Tiglic acid and its esters carry a warm, green-herbal character with a fruity-spicy nuance reminiscent of chamomile and unripe apple. In isolation the acid itself is pungent and slightly cheesy-sour, while the esters (methyl, ethyl, geranyl tiglate) smell cleaner, greener and more rummy-fruity. Signature is a natural, hay-like warmth used to boost realism in florals and tropical fruit accords.AI · claude-opus-4-7
