KOSTER KEUNEN
There aren’t many businesses that can say they are in their fifth generation. For John Koster, president of Koster Keunen Manufacturing, located in Watertown, CT, there is a sense of responsibility to make it to the sixth and seventh generations. Established by newlyweds Johanna Keunen and Bernhard Koster in Holland in 1852, Koster Keunen has been a world leader in natural wax for over 160 years. Their refined waxes can be found in cosmetics, automotive applications, pharmaceuticals and inks, to name just a few.
