craftgrrl | question on body/cosmetic bases

Just a question for people that make body products, since my area of experties is mostly in jewelry. :)

I'm about to go to work in a salon next month and I'm interested in using handmade facial products (cleansers, moisturizers, masks, scrubs, body lotions, massage oils, things like that)...and I want to try and make them myself. I've read a few books about it, but some of the recipes I've seen require a lotion base or cream base or some form of butter or beeswax. That's not the problem. The problem is, for some reason, I'm having a hard time finding the bases. I've found beeswax and mineral mask bases on a site called From Nature with Love but they don't have a lot of lotion or cream bases.

Do you guys buy your bases (and where from) or do you make them from scratch? Links and/or recipes would be greatly appreciated!
