Hello all! I bought 2 meters of polyrethane foam pipe insulation and thought I would try to use it as a circular mold for soap embeds. Someone mentioned it might have chemicals that may leak into the CP soap. What do you all think? It look pretty perfect to me. Slit along the side, easy to tape together and cheap enough to use once if I have to break it to get the soap out. Will not make lots of it, so will not produce masses of garbage.
