ColouringDescription
Not a recognized food additive
Notes
## E166 - Sandalwood **E166** referring to **sandalwood** is **not a recognized or currently authorized food additive** under standard international food additive numbering systems. Sandalwood typically refers to aromatic wood from trees in the genus *Santalum*, which is primarily known for its use in perfumes, cosmetics, and traditional medicine rather than as a food additive. The **essential oils** and extracts from sandalwood are obtained through **steam distillation** or **solvent extraction** of the heartwood. While sandalwood extracts and oils have been used historically in some traditional food preparations and beverages in certain cultures, they are not commonly found in modern commercial food production. The aromatic compounds in sandalwood, primarily **santalol**, are more typically used in fragrance and cosmetic applications rather than as food additives. Since this is not an authorized food additive number, consumers should be cautious if they encounter "E166" on food labels, as this may indicate mislabeling or non-standard usage. **Sandalwood derivatives** would generally be considered **natural** and suitable for most dietary preferences including **vegetarian** and **vegan** diets, but their use in food would need to comply with local regulations regarding novel ingredients and flavoring substances.
