Description and usage notes:
This is the trans isomer. Strong and persistent balsamic odour, becoming fruitier with increasing dilution. Very useful in amber and oriental styles of fragrance and in combination with labdanum.
Arctander puts it like this “This ester is widely wed in perfume compositions, but normally at very low concentration. It imparts power and sweet-fruity, balsamic ‘Oriental’ notes to Ambre bases, Citrus colognes (where it blends excellently with Labdanum products), Carnation (where it introduces freshness), Narcisse, Lavender, Fruit and Spice blends, etc.”
Usage level is from traces to about 2% of the concentrate.
This material is solid with a melting point around 38 Centigrade, but repeated melting can result in polymerisation of the product (ultimately rendering it useless) so to minimise the need for this it is supplied by default as a 50% solution in DEP.
