Now this is somthing I can DEFFENITELY help you guys with. One of My familys companies actually bulk manufactures skincare lotions, pain relief creams containing capsicum, lotions, sun screams. I used to make batches of skincreams on a dail basis. All thats needed is basically a big soup kettle (like the kinds used at cafeterias worldwide). Remember you will always need somthing to mix oil and water efficiently so that you dont get a seperated product. I would also suggest having an Homogenizer so no lumps or seperation can be seen (this must also be done while the product is still hot). Salicylic Acid is used in a lot of acne products, its actually Topical aspirin. Dont forget your carbomer (mixes oil and water) Glycerine. We specialize is making products from Emu Oil (not exactly vegan for you PETA folks). But have many differant formulations availible. IF any of you would like a recipe and instructions to make a hand lotion in which you can add your own THC "Tincture" that can be absorbed by the skin just let me know and I can help you out with this. I no longer work there but did for 8 years and learned everything there is to know about the Skincare product trade (although most of our products are only to be distributed by doctors).
