Oil of the Month-Mimosa

Common name	Cassie Flower/Mimosa
Botanical names	Acacia farnesiana (Cassie Flower); Acacia dealbata, A. baileyana, Acacia decurrens (mimosa). These are 2 absolutes extracted from related trees.
Synonyms	Mimosa-Sydney black wattle
Family	Mimosacae
Extraction	Both cassie and mimosa are extracted via solvents to produce an absolute.  Cassie is also made as a pomade where the flowers are placed in a purified natural fat until it is saturated. This is then melted and filtered and sold as a solid product (mainly in India). A mature plant 10 years old can yield 9 kg of flowers each year. Cassie absolute is employed in preparation of violet bouquets and is extensively used in European perfumery.
Main oil countries	Mimosa is a native to Australia. The concrete and absolute are mainly produced in France and Italy. The pomade is made in India. Approx. 5 tonnes of absolute are produced annually world wide.
Description	Mimosa are a small tree up to 12 metres high with delicate foliage and clusters of fragrant yellow flowers. Various images and growing details can be found here. Mimosa absolute is a golden to amber hard, waxy aromatic substance. Cassie trees are smaller (8 metres). Cassie absolute from concrete is a dark yellow of pale brown, viscous liquid, clear at room temperature but separating waxy crystals at reduced temperatures.
Aroma	Mimosa’s aroma is very rich, floral-woody, slightly green and somewhat resembles Cassie absolute. It has a sweet and more natural odour profile but less spicy than Cassie. Cassie’s aroma is extremely warm, powdery-spicy, at the same time herbaceous and floral with a deep and very tenacious cinnamic-balsamic undertone.
Key constituents %	Mimosa: Hydrocarbons, palmic aldehyde, enanthic acid, anisic acid, acetic acid and phenols Cassie Flower: anisaldehyde, benzoic acid, benzyl alcohol, butyric acid, coumarin, cresol, cuminaidehyde, decyl aldehyde, eicosane, eugenol, farnesol, geraniol, hydroxyacetophenone, methyleugenol, methyl salicylate, nerolidol, palmitic acid, salicylic acid, and terpineol A French mimosa absolute (Acacia dealbata) has been analysed and the followeing volatile components were identifed -hydrocarbons, esters, aldehydes, diethyl acetals, alcohols, and ketones. Most of them are long-chain molecules: (Z)-heptadec-8-ene, heptadecane, nonadecane, and palmitic acid are the most abundant, and constituents such as 2-phenethyl alcohol, methyl anisate, and ethyl palmitate are present in smaller amounts. The heavier constituents were mainly triterpenoids such as lupenone and lupeol, which were identified as two of the main components. (Z)-Heptadec-8-ene (6%), lupenone (20%), and lupeol (7.8%).
Safety	Nil known concerns
Therapeutic uses	Antiseptic and astringent when applied to the skin.
History	Mimosa bark is known as ‘wattle bark’ and is high in natural tannins and was used extensively by the tanning industry. The gum is used in many applications including glues and artwork and pottery. Medicinally used as an astringent gargle and ointment. Also current in British herbal pharmacopoeia for diarrhoea. Dried flowers have been used on wounds.
Blends with	Lavender, Lavandin, floral and spice oils, bergamot, ylang ylang, boronia, frankincense
Aromatherapy details	Mimosa absolute is a hard crystal like product so is difficult to work with in a traditonal aromatherapy way. I weighed and soaked a piece of absolute in alcohol for a period of time and then used this in perfumery. It also just seems to melt with care-I usually try and melt with a hard wax like cocoa butter, rather than a carrier oil. I then have used it in solid products. For the cassie absolute I have only ever purchased this as a diluted product 3% in jojoba. It is quite visocus and very robust. Even at that dilution the aroma is quite strong and overpowering- it seems to hit and go right to the back of the head. Not an unpleasnat sensation-just powerful! It has an instant wake up effect without being astringent or strong (like say a rosemary would wake you up). The effect can be tempered with oils like geranium, spearmint (in minute quantities) or sandalwood. For a very grounding effect try it with Rhuh Kus (Vetivert).In perfumery used give a fresh mown hay effect to blends. Used in at least 80 different perfumes
