In 1900 Dow Chemical was incorporated combining the bulk of its assets from Dow Midland, and in 1920 began the production of phenol magnesium. Phenol Magnesium would be used for munitions during World War I. Dow has produced a multitude of chemicals throughout various wars, including mustard gas, napalm, and Agent Orange. The production of these chemicals led to law suits from veterans. These lawsuits coupled with the lawsuits against Dow Corning, one of the producers of silicon Brest implants, are what led to Dow's bankruptcy in 1995.
After the bankruptcy was over Dow acquired Rhom & Hass, a manufacturer of specialty chemicals for end users, in 2009 following the purchase of Union Carbide in 1999. Edging its way closer to becoming one of the largest chemical producers in the world, the Dow and Dupont merger in 2017 made the union the largest producer in the world at the time.
After the split of Dow and Dupont in 2019, Dow still remains one of the dominate forces in chemical production. Dow is currently a leading producer of synthetic fibers,plastic and chemicals, and is still a driving factor in the research and development of the chemical world, despite its separation from Dupont.
