What Is a Carcinogenic Agent in Air Fresheners?

Ingredients in air fresheners, listed or unlisted, have been discovered as known carcinogens (a substance that can lead to cancer).

Types

• Ingredients in air fresheners known as formaldehyde and naphthalene have been identified by the American Cancer Society as substances that may cause cancer. These two substances can be found in both air fresheners and plug-ins.

Effects

• Carcinogens may not always lead to cancer. According to the American Cancer Society, "they may cause cells to divide at a faster than normal rate, which could increase the chances that DNA changes will occur."

Function

• Air fresheners are used to perfume the air in a room in order to mask offensive odors.

Misconceptions

• Air fresheners only mask odors in the air by coating "the nasal passages with an oil film (such as methoxychlor--a pesticide that accumulates in fat cells) or by releasing a nerve deadening agent," according to Healthinmotion.wordpress.com.

Warning

• Formaldehyde can be toxic if it is inhaled and poisonous if swallowed. It can also lead to skin and eye irritation. Naphthalene, a known carcinogen, "can be irritating to the skin, alter kidney function, cause cataracts, and is toxic (cardiovascular and developmental), especially to children," according to Julie Felming, the MCS-Global Georgia State coordinator.
