Vanilla Colour Stabiliser: For melt and pour soap only, this product will keep your soap a nice white or ivory colour. Use it with any brown colouring fragrance and you will be thrilled by the results! For best results use at a 1:1 ratio (this means equal parts Vanilla Colour Stabiliser to Fragrance Oil). This additive keeps the soap from browning while allowing the original scent (whatever you're trying to use - Vanilla, Chocolate, Butterscotch etc...) to shine through.
