The other part of the merger, the KZO, was formed when Koninklijke Zout Ketjen merged with Koninklijke Zwanenberg Organon in 1967. The former was itself a merger of Koninklijke Nederlandse Zoutindustrie (KNZ) and Ketjen. The KNZ was formed in 1918 by Ko Vis as a salt producing company; a business that to this day plays an important role in AkzoNobel's activities. The other part, Koninklijke Zwanenberg Organon, was formed when Zwanenberg's Fabrieken (est. 1887), a meat export factory based in Oss merged with Organon, a pharmaceuticals company founded by Saal van Zwanenberg, also in Oss.
