I made a batch of emulsified sugar scrub, cut the batch in 4 to add 4 different scents. One of the batches I used Pink Sugar FO, so I used a vanilla stabilizer with that at 1:1. The pink sugar scent didn't come thru as much as the other 3 scents I used so I remember I used a bit more of that scent. A couple weeks later I'm looking at the jars and there is a bit of oil separating from the Pink Sugar only, none of the other 3 scents are separating. I'm wondering if it was the extra FO I used, or the addition of the vanilla stabilizer. Should I use a bit more emulsifier in the recipe when I make the Pink Sugar or do you not thing that would do anything?
