Buying scented candles: how to compare fragrance profile, burn time and safety

Scented candles combine home fragrance with warm light. When shopping online, however, design alone does not determine how practical a candle is for everyday use. If you choose based only on the glass, colour or brand name, you can easily overlook important details about wax type, wick, burn time and safety.

Three common buying problems occur particularly often:

• Unclear burn time: Claims such as “long-lasting” are difficult to assess without a figure in hours. Depending on the wax, number of wicks and how it is used, a large scented candle in a glass jar can burn for different lengths of time.
• Unsuitable fragrance profile: A sweet scented candle with vanilla, baked-goods and spicy notes will seem much more intense in a small flat than a light, floral scented candle. Fragrance notes should suit both the room and your personal preferences.
• Time-consuming wick care: A wooden wick sounds appealing and can crackle as it burns. However, it needs to be trimmed to the recommended length and cleared of residue before every use.

Details to check before buying

1. Fragrance family and fragrance notes

Descriptions such as aromatic candles or candles for a cosy atmosphere are fairly general to begin with. The individual notes provide much more useful information:

• Floral: Rose, magnolia, peony and jasmine are ideal for shoppers looking for a floral and generally lighter fragrance profile.
• Sweet and gourmand: Vanilla, baked-goods, caramel, coconut and praline notes evoke desserts and often suit autumn and winter evenings.
• Warm and woody: Amber, sandalwood, musk and patchouli create a deeper, more spicy fragrance profile.
• Fresh: Citrus, cotton, green notes and aquatic accents are often chosen for kitchens, bathrooms or warmer seasons.

Also look out for the distinction between top, heart and base notes. Top notes are noticeable when you first smell the candle, while heart and base notes determine how the fragrance develops afterwards.

2. Wax, number of wicks and size

The net weight helps you compare similar products. The selection includes, for example, containers with 200 g, 454 g or 567 g. A higher weight does not automatically mean a longer burn time, as the number of wicks and the wax blend also play a role.

A large scented candle in a glass jar with two wicks can heat the surface more evenly. However, it needs enough space and should only be placed on a stable, heat-resistant surface. A single candle with a wooden wick, on the other hand, can provide an additional acoustic element through its crackling sound.

Product details list different wax blends, including:

• soy wax blends,
• paraffin,
• combinations of paraffin and soy wax,
• other wax components depending on the product.

It is therefore important to compare net weight, wick type and stated burn time together. Some large candles are listed as burning for around 60 to 90 hours or for up to 80 hours. These figures are guidelines provided for the respective product and depend on correct use.

3. Safe use in the home

Practical safety precautions apply to scented candles regardless of the brand or fragrance:

1. Place the candle on a level, stable and heat-resistant surface.
2. Keep it away from curtains, paper, furniture edges and other flammable materials.
3. Never leave candles burning unattended and keep them away from children and pets.
4. Trim the wick to approximately 5 mm before lighting, unless the product instructions state otherwise.
5. During the first burn, the layer of wax should ideally melt evenly all the way to the edge. This can help reduce tunnelling.
6. Observe the maximum burn time per use. For several products, this is no more than four hours.
7. Do not burn the candle all the way down to the base of the glass. It is often recommended to stop when around 1 cm of wax remains.
8. Do not move the glass during or after burning while the wax or container is hot.

For fragrance ingredients, the information on the label is authoritative. Some products may contain substances that can cause allergic reactions. Anyone with a relevant sensitivity should check the ingredient information before buying.

Scented candle FAQs

How long should a scented candle burn at a time?

Many product instructions specify a maximum burn time of four hours per use. During the first burn, the top layer of wax should ideally melt evenly. Before lighting it again, trim the wick and remove any residue.

How can you prevent a scented candle from tunnelling?

When using the candle for the first time, let it burn until the surface has largely melted all the way to the edge. Afterwards, avoid very short burning intervals. A wick that is too long can contribute to a higher flame, soot formation or uneven burning.

Are scented candles suitable as gifts?

Scented candles make practical gifts when the fragrance profile suits the recipient. If you are unsure of their preferences, neutral, fresh or floral notes are good choices. For Christmas and the colder months, Christmas candles, autumn-scented candles or sweet blends with cinnamon, vanilla and baked-goods notes are often a good fit. If the recipient has allergies or is sensitive to fragrances, the ingredient information should be taken into account.
