Bryan: I always thought polysorbate 80 that contained biotin and niacin released histamine. Polysorbate on its own....hmmm.... I never knew that.
CCS: Polysorbate 80 is a commonly used emuslifier in cosmetics. It is very good at mixing oils, alcohol and water together.
If you buy it from Puritan's Pride and Swanson's vitamins it contains biotin and niacin. Vitamin Shop also... I think.
You could probably use nicotinic acid as your form of niacin. I use it in most of my homemade concoctions. I use it mainly for vasodilation and hopefully more penetration of other stuff?
You could probably use folic acid also but don't know for sure, just a guess.
Finally, Dr. Proctor says we shouldn't expect much from histamine releasers.
You could probably do better with incorporating nicotinic acid n-oxide as a regrowth agent and penetration enhancer but you'd be violating Dr. Proctor's patent and it's hard to get from what I've read.
