This Amendment No. 8 (this "Amendment") amends and supplements the Schedule 13D filed on December 20, 1989, as previously amended (the "Schedule 13D"), of Henkel KGaA ("KGaA") and HC Investments, Inc. ("HCI"), with respect to the Common Stock, par value $1.00 per share ("Common Stock"), of Ecolab Inc. ("Ecolab" or the "Company"). All capitalized terms used in this Amendment and not otherwise defined herein have the meanings ascribed to such terms in the Schedule 13D. Item 4. Purpose of Transaction. On November 30, 2001, Henkel and Ecolab completed the Proposed Sale. In connection with the closing of the Proposed Sale, the parties executed the Proposed Amended Stockholder's Agreement, in the form previously filed as an Exhibit to, and described in, Amendment No. 5 to the Schedule 13D (which shall be referred to as the "Amended Stockholder's Agreement"). Henkel intends to continue to review its investment in Common Stock from time to time and, depending upon certain factors, including without limitation the financial performance of Ecolab, the availability and price of shares of Common Stock on the open market, Henkel's overall relationship with Ecolab, and other general market and investment conditions, Henkel may determine to acquire through open market purchases or otherwise additional shares of Common Stock, or, based upon such factors, to sell shares of Common Stock, from time to time, in each case to the extent permitted under the Amended Stockholder's Agreement and applicable law. Except as set forth herein, Henkel has no current plans or proposals that relate to or would result in any of the actions or events enumerated in clauses (a) through (j) of Item 4 of Schedule 13D, as promulgated by the Securities and Exchange Commission. Signature After reasonable inquiry and to the best of our knowledge and belief, we certify that the information set forth in this statement is true, complete and correct.
