Advice On Dermal Absorption Carrier?

[BrianF]

I'm going to undertake an experiment with pure vitamin powders and I want to deliver them to me personally via the skin. I would like to know your thoughts on two things?

1) What would be the most efficient carrier (DMSO for e.g.) for a B-Vitamin powder?

2) What ratios would be advisable?

Extremely grateful for any feedback?

Thanks
