 The Nalco Foundation are paid by the Company.


DESCRIPTION OF CAPITAL STOCK

	Common Stock
	
	The record holders of Common Stock are entitled, ratably, to such dividends
 thereon as the Company's Board of Directors in its discretion may declare
 out of funds legally available therefore; are entitled to receive pro rata
 all assets of the Company available for distribution to stockholders in the
 event of liquidation of the Company; are entitled to one vote for each share 
held; and have no preemptive rights to purchase or subscribe for any stock of 
the Company now or hereafter authorized or securities convertible into Common
Stock.  All outstanding shares of Common Stock, including the shares offered
hereby,
 are fully paid and non-assessable.  There is no charter restriction on the
 repurchase by the Company of shares of its own stock.

	Preferred Stock

	The Company's Restated Certificate of Incorporation permits the Board of 
Directors of the Company, without further stockholder approval, to authorize 
the issuance of up to 2,000,000 shares of Preferred Stock, $1.00 par value,
 and to fix the various rights, preferences, terms and provisions of each 
series of Preferred Stock so issued.  No such Preferred Stock has been issued 
other than Series B ESOP Convertible Preferred Stock (the "ESOP Stock"), of
 which 415,800 Shares were issued to the Northern Trust Company as Trustee of 
the Nalco Chemical Company Employee Stock Ownership Plan (the "ESOP").  These
are subject to restrictions on transfer set forth in the Certificate of
 Designations relating to the ESOP Stock and a stock purchase transfer agreement
 dated May 15, 1989.  The shares are convertible into the Company's Common
 Stock in a 20-1 ratio with the number of votes per share of ESOP stock equal to
 the shares of Common Stock into which the ESOP Stock can be converted. 
 Except with respect to the preferred share purchase rights described below,
 there are presently no understandings, agreements, negotiations or discussions
which will or might involve the possible issuance of Preferred Stock for any 
purpose.


	Preferred Share Purchase Rights

	On July 24, 1986, the Company's Board of Directors declared a dividend of
 certain preferred share purchase rights on each outstanding share of Common
 Stock.  The Company will issue similar rights with respect to newly-issued
 shares of Common Stock as long as the rights are attached to Common Stock.
  The rights, which are not exercisable until certain events involving a 
potential takeover occur, are more particularly described in the Company's 
Registration Statement on Form 8-A, filed with the Commission on August 1, 1986,
and Forms 8 and 8-K, filed with the Commission on July 6, 1989, which are
incorporated herein by reference.

VALIDITY OF THE SHARES

	The validity of the shares offered hereby will be passed upon for the Company
 by Suzzanne J. Gioimo, Corporate Secretary, of the Company.  Suzzanne J. Gioimo
 is the beneficial owner of 3,107 shares of Common Stock and has options under 
the Company's 1982 and 1990 stock option plan to acquire an additional 8,200
 shares of Common Stock.

EXPERTS

	The consolidated financial statements as of December 31, 1993 and for the 
year then ended incorporated by reference in this Prospectus have been so 
incorporated in reliance on the report of Price Waterhouse LLP, independent 
accountants, given on the authority of said firm as experts in auditing and
 accounting.  The consolidated financial statements as of December 31, 1992
 and for each of the two years in the period ended December 31, 1992
 incorporated by reference in this Prospectus have been so incorporated in
reliance on the report of Ernst & Young LL, independent auditors, given on the
authority of said firm as experts in auditing and accounting.

	With respect to the unaudited consolidated financial information of the
 Company for the three, six and nine-month periods ended March 31, June 30 and
 September 30, 1994, incorporated by reference in this Prospectus, Price 
Waterhouse LLP reported that they have applied limited procedures in
 accordance with professional standards for a review of such information.
  However, their separate reports dated April 20, July 29 and October 24, 1994,
 incorporated by reference states that they did not audit and they do
not carried out any significant or additional audit tests beyond those which
 would have been necessary if their report had not been included.  Accordingly,
 the degree of reliance on their report on such information should be restricted
 in light of the limited nature of the review procedures applied.  Price 
Waterhouse LLP is not subject to liability provisions of section 11 of the 
Securities Act of 1933 for their report on the unaudited consolidated financial
 information because that report is not a "report" or a "part" of the 
registration statement prepared or certified by Price Waterhouse LLP within
the meaning of sections 7 and 11 of the Act.

