Yes Liquid Coconut Oil and Fractionated Coconut oil are the same thing but with different names.
So if you're buying liquid coconut oil then you're also buying fractionated coconut oil.
Fractionated Coconut oil is just essentially Liquid Coconut Oil that has had the long chain fatty acids removed from the coconut oil through a process known as hydrolysis and steam distillation which causes the Coconut Oil to turn into liquid at room temperature and helps to extend the shelf life of the coconut oil.
