How a candle gives off scent
The NCA says scent is released by evaporation from the hot wax pool and from the solid candle itself.
What fragrance oils are made of
The NCA says most scented candles combine natural and synthetic fragrance. Materials may come from essential oils or synthetic aroma chemicals.
Approved for candle use
The NCA says a well-made candle contains only fragrance materials approved for candle use, and the amount should be carefully monitored.
Read the Safety Data Sheet
OSHA requires chemical makers, importers, and distributors to provide Safety Data Sheets for hazardous chemicals in a 16-section format. Section 2 covers hazards, Section 5 fire fighting, Section 7 handling and storage, and Section 9 properties such as flash point.
How much fragrance?
The NCA says the amount should be carefully monitored. Use the fragrance and wax makers' instructions for the amount. We do not give a number.
FAQ
General information only. Never leave a burning candle unattended, and keep it at least 12 inches from anything that can burn. When you heat wax, stay with it, and turn off the heat if you leave or see smoke. Never use water on a wax fire. If you can do so safely, slide a lid over the pot and turn off the heat; if the fire does not go out, get everyone out and call 911 from outside. Read and follow the Safety Data Sheet and instructions from the maker of every wax, wick, fragrance oil, and dye you use.
