Consumers seeking a greener clean can start by looking for labels that
list all ingredients (not just active ingredients). A few certifying
organizations put their stamp of approval on products that meet their
own eco-friendly criteria. The organizations — and the standards for
products bearing their logo:EcoLogo: Doesn't contain alkylphenol exothylates or glycol ethers, chemicals that cause cancer or harm the reproductive system, or ingredients that can deplete the Earth's ozone layer.
Green Seal: Doesn't contain chemicals that cause cancer, harm the reproductive system, irritate the skin or eyes, or persist in the environment. Can contain only a limited amount of phosphates. Packaging must contain recycled materials and be recyclable.
Design for the Environment: Was developed in partnership with the Environmental Protection Agency to contain less polluting ingredients. Detergents, for example, can't contain nonylphenol ethoxylates.