	Total                          	$11,000

 circumstances, requires, indemnification of officers, directors and
 employees of the Company.
(b) Article Sixth of the Certificate of Incorporation of the Company requires

extent permitted by law.

 certain liabilities pursuant to the Securities Act of 1933.
Item 16. Exhibits and Financial Statement Schedules.
See Exhibit Index included herewith which is incorporated herein by reference.


Item 17. Undertakings.
	-	The undersigned registrant hereby undertakes:
	(a)	To file, during any period in which offers or sales are being made, a
 post-effective amendment to this registration statement:
	(i)	To include any prospectus required by section 10(a)(3) of the Securities 
Act of 1933;
	(ii)	To reflect in the prospectus any facts or events arising after the 
effective date of the
registration statement (or the most recent post-effective amendment thereof)
 which,
individually or in the aggregate, represent a fundamental change in the
 information set
forth in the registration statement;
	(iii)	To include any material information with respect to the plan of 
distribution not previously disclosed in the registration statement;
Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the
 registration statement is on Form S-3 or Form S-8, and the information
 required to be included in a post-effective amendment by those paragraphs
 is contained in periodic reports filed by the registrant pursuant to section 13
 or section l5(d) of the Securities Exchange Act of 1934 that are incorporated 
by reference in the registration statement.
	(b)	That, for the purpose of determining any liability under the Securities 
Act, each such post
effective amendment shall be deemed to be a new registration statement
 relating to the securities
offered therein, and the offering of such securities at that time shall be 
deemed to be the initial
bona fide offering thereof.
	(c)	To remove from registration by means of a post-effective amendment any
 of the securities being
registered which remain unsold at the termination of the offering.
The undersigned registrant hereby undertakes that, for purposes of determining 
any liability under the Securities Act, each filing of the registrant's annual
 report pursuant to Section 13(a) or Section l5(d) of the Exchange Act that is 
incorporated by reference in this registration statement shall be deemed to
 be a new registration statement relating to the securities offered therein,
 and the offering of such securities at that time shall be deemed to be the 
initial bona fide offering thereof.
Insofar as indemnification for liabilities arising under the Securities Act 
may be permitted to directors, officers and controlling persons of the
 registrant pursuant to the provisions set forth or described in Item 15 of 
this Registration Statement, or otherwise, the registrant has been advised 
that in the opinion of the Securities and Exchange Commission such 
indemnification is against public policy as expressed in the Securities Act
 and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a
director, officer or controlling person of the registrant in the successful
 defense of any action, suit or proceeding) is asserted by such director,
 officer or controlling person in connection with the securities being
 registered, the registrant will, unless in the opinion of its counsel the
 matter has been settled by controlling precedent, submit to a court of
 appropriate jurisdiction the question whether such indemnification by it is
 against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.



SIGNATURES
Pursuant to the requirements of the Securities Act, the Company certifies that 
it has reasonable grounds to believe that it meets all the requirements for
 filing on Form S-3 and has duly caused this Registration Statement to be
 signed on its behalf by the undersigned, thereunto duly authorized, in the
 City of Naperville and State of Illinois on the 19th day of January, 1995.

Ladies and Gentlemen:

I am representing Nalco Chemical Company (the "Company") in connection with
 the registration under the Securities Act of 1933 of 226,065 shares of 
common stock, par value $0.1875 per share ("Common Stock"), of the Company
 transferred by the Company as Corporate gifts to The Nalco Foundation and 
the North Carolina State University Endowment Fund (the "Selling Stockholders").
In connection therewith, I have examined or am otherwise familiar with such
 documents and instruments as I have deemed necessary for the purposes of this
opinion.  Based upon the foregoing, I am of the opinion that the transfer has
been duly
authorized by the Board of Directors of the Company and the Selling 
Stockholders have obtained legally issued, fully paid and non-assessable
 shares of Common Stock.

I hereby consent to the filing of this opinion as an exhibit to the subject
 Registration Statement.

Very truly yours,
