Quaternium-15 (systematic name: hexamethylenetetramine chloroallyl chloride) is a quaternary ammonium salt that has been used as a surfactant and preservative. It acts as an antimicrobial agent because it slowly releases formaldehyde, which is a preservative with biocidal properties.
Both quaternium-15 and formaldehyde release agents have been the subjects of controversy. They are often banned in US and Europe. [2] [3]
It can be found under a variety of names, including Dow Chemical Company: Dowicil 200 (cis isomer only), Dowicil 75 and Dowicil 100 (both a mix of cis and trans isomers).
Quaternium-15 can be prepared by treating hexamethylenetetramine with 1,3-dichloropropene. A mixture of cis and trans isomers are produced.[ citation needed ]
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, and glues and adhesives.
Quaternium-15 has been banned in the EU since 2017 and a bill was introduced in the US in 2017 to require the FDA to investigate its safety. [4] [5]
Quaternium-15 is an allergen, and can cause dermatitis. [6] Many of those with an allergy to quaternium-15 are also allergic to formaldehyde. At low pH values, 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. [7] It is the single most often found cause of allergic contact dermatitis of the hands (16.5% in 959 cases). [8] In 2005–06, it was the fourth most prevalent allergen in patch tests (10.3%). [9]
Although quaternium-15 releases low amounts of formaldehyde. [10] Even so, Johnson & Johnson announced plans to phase out its use of quaternium-15 in cosmetic products by 2015 in response to consumer pressure. [11] [12]
