Ivanhoe operates hot oil esterification reactors to manufacture non-ionic surfactants that have a wide range of application. Many of our surfactants have direct and indirect food clearances appropriate for use in water treatment formulations. Our full service laboratory can design esters for your specific application and we have a range of reactor sizes including pilot to meet your supply requirements.

Glycerol Esters
Glycerol esters are derived from vegetable sources and function as co-emulsifiers that work in conjunction with higher HLB emulsifiers to help form stable emulsions upon use. These esters have some anticorrosive properties and can help solubilize other additives into formulations.

I-MUL GMO LM Glycerol Monooleate, 32% monoester Liquid 2.8
I-MUL GMO K Glycerol Monooleate, 42% monoester Liquid 2.8

Sorbitan Esters
Sorbitan esters are low HLB surfactants derived from vegetable sources. Sorbitan esters function as co-emulsifiers and work particularly well with polysorbates to form stable emulsions.

S-I 60K Sorbitan Monostearate Solid 4.7
S-I 20K Sorbitan Monolaurate Liquid 8.6

Polysorbates
Polysorbates are high HLB surfactants made via the ethoxylation of sorbitan esters. They can perform as wetting agents and rinse aids as well as emulsifiers.
