I would like to add calendula extract and vitamin e oil to my lotion recipe, which is as follows:

750 g water
50 g coconut oil
50 g rice bran oil
40 g sweet almond oil
20 g shea butter
50 g e-wax
40 g stearic acid
10 g optiphen
20 g cyclomethicone

I'm just not sure exactly how to go about it, as far as the % to use (I know I only want a little, though), and what to cut (coconut oil, rice bran oil? etc).

Thanks!

That depends; is your extract oil or water soluble? At what % are you planning on adding it?

Put a drop on your finger and run it under water. If it disolves cleanly, add it to your water phase. If it beads up, it's oil soluble. I would add it to your oil phase.

If the calendula is the aqueous extract - that's what I use - then try 2.5% in the cool-down phase. (25g/kilo)
Vitamin E (tocopherol) needs to be added to the oils. It isn't water soluble. I'd use about 0.2% (2g/kilo)
