Northern Thailand
A selection of our most distinctive materials — some extracted for the first time in perfumery, all traceable from the harvest field to your bench.
Green chemistry,
ancestral patience.
We combine French fragrance heritage with cutting-edge green chemistry to extract delicate aromatic profiles — without compromising the molecule or the land it came from.
Solvent extraction
Low-temperature solvent extraction preserves the delicate volatile profile of fresh flowers and leaves, capturing molecules that steam distillation would destroy.
Advanced technology: Solventless and CO₂
Tincture, Ultrasonic assisted and Supercritical CO₂ extraction for the purest, solvent-free absolutes. Ideal for sensitive materials and brands seeking the cleanest possible label.
Upcycling R&D
We turn byproducts, cocoa husks, makiang pulp or mandarin peels into traceable, zero-waste absolutes. Luxury grade, vegan, with radically reduced environmental impact.
A French laboratory
rooted in Chiang Mai.
Founded in 2022 and based at the Chiang Mai University Science & Technology Park, LOSiam bridges two decades of French expertise in natural extraction with exclusively the extraordinary biodiversity of Northern Thailand.
We source directly from Thai farmers, often within hours of harvest, and work closely with academic partners to introduce species never before extracted for the fragrance industry. Every batch is traced from field to flask, Nagoya-compliant, and IFRA-certified.
