Styrax gum resin aka benzoin

Styrax benzoin, Styrax tonkinensis, Styrax paralleloneurum

Common Names: Benzoin, Gum Benjamin, Styrax Resin

Description:
Benzoin is a balsamic resin obtained by tapping the bark of trees in the Styrax genus, primarily S. benzoin (Sumatra) and S. tonkinensis (Siam). The raw resin exudes from the tree and hardens into reddish-brown tears, which are collected and used for both perfumery and medicinal purposes.

Aroma Profile:
Warm, sweet, vanillic, and ambery with hints of cinnamon, honey, and caramel. It possesses a comforting, round aroma and serves as a fixative in natural perfumery. The Siam variety is generally softer, sweeter, and creamier, while the Sumatra type is slightly smokier and more intense.

Uses in Perfumery:
Widely used as a fixative and base note, Benzoin is prized in oriental, amber, and gourmand compositions. It softens sharp edges, rounds out florals, and anchors fleeting top notes. In natural perfumery, it’s often tinctured or used in resinous bases and incense.

Regions:
Thailand, Laos, Vietnam (Siam benzoin); Indonesia (Sumatra benzoin)

Extraction Method:
The resin is harvested directly from tree bark incisions and may be tinctured in ethanol or solvent-extracted for perfumery.

Goes Well With:
Labdanum, vanilla, tonka bean, patchouli, sandalwood, rose, myrrh, opoponax

Unique Characteristics:
Its warmth and sweet depth make Benzoin a classic anchor in perfumery, especially beloved in sacred blends, incense, and emotional compositions. It is also used in natural skin care as a healing and preservative agent due to its antiseptic properties.

Tagetes (Tagetes Oil / Marigold)

Tagetes patula, Tagetes minuta, Tagetes erecta

Description:
Tagetes oil is steam distilled from the flowering tops of several species in the Tagetes genus, most notably T. minuta (Southern Cone Marigold), T. patula (French Marigold), and T. erecta (African or Aztec Marigold). Native to Central and South America and widely cultivated in Africa and India, Tagetes plants are known for their vibrant yellow-orange flowers and their strong, herbaceous aroma.

Aroma Profile:
Powerfully green, sharp, and herbaceous, with fruity-apricot-like top notes and a pungent undertone reminiscent of bitter herbs and tarragon. Some species exhibit a camphoraceous or slightly rubbery nuance. The drydown may reveal a balsamic, hay-like character.

Uses in Perfumery:
Primarily used in chypre, herbal, fougère, and rustic floral accords for its assertive top note. In small amounts, Tagetes can impart a fresh, wild character and is occasionally used to round off green or citrus notes. It also finds limited use in flavouring (notably in tobacco) and traditional healing practices.

Regions:
India, South Africa, Argentina, Kenya

Extraction Method:
Steam distillation of flowering tops

Goes Well With:
Citrus oils (especially orange, lemon), galbanum, lavender, clary sage, artemisia, and vetiver

Title: Tuberose

Tuberose (Polianthes tuberosa) is a highly fragrant perennial plant native to Mexico, and it has been cherished for centuries for its captivating, creamy white blooms that emit an intense, rich floral aroma. In the realm of natural perfumery, tuberose is considered one of the most luxurious and sensual floral notes, often used in high-end and artisanal fragrances.

Characteristics and Extraction

The scent of tuberose is complex and multi-faceted, featuring notes of creaminess, sweetness, and an almost narcotic intensity that is both heady and seductive. This makes it a powerful addition to perfumes, where it often serves as the heart or middle note, providing depth and opulence to a fragrance composition.

Tuberose is typically extracted in two primary forms used in natural perfumery:

  1. Tuberose Absolute: This is obtained through solvent extraction, resulting in a thick, deep-colored liquid that retains the full spectrum of the flower's aroma. Tuberose absolute is highly concentrated and potent, often used in minute quantities due to its strength.

  2. Tuberose Concrete: This solid, waxy substance is also produced via solvent extraction and then refined. Tuberose concrete is admired for its golden color and solid form, which can be further processed to produce the absolute.

Perfumery Uses

Tuberose is a versatile note in perfumery, complementing and enhancing a wide range of other fragrance components. It pairs beautifully with:

  • Other White Florals: Such as jasmine, orange blossom, and gardenia, creating lush, romantic bouquets.

  • Spicy Notes: Like clove and cinnamon, which can temper its sweetness and add warmth.

  • Woody and Balsamic Bases: Such as sandalwood, amber, and vanilla, which provide a rich, enduring foundation for the tuberose's voluptuous aroma.

Example Uses in Fragrance Types:

  • Oriental Perfumes: Tuberose adds a rich floral heart to oriental blends, complementing spices and resins.

  • Floral Bouquets: As a dominant or co-dominant note, tuberose enhances the overall floral experience.

  • Chypre and Green Scents: It adds an opulent floral dimension to the fresh, mossy, and woody components.

Additional Notes

  • Historical Significance: Tuberose has been used in traditional garlands and ceremonial offerings, symbolizing both love and danger due to its intense fragrance.

  • Modern Popularity: It remains a staple in luxury perfumery and niche fragrances, appreciated for its ability to evoke both vintage glamour and modern sophistication.
