Antifoaming Agent. Any substance that acts to reduce the stability of a foam it may also act to prevent foam formation. Terms such as antifoamer or foam inhibitor are used to specify the prevention of foaming, and terms such as defoamer or foam breaker are used to specify the reduction or elimination of foam stability. Example poly(dimethylsi-loxane)s, (CH3)3SiO[(CH3)2SiO] R, where R represents any of a number of organic functional groups. Antifoamers may act by any of a number of mechanisms.
