Quaternium-15, a preservative, is one of the most used substances and is added to several cosmetics and other industrial products. Quaternium-15 is a mixture of
isomers, where the cis-form is the dominant form and where the trans-form is the minor
component present as an impurity.
Quaternium-15 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%. DOWICIL 200 preservative (cis form) is used primarily as a preservative in a wide variety of personal-care
and cosmetic products. It is designed to provide highly effective broad-spectrum antimicrobial
activity, especially in water-based formulations. It is used in both leave-on and rinse-off
application such as baby-care products, hair-care products, lotions, powders, and creams.
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. Recently, the cis-form has been classified as a CMR substance with the classification
toxic to reproduction, category 3. This classification only concerns the cis-isomer:
