Three reactions are commonly utilized in the manufacture of our excipients:
- esterification, a reaction between acid and alcohol leading to ester and water
- interesterification, a reaction between esters to produce new esters
- transesterification, a reaction between ester and alcohol to produce a different ester and alcohol
Depending on the raw materials used, these reactions enable the manufacture of solid, semisolid, or liquid excipients. The fatty-acid chain length and composition in terms of fatty alcohols and mono-, tri-, and diglycerides impact end-product physicochemical—hence functional—properties. Our oleochemists are thus able to develop pharmaceutical, nutraceutical, and cosmetic ingredients having targeted properties through the selection of raw materials and the design of synthesis reactions.
