General Uses Top
Suggest a correction!Common products:
- Sawn timber (hardwood) used for furniture, flooring, interior joinery, and high‑quality veneer; leaf essential oil containing roughly 50 % safrole used in fragrance bases and as a flavoring ingredient in food‑grade applications.
Industrial and craft applications:
- The wood is processed into sawn boards for cabinetry, wall paneling, and turnery; it is also suitable for decorative veneer and small craft items such as turned pens and sculptural pieces.
Wood and fiber:
- The species yields hardwood suitable for furniture, flooring, veneer, and small‑scale craft items; the wood has a density of about 0.71 g cm⁻³ at 12 % moisture, a fine even grain, low shrinkage (radial ≈ 4.5 %, tangential ≈ 7.5 %), and moderate strength (MOR ≈ 124 MPa, MOE ≈ 15.5 GPa).
Fragrance and cosmetics:
- Hydrodistillation of fresh leaves yields ≈ 0.3 % (dry weight) oil; the oil is dominated by safrole (≈ 50 %) with eugenol (≈ 3 %) and α‑pinene (≈ 5 %), giving an almond‑like scent used in fine fragrance, soap, detergent, scented candles, and other cosmetic preparations.
Properties relevant to use:
- Wood: density 0.71 g cm⁻³ at 12 % MC; shrinkage radial 4.5 %, tangential 7.5 %; modulus of rupture 124 MPa; modulus of elasticity 15.5 GPa; durability class 2 per AS 5604‑2005.
- Essential oil: safrole‑rich composition provides persistent aroma; the oil’s refractive index ≈ 1.496 at 20 °C, specific gravity ≈ 0.985, and low water solubility make it suitable for incorporation into oil‑based fragrance bases.
Standards and regulation:
- Timber durability classification follows AS 5604‑2005 (Australian Standard for Timber Durability), which places the species in durability class 2 (moderately durable).
- Safrole usage in cosmetics and fragrance complies with IFRA standards, which limit safrole to ≤ 0.01 % in leave‑on products and ≤ 0.05 % in rinse‑off products; timber imports must meet Australian Biosecurity Act requirements for wood pests.
Sustainability and sourcing:
- The species is assessed as Least Concern in the IUCN Red List (2021) and is not listed as threatened in Australian national conservation databases.
- Harvesting occurs under New South Wales forest management plans that set annual quotas, require regeneration of harvested areas, and protect high‑conservation‑value forest patches; small‑scale cultivation for essential‑oil extraction is carried out on certified organic farms, providing a renewable source of both timber and fragrance oil.
