The orange tree is one of the most amazing suppliers of essential oils, supplying us with unique fragrances from its many parts. In addition to orange oil and petitgrain, we have the flowers, which create one of the most divine scents. When distilled, we call the oil neroli, which also creates orange flower water. When solvent extracted, we call it orange blossom absolute. There is also orange flower CO2 extract, which is more similar to neroli in scent, and probably the truest to nature.
As with many other florals, the different types of orange blossom are expensive, and quality can vary. If you can't afford them, look for a high quality petitgrain or perhaps petitgrain sur fleurs, which includes the flowers in the distillation. If you see orange blossom water absolute, beware, this might not be your oil. It has a very dirty scent, which has it's uses in tiny quantities, but out of the bottle it is rather gross.
Where to use neroli or orange flower absolute? Besides blending it with other florals or citrus oils, you can use it in oriental, chypre, amber and colognes.
