"Why do some candles turn yellow?"

Why do some of our candles turn yellow??


At Tappen Apothecary, we pride ourselves on using simple ingredients to create high-quality, hand-crafted, affordable, and non-toxic products for you. This is why we have opted to develop dye-free candles. By avoiding the use of dye, we are reducing the number of different particles released into the air when you use our products. Furthermore, like many products, dyes will fade over time when placed in natural or artificial light, which would only prolong the inevitable yellowing.


So you might be wondering, why would you need to use a dye anyway if the wax is already white, and why doesn’t it happen to every candle? Well, think about the way natural light affects fabric. Over time, some material left out in the sun will eventually get a yellowish tint. This also happens to certain fragrance oils. Specifically fragrances with high vanillin content, some floral scents, and many citrus scents. Vanillin is the primary component of the extraction of vanilla beans, but modern manufacturing processes have found more efficient ways to produce it. Candles like Tobacco and Whiskey with a base note of vanilla will fall victim to this yellowing since the fragrance has a high vanillin content.


Despite the yellow appearance, all our candles will burn the same as if they did not change colour (don’t worry, we have tested this). Moreover, avoiding the use of additives helps us keep the price of our products more affordable! We hope this answers any questions you have about why our candles turn yellow, and if you have any more questions, please email us at tappenapothecary@gmail.com. We LOVE receiving your feedback because it helps us to create better products for you, which is our mission!
