Direction Grasse pour le SIMPPAR — la capitale mondiale du parfum.

LOSiam – Laboratoire Olfactif du Siam is bringing its absolutes, born from the local biodiversity of Thailand. Flowers, resins, and essences grown and harvested here, at the heart of our land.
Nous apportons nos absolues, nées de la biodiversité locale de Thaïlande. Des fleurs, des résines, des essences cultivées et récoltées ici, au cœur de notre territoire.

What if Thailand were soon to join La Route des Parfums? 🗺️✨
Et si, bientôt, la Thaïlande rejoignait La Route des Parfums ?

The story of perfumery is still being written — and we have our place on that map.
Le monde du parfum est en train de s'écrire — et nous avons notre place sur cette carte.

Makiang. Syzygium nervosum. Northern Thailand.

That intense fuchsia color you see? That's the pulp of Makiang berries, one of Northern Thailand's most antioxidant-rich wild fruits, loaded with anthocyanins and vibrant phenolic compounds.

But here's what makes our Makiang Absolute different: we don't use primary fruit. We upcycle the pulp waste from local production, transforming what would otherwise be discarded into a high-grade fragrance material. Zero waste. Full traceability.

Tart berry. Wild red fruit. A subtle floral warmth with a faintly earthy, jammy depth.

Vibrant. Unexpected. Unmistakably Thai.

From pulp to absolute. Every gram extracted tells a story of sustainable luxury.

🌿 Chalood. Alyxia reinwardtii.

A fragrant bark deeply rooted in Thai culture. Used for centuries in incense, herbal remedies and household rituals to bring calm and harmony. Now, in a bottle for your next fragrance.

What you see in these photos is the full journey. The raw bark, hand-cut and ground. Then the extract, creamy and silky, slowly stirring in the tank after extraction.

Toasted woods. Almond powder. Dried bark. A spicy whisper. A mellow musk that lingers.

Warm, intimate, meditative. The kind of base note that anchors a fragrance and makes it unforgettable.

Ethically sourced. Sustainably extracted. IFRA compliant. Fully traceable. 🌿

🔥 Mountain smoke. Highland hands. Pure Litsea cubeba.

Deep in the hills of Northern Thailand, our farmers dry Litsea berries the way it has always been done. Over open fire. Slowly. With patience.

That smoke you see in the photos? That's the beginning of something extraordinary.

Once dried to perfection, these tiny dark berries head to our lab where CO2 supercritical extraction captures every volatile molecule at its most pristine. No heat degradation. No compromise.

Lemon zest. Fresh ginger. Bright citrus aldehyde. Clean and radiant with a whisper of floral warmth underneath.

One of the most versatile citrus materials in natural perfumery, and ours comes with a story that starts in a mountain barn, with a flame, and two hands that know exactly what they're doing.

Wild-sourced. Traditionally dried. CO2 extracted. IFRA compliant. Fully traceable. 🌿

🌿 Fresh Jungle Pepper.

Wild-harvested by hand from the misty highlands of Northern Thailand. One bunch at a time,picked at peak freshness before heading straight to our lab in Chiang Mai.

This is not your average pepper.

Mandarin zest. Clementine brightness. A piney, ozonic whisper that evokes rain on jungle leaves at dawn. And underneath it all, a gentle electric tingle that lingers, subtle, alive, unlike anything a synthetic can replicate.

45% more citrus-forward than Sichuan pepper. Lighter. Greener. More approachable. A perfumer's secret weapon for fresh colognes, tropical accords and anything that needs that untamed lift.

Wild-harvested. Low-temperature extracted. IFRA compliant. Fully traceable from forest to formula.

A rare ingredient that only exists because a season allows it.
