I have received samples of two vanilla fragrances to try, and to pick holes in. I have had it suggested that I use the fragrances at 2% of the weight of oils. Huh!! Not happening!! If I want a fragrance to work for my customers it has to withstand discounting and fragrance overload as a minimum. What is the point of it working at 2% if the standard usage is 3% with some people preferring to take it higher? I just nod my head sagely, and agree. It has to work in soap, and I will test it as I see fit. We will see what comes of it all.
