Quaternium-15 (systematic name: hexamethylenetetramine chloroallyl chloride) is a quaternary ammonium salt used as a surfactant and preservative in many cosmetics and industrial substances. It is an anti-microbial agent by virtue of being a formaldehyde releaser, however this can also cause contact dermatitis, a symptom of an allergic reaction, especially in those with sensitive skin.
It can be found under a variety of names, most commonly those of the Dow Chemical Company: Dowicil 200 (cis isomer only), Dowicil 75 and Dowicil 100 (both a mix of cis and trans isomers).
The isolated cis-compound is used primarily in cosmetic applications, with a maximum permitted concentration in the EU of 0.2%. The mixed product (cis- and trans-) is used in a wider range of formulations such as: emulsifiable metal-cutting fluids; latex and emulsion paints; liquid floor polishes and floor waxes; glues and adhesives.
Quaternium-15 is an allergen, and can cause contact dermatitis in susceptible individuals. Many of those with an allergy to quaternium-15 are also allergic to formaldehyde. At low pHs it would be expected to release significant amounts of formaldehyde due to acid hydrolysis via the Delepine reaction.
Allergic sensitivity to quaternium-15 can be detected using a patch test. It is the single most often found cause of allergic contact dermatitis of the hands (16.5% in 959 cases). In 2005–06, it was the fourth-most-prevalent allergen in patch tests (10.3%).
Some consumer cosmetics contain quanternium-15 for its antimicrobial properties. The American Cancer Society states that although quanternium-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 quanternium-15 in cosmetics provides any health benefits. Even so, Johnson & Johnson announced plans to phase out its use of quanternium-15 in cosmetic products by 2015 in response to consumer pressure.
