Is it normal for scented candles to have black smoke? What causes scented candles to emit black smoke?

Scented candles are a product that we all like very much, but many people who are familiar with scented candles know that scented candles do not emit black smoke. So we need to understand whether it is normal for scented candles to emit black smoke? What are the reasons for scented candles to emit black smoke?

Is it normal for scented candles to have black smoke?

Abnormal. Good scented candles are smokeless under normal use. But some poor quality scented candles will have a faint black smoke, or the improper use of scented candles will cause black smoke. I have been using scented candles for many years, and I have tried almost all kinds of wax, such as paraffin, beeswax, soy wax, etc. But no matter what type of candle, try not to use it in a ventilated place. The candle flame will sway in the wind all the time. When the wind blows, the flame temperature will be low, making the candle burn incompletely, and then produce carbon black, which is black smoke. After each burn, the candle wick will turn black. If it is not trimmed in time, the overlong candle wick will make the candle burn incompletely, and even some black particles will fall off to pollute the wax pool, and then produce black smoke. So be sure to cut off the overlong candle wick before each use to avoid black smoke.

Reasons why scented candles emit black smoke

1. The wick is too long: The wick of some scented candles is relatively thick. After burning for a long time, there will be black powder in the wax pool, which will form black smoke when burning. It is recommended to cut off the long wick before each use, or use a candle extinguisher to extinguish it.

2. Paraffin wax base: There are several types of base wax used in scented candles on the market, the most common ones are paraffin wax, coconut wax, soy wax, etc. However, because paraffin wax is cheap, many manufacturers will choose it as the base of scented candles. However, due to the material, paraffin wax will produce black smoke.

When the wick of a scented candle is too long, the flame will be too high, which will accelerate the consumption of the candle. Uneven heating will also cause black smoke, which will blacken the candle wall. It is recommended to trim the wick of the scented candle to 3-5 mm before lighting it. Note that trimming should be done before lighting. Trimming after lighting will cause dust to fall into the wax pool, which is inconvenient to clean.

Do scented candles have a scent?

Yes. Fragrances are added during the production process of scented candles. Good scented candles can smell a faint fragrance before they are lit. When lit, the wax block is heated, the temperature of the fragrance rises, the volatilization speed is accelerated, and the fragrance molecules are diffused in the air. At this time, we can smell a strong fragrance. As time goes on, the candle melts, and the fragrance will gradually fade until it dissipates. Of course, as the aroma candle is lit for a longer time, the fragrance will change. If you taste it carefully, you will find that the fragrance will be different at different time periods, not only the difference in intensity, but also the difference in fragrance type. This is the so-called front, middle and back notes of the fragrance. In fact, aromatherapy essential oils or fragrances are decomposed and unscented under the high temperature of the flame, but the temperature of the melted wax pool around the flame rises, but it is not high enough to decompose the fragrance. At this time, it promotes the volatilization and diffusion of the fragrance into the air. More professional aromatherapy candle brands, such as voluspa, have a small circle of fragrance around the candle when it is not lit, and it will indeed fill the room with fragrance after it is lit.

Do scented candles have the effect of removing formaldehyde?

No, scented candles can only temporarily cover up the smell of formaldehyde, but cannot completely remove formaldehyde. The volatilization time of indoor formaldehyde is relatively long, generally about three to ten years. And the maximum time for scented candles to be smoked is about four hours, so it is impossible to rely on scented candles to remove formaldehyde. Scented candles can also burn off some organic pollutants while burning. The ash produced by candles is a good charcoal ash material with strong adsorption function. But this statement is somewhat controversial. Although burning candles can burn off some pollutants, scented candles can't burn much. Gray smoke can't absorb much either, and gray smoke itself is also a pollutant for humans. If you want to remove odors quickly, you should ventilate more or use activated carbon for adsorption.
