I created this tincture on 9/12 and put it in a Case with Fluorescent light. It oxidized in about 4-5 days. Google says that MCT oil is what caused it to turn, what do you guys think?
Well you should really be using amber glass to protect your tinctures contents.
Its definitely oxidizing.
It’s either oxidizing or somehow you got some base in there. Maybe the mint terps you added have a mild base? The CBD phenolate anion is pink/purple. Take some of your tincture and add some acid to rule it out.
Did you smell it ?
