80s, the aerosol industry voluntarily moved away from CFCs to alternative propellants and A 'CFC free' labelling was introduced in Europe.
European consumer aerosols (except for a small number of medical products such as asthma inhalers) have not contained CFCs since 1989.
Production during this decade rose by 35 % and reached 3 billion units.
The protection of the environment has become a European key issue since the early 90s.
Research & Development focused on propellants, packaging and ingredients to make the aerosol a high performance product.
The bicompartimented aerosol offered a new generation of aerosol technology and started to expand rapidly.
European aerosol production steadily continued and reached 4.4 billion, a 48 % growth over the decade, positioning Europe as the production leader worldwide.
Aerosol packages were presented in new shapes and were more attractive and ergonomic. Europe still led in aerosol production worldwide with 5 billion units produced. Nearly 12 billion were produced worldwide in 2008.
Compressed gas propellants will be used more widely and the aerosol industry will focus on the production of cheaper aerosol containers. Efforts will be maximised to improve new systems like self-compressing bags while plastic aerosols will further develop in the market.
