Perfumers wouldn’t be without patchouli for the richness that it gives to fragrances. Patchouli makes its way into many chypre and powdery fragrances, swirling exotically alongside lavender, sandalwood, labdanum and bergamot, clove, clary sage, as well as vetiver. Perfumes and Colognes often use patchouli as a base note because it provides for long-lasting and deep fragrances.
