I have just used up my last Satsuma Guava that I purchased from a Co-op a couple of years ago. I need a new citrus to replace it and it needs to be a fragrance that sticks well enough that the soap will be good to sell in 6 months and use in 1 year. My preference is a blend rather than a single note citrus. I do sell blood orange and patchouli so am looking in the bright rather than earthy types. I am thinking about going back to orange 5x or 10x but I hate to always be limited to orange discoloration. So, do you have a favorite that you think of as really long lasting?
