Formaldehyde is a gas, formed during combustion, as part of various industrial processes, or, to a lesser extent, by many plants and animals. Manufactured products that may contain formaldehyde include resins, carpets, cleaning agents, cosmetics, paints, particle board, plywood, and other products.

Unfortunately, formaldehyde can have adverse health effects. U.S. EPA classifies it as a probable human carcinogen, and the International Agency for Research on Cancer classes it as a carcinogen.
