Body butter discolouring

[ohsoap]

I made some body butter a couple of months ago, split the batch and scented with 2 FO's. Both coloured with mica, one pink & one gold.
I've noticed that the pink ones (Pink sugar) have discolored and looks like it's separated from the outside (even though it hasn't), it smells fine but I'm pretty sure that it's gone off. I'm wondering if anyone else has ever had this happen? My guess is that the FO was going bad, since it only happened to the half of the batch or does Pink Sugar FO cause all products to discolor over time?

Can't say for sure, but I've not had the best luck with Pink Sugar in emulsified sugar scrub. It seemed to separate out of the emulsion when others looked fine. Also, most Pink Sugars discolor horribly. While you probably won't end up with dark brown body butter (like soap), I would think a tan discoloration isn't far fetched for this FO. I love the fragrance, but hate the color.

If both batches have preservative and the other FO seems fine, I would vote it the FO causing discoloration.
