Sandalwood is the name for several fragrant woods. From the Sanskrit candanam the name is borrowed as the Greek sandanon. The local name in Indonesia and Malaysia is "Cendana". Sandalwood essential oil provides perfumes with a striking wood base note. Sandalwood smells not unlike other wood scents, except it has a bright and fresh edge with few natural analogues. When used in smaller proportions in a perfume, it is an excellent fixative to enhance the head space of other fragrances. The oil from sandalwood is widely used in the cosmetic industry and is expensive. The true sandalwood is a protected species, and its demand cannot be met. Many species of plants are traded under the name of "sandalwood". Within the genus santalum alone, there are more than 19 varieties that can be called sandalwood. Traders will often accept oil from closely related species such as various species of santalum genus and the oil of West Indian sandalwood (Amyris balsamifera) from the family of Rutaceae.
