I make just basic soaps using melt and pour, adding in fragrance, and soap liquid colouring.
For some reason, a lot of the soaps form what looks like little bubbles of consensation, anywhere between the day after they are made up to a week later. It does not happen with the ones I don't colour (but still add fragrance to). The little bubbles stay, and they appear to be a darker colour than the soap.
Any ideas? Thanks!
