So we're nearing the end of summer here and we've had a pretty humid month. I've noticed on one batch only, that I'm getting a dark dew on top. Very little, pinprick dots on top of my soap, never on the sides. Maybe about a dozen a bar. The soap is fragranced with Sweet Pumpkin Spice by WSP (the fragrance has a max usage of 9.4% and I used at 7%). The recipe is tried and true, superfatted at 5%, and my only additives are kaolin clay, colloidal oatmeal, sodium lactate, and mica. I'm thinking it may be very mild FO separation, even though the fragrance specs and the reviews say there is no separation. I'm wondering however, if it could be glycerin dew because of the weather. Can glycerin dew discolor with the fragrance? I don't see it on my other soaps, so I don't think this is the answer...and I also run a dehumidifier off and on in my soap room. I've licked it and no zap. The issue is so minimal, I'm not worried...just curious as to what could be going on.
