Candles have long been used to create ambiance and warmth in our homes. But sometimes, we notice that the once-white or clear wax has turned yellow. Let's look at the reasons behind this and explore how we can prevent it.
Reasons for Yellowing
There are a few main reasons why candle wax can turn yellow over time:
Exposure to Air: When candles are exposed to air, a process called oxidation can occur. This is simply a reaction between the wax and the oxygen in the air. The result can be a yellowish color that develops over time.
Sunlight: Sunlight, especially its ultraviolet (UV) component, can cause the color of the wax to change. The sunlight can break some of the bonds in the wax, creating new compounds that may have a yellowish tint.
Impurities: Sometimes, the wax in candles can contain impurities or additives that cause the color to change. For example, beeswax is naturally yellow, and when it's mixed with other types of wax, it can cause the final product to have a yellowish color. Other impurities, such as dyes or fragrances, can also contribute to the yellowing process.
How to Prevent Yellowing
Here are some simple tips to help you keep your candles looking fresh and avoid the yellowing process:
Store in a Cool, Dark Place: Keeping your candles away from direct sunlight and heat sources can help prevent yellowing. Store them in a cool, dark place, like a cabinet or a drawer, to minimize exposure to light.
Choose High-Quality Candles: Investing in high-quality candles made from pure wax with minimal impurities can help prevent yellowing. Look for candles that use natural ingredients, like soy or beeswax, and avoid those with added dyes or synthetic fragrances.
The yellowing of candle wax is a natural process that can result from exposure to air, sunlight, and impurities. By understanding these factors and taking preventive measures, you can keep your candles looking their best for longer. Enjoy the warm glow and soothing ambiance of your candles without the worry of yellowing wax.
