Researchers today are beginning to question the safety of many chemicals used in consumer products.

Studies have linked bisphenol A (BPA), flame retardants, phthalates and many other chemicals found in everyday products to a wide range of health problems, including cancer, learning and behavioral problems and reproductive illnesses.

Despite the federal government’s slowness in calling for it, nonprofit labs and for-profit companies alike have been busy developing safer alternatives to some of these harsher chemicals. The brave new world of “green chemistry,” ­in which reducing or eliminating the use or generation of hazardous substances is top priority in the design, use and disposal of products,­ is leading to a rash of new, safer ingredients. Companies looking to put a “BPA-free” sticker on their bottles, for instance, can make them instead with Eastman Tritan copolyester, a plastic alternative that does not disrupt hormones as Nalgene and CamelBak do. Phthalates—used to soften plastic toys—can be replaced with a product called Grindsted Soft-N-Safe, made from acetic acid and castor oil from the castor-oil plant. Formaldehyde adhesives used to make plywood and other wood products can be replaced with soy-based resins, wood fibers and plastic-wood fibers.

The U.S. Environmental Protection Agency supports the effort through its sponsorship of the Presidential Green Chemistry Challenge Awards. The annual awards program recognizes and helps fund efforts to reduce the amount of hazardous substances released into the environment or entering the waste stream, and efforts that reduce the public-health hazards associated with the release of such substances­.
