Santal is a warm, creamy, soft woody scent and the fragrance world's term for a sandalwood-style accord. Its main molecule, santalol, is heavy and slow to evaporate, so santal sits at the base of a blend and stays present long after brighter notes fade. In Sero's Renew it grounds the eucalyptus and juniper. "Santal" usually means a synthetic sandalwood accord, not sandalwood essential oil.
Santal is the warm, creamy, soft-woody scent most people picture when they think "sandalwood." It is smooth rather than sharp, with a faintly milky, almost sweet warmth. In a candle it is the note you notice last and remember longest.
Santal vs. sandalwood: what is the difference?
"Santal" is the fragrance world's word for a sandalwood-style scent. True sandalwood essential oil comes from slow-growing Santalum trees, it is expensive, and wild harvesting has put real pressure on those forests. So most santal you smell, in candles and fine fragrance alike, is a carefully built accord designed to capture sandalwood's character with consistent quality from batch to batch. Ours is synthetic, and for this material we think that is the more responsible choice. (More on the difference in our guide to essential oils vs. fragrance oils.)
Why santal lasts so long in a candle
Santal is a base note. Its signature molecule, santalol, is large and heavy, which means it evaporates slowly. Lighter top notes flash off early in a burn, but santal is still releasing scent at the bottom of the melt pool. That is why perfumers reach for woods like santal as fixatives: they hold a blend together and give it staying power. (Here is how a candle actually turns wax into scent.)
What pairs well with santal
Santal keeps good company on both ends of a blend. Against crisp tops like eucalyptus and juniper it adds warmth and grounding; alongside other woods and resins like cypress and smoked oud it builds depth. In Sero's Renew, santal is the quiet base beneath peppermint, eucalyptus, and juniper, the thing that keeps the blend from feeling thin.

Frequently asked questions
Is santal the same as sandalwood?+
Santal is the fragrance term for a sandalwood-style scent. True sandalwood oil is costly and ecologically strained, so most santal is a synthetic accord built to smell like sandalwood with consistent quality. Ours is synthetic.
What does santal smell like?+
Creamy, soft, and woody, with a warm, slightly milky smoothness. It is rounder and less sharp than cedar or pine.
Is santal a top or base note?+
A base note. Santalol molecules are heavy and evaporate slowly, so santal lasts longest in a burn and anchors the other notes.
Is a santal candle safe for pets?+
Santal in candles is almost always a synthetic accord rather than sandalwood essential oil, so it does not carry the concentrated essential-oil compounds behind most pet warnings. As with any candle, burn it in a ventilated space and keep pets away from the open flame.
What scents pair well with santal?+
Woods and resins like cypress and smoked oud, and fresh tops like eucalyptus and juniper, which is exactly how we use it in Renew.
Why does santal last longer than other notes?+
Because it is a base note. Its large molecules vaporize slowly, so it keeps releasing scent after lighter top notes have burned off.
