Fractionated coconut oil (caprylic/capric triglyceride) is a portion of coconut oil that has almost all the long chain triglycerides removed, leaving mainly the medium chain triglycerides and making it a more saturated oil. This saturation gives it a long shelf life and makes it more stable. Fractionating the oil raises the comparative concentration of capric acid and caprylic acid, giving it greater antioxidant properties.
The EWG score is a hazard score ranging from 1-2 (low hazard), 3-6 (moderate hazard) and 7-10 (high hazard) published by the Environmental Working Group. Their data is sourced from the Skin Deep® database and studies published in open scientific literature.
