defoamers
Agents which inhibit the build up of foam, or
which reduce foam or entrapped air by causing the
bubbles to burst, thus releasing the air. Most
commercial defoamers are mixtures of
surface-active agents, hydro-carbons, alcohols,
polymers, etc., to increase their effectiveness in
multiple applications. Defoamers are used in
papermaking operations. Also called "anti-foam
agents. " (17 )
