UV Inhibitors Protect Candle from Fading

For many, the summer will be winding down shortly and the kids will be heading back to school. As more time is spent inside, the need to put sun block on is greatly reduced but, did you know candles should always use some type of UV inhibitor?

Unfortunately, the same sun which brings us the beautiful days will cause havoc on our candles. Candle makers everywhere are forced to hide their beautiful masterpieces in an effort to keep their candles from fading or melting in the warm heat. There are a few simple tips and candle wax additives that can help protect your candles from the damaging rays of the sun, resulting in increased shelf life as well as raising your candle’s marketability as a premium product.

Ultraviolet Light Absorbers
UV inhibitors and Ultra Violet Light Absorbers (UVLA) were designed to reduce the fading of candles that are displayed in natural or artificial light. Think of them as sunscreen for your candles. Ugly fading (photo degradation) can be caused by a variety of factors, but nearly always can be avoided by the addition of UVLA.

Usage levels vary greatly depending upon application, but a general rule of thumb for large batches is to use about 45 grams of UV inhibitor per 100 pounds of wax. Smaller batches use 1/2 teaspoon to 10 lbs of wax. Some testing will be required for different colors to maximize effectiveness.

Some candle makers view UVLA as an unnecessary increase in the cost of materials while others realize the value of UVLA as an extremely simple way to increase the shelf life of their candles. On average, UVLA only costs about 4 or 5 cents per gram, which equates to less than $2.25 per 100 pounds of wax (just over 2 cents per one pound candle). You can even announce the added value protection on your label and charge an extra 50 cents per candle. That is over 2000% mark-up on investment!
