Let’s dive in!

Key Takeaways:

  • Scented candles create their aromatic magic through a combination of heat, wax, and fragrance oils. When lit, the heat melts the wax, allowing the fragrance oils to vaporize and release their scent into the air, creating a soothing and aromatic atmosphere.
  • Different types of waxes—paraffin, soy, beeswax, and blends—affect how a candle burns and releases fragrance. Paraffin has a strong scent throw, soy burns cleaner and longer, beeswax has a natural scent, and blends offer enhanced fragrance release and burn time.
  • Scented candles use both natural and synthetic fragrances. Natural fragrances, derived from plants and flowers, offer authentic aromas and therapeutic benefits. Synthetic fragrances, created in labs, provide a wider range of consistent and long-lasting scents at a lower cost.
  • Scented candles reduce stress, enhance mood, improve sleep quality, boost cognitive function, create soothing ambiances, enhance home décor, and support healthy habits. Scents like lavender, citrus, and rosemary play specific roles in providing these benefits.
  • To get the most from scented candles, trim the wick to 1/4 inch before each use, allow the wax to melt evenly across the surface, avoid drafts, use a candle snuffer to extinguish the flame, and store candles in a cool, dry place to preserve their fragrance and longevity.

How Do Scented Candles Work?

How Do Scented Candles Work

Scented candles work through a fascinating process involving the interaction of heat, wax, and fragrance oils. Here’s a detailed breakdown:

The Fire Triangle

For a flame to sustain itself, it needs three elements: oxygen, heat, and fuel. In the case of scented candles, the fuel is the wax, and the heat comes from the burning wick.

Melting the Wax

When you light the candle wick, the heat from the flame melts the wax near the wick. This melted wax is then drawn up the wick through capillary action. As it gets closer to the flame, the wax turns into a gas and ignites, producing both light and heat.

Releasing the Fragrance

The heat generated by the flame also heats the fragrance or essential oils embedded in the wax. As these oils heat up, they vaporize, releasing aromatic molecules into the air. This evaporation from the hot wax pool, or melt pool, is what gives off the scent.

Ensuring an Even Burn

To get the best scent experience, it’s crucial to let your scented candle burn until the entire surface has melted. This creates a full melt pool, which helps to release the fragrance evenly. Make sure to burn your candle on a flat surface and keep it away from drafts to achieve this.

Wax Types and Their Impact

The type of wax used in a scented candle affects its burning process and scent throw:

Paraffin Wax

Derived from petroleum, known for strong scent throw and even burning.

Soy Wax

Made from soybeans, it burns longer and cleaner, making it environmentally friendly.


Natural and slow-burning, beeswax emits a light honey scent.

Blended Waxes

Combinations like paraffin and soy can enhance burn time and fragrance release.

Importance of the Wick

The wick plays a critical role in how well a candle performs. Usually made of cotton, the wick’s size and material are chosen based on the candle’s specifications. The right wick ensures proper combustion, preventing issues like tunneling (where the candle burns down the middle, leaving wax around the edges) and excessive smoke.

By understanding these elements, you can appreciate how scented candles work and enjoy their aromatic benefits fully.

Where Does the Scent Come From?

The captivating aroma of scented candles comes from carefully crafted fragrance sources. Understanding these sources and how they are extracted can help you appreciate the art and science behind the scents.

Types of Fragrance Sources

Fragrance SourceDescription
Natural FragrancesDerived from plants, flowers, herbs, and spices, natural fragrances include essential oils like lavender, rose, and citrus fruits. Known for authentic aromas and potential therapeutic benefits.
Synthetic FragrancesCrafted in laboratories, synthetic fragrances replicate natural scents or create new ones. They offer a wide range of aromas, are often more affordable, and provide consistent and long-lasting scent profiles.

Natural Fragrances

Derived from the bounties of nature, natural fragrances encompass a wide array of scents extracted from plants, flowers, herbs, and spices. They include essential oils meticulously obtained from botanical sources such as lavender, rose, eucalyptus, and various citrus fruits. Known for their intricate and authentic aromas, natural fragrances also offer potential therapeutic benefits, contributing to both olfactory pleasure and well-being.

Synthetic Fragrances

In contrast, synthetic fragrances are the product of human ingenuity, crafted within laboratory settings using chemical compounds. Engineered to replicate the scents found in nature or to create entirely novel fragrances, synthetics present a vast spectrum of aromatic possibilities. They often prove more economical and versatile than their natural counterparts, with greater consistency and longevity in scent profiles. This controlled precision ensures a wide availability of scents to suit diverse preferences and applications.

Extraction Methods

Extraction MethodDescription
DistillationUses steam to extract essential oils from plant materials, yielding high-quality and pure oils. Ideal for various botanical sources.
ExpressionMechanical pressing of citrus fruit peels to extract oils, preserving their freshness and vitality. Produces bright and authentic citrus fragrances.
Solvent ExtractionDissolves plant materials in solvents to extract aromatic compounds, yielding concentrated oils known as absolutes. Essential for capturing delicate floral scents like jasmine and tuberose for scented candles.


Distillation stands as a time-honored method of extracting essential oils from plant materials, harnessing the power of steam to unlock their aromatic essence. Through careful heating, plant matter releases aromatic vapors, which are then condensed back into a liquid form. This process yields high-quality essential oils renowned for their purity and potency, making them prized ingredients in scented candles.


