Formaldehyde is a colorless chemical compound widely used in manufacturing and building materials, including pressed wood products, carpets, and insulation. It can also be found in household products like fabrics and paper towels. Formaldehyde emissions from sources like cigarette smoke and appliances without ventilation systems can cause health problems such as allergies, fatigue, and cancer. Laws and regulations have been passed to reduce the amount of formaldehyde allowed in products.
Formaldehyde is a colorless chemical compound released during the chemical combustion process. It is also a widely used ingredient in the manufacturing sector. There are many formaldehyde-based products, made for both internal and external use.
One of the most common uses of formaldehyde products is in building materials. Pressed wood products, such as particle board, medium density fibreboard, and hardwood plywood panels can all contain formaldehyde. These products are used in flooring, furniture, wall coverings, furniture, drawers and shelving. Of all these, medium density fiberboard is considered to have the highest formaldehyde content.
Pressed wood products, such as oriented or chipboard and softwood plywood, contain phenol-formaldehyde resin. Carpet may also contain formaldehyde within its adhesive backing. Urea-formaldehyde foam insulation, although banned in some areas, has been used to insulate houses.
Other household products can also contain formaldehyde. Durable pressure curtains, formaldehyde glue, and other fabrics, such as clothing and blankets, are sources of the compound. Paper towels, napkins and facial tissues may contain formaldehyde. Formalin, an aqueous solution used as a disinfectant, embalming fluid, and film-stabilizing chemicals are all formaldehyde-based products.
There are also products that simply produce formaldehyde emissions. Cigarette smoke and appliances without ventilation systems, such as kerosene heaters and gas stoves, release formaldehyde into the atmosphere. In combination with sulfuric acid, formaldehyde can also be used as a test kit for the psychoactive drug Methylenedioxymethamphetamine, also known as Ecstasy. Although it cannot identify the drug itself, it can check whether or not other substances used with the drug are present.
Since formaldehyde is a toxic and volatile substance, formaldehyde-based products can be a health concern. Even without directly touching formaldehyde, human beings can still come into contact through the chemical compound during its evaporation into the air or gas leakage. Over time, formaldehyde, like many toxic substances, can be released into the air through outgassing, resulting in the substance being absorbed through breathing.
Some health problems that formaldehyde has been shown to cause in humans include allergies, watery eyes, fatigue, skin rashes, throat irritation, headaches, nosebleeds, asthma, bronchitis, and nasopharyngeal cancer. In light of the health risks associated with formaldehyde products, laws and regulations have been passed to help protect people from harm. In many industries, this legislation has required a complete ban or reduction of the legal amount of formaldehyde allowed in products.
