A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed.
Typical biochemists study chemical processes and chemical transformations in living organisms, other biochemists study DNA, proteins and cell parts. The word "biochemist" is a portmanteau of "biological chemist."
Biochemists also research how certain chemical reactions happen in cells and tissues and observe and record the effects of products in food additives and medicines.
