I do mine with a refined shea, then I add some hemp oil, jojoba, and a small amount of sweet almond oil. I use cornstarch and also FO in mine too. I have not had a problem with it staying whipped. I usually melt the shea, add the oils etc them put it in the fridge til it starts to get s skin on top then I take it out and whip the day lights out of it. Mine does make your skin shiney when you first put it on. I don't use a preservative as I want mine to be "natural" but I do have an expiration date on it.
