Name that company

Back in 1833, two men — a miller and a druggist who grew herbs — decided to make and sell drugs and essential oils. Their company ended up a part of me, along with many others. I got my current name after the 1958 merger between Polak & Schwarz and van Ameringen-Haebler. Today, based in New York City and with a market value recently near $13 billion, I’m a worldwide force in scents, tastes and ingredients. In 2019 I raked in $5.1 billion from about 38,000 customers. I’m merging with DuPont’s Nutrition & Biosciences division. Who am I?
