Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If nonionic surface-active defoamers
Defoamers with >10% ethoxylates classify as organic surface-active agents.
If prepared additives for rubber/plastics
Anti-foaming for polymer processing moves to prepared rubber additives.
If pesticide residue-containing
Disinfectant defoamers with pesticide actives go to Chapter 38 pesticides.
