The fragrance is what makes customers buy a candle or soap again. A beautiful candle with a weak scent, or a soap that smells strong on day one and fades by week two, will not get repeat orders. This guide explains how to choose and use fragrance oils for candles and soaps, and what to check when you buy in bulk.
Adding Aromya fragrance oil for candle making.
Why fragrance oils are popular for candles and soaps
Fragrance oils are blended for performance. They are designed to give a strong scent throw (how far the scent travels in a room), to stay stable in hot wax or soap base, and to smell the same batch after batch. They also offer scents that no plant can give directly, such as lychee or watermelon, at a more affordable price than many essential oils.
Fragrance oils for candles
Cold throw and hot throw
Cold throw is how the candle smells unlit. Hot throw is how it smells while burning. A good candle needs both, and the fragrance oil, the wax and the wick all affect this.
How much fragrance oil to add (fragrance load by wax type)
Fragrance load is the weight of fragrance oil as a percentage of the weight of wax. Most candle makers work between 6% and 10%. Each wax holds a different amount:
| Wax type | Good starting point | Typical working range | Usual maximum |
|---|---|---|---|
| Soy wax | 6% | 8% – 10% | 10% (some soy waxes up to 12%) |
| Paraffin wax | 6% | 6% – 10% | 12% |
| Coconut and coconut blends | 6% – 8% | 8% – 12% | 12% |
| Soy–paraffin blends | 6% – 8% | 8% – 10% | 10% – 12% |
| Beeswax | 3% | 3% – 6% | 6% |
Always check two limits: the maximum your wax can hold (on your wax supplier's data sheet) and the maximum safe level for candles on the fragrance oil's IFRA certificate. Use whichever is lower. More fragrance is not always better: going over the limit can cause oil to sweat out of the wax, poor burning, extra soot and safety problems.
Example: for 1 kg of soy wax at 8%, add 80 g of fragrance oil (1,000 g × 0.08).
Tip: start low, make small test candles, and raise the load 1% at a time until you find the best scent throw for your wax, wick and container.
When to add it
Add fragrance oil once the wax has melted and cooled slightly from its highest temperature, then stir gently but thoroughly for a couple of minutes so it binds with the wax. Follow your wax supplier's recommended temperature.
Let it cure
Most candles smell stronger after curing for a few days to two weeks (soy wax often needs the longer end). Test-burn after curing before you judge the scent.
Fragrance oils for soaps
Melt and pour soap
For melt and pour bases, fragrance oil is usually added at a low percentage of the base weight, stirred in just before pouring. Check the soap base supplier's guidance and the IFRA limit for soap.
Cold process soap
Cold process soap is more demanding. Some fragrances can speed up thickening (called "acceleration"), change colour (vanilla notes often turn the soap brown), or fade during curing. Always make a small test batch with a new fragrance before a full production run.
Skin safety
Soap is a skin product, so use only fragrance oils that are suitable for soap, stay within the IFRA limit for that category, and keep your SDS and IFRA documents on file.

Checklist before you buy fragrance oil in bulk
- Test samples in your own wax or soap base.
- Ask for the IFRA certificate and check the candle and soap limits.
- Ask for the SDS for safe handling and shipping.
- Check the flash point on the SDS, which matters for handling and shipping.
- Confirm consistency: can the supplier repeat the same scent every order?
- Start with a sensible quantity. Suppliers with a low minimum (such as 1 kg) let you test new scents without overstocking.

Frequently asked questions
How much fragrance oil do I put in a candle?
Most candle makers use 6% to 10% fragrance oil by weight of wax. Soy wax usually works best at 8–10%, paraffin and coconut waxes can hold up to about 12%, and beeswax only 3–6%. Always stay within your wax's maximum and the IFRA limit for candles.
How much fragrance oil for 1 kg of soy wax?
At 8%, add 80 g of fragrance oil to 1 kg of soy wax. At 10%, add 100 g. Test small batches first.
Can I use the same fragrance oil for candles and soaps?
Often yes, but the safe usage level is different for each. Check the IFRA certificate for both the candle and soap categories.
Why does my candle not smell when burning?
Common causes are too little fragrance, adding it at the wrong temperature, not curing long enough, or the wrong wick size. Test one change at a time.
Does Aromya sell candle fragrance oils in bulk?
Yes. Aromya supplies candle and soap fragrance oils from 1 kg, with IFRA documents on request.
