About the PlantMimosa is the common name of the flowers from the tree, Acacia decurrens Willd. var. Dealbata in the Fabaceae family and is native to Australia and imported to the South of France where trees are cultivated primarily for processing flower heads into fine perfumery and cosmetic ingredients. Mimosa has been imported to the U.S. and grows in Oregon and California, known commonly as Silver Wattle. In Australia, the tree was known as Sydney Black Wattle. The tree grows to a height of 5-6 meters, however in cultivation they are maintained at about 4 meters through bi-annual pruning.
The tree flowers from mid-December to the beginning of April. In France, maximum production of the concrete is in February-March. Harvest of the flowers takes place in the morning after the dew has evaporated.
Production: With regard to the quality of Mimosa concrete carried by Samara Botane, the flowers only are processed into floral concrete by solvent extraction (petroleum ether/hexane), with a rendering of about 1%. You will find other concretes available of lesser quality made from the flowers/twigs, priced lower. The absolute is obtained by extraction of the concrete using ethanol with a rendering of 25%.
Mimosa concrete has a pale yellow solid appearance. The absolute is a pale yellow-brown sticky semi-solid similar in consistency to honey. Both are soluble in alcohol and propylene glycol.
Although Mimosa concrete is relatively expensive, this is to be expected. It requires 180 to 200 kilos of flowers to yield just one kilo of concrete, which, in turn, gives only 180 to 200 ml of absolute.
Perfumery Uses: In perfumery, Mimosa concrete can brighten a flat or nondescript odor and does wonders for muguet, lilac, new mown hay and similar floral and herbaceous-coumarinic types. The absolute is used in commercial perfumery to round off ‘rough notes’ from harsher materials. It is also used in high-class Hay, Violet, Muguet and Amber colognes. Mimosa has a lovely radiance and should work well in fruity as well as most floral blends.
When working with mimosa concrete, it is best to warm your alcohol and the concrete before attempting to dilute. You will end up with a nice workable cream-like consistency much more conducive as an additive to other natural fragrance ingredients.
