Santalum Album (Sandalwood) Oil

What it is

Sandalwood oil is distilled from the heartwood of Santalum album and is typically 70 to 90% alpha- and beta-santalol. It is one of the oldest and most expensive perfumery materials, which means adulteration with cheaper woods is common. Regulation (EU) 2023/1545 added both the oil and the isolated santalol to the declared-allergen list.

What it does well

• Distinctive creamy woody scent with excellent longevity

  Santalols are low-volatility and hold a fragrance together. Anti-inflammatory effects of sandalwood have been explored in early research but are not established at cosmetic concentrations.

  Strong evidence

Worth knowing

• A recognised, if infrequent, contact allergen

  Sandalwood oil has been reported as a cause of allergic contact dermatitis and was among the additional substances the SCCS identified for individual labelling, which is why it now appears on EU packs.

  Matters most toPeople with a known fragrance or essential-oil allergy.

• Frequently adulterated

  Because genuine Santalum album oil is scarce and costly, material sold under that name is often blended with Australian sandalwood or synthetic santalol substitutes. This affects what you are actually exposed to.

  Matters most toPeople trying to avoid a specific known allergen.
