After my butters and oils have whipped up, I add the dri flo and work that in, then I add the IPM and that's when it gets light and fluffy. The last batch I made I added an extra .5oz of EVOO and it didn't firm up as much, it's much lighter and fluffier. I do the last part on about 8 on the KA, FYI Edit... You can add stuff to it. I usually add the FO the very last. If I want to make several scents I put some butter in a baggie and add the FO and smoosh to incorporate. Then jar it up. It does let some of the air out but thats alright with me. The harder the butter the less people will put on their finger. The less they put on their finger the less greasy they think it is.
