Ivanhoe originally installed hot oil esterification reactors to produce emulsifiers and actives for our foam control formulations, but over time, we identified a need in the market for specialty esters which we launched as a complement to our foam control technologies. Ivanhoe manufactures chemistries that have function for oil field applications, including sorbitan, glycerol, and polyol esters with a number of naturally derived or bio-based products.

Glycerol Esters
Glycerol esters are derived from vegetable sources and function as co-emulsifiers that work in conjunction with higher HLB emulsifiers to form stable emulsions upon use. These esters also serve as lubricants and can help solubilize other additives into drilling and fracking fluids.

Sorbitan Esters
Sorbitan esters are low HLB surfactants derived from vegetable sources. Sorbitan esters function as emulsifiers and lubricants for drilling and fracking fluids as well as dispersants for guar slurries.

Polysorbates are high HLB surfactants made via the ethoxylation of sorbitan esters. They can perform as emulsifiers and reduce surface tension for fluids.

PEG, PPG and EO/PO Fatty Acid Esters
Ivanhoe offers a wide range of esters manufactured through the reaction of fatty acids and PEGs, PPGs, and EO/PO block polymers that are used as multifunctional emulsifiers and lubricity additives.
