Why do some fragrances turn brown?
Vanilla based fragrances will always turn color…the more vanilla, the more likely the soap will eventually turn dark brown. The color change can occur from days to weeks to months. It is most often associated with the vanilla level in the fragrance oil. It is an inherent property of the vanilla. We developed a product called Crafter’s Choice Vanilla Color Stabilizer. This product is added to MP Soap and it will stop a vanilla fragrance from turning brown. It does not work in CP or HP Soap.
