The average household contains about 62 toxic chemicals, say environmental experts. We are exposed to them routinely — from the phthalates in synthetic fragrances to the noxious fumes in oven cleaners. Ingredients in common household products have been linked to asthma, cancer, reproductive disorders, hormone disruption and neurotoxicity. Needless to say, our animal companions gain unnecessary exposure to the aforementioned harmful ingredients.
Manufacturers argue that in small amounts these toxic ingredients are not likely to be a problem, but when we ourselves and our animal companions are exposed to them routinely, and in combinations that have not been studied, it is impossible to accurately gauge the risks.
While a few products cause immediate reactions from acute exposure (headaches from fumes, skin burns from accidental contact), different problems arise with repeated contact. Chronic exposure adds to the body’s “toxic burden” — the number of chemicals stored in its tissues at a given time. As such, more often than not, we have hard-to-identify allergies appearing on our animal companions as their threshold against the toxins have been breached.
No one can avoid exposure to toxic chemicals altogether, but it is possible to reduce it significantly. We would be exploring how experts weigh in on the worst toxic offenders commonly found in household cleaning products, and offer ways to swap them for healthier, safer options.
1. Phthalates
Found in: Many fragranced household products, such as air fresheners, dish soap, even toilet paper. Because of proprietary laws, companies do not have to disclose what is in their scents, so you would not find phthalates on a label. If you see the word “fragrance” on a label, there is a good chance phthalates are present.
Health Risks: Phthalates are known endocrine disruptors. Men with higher phthalate compounds in their blood had correspondingly reduced sperm counts, according to a 2003 study conducted by researchers from the Centres for Disease Control and Prevention and the Harvard School of Public Health.
Although exposure to phthalates mainly occurs through inhalation, it can also happen through skin contact with scented soaps, which is a significant problem, warns Alicia Stanton, MD, coauthor of Hormone Harmony (Healthy Life Library, 2009). Unlike the digestive system, the skin has no safeguards against toxins. Absorbed chemicals go straight to organs.
Healthier Choice: When possible choose fragrance-free or all-natural organic products. Beth Greer, author of Super Natural Home, recommends bypassing aerosol or plug-in air fresheners and instead using essential oils or simply opening windows to freshen the air. Besides causing more serious effects like endocrine disruption, “Aerosol sprays and air fresheners can be migraine and asthma triggers,” she says. Also consider adding more plants to your home: They are natural air detoxifiers.
Our animal companions possess a fragile respiratory system, compared with ours so opting for natural alternatives like essential oils burning would be a better choice. Choosing the right essential oil is of great importance too. Consult a naturopathic practitioner or aromatherapist for advice if need be.
2. Perchloroethylene or “PERC”
Found in: Dry-cleaning solutions, spot removers, and carpet and upholstery cleaners.
Health Risks: PERC is a neurotoxin, according to the chief scientist of environmental protection for the New York Attorney General’s office. And the EPA classifies PERC as a “possible carcinogen” as well. People who live in residential buildings where dry cleaners are located have reported dizziness, loss of coordination and other symptoms. While the EPA has ordered a phase-out of PERC machines in residential buildings by 2020, California is going even further and plans to eliminate all use of PERC by 2023 because of its suspected health risks. The route of exposure is most often inhalation: that tell-tale smell on clothes when they return from the dry cleaner, or the fumes that linger after cleaning carpets.
Healthier Choice: Curtains, drapes and clothes that are labeled “dry clean only” can be taken instead to a “wet cleaner,” which uses water-based technology rather than chemical solvents. The EPA recently recognised liquid carbon dioxide (CO2) as an environmentally preferable alternative to more toxic dry-cleaning solvents. Ask your dry cleaner which method they use. For a safer spot remover, look for a nontoxic brand at a natural store, or rub undiluted castile soap directly on stains before washing. Be very careful when exposing your animal companions to your outerwear that requires dry-cleaning if you are unsure if the solvents used are chemical-based. More often than not, they are.
3. Triclosan
Found in: Most liquid dishwashing detergents and hand soaps labeled “antibacterial.”
Health Risks: Triclosan is an aggressive antibacterial agent that can promote the growth of drug-resistant bacteria. Explains Sutton: “The American Medical Association has found no evidence that these antimicrobials make us healthier or safer, and they are particularly concerned because they do not want us overusing antibacterial chemicals — that is how microbes develop resistance, and not just to these [household antibacterials], but also to real antibiotics that we need.”
