CBD changes color over time

Not sure if this is the right category. I am using CBD isolate for vapes and tincture.
After a while the oil turns a light yellow and the tincture turns a light pink. Anyone know what that is? Is it normal/expected?

pink color in the tincture is due to the polyphenols present in MCT oil. Over time they will oxidize and change color. Your best bet to prevent this is to add an anti-oxidant. PM me and I can get you some leads.


I would like to keep it as clean as possible but I’m definitely open to learn what if there is something that can help without adding too much shit to it.

Curious about what antioxidants you’d recommend?

Put oxygen absorbers in the packaging.

Doesn’t work as well as one would like, too much already in the solutions
