Basics of Aerosol
Aerosol Product Definition
The CSMA defines an aerosol product as follows:
"A self-pressurized packaging form, consisting of a metal, glass or plastic container with a permanently attached continuous or metering valve, and designed to dispense products as sprays, streams, gels, foams, lotions or gases. Sizes range from about 0.1 fluid ounce (2.8 mL) to 33.8 fluid ounces (1 liter). (Note: The scientific term "aerosol" refers to small particles of a liquid or solid suspended in gas.)"
Overview of an aerosol container
The first aerosol package was developed during World War II. The first products were insecticides used to protect US servicemen from disease carrying insects. After the war, aerosols were adapted for a wide range of consumer and commercial products.
Aerosols and the Environment
In 1974, scientists proposed the theory that chlorofluorocarbons (CFCs) damage the ozone layer. Prior to that time CFCs were used as propellants in aerosol products. Aerosol manufacturers began to discontinue the use of CFC before the U.S. banned them in 1978. In 1987, 24 countries signed The Montreal Protocol On Substances That Deplete The Ozone Layer, each agreeing to gradually phase out the use of Ozone Depleting Compounds, including CFCs. The protocol eventually fully phased out CFCs in 1996. In 2020, complete global phase out of the ODC Hydrochlorofluorocarbons (HCFCs) is expected to be completed under the guidelines of the Montreal Protocol Agreement.
We are proud to say that Sara Chem has not been using CFC's since 1995 when this mandate came for India.
Aerosol Cans are Recyclable
Approximately 90% of aerosol cans are made of tinplated steel, about 10% are made of aluminum. Both types of cans are recyclable. A new steel container is made from more than 25 percent recycled steel.
