Choosing the right scent is one of the most important decisions in candle making. The type of oil you use affects how strong the candle smells, how it performs when burning, and even how consistent your results are. The two main options are fragrance oils and essential oils, and while they may seem similar, they behave very differently in candles.
Understanding Candle Scent Options
Scent gives a candle its personality. It can be calming, energising, warm, or fresh. In candle making, scents generally come from either essential oils or fragrance oils. Both can be used, but they serve different purposes and suit different goals.
Understanding how each type works will help you choose the best option for your candles, whether you are making them for relaxation, gifting, or selling.
What Are Essential Oils?
Essential oils are natural extracts taken from plants, flowers, leaves, bark, or fruit peels. Common examples include lavender, eucalyptus, peppermint, lemon, and tea tree. They are often associated with aromatherapy and natural wellness products.
In candles, essential oils offer a subtle and natural scent. However, many essential oils are sensitive to heat, which means their fragrance can fade during the candle making process or while the candle is burning. This can result in a lighter scent throw compared to other options. Essential oils are also usually more expensive and have a narrower scent range.

What Are Fragrance Oils?
Fragrance oils are specially formulated blends that may contain synthetic aroma compounds, natural components, or a combination of both. They are designed to be stable, consistent, and effective in scented products like candles, soaps, and diffusers.
One of the biggest advantages of fragrance oils is variety. They can recreate natural scents or produce complex blends that do not exist in nature, such as baked goods, perfumes, or seasonal fragrances. Fragrance oils are also designed to perform well under heat, making them a popular choice for candle makers.
Performance in Candle Making
When it comes to performance, fragrance oils generally outperform essential oils in candles. They are formulated to handle high temperatures and provide a stronger and more consistent scent throw, both when the candle is cold and when it is burning. This makes them ideal for filling a room with fragrance.
Essential oils, by contrast, can lose strength when exposed to heat and may require higher usage rates, which can affect burn quality. For makers who prioritise scent strength and reliability, many turn to options like candle fragrance oils that are specifically created for candle performance.
Safety and Allergies
Both fragrance oils and essential oils can be safe when used correctly, but neither should be assumed to be risk free. Essential oils are highly concentrated and can cause skin irritation or sensitivity in some people. Fragrance oils designed for candle making are tested for safe usage levels and usually come with clear guidelines.
Regardless of the oil type, it is important to follow recommended usage rates and ensure the oil is suitable for candle use. Proper ventilation and quality wicks also play a role in safe burning.
Which One Should You Choose?
The right choice depends on your goals. If you are making candles mainly for aromatherapy or prefer natural ingredients with a subtle scent, essential oils may suit your needs. If you want strong scent throw, creative freedom, and consistent results, fragrance oils are often the better option.
Many candle makers experiment with both to see which works best with their wax, containers, and personal style. Beginners often start with fragrance oils because they are easier to work with and more forgiving.
Last Thoughts
Fragrance oils and essential oils both have a place in candle making, but they offer very different results. Essential oils provide a natural and gentle aroma, while fragrance oils deliver strength, variety, and reliability. Understanding these differences allows you to make informed choices and create candles that meet your expectations every time.
