Opoponax, also known as sweet myrrh, is a resin obtained from the tree species Commiphora wightii, native to East Africa. It is valued in perfumery for its warm, balsamic, and slightly sweet aroma. Opoponax is often used in oriental, woody, and resinous compositions, adding depth, richness, and a comforting sweetness. It is typically featured as a base note, enhancing the complexity and longevity of fragrances.

Opoponax has a rich, warm, and balsamic scent with sweet, honey-like undertones. Its aroma is smooth and resinous, with hints of leather, spice, and a faint earthy quality. The sweet, slightly woody profile of opoponax adds depth and sensuality to fragrances, making it a versatile and grounding note in perfumery.
