TERGITOL™ L-64 Surfactant

Nonionic surfactant that has good wetting ability, a high degree of detergency, and low foam characteristics. It is readily miscible in water and can be used in combination with other surfactants in a wide range of aqueous formulations. It is an exceptional high temperature foam control agent due to its inverse water solubility and low foam characteristics. It is used in such processes as fermentation, food processing, adhesives, paper processing, and metal working products. It is also used as a rinse aid, an emulsifier in latex paints, adhesives, and a component of sanitizing solutions. It provides high thermal and chemical stability with good detergency and rinseability​. It can also be used in oilfield drilling and production formulations.

A defoaming surfactant you can count on

By lowering surface tension, controlling foam and enhancing rinseability of aqueous solutions, TERGITOL™ L-64 nonionic surfactant can help a variety of household and cleaning products perform at the highest level.

Due to its inverse water solubility and low foam characteristics, TERGITOL™ L-64 provides excellent control of high temperature foam. Additionally, its wetting and rinseability properties reduce spotting and filming left behind on hard surfaces.

Broad formulation compatibility

TERGITOL™ L-64 is an ethylene oxide/propylene oxide (EO/PO) copolymer surfactant that is readily biodegradable, not based on alkyl phenol ethoxylate chemistry, CleanGredients® listed and Safer Choice approved. The excellent solvency makes it an appropriate choice for sanitizing solutions and other cleaning applications.
