Scented candles are a great way to make your house smell nice and for aromatherapy. A good scented candle can change your mood, and help you get ready for bed. They can also have a physical impact on us even having an impact on our blood pressure. I have done a lot of research into scented candles and this is what I found out about how scented candles work.
Scented candles work by releasing the scent through evaporation. As the wax on the surface of the candle heats up, it also heats the scent additive and releases it through evaporation. The burn process is similar to an unscented candle with the scent having little to no impact.
Due to the fragrance being released from the hot pool of wax and not from the flame itself this means larger candles, with more surface area are the best choice for a strong smelling candle.
How are scented candles made?
Scented candles are made from perfume, wax, a wick, and in some cases a candle container. The perfume is mixed with the wax so that it can be released as you use your candle. This is essentially the same process as a non-scented candle.
The combination of scent and wax is something that can take a little bit of research and trial and error. The perfumes and fragrances used in scented candles can impact the burn process.
A change in the burn process requires the candle manufacturer to adjust the wick size accordingly. This is to ensure that the candle burns evenly. If you want to read more about candles burning evenly you can check out an article I wrote about it here.
Where do the scents come from?
According to the National Candle Association, there are more than 2000 aroma chemicals and essential oils that are compatible with candle use. Many of these are also used in soaps, lotions, and shampoos.
Candle manufacturers and fragrance companies have put in a lot of work to develop formulas and candles that can burn safely and properly. You are seeing more and more natural scents, fragrances, and oils used in this process. Particularly if you find a reputable producer or brand.
It is said the original candles used in Europe were beeswax candles that included the sweet smell of honey as they were burning.
How safe are scented candles?
Scented candles are reasonably safe for most people to use and enjoy. The issue arises when you look at the type of candles, the source of candles, and if the person using the candle has any medical conditions.
If you have a respiratory disorder such as asthma, COPD, breathing complications or lung cancer you should avoid anything that may potentially complicate your situation.
You should read the candle label for any pertinent warnings and check to make sure it was made by a reputable manufacturer. You can also check to see if it was made using all-natural ingredients.
Type of Candles
There are basically three types of candle wax that candles are made out of today. They are paraffin, soy, and beeswax. Then you have a few blends of these wax types that are sometimes sold.
Paraffin wax is the cheapest of the three waxes and it is a petroleum byproduct. It is likely the least safe of the three types of wax. Studies have shown that paraffin wax can release carcinogens, as well as be harmful to people with respiratory disorders such as asthma.
Soy wax is made from processing soybean oil. It is all natural and vegan. It is cheaper than beeswax but it is slightly more expensive than paraffin wax. Soy is considered safe and clean.
Beeswax is a natural wax produced by honeybees. It is the most expensive wax on the market and it is said to be the cleanest burning with the brightest flame.
You will also find blends that can be any combination of the three.
Finding all-natural scented candles
You can find brands that produce the highest quality candles. Some of these candles are vegan with all-natural ingredients.
Some of these brands are:
- P.F. Candle Co
- Boy Smells
- Wild Beautiful Free
For the most part, candles are not regulated, but most companies adhere to industry consensus standards. Here is some information on the industry standards from ASTM International here.
Scented Candle Care Tips
Keep your candle smelling great and lasting as long as possible by following some of these scented candle care tips.
How To Take Care Of Your Candles
- Keep The Lid On It
- Keep The Wick Trimmed
- Let The Wax Pool
- Store The Candles Properly
Keep The Lid On it
Remember your candle has an additive that most candles do not. That is the fragrance or scent that was added to make it smell great.
Keep the lid on your candle whenever it is not being used so that it does not dry out. The scent additive in your candle can dry out and lose its oomph if you leave it setting without a lid for long periods of time.
This also keeps out the dirt, dust and grime that can make your candle dirty and give it an unpleasant smell.
If you are using a pillar candle or something that is not in a container that closes just put the candle in a freezer bag after it cools.
Keep The Wick Trimmed
Trim the wick after every use to make sure you get a steady uniform flame on every burn. Keep it no longer than 1/4 of an inch.
If you let the wick get too long it will build up carbon and become deformed and this will give you an irregular flame. This irregular flame can make your candle produce soot and it can even mix in with the wax.
If this happens your candle may develop a burnt smell.
Let The Wax Pool
Let the wax melt across the surface of the candle from one edge of the container to the other to prevent any wax tunneling issues.
Do this every time you use the candle, but do not let it burn longer than 4 hours.
Store The Candles Properly
Store the candle in a cool dry place away from direct sunlight. Temperature and light can affect the color and the scented oils in your candle.
A cupboard or box will be sufficient.

Scented candles do smell good when they are not lit. The scent you smell when a candle is not lit is called the cold throw and some candles have a cold throw that can rival the hot throw of other candles. The hot throw is the smell of a candle while it is burning.

Scented candles can sometimes not smell as good when they are burning because of impurities and dust that settle on the surface of the candle.
