When it comes to how to scent your handmade candles, there are two voices: essential oils and fragrance oils. Though both essential oils and fragrance oils can be used for candle making, they are not similar in performance. Besides, the debate between essential oils and fragrance oils also involves health and safety.
Essential Oils vs. Fragrance Oils for Candle Making Chart
| Feature | Essential Oils | Fragrance Oils |
|---|---|---|
| Source | Extracted from natural plants (flowers, leaves, bark, roots, etc.) | Lab-synthesized from aromatic compounds; may include some natural components |
| Production Method | Steam distillation or solvent extraction | Chemical formulation and blending in lab |
| Natural vs. Synthetic | 100% natural | Typically synthetic or a blend of synthetic and essential oils |
| Variety of Scents | Limited to what can be extracted from real plants | Extremely wide, including fantasy or food-inspired scents (e.g., vanilla, ocean breeze, cotton candy) |
| Scent Throw (Cold) | Light to moderate | Moderate to strong |
| Scent Throw (Hot) | Generally weak to moderate; varies due to natural complexity and evaporation rates | Strong and long-lasting; designed for hot throw performance |
| Health Benefits | May provide aromatherapy effects like calming, uplifting, and focus enhancement | No proven therapeutic effects |
| Safety (IFRA Compliance) | Safe when used properly and in moderation; some may be dermal irritants | Most are IFRA-compliant and safe for candle use; always check label |
| Shelf Life | 2 to 15 years (depending on oil type and storage) | 6 to 12 months (more prone to degradation over time) |
| Stability in Wax | Can be unstable in high heat or certain wax types (e.g., soy) | Highly stable and formulated for various candle waxes |
| Performance Consistency | Varies by harvest, origin, and plant type | Highly consistent due to lab-controlled formulas |
| Flash Point | Often low (some below 150°F / 65°C) | Generally higher (often over 170°F / 77°C), safer for hot wax handling |
| Price | More expensive due to low yield and production complexity | Affordable and cost-efficient, especially in bulk |
| Phthalate-Free Options | Typically free of phthalates | Widely available in phthalate-free versions |
| Suitability for Beginners | Requires more knowledge on usage, flash points, and load limits | More beginner-friendly due to forgiving formulation and stronger performance |
Our Opinion
Fragrance oils outperform essential oils in scent throw, versatility, price, and consistency, making them ideal for most candle makers, especially beginners or those selling products.
Essential oils, while more expensive and sometimes weaker in scent, offer natural ingredients and potential wellness benefits, making them a better fit for those prioritizing natural living or aromatherapy.
Briefly, fragrance oils are better than essential oils in candle making because of their scent throw and affordable price. As for health, it is more of a personal choice.
Now, let’s take a closer look at the two: essential oils vs. fragrance oils for candle making.
Key Difference: What Fragrance Oils and Essential Oils are Made of
The key difference between essential oils and fragrance oils lies in their ingredients.
Essential Oils
Essential oils are the essence of aromatic plants, usually flowers, leaves, roots, and others, extracted through the process of distillation or solvent extraction. They are natural, highly concentrated, and fragrant of course.
Fragrance Oils
Unlike essential oils, fragrance oils are synthetic products from the laboratory. Fragrance oils are a compound of natural fragrances (usually essential oils), aroma chemicals (from a lab), diluents, and carriers.
Scent Options
As essential oils are extracted from plants in nature, the types of scents are great but not endless. The most commonly used in candles include: lavender, bergamot, sandalwood, rose, peppermint, lemon, lemongrass, eucalyptus, tea tree, etc.
Fragrance oils offer a wider range of scent options, if not infinite, as they are mixed in the lab. You can find some scents that only exist in fragrance oils. For example, you may like the scent of vanilla, but you can only make vanilla-scented candles with fragrance oils.
Scent Throw
Though candles made with either essential oils or fragrance oils smell good, essential oil candles generally have a lighter scent when compared with fragrance oil candles.
Essential oils are natural and also complex in the sense of chemical components. These components evaporate at different rates and temperatures, thus it’s hard to have an excellent hot throw.
Because fragrance oils are made in the lab, the aroma compounds are formulated to achieve the best performance. Besides, the chemical formula is always the same, they will have a consistent scent.
Generally speaking, with the same amount of essential oils and fragrance oils in candles, you’ll get a much stronger scent in fragrance oil candles.

Safety
Though essential oils and fragrance oils are made of different ingredients, both oils are safe for our health. That is the bottom line.
Some people may argue that fragrance oils are synthetic, synthetic things are toxic to our health.
In fact, the fragrance oils you can find on the market are qualified to be used in candles. Before they are mass-produced, they must pass the test from IFRA which examines the ingredients.
Health Benefits
People using essential oils for candles are mainly attracted by the potential health benefits of essential oils. Simply put, essential oils are great aromatherapy choice because they can boost energy, calm nerves, heal congestion, improve sleeping quality and tackle fatigue. If you want such effects, essential oils will be a good choice.
Though there’s no evidence that fragrance oils also have such health benefits, they are not harmful, either. Some fragrance oils may contain phthalates, which are not good for health. If you don’t like that, there’re still lots of choices that have no phthalates.
Shelf Life
Generally, essential oils can last longer because they are derived from natural plants. Their shelf life varies from 2 years to 15 years, depending on the plants they are derived from.
The average shelf life of fragrance oils is from 6 to 12 months under proper conditions, such as in a dark, cool place.
Price
It’s clear that essential oils are more expensive than fragrance oils because of their natural source and really low yield.
Conclusion
Essential oils and fragrance oils both have their advantages and disadvantage. When added to candles, fragrance oils perform better than essential oils in scent throw. However, if you prefer healthier scented candles, essential oils can also be a nice choice.
