Greener cleaners go mainstream

In January, the Clorox Company launched Green Works (shown), a line of what it claims are "natural" cleaners. Days later, SC Johnson announced that a new Greenlist label would appear on its familiar blue Windex glass cleaner. Both products are now being rolled out into retailers nationwide. You know the green bandwagon is getting crowded when two behemoths of the household-cleaning industry climb aboard.

No sooner had the companies launched the products than some in the green blogosphere began questioning the safety of the ingredients used in these cleaners and whether they really are just more examples of greenwashing. So we decided to take a closer look.

Clorox Green Works
Clorox says that its Green Works products, which include all-purpose, bathroom, dilutable, glass-and-surface, and toilet-bowl cleaners, are at least 99 percent "natural." But without a nationally accepted standard definition for that term, the company is using its own. Natural cleaners, Clorox says, are defined as having ingredients that come from primarily plant and mineral materials and contain less than 1 percent petrochemicals. But keep in mind, natural doesn't necessarily mean nontoxic or nonirritating.

Unlike with many other cleaners, including some from Clorox, you will find a complete list of ingredients on Green Works packaging. That's significant, since full disclosure is not required by federal law. At the same time, since it can be difficult to judge the potential harmful effects of ingredients you might be unfamiliar with, if you're concerned about your health and safety, check for warning labels; they are required when a product contains ingredients that are known to cause harm to humans. Four out of five Green Works products carry "caution" labels, which indicate relatively less hazard than "danger" or "poison" labels would.

Four Green Works products carry the U.S. Environmental Protection Agency's Design for the Environment, or DfE, label (shown). The presence of the label means that the EPA evaluated the ingredients for health and environmental impacts. But it doesn't signify that the ingredients are harmless; rather the label indicates that they are considered to be the least harmful in their chemical class. Also, since ingredients are judged individually, there is not one clear standard that all products with a DfE label must meet. Consumer Reports is in the process of evaluating the DfE label.

In April, a Sierra Club label will also appear on all the Green Works products. The label will indicate that the products have been reviewed by the club and are environmentally preferable to conventional products. However, the label is not free from conflict-of-interest, as the Sierra Club will receive financial support from Clorox as part of this partnership.

SC Johnson Greenlist
SC Johnson's Windex Original blue glass cleaner is the first product to carry the company's Greenlist label. However, the manufacturer claims it has been reformulating several of its products in accordance with the Greenlist process since 2001. Since the company defined the process, it decides what's green. Basically, with Greenlist, ingredients are ranked on a more-to-less impact scale from 0 to 3. That information is then used to improve the "environmental and health profile" of products by reformulating them with ingredients considered by the company to be less harmful.

For the Windex, SC Johnson says it replaced a 0-rated solvent with a more environmentally responsible material and reduced the levels of volatile organic compounds in the cleaner. VOCs, chemicals found in many household products, can cause dizziness, headaches, and other acute symptoms.

Unfortunately, you won't be able to find a complete list of ingredients on Greenlist products since the company is not required by federal law to disclose all the ingredients used. Without this information, it's impossible for us to tell whether the green or any other claims are true.

SC Johnson also carries cleaning products with the DfE label, indicating they have gone through the government's screening process for health and environmental impacts. Those products include Shout Trigger laundry stain remover and Citrus Action, Scrubbing Bubbles Soap Scum Remover with Orange Action, Shower Shine Daily Shower Cleaner, and Fantastik Oxy Power multipurpose cleaner.

In the end, the best way to find eco-friendly cleaners—from Clorox, SC Johnson, or any other manufacturer—is to look for products with labels that have been independently verified as green in the Eco-labels Center on GreenerChoices.org.
