                KYZEN CORPORATION REPORTS FIRST QUARTER RESULTS;
                           COMMENTS ON ANNUAL MEETING

                     SEVENTH CONSECUTIVE PROFITABLE QUARTER

NASHVILLE, TN (May 5, 2004) . . . . Kyzen Corporation (OTCBB: KYZN.OB), a
specialty chemical company that is a leading provider of products and processes
for precision cleaning applications in high-technology manufacturing
environments, today announced results for the first quarter ended March 31,
2004.

         Revenues rose slightly to $1.60 million for the quarter ended March 31,
2004 as compared to revenues of $1.54 million during the same quarter in 2003.
Net income increased 28% from $46,031, or $0.01 per diluted share, in the first
quarter of 2003 to $59,067, or $0.01 per diluted share, for the first quarter of
2004.

         Kyle J. Doyel, Kyzen's President and CEO, said, "Consistently improving
our revenues and controlling our costs have allowed Kyzen to achieve its seventh
consecutive quarter of profitability. We continue our sales and product focus on
the Technical Roads of Electronics, Semiconductors, Optics and Metal Finishing
by developing superior products and consistent delivery. We are also continuing
to develop our relationships with suppliers involved in other areas of the
cleaning industry, as well as relationships with companies using other channels
to the same market."

         Doyel continued, "There appears to be more activity in our electronics
marketplace in the last six months. We see it in increased interest with our new
cleaning products, and we are also hearing that capital equipment suppliers are
confirming a similar upward movement in this market for their products."

         For the first quarter ended March 31, 2004, gross profit margins were
55.9% versus gross margins of 56.9% for the first quarter in 2003. The Company
attributes the decline in gross margins to recent increases in the cost of
certain raw materials from suppliers due to increased energy costs.

         On April 27, 2004, the Company held its Annual Meeting of Shareholders
in Brentwood, Tennessee. Directors Jack Davis and Kyle Doyel were re-elected to
serve as directors until the Company's Annual Meeting of Shareholders in 2007.
