Sandalwood oil is obtained by steam distillation of the heartwood of sandalwood trees, formerly mainly from the East Indian species Santalum album L. (Santalaceae). It is a slightly viscous, almost colorless to yellow liquid with a characteristic, sweet, woody, long-lasting odor. d2020 0.968–0.983; n20D 1.5030–1.5090; α20D 21 ° to 12 °; solubility: 1 vol ≤ 5 vol of 70% ethanol at 20 °C; ester number: max. 10; free alcohol content (calculated as santalol): min. 90%. Santalum sandalwood oil consists almost exclusively of closely related sesquiterpenoids; by far, the main constituents are the alcohols α-santalol, 41–55%, and β-santalol, 16–24%. Mainly responsible for the odor is β-santalol. The trees cultivated for oil production must be at least 30 years old to make oil production profitable. The oil yield, calculated on the amount of wood used for steam distillation, is 4–6.5%.The oil was formerly produced in India and Indonesia in annual quantities of some 100t. In the past decades, the natural resources in India are on the decline and the production in Indonesia has decreased significantly. Alternatively, Australian sandalwood oil has been introduced on the market. This oil type is obtained from Santalum spicatum (R.Br.) A. DC. It also contains santalols as main constituents but differs somewhat in the remaining composition. Australian sandalwood oil is a colorless to slightly yellow viscous liquid, d2020 0.945–0.980; n20D 1.500–1.517; α20 D 16 ° to +4 °; solubility: 1 vol≤5 vol of 70% ethanol at 20 °C. α-santalol 15–25%; α-santalol 5–20%.

용도sandalwood oil (Santalum album)(santal; santalum) is credited with astringent, anti-inflammatory, anti-bacterial, tonic, stimulant, cooling, and soothing properties. It is also considered a good anti-septic in cases of acne and an astringent for oily skin. There are indications that sandalwood oil may promote epidermal cell turnover as some report it stimulates fibroblast growth. Sandalwood could help prevent the skin dryness associated with seborrheic dermatitis, psoriasis, and eczema. In addition, some manufacturers utilize it as a natural colorant to give products a light red or rose tone. Sandalwood oil might produce a rash in hypersensitive people, especially if it is present in high concentrations. It is produced by distillation of the inner wood.
