Fragrance Oils & Essential Oils
Be very careful of fragrance!
Too much scent can cause your candle gel to catch on fire.
The fragrance can be one of the most appealing features of your candle. First the person will look, and then will sniff. But beware, for the fragrance is the most likely culprit for ruining your beautiful candle. Penreco recommends using non-polar fragrance.
Sometimes a candle with newly poured gel will be crystal clear, only to cloud as it cools. The culprit is most likely the fragrance oil’s raw ingredient. Also, you may have added too much scent.
While there are only three grades of candle gel (LP, MP, HP), there are thousands of fragrances. You must specify to your Supplier that you are purchasing the fragrance for gel candles. The fragrance must be of oil and cannot contain water, alcohol, glycerin or any flammable ingredients.
Do not use perfume to scent the gel.
It is important to note that the fragrance has been the major reason for candle problems. Be sure to test your fragrances in some test candles.
Test burn several times. You may then want to let the test candle rest on a shelf for a while and burn it again at another time.
Fragrance that is migrating to the surface can cause an uneven burning. Ask your Supplier for assistance.
Testing The Fragrance Oil
If you currently making wax candles, your fragrances will often work with the gel. However, be sure to use the mineral oil test. To test the fragrance oil, add a little of the scent to a small amount of mineral oil. If it stays clear in the mineral oil, it should stay clear in the cooled candle.
Measuring Fragrance Oil
A little fragrance oil goes a long way with gel candle making. This is especially true of the stronger Grade A scents. The average dosage is up to .5 oz per pound of gel, but this depends on the grade of gel and the
strength of the fragrance.
Warning: Too much fragrance can cause a candle fire.
Add no more than 5% fragrance to your gel, with ranges of 1-3% being the best. One tablespoon per pound of weight seems to be a good ratio, however, the stronger grade the fragrance oil the less you need to add.
You should experiment.
Important! Use caution when adding fragrance to your gel. Be sure that the gel is melted, colored (if any) and ready to pour, before adding your scent. Mix well so as to not create fragrance pools.
Be very careful working with the fragrance around flames. It is flammable. Do not overheat.
It usually takes more scent to cloud the higher polymer gel.
If you are making a wickless gel room freshener, you can load higher amounts of fragrance into the gel.
Speak with your Supplier for more information.
Essential Oils
You can use essential oils in the gel candles; however, the scent will usually burn off quite quickly. While it is preferable to use fragrance oils (stability, price), some customers prefer essential oils. Follow the guidelines in the chapter on Fragrance Oils and be sure to test!
Remember... The fragrance can be one
of the most appealing features of your candle,
but it is also the most likely culprit!
