(For M&P soap bases only.) Vanilla Color Stabilizer is a product that is added to melt and pour soap bases to help minimize the chance for brown discoloration from vanilla based fragrance oils. Many soap fragrance oils contain Vanillin or Ethyl Vanillin (vanilla extract) in their formulation which can cause products to discolor or become brown over time. Vanilla Color Stabilizer minimizes the chance for discoloration by slowing down the naturally occurring vanilla aging process. Unlike other Vanilla Stabilizers on the market, ours has no harsh odor and is crystal clear. Flashpoint: 200°, Vanilla Content: 0.00%
