Ivanhoe operates stainless steel hot oil reactors that we use to make non-ionic esters which are used as surfactants, emulsifiers, defoaming actives, and adjuvants. While we are not able to manufacture all types of surfactants, we routinely develop esters specific for our customer’s needs.

We have the capability in our R&D lab to manufacture small quantities of esters for sampling purposes and we have a 15 gallon pilot scale reactor with all of the capabilities of our commercial reactors which is often used to scale up a new ester or to provide larger quantities for field trials. Our full-scale reactors manufacture batch sizes ranging from 150 gallons to 3,000 gallons which give us flexibility to manufacture less than truck load and up to bulk truck quantities.

Glycerol Esters
The reaction used to produce glycerol esters yields a mixture of mono and diesters that contain residual levels of glycerin, fatty acids, and water. Ivanhoe has the ability to design our reactions to control the ratio of these reaction products, which can benefit some applications. Open discussions with our customers can provide input to our R&D chemists and allow the development of a customized glycerol ester to match a particular application.


Polyglycerol Esters
The properties of polyglycerol esters can be modified by changing the glycerin polymer length, choice of fatty acid, and degree of esterification. Ivanhoe routinely develops new polyglycerol esters for specific customer applications and would be happy to continue to explore products for new applications.


Sorbitan Esters
While food regulations are very specific to which sorbitan ester varieties are permitted for use, non-food industries could benefit from Ivanhoe’s ability to modify the properties of standard sorbitan esters to better match the needs of a particular application.


PEGs, PPGs, and EO/PO Fatty Acid Esters
Fatty acid esters of polyols offer formulations multiple functions and benefits and can be designed to have a range of properties. Ivanhoe sources many varieties of these polyol raw materials and can react them with several different types of fatty acids to form both mono and diesters. With knowledge of our customer’s application, we can provide formulators with a selection of these esters to determine which type offer the maximum benefit to the formulation.
