DeTHOX® L61, aka Poloxamer 181, is a low-foaming, nonionic surfactant used for wetting, emulsification, and defoaming in industrial and cleaning applications. Its strong hydrophobicity and low HLB (~3) make it ideal for stabilizing water-insoluble systems, enhancing wetting on metal and hard surfaces, and controlling foam in metalworking fluids, detergents, and coatings. DeTHOX® L61 also serves as a co-surfactant with higher-HLB emulsifiers to fine-tune emulsion stability and performance across diverse formulations.

Functions: Defoamer, Emulsifier, Surfactant, Surfactant (Nonionic), Wetting Agent
