Odour description (decreasing): Balsamic, Sweet, Vanilla, Warm, Spicy, Cinnamon-Like
About this material
Benzoin Resinoid is an aromatic resin derived from the bark of the Styrax tonkinensis tree, primarily found in Laos, Cambodia, Thailand, and Vietnam, with “Siam” historically referring to Thailand.
This variety sourced from Laos via Robertet is distinct from the Sumatra type, which comes from a different species (Styrax benzoin).
It is a thick, sticky, brownish resin; sometimes semi-solid or paste-like depending on extraction method and dilution. It is however typically solvent-extracted to produce a resinoid (as opposed to steam distillation, which would yield an essential oil).
Benzoin Siam Laos is a truly beautiful material that has a persistent balsamic, sweet, vanilla, spicy and cinnamon-like odour. This is far more refined and luxurious than our Benzoin Resinoid Siam EO Thailand
It is much richer and softer than Benzoin Sumatra, often described as more refined and less smoky.
In perfumery, it acts as a fixative and base note; often used in oriental, gourmand, and amber accords. In Aromatherapy it is calming and grounding, with stress-relief and mood-lifting properties.
Comparison to Benzoin Sumatra:
Siam Benzoin: Sweeter, more vanillic, smoother.
Sumatra Benzoin: Harsher, more cinnamic, and smokier.

Creative ideas to explore
Creative directions, not tested formulas.
Resin and air
With bergamot and a dry wood outlineExplore a resinous sketch with a bright opening and a deliberately spare base. Compare a citrus-led version with the resin reference, deciding whether the contrast opens up the idea or competes with the character you want to feature.
Petals and balsam
With rose and soft floral notesSet the resinous material around a familiar rose accord. Compare the flower alone with the resin variation and follow the developing balance, looking for the relationship between petal character and the material’s own listed texture.
A warm amber sketch
With vanilla and smooth wood directionsTry vanilla and soft wood as two separate settings for the resinous character. Compare their effect on the imagined amber structure before combining them, keeping sweetness a deliberate choice rather than an automatic part of every resin idea.

Please read our Documentation Supply Policy alongside the product specification and available documentation.
Synonyms, alternative names, CAS/EC references, botanical names, manufacturer references and external links may describe a substance or material family generally. They should not, on their own, be taken as confirmation of the supplied material’s producer, geographical origin, manufacturing process, grade, purity, constituent levels or batch characteristics.
