Caprylic/Capric Triglycerides MCT is a mixed ester composed of caprylic and capric fatty acids attached to a glycerin backbone. Caprylic/Capric triglycerides are sometimes erroneously referred to as fractionated coconut oil, which is similar in composition but typically refers to coconut oil that has had its longer chain triglycerides removed. Chemically speaking, fats and oils are made up mostly of triglycerides whose fatty acids are chains ranging from 6–12 carbon atoms, in this case the ester is comprised of capric (10 carbon atoms) and caprylic (8 carbon atoms).
Caprylic/Capric Triglycerides are a specialized esterification of Coconut Oil using just the Caprylic and Capric Fatty Acids, while Fractionated Coconut Oil is a, standard, distillation of Coconut Oil which results in a combination of all of the fatty acids, pulled through the distillation process. Caprylic/Capric Triglycerides MCT is non-greasy and light weight. It comes in the form of an oily liquid and mainly works as an emollient, dispersing agent and solvent.
