From Soil to Scent: Indesso’s Responsible Patchouli Journey

At Indesso, patchouli sourcing is guided by three pillars: traceability, environmental stewardship, and social empowerment. Together, these ensure that every drop delivers not only olfactory richness, but also integrity.

'Perfumery has a transformative power that goes beyond evoking emotions,' said Magdalena Rey, technical perfumer at Eurofragance and leader of the project. 'This project clearly demonstrates that a fragrance can be much more than a scent: it can provide relief, confidence and well-being.'

Using an advanced all-optical imaging and optogenetics platform in awake mice, researchers found that the olfactory bulb rapidly filters incoming odor information within the first 30–40 milliseconds of a sniff, preserving odor identity while suppressing later, more concentration-dependent signals.

New Mouse Study Reveals the Brain’s 'Temporal Filter' for Odor Identity and Why Concentration May Matter Less Than Timing

Odor perception may be governed less by static receptor maps and more by dynamic temporal coding across neural networks.

The work identified molecular weight, size, shape and polarity as the dominant drivers separating weak from powerful odorants—findings that align with long-established mass-transport principles governing volatility, sorption and receptor access.

AI Takes on Odor Strength: New Study Maps the Molecular Drivers of Fragrance Impact

Odor strength reportedly proved consistently predictable across a range of state-of-the-art models.

Founded by engineer Laura Sisson (at left) artist-perfumer Sean Raspet (at right), Patina is building a machine-learning–driven platform called Sense1 that models how molecules interact with human olfactory receptors.

Advanced Biotech's extensive portfolio, comprising of natural, synthetic, and fermentation-derived molecules, is constantly evolving to meet the changing demands of our valued clients.

Patients on GLP-1 drugs sometimes describe stronger or more noticeable smells, particularly a reduced tolerance for heavy or fried food odors, alongside occasional increased awareness of perfumes and ambient scents.

GLP-1 Drugs Are Reshaping Scent Preferences and Perceptions

Accounts point to a spectrum of olfactory changes rather than a single predictable effect as reward signalling is subtly rearranged.

Researchers developed a topical cream based on Pogostemon cablin (patchouli) essential oil and evaluated it against Aedes aegypti, the mosquito responsible for dengue, Zika and yellow fever transmission.

New Study Shows Patchouli's 3-Hour Mosquito Protection Potential

molecular docking showed key oil constituents binding to mosquito odorant-binding proteins.

Reaching adverse-effect levels for common fragrance materials would require exposures such as eating approximately 166,000 almonds or more than 300,000 raspberries per day or applying tens of thousands of perfume sprays daily.

Dose, Exposure, and Daily Life: Putting Fragrance Toxicology in Context

How should toxicological findings be interpreted in the context of human health and real-life fragrance use?

A central concern is the estimated cost of more than £500 million associated with generating and submitting U.K.-specific data packages for substances already registered under EU REACH.

The identification of a spatially organized receptor system—rather than a purely combinatorial or random one—could inform future strategies in aroma design, receptor targeting and predictive modeling of olfactory perception.

Spatial Mapping of Olfactory Receptors Reveals New Blueprint for Odor Perception

Contrary to the traditional “zonal randomness” model, each receptor occupies a distinct spatial domain, forming a continuous and stereotyped sensory map.
