How Much Fragrance Oil to Add to Candle Wax

Let’s be real: a candle without a strong hot and cold throw just isn’t doing its job. Whether you’re aiming for that dreamy unlit scent or the room-filling fragrance when it’s burning, timing and dosage make all the difference.

Stir in at the Right Moment

Fragrance oils bond best with wax at a certain point in the melt.

Soy & CocoSoy: Add between 65–75°C (150–170°F). This keeps those delicate top notes intact.
Paraffin: Can handle slightly higher temps, around 80–85°C (175–185°F).
Beeswax blends: Often need fragrance added at lower temps once the wax cools slightly.

💡 Pro tip: Stir gently but thoroughly for 2 minutes so the fragrance blends evenly through the wax.

The Magic Percentage

The right fragrance load is the secret to unlocking scent throw.

Reddit’s go-to range: The sweet spot is 8–10% by weight (not volume). Push past 10% in soy or coconut wax and you risk separation, sweating, or poor burning.
Paraffin & Specialty Blends: Some can take more 12–15%, but never exceed the wax manufacturer’s maximum load. More fragrance isn’t always better; it can create safety risks and poor performance. Alot of paraffin blends work very well at 6%.
Quality counts: compatibility between fragrance and wax is just as important as quantity. A high-quality, well-matched oil at 8% can outperform an incompatible fragrance at 12%.

Cold vs Hot Throw

Cold Throw (the “hello” scent): Let your candles cure. Soy and coco-soy blends thrive with a 1–2 week cure, while paraffin often needs less.
Hot Throw (the “wow” scent): Comes down to wick size, fragrance quality, and burn conditions. A balanced wick helps release fragrance without overpowering or under-burning.
