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’re particularly concerned because they don’t want us overusing antibacterial chemicals — that’s 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’re hooked on hand sanitizer, choose one that is alcohol-based and without triclosan.
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’re 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’re 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 don’t 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.
