What is the use of UV Absorbers in the process of Candle making ?
UV Absorbers or Ultra violet Absorbers are commonly used in the candles to protect them from Fading or Degradation. Very small amounts of UV Absorbers are added to colored and scented wax blends to help reduce the degradation (fading) that occurs when candles are exposed to fluorescent light and sunlight. They work by absorbing more of the UV waves or energy than candle itself.
Two common UV absorbers used in the process of candle making are :
These two absorbers can be used both ways individually or combinedly. But it is recommended to use it combinedly because they both offer protection in different wavelength regions or different ends of colour spectrum.
Although a candle can never be totally protected from sunlight and different dye/wax/fragrance combinations can pose significant fading problems, it is certainly advisable to incorporate UV Light Absorbers into all of the wax formulations to extend the life and beauty of your candles.
