The Science and Selection Tips for Scented Candles

The Science Behind Scented Candles

Scented candles release fragrance into the air through burning, which can have various effects on the mind and body. Here, we will discuss the ingredients of scented candles, how fragrance is released into the air, the therapeutic effects of candle scents, and the environmental and health impacts of burning candles.

Ingredients and Materials

The primary component of scented candles is wax, typically made from paraffin, soy, beeswax, or palm wax. Soy wax is favored in high-end scented candles for its clean-burning and environmentally friendly qualities. Essential oils are key to the fragrance released during burning. Essential oils can be natural plant extracts or synthetic fragrances. Natural oils are preferred for their therapeutic properties, while synthetic fragrances offer a wide variety of scents and stability.

Wicks are usually made from braided cotton, though some products use wooden wicks. Cotton wicks burn slowly and evenly, while wooden wicks provide a crackling sound reminiscent of a campfire and add a unique touch. Both types of wicks serve to melt the wax and gradually release the fragrance.

Fragrance Release Mechanism

When the candle is lit, the heat from the flame melts the wax near the wick. The liquid wax is drawn up the wick through capillary action.

As the wick burns, the liquid wax near the flame evaporates, releasing fragrance molecules into the air. The type of wax and the composition of the essential oils affect the rate and intensity of fragrance release.

Therapeutic Effects

When fragrance molecules are inhaled, they reach the olfactory receptors in the nose and send signals to the brain, particularly the limbic system. The limbic system is associated with emotions, memory, and mood, explaining why certain scents can trigger emotional responses and memories. Essential oils used in scented candles, such as lavender, eucalyptus, and lemon, are known for their calming, refreshing, and invigorating properties. Scented candles can reduce stress, improve mood, and even have mild analgesic effects.

Environmental and Health Considerations

High-quality scented candles made from natural waxes like soy or beeswax burn cleaner than paraffin, producing less soot and harmful substances. Some essential oils, like tea tree oil, have antimicrobial properties that can help purify the air and reduce bacteria and pathogens.

How to Choose the Best Scented Candle

Here are some tips for selecting the right scented candle. These tips are useful whether you have a specific scent in mind or are still deciding:

Type of Wax
- Soy Wax: Natural, eco-friendly, burns cleanly. Ideal for those who prioritize environmental and health considerations.
- Beeswax: Natural, burns longer, and releases a more natural fragrance. Suitable for those seeking high-quality, natural products.
- Paraffin: Common but may release harmful substances. Check for quality and purity.
- Palm Wax: Relatively eco-friendly but may involve environmental issues in production.
Source of Essential Oils

Natural Essential Oils: Such as lavender, sandalwood, and orange blossom, often have therapeutic effects. Ideal for those sensitive to natural ingredients or seeking aromatherapy benefits.
Synthetic Fragrances: Offer a broader range of scents at a lower price, but may contain chemical components.
Burn Time and Effectiveness
- Burn Time: High-quality candles generally have a longer burn time. Check product descriptions to choose an appropriate burn duration.
- Fragrance Strength: Different candles offer varying fragrance intensities. Select according to your personal preference.
Environmental and Health Factors
- Non-Toxic Ingredients: Ensure the candle does not contain harmful chemicals like benzene or formaldehyde.
