Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O.
As a result, formaldehyde content in precipitation can range from 110 μg to 1380 μg per liter. [6] These concerns notwithstanding, according to the American Chemistry Council, formaldehyde, as a ubiquitous chemical produced by living beings, is eminently biodegradable by both sunlight in air and bacteria in soil and water.

To the average consumer, formaldehyde may be best known as an embalming agent. But this naturally occurring chemical is a major industrial staple, used in many consumer goods, including cleaning ...
CDC's Disinfection and Sterilization list of Chemical Disinfectants mentions and discusses substances such as: alcohol, chlorine and chlorine compounds, formaldehyde, glutaraldehyde, hydrogen peroxide, iodophors, ortho-phthalaldehyde (OPA), peracetic acid, peracetic acid and hydrogen peroxide, phenolics, quaternary ammonium compounds, with ...
Disinfection of a floor using disinfectant liquid applied using a mop. Levels of resistance of microbes to disinfectants. A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. [1]
Formaldehyde is less expensive and has a much longer shelf-life if some methanol is added to inhibit polymerization of the chemical to paraformaldehyde, but is much more volatile. Formaldehyde is also used as a gaseous sterilizing agent; in this case, it is prepared on-site by depolymerization of solid paraformaldehyde.
A lower molar ratio of formaldehyde decreases the emission of free formaldehyde from UF products. There is a significant decrease in formaldehyde emissions from UF-based particleboard from F/U molar ratio of 2.0 to 1.0. The German standard for UF resins require the F/U molar ratio to be below 1.2. The U.S. NPA standard is an F/U molar ratio ...
In addition to being an allergen, it is a formaldehyde releaser, since it generates formaldehyde slowly as it degrades. Although the formaldehyde acts as a bactericidal preservative, it is a known carcinogen. In 2005–06, it was the 14th-most-prevalent allergen in patch tests (3.7%). [4]
