The two main types of Benzoin are Siam (styrax tonkinensis) and Sumatra (styrax benzoin). The Sumatran type is much cheaper to produce and coarser than the superior Siam quality. We offer the superior Siam type.
As Benzoin is a resinoid, it comes in solid form. We use an odourless diluent - benzyl benzoate (a natural constituent of benzoin) - to liquefy it so that it is practical to use. Even diluted to 40%, it can still solidify easily and the bottle may be warmed in the hands or in warm water before use.
We source this oil from Siam (the old name for Thailand).
It is Steam distilled from the resin.
