(1945) The reactions of formaldehyde withamino acids and proteins.

Photolysis and reaction with hydroxyl radicals rapidly removeformaldehyde from the atmosphere.

Mechanism of the initial reaction of formaldehydewith DNA.

Patch tests performed with formaldehyde challenge concentrations of< 1% formaldehyde resulted in positive reactions in about 2% of allpatch-tested patients throughout the world.

Formaldehyde that escapes metabolism can react withmacromolecules at the site of entry.

(1979) Reaction of formal-dehyde with calf-thymus nucleohistone.

These react with OH radicals and ozone toform formaldehyde and/or other aldehydes as intermediates in a seriesof reactions that ultimately lead to the formation of carbon monoxideand dioxide, hydrogen, and water (Zimmermann et al., 1978; Calvert,1980).

Irritant skin reactions occur through direct contact with formal-dehyde solutions.

A simple colour reaction for the identification of urea formalde-hyde resins and diisocyanates, carried out on the surface of wood-basedpanels, has been described by Schriever (1981).

Hantzsch pyridine synthesis | Wiki | Everipedia

Allergic reactions to cosmetics containing formaldehyde as a pre-servative, especially shampoos, are unusual (Eckardt, 1966) and appearmostly among those who have been sensitized by occupational exposure.

Learning from the Hantzsch synthesis

An allergic contact dermatitis reaction was provoked by a dose offormaldehyde of 0.25 µg/cm2 skin (challenge dose: 50 µg/cm2 with0.5% percutaneous penetration).

Patch tests performed with formaldehyde challenge concentrations of1% or less resulted in positive reactions in about 2% of all patientstested throughout the world; higher formaldehyde challenge concen-trations may be irritant (Anon., 1987).

Hantzsch pyrrole synthesis - Wikipedia

Formaldehyde solution is a primary skin-sensitizing agent inducingallergic contact dermatitis (Type IV, T-cell mediated delayed hypersen-sitivity reaction); it may induce immunological contact urticaria(Type I, perhaps IgE mediated, immediate hypersensitivity reaction).

Hantzsch pyrrole synthesis - Revolvy

Marzulli & Maibach (1973) reported that one of 5 sen-sitized volunteers reacted, under controlled conditions, to a challengeconcentration of 0.01% formaldehyde.
