Ethoxylates
UNITHOX™ ethoxylates are nonionic emulsifiers and wetting agents with high molecular weights and melt points. These NuCera ethoxylated products are produced from UNILIN™ alcohols, which are fully saturated, long chain, linear, C20 to C50, synthetic alcohols. The relative effects of the hydrophilic and lipophilic portions of UNITHOX ethoxylates vary according to the types and relative amounts used of starting alcohol and ethylene oxide. Thus, UNITHOX ethoxylates can be tailored to provide unique surface-active properties that are useful in a wide range of applications. They can also be readily blended with other surfactants to deliver a truly customized solution.

Product Benefits
The hydrophobic and hydrophilic components of UNITHOX ethoxylates provide functionality to secure many advantages for end users of these products: Typical properties features long hydrophobic chain UNITHOX ethoxylates can be dispersed in both water and a wide range of organic media. They are also excellent dispersion aids. They can disperse a wide range of media in both aqueous and organic systems:
PIGMENTS: Phthalo blue, lithol rubine, zinc oxide, carbon black, iron oxide, titanium dioxide
WAXES: Paraffin, microcrystalline, synthetic (POLYWAX™ polyethylenes)
OILS: Silicone, soybean
RESINS: Epoxy, polyester, rosin ester, terpene phenolic acid, alkyd
UNITHOX ethoxylates provide excellent emulsification properties. The presence of the long hydrophobic chain affords them the ability to emulsify high molecular weight synthetic or natural oil phases in aqueous systems.
Specialty Polymers and Waxes to Meet Your Needs
Falex tests on several UNITHOX ethoxylates indicate they provide excellent anti-wear (ASTM D-2670) and extreme pressure lubricating (ASTM D-3233) properties in water-based lubricant formulations. This, along with their ability to disperse a wide range of components into aqueous systems, makes them excellent building blocks for metalworking and other lubricant formulations.
Applications
There is a wide range of possible applications for UNITHOX ethoxylates. Many of these are based on the product’s ability to act as a dispersant or an emulsifier.
Dispersion aids in water-based coating and ink applications
