Coconut Fractionated consists of “saturated” medium-chain fatty acid triglycerides opposed to “unsaturated” short or long chain fatty acid triglycerides found in all other carrier oils we offer.

The reason why Coconut Fractionated has such a long shelf life is because "unsaturated" fatty acid triglycerides have one or more carbon double bonds in their long fatty ester side chains which are typically 16 to 20+ carbon units long.

The double bonds in these side chains are susceptible to oxidation over time and their reactions with oxygen are what produce the rancid odour that you may have noticed in your carrier oils. Whole coconut oil also has some quite long unsaturated fatty acid triglycerides (which is why it is a solid at room temperature). But the coconut oil is special in that it has a relatively high percentage of shorter length (C8, C10 ), completely saturated (no double bonds) triglycerides. Theses smaller fatty acid triglycerides are separated from the whole coconut oil to give us what is known as "Fractionated Coconut Oil” which remains liquid down to very low temperatures.
