An unusual material described by Firmenich as a "Floral, herbal, citrus, fruity and green note closely related to part of the geranium character." I would go further: this material is a powerful "Naturalcy enhancer" adding a sharp green edge to all sorts of accords. Mango for example is given fibrous resin qualities with a simple ~1% addition, while a classical fougère can be lent a wonderful green  top/heart note reminiscent of a really good Neroli oil.
 
Finally, as Myrcene and Ocimene are regulated away, Methyl geranate can help take up the slack.
