This Amendment No. 13 (this "Amendment") amends and supplements the Schedule 13D filed on December 20, 1989, as previously amended (the "Schedule 13D"), of Henkel KGaA ("KGaA" and, together with its affiliates, "The Henkel Group") and HC Investments, Inc., 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 2. Identity and Background. ----------------------- The Schedule 13D is now no longer filed by Henkel Chemie Verwaltungsgesellschaft mbH ("Chemie"). As described in this Amendment, effective September 21, 2005, Chemie transferred back to KGaA the 43,359,224 shares of Common Stock it previously held and no longer holds any interest in the Common Stock. The names, addresses, occupations and citizenship of the executive officers and members of the board of directors, or equivalent body, of each of KGaA and Henkel Corporation are set forth in Schedule I hereto. None of KGaA, Henkel Corporation or, to the best of their knowledge, Henkel of America, Inc. or any of the persons listed on Schedule I hereto has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to federal or state securities laws or finding any violation with respect to such laws. Item 4. Purpose of Transaction. ---------------------- As noted above, effective September 21, 2005, Chemie transferred all 43,359,224 shares of Common Stock it previously held to KGaA. The transfer was effected for internal organizational purposes of the The Henkel Group. There is no change to the plans or intentions of KGaA and its respective subsidiaries with respect to Ecolab, and no other change occurred in the relationship of any member of The Henkel Group with Ecolab. In August 2005, Jochen Krautter retired from the Ecolab Board. In accordance with the Amended Stockholder's Agreement, Kasper Rorsted, Executive Vice President for Human Resources, Logistics, Information Technologies and Infrastructure Services of KGaA, was appointed to the Ecolab Board. Currently, Ulrich Lehner, Stefan Hamelmann and Mr. Rorsted serve as members of the Ecolab Board pursuant to the Amended Stockholder's Agreement. KGaA 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, KGaA's overall relationship with Ecolab, and other general market and investment conditions, KGaA may determine either 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, KGaA and Henkel Corporation have 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. Item 5. Interest in Securities of the Issuer. ------------------------------------ (a)-(b) At the date hereof, in the aggregate, the 72,692,552 shares of Common Stock owned by KGaA and Henkel Corporation represent approximately 28.4% of the 255,748,469 shares of Common Stock reported by Ecolab in its Quarterly Report on Form 10-Q to be outstanding as of July 31, 2005. Of that total, Henkel Corporation directly beneficially owns 29,333,328 shares of Common Stock (approximately 11.5% of such total). Henkel Corporation and, by virtue of its indirect control of Henkel Corporation, KGaA share the power to vote and the power to dispose of these shares of Common Stock (subject to the provisions of the Amended Stockholder's Agreement). KGaA directly beneficially owns the remaining 43,359,224 shares of Common Stock (approximately 16.9% of such total). KGaA has the sole power to vote and to dispose of these shares of Common Stock (subject to the provisions of the Amended Stockholder's Agreement). (c) Except for the transfer of Common Stock by Chemie to KGaA as described herein, no transactions in shares of Common Stock were effected during the past 60 days by Chemie, Henkel Corporation or KGaA, or, to the best of their knowledge, by Henkel of America, Inc. or any of the other persons listed on Schedule I.
