In enzymology, a formaldehyde dehydrogenase (EC 1.2.1.46) is an enzyme that catalyzes the chemical reaction formaldehyde + NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } formate + NADH + H + The 3 substrates of this enzyme are formaldehyde , NAD + , and H 2 O , whereas its 3 products are formate , NADH , and H + .
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]
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 precise mechanism by which altretamine exerts its anti-cancer effect is unknown but it is classified by MeSH as an alkylating antineoplastic agent. [5] This unique structure is believed to damage tumor cells through the production of the weakly alkylating species formaldehyde, a product of CYP450-mediated N-demethylation. Administered ...
Reactions between aldimines and α-methylene carbonyls are also considered Mannich reactions because these imines form between amines and aldehydes. The reaction is named after Carl Mannich. [2] [3] Scheme 1 – Ammonia or an amine reacts with formaldehyde and an alpha acidic proton of a carbonyl compound to a beta amino carbonyl compound.
A wide range of studies have linked formaldehyde to certain cancers, including uterine cancer and blood cancer. Some companies have responded by developing formaldehyde-free formulas or by clearly ...
The Environmental Protection Agency (EPA) has determined that breathing in formaldehyde, a chemical that’s used in building materials and hair straighteners, can cause cancer. In a toxicological ...
