Corporate Whitewash?: Why Do Cleaning Product-Makers Keep Most of Their Ingredients Secret?

Although some manufacturers are more transparent about their ingredients, makers are only required by the EPA to list those that are active disinfectants or potentially harmful.

Since cleaning products aren’t food, beverages or drugs meant to be ingested, they aren’t regulated, per se, by the U.S. Food and Drug Administration. However, makers are required by the U.S. Environmental Protection Agency (EPA) to list ingredients that are active disinfectants or potentially harmful. Otherwise, they usually keep their other ingredients secret, presumably so competitors can’t copy their formulas.

But consumer advocate Sloan Barnett, author of Green Goes with Everything, doesn’t give manufacturers the benefit of that doubt. “Call me suspicious, but I honestly don’t think it’s because the recipe is top secret,” she says. “If it was, there wouldn’t be so many competing products with identical ingredients.” Barnett thinks manufacturers don’t want to scare off consumers by disclosing how many potentially harmful chemicals are flying under the EPA’s radar in their products.

“The government only requires companies to list ‘chemicals of known concern’ on their labels. The key word here is ‘known’,” she says. “The fact is that the government has no idea whether most of the chemicals used in everyday cleaning products are safe because it doesn’t test them, and it doesn’t require manufacturers to test them either.”

She adds that the EPA, under the terms of 1976’s Toxic Substances Control Act, “can’t require chemical companies to prove the safety of their products unless the agency itself can show that the product poses a health risk—which the EPA does not have the resources to do since, according to one estimate, it receives some two thousand new applications for approval every year.” She cites a recent study by the non-profit Environmental Working Group, which found that the EPA approved most applications within three weeks even though more than half provided no information on toxicity whatsoever.

Regardless, consumers should be familiar with what warning labels are on cleaning products. “All household cleaners that contain known hazardous chemicals must carry a warning label that spells out potential risks, along with precautionary steps and first-aid instructions,” reports Consumer Reports’ Greener Choices website.

Some manufacturers are beginning to be more transparent about their ingredients. The Clorox Company, for example, one of the largest manufacturers of cleaning products, now publishes full lists of the ingredients for all of its brands on its corporate responsibility website, CloroxCSR.com. Many praise Clorox for doing so; others argue that, whether or not ingredients are disclosed, the company—like many others—is still in the business of making products that pose health and environmental hazards.

Generally speaking, if you’re looking for safer alternatives, browse the cleaning products sections of natural foods markets such as Whole Foods, which are populated with lesser-known but more green-friendly brands. For do-it-yourselfers, the Greener Choices website also lists recipes for eco- and health-friendly homemade household cleaners using ingredients like baking soda, borax, lemon juice and vinegar.
