                 KYZEN CORPORATION REPORTS FIRST QUARTER RESULTS


                      Third Consecutive Profitable Quarter;
                  Solid Year-Over-Year Increases in Net Income

NASHVILLE, TN (April 17, 2003) . . . . Kyzen Corporation (OTCBB: KYZN.OB), a
specialty chemical company and a leading provider of products and processes for
precision cleaning applications in high-technology manufacturing environments,
today announced results for the quarter ended March 31, 2003. This year's first
quarter revenue improved eight percent to $1.54 million with net income of
$46,031, or $0.01 per share, compared to revenue of $1.43 million with net
income of $2,221, or $0.00 per share, for the quarter ended March 31, 2002.

         Kyle J. Doyel, Kyzen's President and CEO, said that this year's first
    quarter was the Company's third consecutive profitable quarter and its
    fourth profitable quarter in the last five. The Company has accomplished
    this feat by executing its strategic plan of focusing on new product
    introductions and diversification in new niche cleaning opportunities in
    semiconductors, optics and metal finishing while continuing its efforts in
    electronic cleaning. The result of this focus has been increased revenue in
    most product lines.

         "It has taken a lot of hard work," Doyel commented, "to increase our
    sales and profits given the current economic environment. We are guardedly
    optimistic about our ability to continue achieving consistent revenue
    streams and profitability throughout 2003. As we continue to leverage our
    marketing, sales, technical resources and infrastructure, we believe we
    should gain even more traction in our business in the coming quarters.

         "An example of this traction is the recent introduction of the
Company's new electronic cleaning product, Aquanox A 4512. This product recently
received the 2002 Vision Award for innovative products from a leading industry
magazine at Apex 2003, a major trade show in Anaheim, CA. While we already have
a full line of robust electronic cleaning products, our chemists and engineers
continue to advance our leadership position in this industry through new
products and technology to meet the ever-changing and more demanding needs of
our customers," said Doyel.

         At today's Annual Meeting of Shareholders, Mr. Thomas M. Forsythe and
Mr. James R. Gordon were re-elected to serve on the Company's Board of Directors
until the 2006 Annual Meeting. Following the Annual Meeting, the Board of
Directors approved an expansion of the Company's stock repurchase program to
include the repurchase of the Company's common stock through privately
negotiated transactions in addition to open market purchases made at prevailing
market prices.
