YL Valor Question

After I posted the formula for Valor, a follower of this page recently stated that they were a user of the blend and never realized that most of the blend consisted of a carrier oil. They wanted to know how they could determine that since it wasn’t stated explicitly on the website. So I thought I’d explain this to let others know how to recognize when companies aren’t so forthcoming about letting users know when blends are cut with carrier. If you look at the INGREDIENTS section of the Valor webpage you’ll notice the first ingredient is “Capric/caprylic triglyceride.” This is chemical name for MCT oil (Medium Chain Triglycerides) also known as Fractionated Coconut Oil (FCO). This is typical carrier oil used in blends, usually at 75-80%. Hope this helps.
