I too use BCN's Vanilla Stabilizer and it is the best on the market. I have a vanilla champagne soap that gets a medium-dark caramel color and with VS they are still a lovely white with two tones of blue swirls. Though I had one that I left on the bathroom counter and it's darkening a bit but the others I kept are still perfect and they are a year old that I made for a baby shower. No other stabilizer has worked as well.
