National Institute of Health provides a database of commercial household products. Ever wonder what is in that air freshener you just bought, but the print was too small to read without a magnifying glass. Or what is in your laundry, kitchen, or bath soap? How about the laser toner cartridge or the pen in your pocket?
Most of the listings also provide toll free numbers to the manufacturer. The date when the information was last verified. Health warnings that will effect you, your children, or pets.