Also known as cold pressing, expression is particularly suited to extracting oils from the peels of citrus fruits. By subjecting the fruit peel to mechanical pressure, essential oils are expelled, capturing the vibrant and zesty essence of citrus. This gentle extraction method preserves the freshness and vitality of the oils, ensuring a bright and authentic fragrance.

Solvent Extraction

Solvent extraction offers a means of capturing delicate floral aromas that may not withstand the rigors of distillation. By dissolving plant materials in solvents, such as hexane or ethanol, aromatic compounds are extracted, yielding concentrated oils known as absolutes. While highly aromatic, these absolutes may retain trace amounts of solvent, requiring meticulous purification. Nonetheless, solvent extraction remains indispensable for capturing the intricate scents of flowers like jasmine and tuberose, enriching scented candles with their intoxicating fragrances.

By understanding the origins and extraction methods of fragrance sources, you can better appreciate the intricate process that goes into creating the delightful scents of your favorite candles.

Why Do Scented Candles Smell Different When Burning vs. Not Burning?

Scented candles often exhibit distinct fragrances when they are burning compared to when they are not. This difference is primarily due to the heat involved when the candle is lit, which initiates a process called scent diffusion.

When you light a scented candle, the heat from the flame melts the wax near the wick, causing the fragrance oils to evaporate. This evaporation transforms the fragrance oils into a gas, releasing them into the air and intensifying the scent. The molecular structure of the fragrance oils can also change due to the heat, slightly altering the scent profile compared to when the candle is unlit.

Additionally, a burning candle continuously releases scent due to the sustained heat, providing a more intense and consistent fragrance experience. This is different from the cold throw, which is the scent emitted from a candle when it is not lit. The cold throw tends to be subtler since it relies on the natural evaporation of the fragrance oils at room temperature.

Several factors influence the scent of a burning candle, including:

  • Type of Wax: Different waxes (soy, paraffin, beeswax, or blends) can impact how fragrance oils are released.
  • Fragrance Oil Concentration: The amount of fragrance oil in the wax affects the strength of the scent.
  • Wick Characteristics: The size and material of the wick influence how the candle burns and releases fragrance.
  • Burn Time and Temperature: Longer burn times and higher temperatures can enhance the scent diffusion process.

For the cold throw, factors such as the type of wax, the specific fragrance oils used, and the candle’s packaging play significant roles in the scent experienced when the candle is not burning.

Understanding the differences between the cold throw and the scent diffusion when burning can enhance your enjoyment and selection of scented candles. When choosing a candle, consider both its cold throw and the aroma it emits when lit for a comprehensive fragrance experience.

5 Best Tips for Maximizing Your Scented Candle Experience

Maximizing your scented candle experience goes beyond simply lighting a wick. By following a few key tips, you can ensure optimal burning, fragrance release, and longevity of your candles.

These five tips will help you get the most out of your scented candles, creating a soothing ambiance and enhancing your space with delightful aromas.

Trim the Wick for Optimal BurningKeep the wick trimmed to 1/4 inch to prevent soot and ensure an even burn, enhancing fragrance release and extending the candle’s lifespan.
Allow the Wax to Melt EvenlyLet the wax melt across the entire surface to prevent tunneling and maximize scent throw, resulting in a longer-lasting and more aromatic candle.
Avoid Drafts to Prevent Uneven BurningPlace candles away from drafts to maintain a steady flame and consistent burn, preventing soot formation and ensuring an optimal aromatic experience.
Extinguish the Candle CorrectlyUse a candle snuffer to extinguish the flame safely, minimizing smoke and preserving the scent for future use without splattering hot wax.
Store Your Candles ProperlyStore candles in a cool, dry place away from direct sunlight to maintain fragrance potency and prevent deterioration of wax and oils, ensuring a longer-lasting scent and lifespan.

1. Trim the Wick for Optimal Burning

Before lighting your candle, always trim the wick to about 1/4 inch. A properly trimmed wick ensures a clean and even burn, preventing the candle from producing soot and excessive smoke. This practice not only extends the life of your candle but also enhances the release of its fragrance.

2. Allow the Wax to Melt Evenly

When you light your candle for the first time, let it burn long enough for the entire surface to melt. This can take 2-4 hours depending on the size of the candle. Allowing the wax to melt evenly across the top prevents tunneling, where the candle burns down the center, leaving unused wax along the sides. A full melt pool maximizes the scent throw and ensures a longer-lasting candle.

3. Avoid Drafts to Prevent Uneven Burning

Place your candle in a spot free from drafts, fans, or air conditioning vents. Drafts can cause the flame to flicker, leading to uneven burning and soot formation. A stable environment ensures a steady flame and a more consistent burn, allowing you to enjoy the full aromatic experience of your scented candle.

4. Extinguish the Candle Correctly

To extinguish your candle, use a candle snuffer instead of blowing it out. Blowing out the candle can cause hot wax to splatter and may produce smoke and an unpleasant odor. A snuffer safely smothers the flame, minimizing smoke and preserving the scent for future use.

5. Store Your Candles Properly

Store your candles in a cool, dry place away from direct sunlight and intense indoor lighting. Excessive heat and light can cause the wax and fragrance oils to deteriorate, reducing the candle’s scent and lifespan. Keeping the lid on your candle when not in use can also help preserve the fragrance and prevent dust from accumulating on the surface.


Scented candles are more than just decorative items; they are a harmonious blend of science and art, designed to elevate your living space and well-being. By understanding the intricate process of how scented candles work—from the interaction of heat, wax, and fragrance oils to the different types of wax and their impacts—you can fully appreciate their aromatic magic.
