A woody-amber base material with a distinctive dry citrus-woody character. Opens with a subtle lemony-terpenic facet inherited from the citral moiety, developing into a warm, slightly balsamic woody backdrop reminiscent of cedar and soft amber. Acts as a fixative that lends radiance and warmth to citrus and woody accords.AI · claude-opus-4-7