Other studies have now found dangerous concentrations of triclosan in rivers and streams, where it is toxic to algae. The EPA is currently investigating whether triclosan may also disrupt endocrine (hormonal) function. It is a probable carcinogen. At press time, the agency was reviewing the safety of triclosan in consumer products.
Healthier Choice: Use simple detergents and soaps with short ingredient lists, and avoid antibacterial products with triclosan for home use. If you are hooked on hand sanitizer, choose one that is alcohol-based and without triclosan. Avoid using products with antibacterial function on animal companions as it weakens the infrastructure of their skin, thereby leading to unknown reasons for skin sensitivities.
4. Quarternary Ammonium Compounds, or “QUATS”
Found in: Fabric softener liquids and sheets, most household cleaners labeled “antibacterial.”
Health Risks: QUATS are another type of antimicrobial, and thus pose the same problem as triclosan by helping breed antibiotic-resistant bacteria. They are also a skin irritant; one 10-year study of contact dermatitis found quats to be one of the leading causes. According to Rebecca Sutton, PhD, a senior scientist at the Environmental Working Group (EWG), they are also suspected as a culprit for respiratory disorders: “There’s evidence that even healthy people who are [exposed to quats] on a regular basis develop asthma as a result.”
Healthier Choice: You do not really need fabric softener or dryer sheets to soften clothes or get rid of static: Simple vinegar works just as well. “Vinegar is the natural fabric softener of choice for many reasons,” explains Karyn Siegel-Maier in her book The Naturally Clean Home (Storey Publishing, 2008). “Not only is it nontoxic, it also removes soap residue in the rinse cycle and helps to prevent static cling in the dryer.” White vinegar is your best choice for general cleaning; other types can stain.
Alternatives to chemical disinfectants abound, including antibacterial, antifungal tea-tree oil. Mix a few drops of tea-tree oil and a tablespoon of vinegar with water in a spray bottle for a safe, germ killing, all-purpose cleaner. Add a couple of drops of lavender essential oil for scent. The mentioned concoction can also be used as a anti-parasitic spray on animal companions to deter the onset of flea or tick infestations.
5. 2-Butoxyethanol
Found in: Window, kitchen and multipurpose cleaners.
Health Risks: 2-butoxyethanol is the key ingredient in many window cleaners and gives them their characteristic sweet smell. It belongs in the category of “glycol ethers,” a set of powerful solvents that do not mess around. Law does not require 2-butoxyethanol to be listed on a product’s label.
According to the EPA’s Web site, in addition to causing sore throats when inhaled, at high levels glycol ethers can also contribute to narcosis, pulmonary edema, and severe liver and kidney damage. Although the EPA sets a standard on 2-butoxyethanol for workplace safety, Sutton warns, “If you’re cleaning at home in a confined area, like an unventilated bathroom, you can actually end up getting 2-butoxyethanol in the air at levels that are higher than workplace safety standards.”
Healthier Choice: Clean mirrors and windows with newspaper and diluted vinegar. For other kitchen tasks, stick to simple cleaning compounds like Bon Ami powder; it’s made from natural ingredients like ground feldspar and baking soda without the added bleach or fragrances found in most commercial cleansers. You can also make your own formulas with baking soda, vinegar and essential oils. See “DIY Cleaners” for a list of clean concoctions.
As vinegar is of alkalinic in nature, it does not harm our animal companions in any way. In fact it is readily agreeable with the skin pH of dogs and cats.
6. Ammonia
Found in: Polishing agents for bathroom fixtures, sinks and jewelry; also in glass cleaner.
Health Risks: Because ammonia evaporates and does not leave streaks, it is another common ingredient in commercial window cleaners. That sparkle has a price. “Ammonia is a powerful irritant,” says Donna Kasuska, chemical engineer and president of ChemConscious, Inc., a risk-management consulting company. “It’s going to affect you right away. The people who will be really affected are those who have asthma, elderly people with lung issues and animal companions with breathing problems. It is almost always inhaled. People and animals in domestic households who get a lot of ammonia exposure, like domestic helpers and house pets, will often develop chronic bronchitis and asthma.” Ammonia can also create a poisonous gas if it is mixed with bleach.
Healthier Choice: Vodka. “It will produce a reflective shine on any metal or mirrored surface,” explains Lori Dennis, author of Green Interior Design (Allsworth Press, 2010). And toothpaste makes an outstanding silver polish.
