Sandalwood (sandalwood, sandalwood, santal, E166) is a small tree growing in the deciduous forests of eastern tropical Asia and Ceylon.
Sandalwood wood is used to create expensive furniture and dyes, contains santalin, santalic acid, santal and pterocarpine.
Sandalwood is also an obsolete name for plant pigments obtained from a number of trees, as well as paints based on them. They were named after the sandalwood (Pterocarpus santalinus), which gives a red pigment. Most often, sandalwood meant red paint, not necessarily from sandalwood, but, by analogy with red, there were also blue sandalwood-Campeshevoe tree (Haematoxylum campechianum).
Sandalwood was used in the dyeing of fabrics, in icon painting, etc.
