A saturated water solution, of about 40% formaldehyde by volume or 37% by mass, is called "100% formalin". A small amount of stabilizer, such as methanol, is usually added to suppress oxidation and polymerization. A typical commercial-grade formalin may contain 10–12% methanol in addition to various metallic impurities.
A mixture of these chemicals is known as embalming fluid and is used to preserve bodies of deceased persons for both funeral purposes and in medical research in anatomical laboratories. The period for which a body is embalmed is dependent on time, expertise of the embalmer and factors regarding duration of stay and purpose.
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 ...
The American Cancer Society states that although quaternium-15 releases formaldehyde, a known carcinogen in laboratory test animals at relatively high doses, because the amount of formaldehyde released from these products is low, it is unclear that avoiding quaternium-15 in cosmetics provides any health benefits.

The Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...
Formaldehyde is a known carcinogen, for instance being associated with nasopharyngeal cancer and leukemia. [14] [20] [39] This compound also occurs in small amounts as a contaminant in alcoholic beverages, and is chemically similar to the carcinogenic ethanol (alcohol) metabolite acetaldehyde.
"Dripping", where the liquid is dripped directly onto the atomizer, could yield a higher level of nicotine when the liquid contains nicotine, and also a higher level of chemicals may be generated from heating the other contents of the liquid, including formaldehyde. [82] Dripping may result in higher levels of aldehydes. [83]
The analysis, published in the journal Frontiers in Toxicology, builds upon research published earlier this year, which identified more than 900 chemicals as being potential mammory carcinogens ...
