Extraction Methods of Andiroba

The extraction of andiroba oil is traditionally a labor-intensive, multi-week process deeply rooted in Amazonian culture. Indigenous communities traditionally collect the seeds from forest floors or rivers, where they float after falling from the trees. These seeds are boiled for several hours to soften the hard outer shells and then left to rest or "rot" for approximately two weeks. This fermentation process breaks down the internal tissues, allowing the oil to be manually squeezed out using a primitive wooden screw press known as a "tipiti." This traditional method is highly valued for its sustainability and for preserving the oil's medicinal properties, though the resulting crude oil can sometimes carry a reddish tint from the seed skins.

In modern commercial and industrial settings, the process has been refined to improve efficiency and shelf stability while maintaining the benefits of cold pressing. Modern mechanical cold pressing utilizes industrial screw presses to extract the oil from dried and ground seeds without the use of chemical solvents or high heat, which prevents the degradation of bioactive limonoids like andirobin. Recent technological advancements include the use of pressurized fluids, such as subcritical n-propane or n-butane, and ultrasound-assisted extraction to achieve higher yields and cleaner oil profiles. Furthermore, researchers are integrating cooling systems into mechanical presses to counteract friction-induced heat, ensuring the final product remains a true "cold-pressed" oil with maximum antioxidant capacity.

The most prominent use of Andiroba in fine fragrance is within the Brazilian house Natura’s Ekos collection, specifically **Frescor de Andiroba**. This fragrance, often described as a Floral Aldehyde and launched in 2023, leverages the note's rustic and fresh profile, skillfully combining its characteristic green and woody facets with a gentle floral touch to evoke the mysterious and restorative atmosphere of the Amazonian forest.

• Andiroba is also featured in the niche scent **Connock London Andiroba Eau de Parfum**, where it provides a unique green, fresh, and slightly buttery opening.
• The note is a central ingredient in body care, notably in the Natura Ekos line of products such as **Ekos Andiroba Body Lotion** and **Ekos Andiroba Triple Phase Shower Oil**, highlighting its soothing properties.

A different approach to the note is taken by **Connock London Andiroba Eau de Parfum**. This fragrance builds on the note's fresh, green character by blending it with bright citrus accords of Bergamot, Lemon, and Brazilian Orange in the opening, leading to a floral heart of Iris and Violet. The composition then settles into a deep, earthy foundation featuring Sandalwood, Cedar, and Musk, showcasing Andiroba as a complex green wood that anchors an exotic freshness.

Overall, Andiroba is primarily utilized in contemporary and niche perfumery to introduce a sophisticated, natural, and uniquely Brazilian-Amazonian green-woody element. Its odor profile—described as herbal, bitter, woody, and buttery—allows it to bridge sparkling top notes with warmer, more resinous bases, providing an unusual, non-traditional freshness prized by houses focusing on natural ingredients and ethical sourcing from the Amazonian biodiversity.

The seasonality of the Andiroba tree (Carapa guianensis) is closely tied to the hydrologic cycle of the Amazon rainforest, with peak flowering typically occurring during the mid-rainy season, around March. The subsequent fruiting and annual seed-drop season, which is the primary period for harvesting the oil-rich seeds, generally takes place between March and August, reaching its peak in the early dry season months of June and July. In specific regions like the Amazon Estuary, the most prolific seed production is often observed from March to May during the wettest months, as the species frequently utilizes the tidal system and annual flooding to facilitate the water-based dispersal of its buoyant seeds.
