Paraffin wax or 'mineral' wax is derived from petroleum which is drilled out the ground from oil rigs and refined. It is considerably the most popular choice for candle makers. But there are still some people who doubt its security.
Paraffin wax is very safe to make candles. You can know from the following aspects:
Paraffin is a mixture of hydrocarbons, so it does not have a strict melting point like a pure compound, and is generally divided into different varieties, such as 52, 54, 56, 58 grades, every 2 °C.
According to the change of different seasons and regions, you need to choose high melting point paraffin wax or low melting point paraffin wax.
The order of oil content is as follows: scale paraffin>semi refined paraffin>fully refined paraffin>food grade paraffin.
The oil content will directly affect the burning effect. The higher the oil content, the better the burning effect. This is why some bad merchants use crude paraffin to make candles.
But the common choice is to use fully refined paraffin wax or semi refined paraffin wax. The finished candle is of better quality and is safe to use.
Polycyclic aromatic hydrocarbons are contained in crude oil and cannot be completely removed. This substance is the source of "carcinogenic" speech and is also a substance confused with "benzene". benzene is carcinogenic, but fused aromatic hydrocarbons are not benzene.
Besides, because of deep refining degree, fully refined paraffin wax has no impurities and little polycyslic aromatic hydrocarbons,which will not have bad effect on our body.
