Candles
There is no single fragrance percentage that suits every candle. The correct level depends on the wax, fragrance, wick, vessel and the wax manufacturer's recommended load. Many candle systems are tested somewhere in the mid single digits through to around ten percent, but more oil does not automatically mean more scent. Start within the wax supplier's range, make controlled test candles and choose the lowest load that gives the performance you want.
Candles
Choose a soy wax fragrance by testing it in the exact wax, wick and vessel you plan to sell. Look for good cold and hot throw, clean incorporation, acceptable colour and stable burning. Do not rely only on how the fragrance smells from the bottle. Soy can mute or change some materials, so a fragrance that performs brilliantly in another wax may need a different load or wick setup in soy.
Candles
Weak hot throw is usually caused by the overall candle system rather than one single fault. Common causes include the wrong wick, poor melt pool development, too much or too little fragrance, unsuitable wax compatibility, adding fragrance at the wrong temperature or not allowing enough cure time. Test one variable at a time. Adding more fragrance without fixing the underlying issue can make the candle burn worse and still not improve the throw.

Weak scent throw? Don’t blame your candle wax just yet.
How wax, fragrance, wick and testing work together when assessing candle scent throw.
Treat the candle as a complete system. Test fragrance in the finished candle, control wick, load and cure conditions, compare cold and hot throw, and change one variable at a time.

Weak cold throw can come from a low fragrance load, poor fragrance compatibility with the wax, insufficient cure time, storage conditions or simply a fragrance profile that is less volatile when cold. Before increasing the load, compare the fragrance in a known wax system and check the cure period. Some fragrances are naturally more impressive when burning than they are from the unlit candle.

Yes. The same fragrance can perform very differently in soy, paraffin, coconut and blended waxes. Each wax holds and releases fragrance differently, and the wick and melt pool will also change. A fragrance that gives excellent hot throw in paraffin may feel softer in soy, while another may perform beautifully in a coconut blend. Every fragrance and wax combination should be tested as its own system.
Candles
Test a new fragrance in a small controlled batch using the exact wax, wick, vessel and fragrance load you intend to sell. Record pour temperature, fragrance addition temperature, cure time and wick size. Then assess appearance, cold throw, hot throw, burn behaviour and any sweating or discolouration. Do not launch from one successful candle. Repeat the test so you know the result is reproducible.
Candles
A candle fragrance can change during curing because the fragrance is distributing through the wax and the overall wax structure is settling. Some notes become softer, stronger or more balanced after several days. This is normal, especially with soy and other vegetable waxes. Judge the candle after the cure period you actually plan to use in production, not immediately after pouring.
Candles
Better scent throw usually comes from improving the whole candle system, not simply adding more oil. Check wick size, melt pool, wax choice, fragrance compatibility, mixing, pour conditions and cure time. A slightly lower fragrance load with the correct wick can outperform a heavily loaded candle with poor combustion. Structured testing is usually cheaper and more reliable than increasing fragrance blindly.
