The breathtaking scent of hyacinths just lets you know winter is over! A little wonder of a fragrance oil, our Hyacinth FO lasts extremely well in CP soap and is another one of our oils that helps to expedite trace in CP soap. This FO is extremely concentrated and we feel safe in saying you could cut the amount needed in your formula and still get an awesome result. Very long lasting and does not fade. Not for internal use.
