Lisa Rowley started using "green" cleaning products when she became a mom.

"I use a floor cleaner, I use stuff for my wood, stuff for my dishwasher, laundry detergent," she said. "I know when I'm cleaning my wood, it's good natural stuff."

But how do you know products labeled "natural" or "ecological" really are?

"Consumers really should not rely on labels. Often these terms can be used by the manufacturer without any verification or oversight or indeed without meeting any particular standards," said Urvashi Rangan of the Consumers Union.

It turns out those new 'eco terms' you are seeing more of aren't regulated or defined by the government. And cleaning manufacturers aren't even required to list their ingredients on the label.

Jeffrey Hollender wants to change that. He works for an eco-cleaning company called Seventh Generation. They choose to list their ingredients.

"It makes absolutely no sense that the manufacturers of cleaning products are allowed to keep secret what they put in the bottle," he said.

But the Soap and Detergent Association says it should be up to each company to design its label.

"If you overload your label with so much information, the really meaningful information becomes irrelevant. The critical information on that label is certainly the safety and use information," said Brian Sansoni.

Rowley was disappointed to see some of the green products she bought don't list the ingredients.

"I was kind of shocked. So, I might not be using that product anymore," she said.
