Consumer Warning: Most air fresheners contain formaldehyde, sodium nitrate, ethanol, phthalates, benzene, or diethylhexyl. Inhalation of formaldehyde can negatively affect the central nervous system causing nausea, drowsiness, fatigue, and headaches. Sodium nitrate found in most plug-in air fresheners is a flammable and toxic substance that can cause hypoxia, hand tremors, and problems with the cardiovascular system.
Ethanol causes problems with a reduced oxidation reaction, which may lead to vitamin B1 and vitamin C deficiency. Ethanol can also cause dizziness, nausea, and decreased visual acuity. Phthalates can accumulate in the kidneys and liver. This toxic accumulation negatively affects the endocrine system. Too much exposure to benzene can cause benzene intoxication includes rapid heartbeat, drowsiness, and dizziness.
Diethylhexyl triggers the accumulation of harmful lipids in the body.
