History
Fragrance compounds have been used since antiquity to freshen air and mask odors, For example, the ancient Egyptians were known to use musks and other natural materials to scent their tombs. Over the last 2,000 years a variety of compounds, including numerous spices and floral extracts, have been used for their ability to impart a pleasant aroma. However, it was not until 1948 that the first modern air freshener was introduced. This product, using technology developed by the military to dispense insecticides, was a pressurized spray containing about 1% perfume, 24% alcohol or other solvents, and 75% chlorofluorocarbon (CFC) propellant. This was able to deliver a fine mist of fragrance that remained suspended in the air for a long period of time.

Today as the popularity of these scented air fresheners are on the rise, allergists are hearing more complaints about reactions to these toxic scented products."
