I've had really good experiences with the one that I buy from Bittercreek North. Granted, I've only ever used it with 2 different FOs so far that only discolor to a medium tan/light brown color (Santa's Pipe from Sweet Cakes and Sugared Spruce from WSP), but my batches that I've made with the stabilizer (which I colored white with TD) have remained a stark white color for
at least a year, which works out great if you know your soap will get used up within a year.
I use an equal amount of the stabilizer as per the weight of my FO, and I add the stabilizer in with my fats/oils (instead of mixing it with the FO first). I mention that, because that was the advice given to me from other soapers who had experience working with it. They said I would get the best results mixing it into the batch that way, and so far, their advice has worked out very well for me. One of these days I need to try it out on one of my FOs that goes really dark brown, and see how it fares.
