It is very important to read the product label for harmful chemicals. However, manufacturers are only obligated to include chemicals of “known concern” on their labels. According to the EPA, of the nearly three thousand top selling chemicals in the U.S., only 7 percent have a full set of basic toxicity information. And, although many products are labeled green, gentle, organic or eco-friendly, that does not necessarily mean safer, either. These products still often contain harmful chemicals and scents that can cause the same issues as any regular cleaning product.