7. Chlorine
Found in: Scouring powders, toilet bowl cleaners, mildew removers, laundry whiteners, household tap water.
Health Risks: “With chlorine we have so many avenues of exposure,” says Kasuska. “You are getting exposed through fumes and possibly through skin when you clean with it, but because it is also in city water to get rid of bacteria, you are also getting exposed when you take a shower or bath. The health risks from chlorine can be acute, and they can be chronic; it is a respiratory irritant at an acute level. But the chronic effects are what people do not realise: It may be a serious thyroid disrupter.”
A lot of animal companions actually develop thyroidal disorders from prolonged exposure to chlorine and its derivatives.
Healthier Choice: For scrubbing, stick to baking soda. Toilet bowls can be cleaned with vinegar, and vinegar or borax powder both work well for whitening clothes. So does the chlorine-free oxygen bleach powder available at good supermarkets. To reduce exposure to chlorine through tap water, install filters on your kitchen sink and in the shower. Take note of the water that your animal companions consumed. It is strongly encouraged to pre-boil water that is meant for your animal companions’ consumption.
8. Sodium Hydroxide
Found in: Oven cleaners and drain openers.
Health Risks: Otherwise known as lye, sodium hydroxide is extremely corrosive: If it touches your skin or gets in your eyes, it can cause severe burns. Routes of exposure are skin contact and inhalation. Inhaling sodium hydroxide can cause a sore throat that lasts for days.
Healthier Choice: You can clean the grimiest oven with baking-soda paste — it just takes a little more time and elbow grease (see recipes in “DIY Cleaners” on page 5). Unclog drains with a mechanical “snake” tool, or try this approach from the Green Living Ideas Web site: Pour a cup of baking soda and a cup of vinegar down the drain and plug it for 30 minutes. After the bubbles die down, run hot water down the drain to clear the debris.
Beware of Greenwashing
If a cleaning product at your supermarket proclaims itself “green,” “natural” or “biodegradable,” that does not necessarily mean it is non-toxic.
In 2010 the environmental consulting firm TerraChoice Group produced a report called “The Sins of Greenwashing.” In it the group found more than 95 percent of so-called green consumer products had committed at least one “greenwashing sin,” like making an environmental claim that may be truthful but unimportant. “CFC-free,” for example, is a common one, since CFCs are banned by law.
Donna Kasuska of ChemConscious offers this advice: “When gauging ecological claims, look for specifics. ‘Biodegradable in three to five days’ holds more meaning than “biodegradable” as most substances will eventually break down with enough time.”
DIY Cleaners
Clean your home safely — and cheaply — with the following recipes:
– Basic sink cleanser – Combine ½ cup baking soda with six drops essential oil (such as lavender, rosemary, lemon, lime or orange). Rinse sink well with hot water. Sprinkle combination into sink and pour ¼ cup vinegar over top. After the fizz settles, scrub with a damp sponge or cloth. Rinse again with hot water. (From The Naturally Clean Home, by Karyn Siegel-Maier.)
– Oven cleanser — Put a heatproof dish filled with water in the oven. Turn on the heat to let the steam soften any baked-on grease. Once the oven is cool, apply a paste of equal parts salt, baking soda, and vinegar, and scrub. (From Super Natural Home, by Beth Greer.)
– Bathroom mildew remover – Good ventilation helps prevent mildew and mold. When they do occur, make a spray with 2 cups of water and 1/4 teaspoon each of tea-tree and lavender oil. Shake first and spray on trouble spots. The oils break down the mildew so there is no need to wipe it down. (From Green Interior Design, by Lori Dennis.)
– Carpet shampoo – Mix 3 cups water, ¾ cup vegetable-based liquid soap, and 10 drops peppermint essential oil. Rub the foam into soiled areas with a damp sponge. Let dry thoroughly and then vacuum. (From The Naturally Clean Home.)
– Laundry soap — Try “soap nuts” made from the dried fruit of the Chinese soapberry tree. Available in natural groceries and online, the reusable soap nuts come in a cotton sack that goes into the washing machine with clothes.
– Dusting — Skip the furniture polishes. Instead, use a microfiber cloth. Made from synthetic fibers that are then split into hundreds of smaller microfibres, they capture dust more efficiently than regular rags. If necessary, a little olive oil makes a fine polishing agent.
