Working across the spectrum of pharmaceuticals and consumer health, chemicals and food additives, production systems and equipment, we are a human healthcare company that actively participates with, and contributes to, any healthcare system. We place primary emphasis on patients and their families, and observe the highest legal and ethical standards in our business activities.
