Common Hazardous Ingredients in Cleaning Products

Aerosol products - Aerosol propellants may contain propane, formaldehyde (a carcinogen, neurotoxin and central nervous system depressant), methylene chloride (a carcinogen, neurotoxin and reproductive toxin), and nitrous oxide. Products applied with aeresol sprays are broken into minute particles, which can be more deeply inhaled than larger particles, which may increase their toxic effect.

Air fresheners - Far from freshening air, chemical-based air fresheners and deodorizers add dangerous chemicals to the air we breathe. Air fresheners work by using a nerve-deadening chemical that interferes with our sense of smell, by coating nasal passage with an oily film, by masking an offending odour with a different odour, or by deactivating the odour. Air fresheners are made from many chemicals including naphthalene, a suspected carcinogen, xylene, a neurotoxin and possible reproductive toxin, butane gas, a neurotoxin, cresol, ethanol, phenol, and strong fragrances. Some solid deodorizers include the pesticide paradichlorobenzene, a carcinogen which can also cause liver and kidney damage. Aerosol air fresheners release chemicals as tiny particles which can be inhaled deeply into lungs and transferred into the blood stream. Plug in air fresheners break chemicals into even smaller particles.

Ammonia - Undiluted, ammonia is a severe eye and respiratory irritant that can cause severe burning pain, and corrosive damage including chemical burns, cataracts and corneal damage. It can also cause kidney and liver damage. Repeated or prolonged exposure to vapours can result in bronchitis and pneumonia. Found in a wide range of cleaning products. Ammonia will react with bleach to form poisonous chlorine gas that can cause burning and watering of eyes, as well as burning of the nose and mouth.

Diethanolamine (DEA) - This chemical is a skin and respiratory toxicant and a severe eye irritant.

Ethoxylated nonyl phenol - Nonyl phenols are hormone disruptors and some contain traces of ethylene oxide, a known human carcinogen. They are eye and skin irritants. Used in laundry detergents and other cleaning products.

Formaldehyde - In lab tests, formaldehyde has caused cancer and damaged DNA. Formaldehyde is also a sensitizer, with the potential to cause asthma. Several laboratory studies have shown it to be a central nervous system depressant. Exposure to formaldehyde may cause joint pain, depression, headaches, chest pains, ear infections, chronic fatigue, dizziness and loss of sleep. While formaldehyde naturally occurs in the human body in minute amounts, it is estimated that 20 per cent of people exposed to it will experience an allergic reaction. Used in a wide range of products, including some furniture polishes.

Fragrance - can indicate the presence of up to 4,000 separate ingredients, most of which are synthetic. Many compounds are human toxins and suspected or proven carcinogens. In 1989, the US National Institute of Occupational Safety and Health evaluated 2,983 fragrance chemicals for health effects. They identified 884 of them as toxic substances. Synthetic fragrances are known to trigger asthma attacks. The US Environmental Protection Agency found that 100% of perfumes contain toluene, which can cause liver, kidney and brain damage as well as damage to a developing fetus. Symptoms reported to the FDA from fragrance exposure have included headaches, dizziness, rashes, skin discoloration, violent coughing and vomiting, and allergic skin irritation. Clinical observations by medical doctors have shown that exposure to fragrances can affect the central nervous system, causing depression, hyperactivity, irritability, inability to cope, and other behavioral changes. Fragrance is a common skin irritant.

Monoethanolamine - This chemical may cause liver, kidney and reproductive damage, as well as depression of the central nervous system. Inhalation of high concentrations - when cleaning an oven for example - can cause dizziness or even coma. The chemical can also be absorbed through the skin. It is a moderate skin irritant, and a severe eye irritant. Found in many cleaning products, including oven cleaners, tub and tile cleaners, laundry pre-soaks, floor strippers and carpet cleaners.

Morpholine - This corrosive ingredient can severely irritate and burn skin and eyes, and can even cause blindness if splashed in eyes. It can cause liver and kidney damage, and long-term exposure can result in bronchitis. It reacts with nitrites (added as a preservative in some products, or present as a contaminant) to form carcinogenic nitrosomines. Morpholine is a moderate to severe eye, skin and mucous membrane irritant. Used as a solvent in a number of cleaning products, including some furniture polishes and abrasive cleansers.

Parabens - Parabens are hormone disruptors. Widely used in cleaning products as preservatives, paraben is usually preceded by the prefixes methyl-, ethyl-, butyl-, or propyl. Parabens may cause contact dermatitis in some individuals.

Phosphoric acid - Extremely corrosive, it can severely irritate and burn the skin and eyes. Breathing vapours can make the lungs ache, and it may be toxic to the central nervous system. Found in some liquid dishwasher detergents, metal polishes, some disinfectants, and bathroom cleaners, especially those that remove lime and mildew.

Sodium hypochlorite (bleach) - A corrosive chemical, sodium hypochlorite is an eye, skin and respiratory irritant, as well as a sensitizer. It is especially hazardous to people with heart conditions or asthma, and can be fatal if swallowed. It may be a neurotoxin and toxic to the liver. Found in a wide range of household cleaners.

Toluene - Exposure may cause liver, kidney and brain damage. It is also a reproductive toxin which can damage to a developing fetus.

Turpentine - Can cause allergic sensitization, and kidney, bladder and central nervous system damage. It is an eye irritant. Found in specialty solvent cleaners, furniture polish.
