This comprehensive guide delves into the world of candle fragrances, providing you with the knowledge and tools to enhance your candle-making journey.
Types of Fragrances Used in Candle Making
Fragrance Oils
Fragrance oils are synthetic or blended scents created specifically for use in candles and other scented products.
- What are synthetic fragrance oils, and are they safe?

Understanding Fragrance Load and How to Calculate It
Fragrance Load Defined
The fragrance load is the percentage of fragrance oil relative to the weight of the wax.
- Why does fragrance load matter?
- It affects the scent strength and candle performance.
Calculation Method
- Formula: Fragrance Load (%) × Weight of Wax = Amount of Fragrance Oil
- Example: For 100g of wax at an 8% fragrance load:

- Create small test candles to evaluate scent throw and compatibility.
Understanding Flash Points
The flash point is the temperature at which the fragrance oil can vaporize to form an ignitable mixture.
- How does the flash point of a fragrance affect candle making?
- Adding fragrance below its flash point helps retain scent and ensures safety.
Proper Storage of Fragrance Oils
- Store in a cool, dark place in airtight containers.
- How does temperature fluctuation affect stored fragrance oils?

How Fragrance Affects Candle Performance
Scent Throw
Scent throw refers to how far the fragrance from a candle disperses in a room. It can be categorized as:
- Cold Throw: The scent given off by the candle when it is not lit.
- Hot Throw: The scent released when the candle is burning.
- What factors affect the hot and cold throw of a candle?
- Wax type, fragrance load, and the size of the room all play a role.
Burn Quality
- Can certain fragrances affect how long a candle burns?
- Yes, heavier oils can sometimes interfere with the wick’s ability to maintain a consistent flame.
Fragrance Load and Burning Issues
- How does fragrance load influence candle tunneling?
- Excessive fragrance can cause uneven burning, leading to tunneling where the wax burns down the center and leaves wax on the sides.
Can You Use Perfume or Cologne in Candle Making?
Understanding Perfume and Candle Safety
- Is it safe to put perfume in a candle?
- No, perfumes and colognes are not designed for high heat and may contain ingredients that are flammable or not safe to burn.
Alternatives to Perfume
- Use Fragrance Oils: Fragrance oils are designed to withstand the heat and burn safely in candles.
- How does the composition of perfume differ from fragrance oils?
- Perfumes contain alcohol and other volatile substances that evaporate at lower temperatures, whereas fragrance oils are formulated for burning in candles.
How to Make Scented Candles Last Longer
Candle Care Tips
- Trim the Wick: Ensure the wick is trimmed to 1/4 inch before every burn to prevent soot and uneven burning.
- Let the Wax Pool: Allow the wax to melt across the entire surface before extinguishing the flame to avoid tunneling.
- Does fragrance oil affect candle burn time?
- Yes, higher fragrance loads can reduce burn time slightly, but this can be mitigated by choosing the right wick and wax combination.
- What temperature should I store scented candles at to preserve the fragrance?
- Store in a cool, dark place to prevent the fragrance from dissipating over time.
Curing and Scent Preservation
- How long should candles cure to maximize fragrance strength?
- Allow candles to cure for at least 48-72 hours, though some may require up to two weeks depending on the wax type.
The Science Behind Scent Throw in Candles
How Scent Throw Works
The release of fragrance from a candle, known as the scent throw, is influenced by several factors, including the type of wax, wick, and fragrance used.
- What is the optimal fragrance load for soy wax, paraffin, and beeswax?
- Soy wax typically holds up to 10% fragrance load, paraffin can hold more, and beeswax holds less due to its natural density.
- Does the size of the room affect the perceived scent strength?
- Yes, larger rooms may dilute the intensity of the fragrance, requiring stronger scents or higher fragrance loads.
Flash Point and Scent Retention
The flash point of a fragrance oil, or the temperature at which it begins to evaporate, plays a crucial role in scent throw.
- What happens if a fragrance oil’s flash point is too low?
- The fragrance may evaporate during the candle-making process, resulting in a weaker scent throw.
