The company was founded in 1928 as the National Aluminate Corporation, formed from the merger of Chicago Chemical Company and the Aluminum Sales Corporation. By a series of mergers and acquisition, its name was changed to Nalco Chemical Company (1959 - 1999); then Ondeo Nalco Company (1999 - 2004); and in 2004 to Nalco Holding Company. It became a subsidiary of Ecolab Inc. in December 2011 after the completion of the US$5.4 billion acquisition by Ecolab.[2][3]

Nalco Water serves more than 70,000 customers employing over 11,500 employees operating in over 130 countries.[citation needed] Among its products is Corexit - an oil dispersant widely used in the Deepwater Horizon oil spill.


The company traces its origins to 1928 in the United States with the establishment of National Aluminate Corporation - formed from the merger of Chicago Chemical Company and the Aluminum Sales Corporation.[4] In 1959 it changed its name to Nalco Chemical Company; and in 1964, it became a publicly traded company listed on the New York Stock Exchange. It acquired Industrial Bio-Test Laboratories in 1966, and the marine business from Bull & Roberts (now Waltron) in 1984.

The company was delisted from NYSE and renamed to Ondeo Nalco Company, following its 1999 acquisition by the French company, Suez (presently GDF Suez).[5]

On 9 December 2003, the private equity group consisting of the Blackstone Group, Apollo Management LP and Goldman Sachs Capital Partners collaborated to acquire Ondeo Nalco Company from Suez SA for US$4.2 billion.[6] The Company went public again, returning to the New York Stock Exchange in late 2004 under the name Nalco Holding Company.

In 2007, Nalco Water achieved sales of more than US$3.9 billion.

In July 2011, Nalco Water announced a merger with Ecolab, Inc., and it became a wholly owned subsidiary of Ecolab Inc. in December 2011 after the completion of the US$5.4 billion acquisition by Ecolab.[7][2][8][3]

ExxonMobil tiesEdit

In 1994, Nalco Water and Exxon Chemical Company announced the formation of the joint venture, Nalco Exxon Energy Chemicals L.P., to provide products and services to all facets of the petroleum and natural gas industries. In 2001, NALCO, which by then named 'Ondeo Nalco', strengthened its position in the petroleum industry when Nalco Exxon Energy Chemicals, L.P. became part of the company through redemption of ExxonMobil stock in the joint venture. Daniel S. Sanders, who was previously president of Exxon Mobil Chemical Company, a subsidiary of Exxon Mobil; serves on Nalco's (now, Ecolab's) board.[9][10]
