You have probably seen this indicator in descriptions of flavorings, but not everyone knows why it is important to pay attention to the percentage of vanillin and what it depends on.
Have you ever experienced that when you pour candles or make soap, you follow the instructions, and after some time of solidification, you notice that the color of your wax or soap has noticeably "yellowed"? In most cases, vanillin is to blame for this☝️

A visual example of vanillin content in a fragrance.
2. What is the content of vanillin in fragrances?
The content of vanillin in fragrances can vary; for CandleScience aroma oils, there are several indicators:
- 0%;
- from 0.01% to 2%;
- from 2.01% to 5%;
- over 5%.
The higher the percentage of vanillin, the more intensely your wax will color, from light cream to cream-brown.
It's also noticeable in the fragrances themselves - some are almost transparent, while others are intensely yellow or brown.
3. Tips for candle makers when working with fragrances containing vanillin:
🔹 Accept it and get used to it. Yes, your candles will have a slightly different warm color, but most customers won't even notice it, I assure you 😉
🔹 Add a little ivory-colored dye to balance the color.
🔹 Reduce the percentage of adding this fragrance.
But if having a white wax is essential for you, we advise not to use fragrances with high vanillin content❌️
4. General recommendations for working with fragrances with high vanillin content:
🔹 Wait for a period of 2 weeks to a month, observing color changes;
🔹 Take into account the characteristics of the fragrance and use them to your advantage.
5. Using fragrances with high vanillin content in soap making.
Soap made from scratch or soap base is also very sensitive to vanillin and can change color significantly, from light cream to brown even after a few weeks. This happens in part due to the presence of alkali in the soap, which reacts with vanillin.
Tips for soap makers when working with fragrances containing vanillin:
🔹 In cold process soap - accept it and use the color change to your advantage by creating swirl designs or pouring multiple colors, for example, leaving some portions without fragrance.
🔹 Use a vanillin stabilizer (only for soap, DO NOT USE FOR CANDLES!!!).
