AI Technical Summary
Existing perfume ingredients like Ambermax™ exist as complex mixtures of isomers, with some contributing significantly to the desired odour and others causing off-notes or inefficiencies, leading to unsustainable use of resources.
Development of a perfume mixture enriched in specific isomers that contribute to the desired odour character and intensity, while being free or substantially free of isomers that do not, using a precise formulation of compounds according to formulas I and II, and optimizing the preparation process with enantio-enriched iso-longifolanone.
The resulting perfume mixture is more efficient and sustainable, delivering the desired odour with a higher odour per carbon ratio, reducing the presence of undesirable isomers, and requiring less raw material.
