Walk into any homewares store or browse online, and you'll encounter candles made from a bewildering variety of waxes: soy, paraffin, beeswax, coconut, palm, and countless blends. Each type has its advocates and critics, and the marketing claims can be confusing. Is soy really better for the environment? Does paraffin actually produce harmful fumes? Should you pay extra for beeswax?

In this guide, we'll break down the most common candle wax types, examining their characteristics objectively so you can make informed decisions based on your priorities, whether that's burn time, scent performance, environmental concerns, or budget.

Paraffin Wax: The Traditional Choice

Paraffin wax has been the dominant candle-making material for over a century. Derived from petroleum, it's a byproduct of the oil refining process. While this origin has led to criticism from environmentally-conscious consumers, paraffin remains widely used for several practical reasons.

Advantages of Paraffin

  • Excellent scent throw: Paraffin holds and releases fragrance oils exceptionally well, producing strong hot throw (scent when burning) and cold throw (scent when unlit)
  • Consistent performance: Decades of refinement have made paraffin candles reliable and predictable
  • Affordable: As a petroleum byproduct, paraffin is inexpensive to produce
  • Versatile: Works well for container candles, pillars, tapers, and decorative shapes
  • Clean appearance: Produces smooth, glossy surfaces that look attractive

Considerations

  • Derived from non-renewable petroleum sources
  • Can produce more soot than some alternatives if the wick isn't properly maintained
  • Some people are sensitive to the fumes, though research on health impacts is mixed
  • Not suitable for those seeking plant-based or vegan products
💡 The Soot Myth

While paraffin is often criticised for producing soot, the truth is that any candle can produce soot if the wick is too long or the candle is in a drafty location. Properly maintained paraffin candles can burn quite cleanly.

Soy Wax: The Popular Natural Alternative

Soy wax emerged in the 1990s as a natural alternative to paraffin. Made from hydrogenated soybean oil, it quickly gained popularity among environmentally-conscious consumers and has become one of the most common wax types on the market.

Advantages of Soy Wax

  • Renewable and biodegradable: Made from soybeans, a sustainable crop
  • Longer burn time: Soy wax typically burns 25-50% longer than paraffin at comparable weights
  • Lower melting point: Creates a larger melt pool, which can improve fragrance distribution
  • Easy cleanup: Spilled soy wax can be cleaned with soap and water
  • Vegan-friendly: A plant-based option for those avoiding animal products
  • American-grown: Most soy wax comes from US soybeans, reducing transport emissions for North American markets

Considerations

  • Can have a weaker scent throw compared to paraffin, particularly hot throw
  • May develop "frosting" (white crystalline coating) which is cosmetic but harmless
  • Often requires additives or blending with other waxes for optimal performance
  • Environmental benefits depend on farming practices; conventional soy farming has its own impacts
  • May contain small amounts of paraffin or other additives in blends (check labels)

Beeswax: Nature's Premium Option

Beeswax is the oldest candle-making material, used for thousands of years before paraffin was discovered. It's a natural byproduct of honey production, created by bees to build their honeycomb structures.

Advantages of Beeswax

  • Completely natural: Requires no chemical processing, just filtering and melting
  • Air purifying claims: Some believe beeswax releases negative ions that clean the air, though scientific evidence is limited
  • Naturally scented: Has a subtle honey aroma even without added fragrances
  • Very long burn time: The highest density of common waxes, beeswax burns slowly
  • Dripless when properly made: High-quality beeswax candles drip minimally
  • Bright flame: Produces a warmer, brighter flame than most alternatives

Considerations

  • Expensive: Can cost 5-10 times more than paraffin
  • Not vegan: An animal product, unsuitable for strict vegans
  • Natural scent can interfere with added fragrances
  • Supply is limited by honey production
  • Quality varies significantly between suppliers

Spotting Pure Beeswax

Pure beeswax candles are typically golden or honey-coloured and have a subtle sweet smell. White beeswax has been bleached. Be wary of "beeswax blend" labels, which may contain mostly other waxes.

Coconut Wax: The New Contender

Coconut wax is a relative newcomer to the candle market, gaining popularity for its excellent performance and sustainability credentials. It's made from hydrogenated coconut oil and is often blended with other waxes.

Advantages of Coconut Wax

  • Excellent scent throw: Holds fragrance exceptionally well, rivalling paraffin
  • Clean burn: Produces minimal soot when properly made
  • Sustainable source: Coconuts are a renewable, high-yield crop
  • Slow, even burn: Long-lasting with consistent performance
  • Creamy appearance: Creates beautiful, smooth candle surfaces
  • Vegan and natural: Appeals to health and environmentally conscious consumers

Considerations

  • More expensive than soy or paraffin
  • Often blended with other waxes due to its very soft texture
  • Less widely available than established wax types
  • Environmental impact depends on sourcing practices

Palm Wax: Beautiful but Controversial

Palm wax creates stunningly crystalline patterns in finished candles, but its environmental impact has made it controversial.

Advantages

  • Creates unique feathered or crystalline visual effects
  • Burns cleanly with good scent throw
  • Harder wax that works well for pillars

Significant Concerns

  • Palm oil production is a major driver of rainforest destruction
  • Associated with habitat loss for endangered species
  • Even "sustainable" palm certifications are controversial
  • Many ethical consumers avoid palm products entirely
⚠ Environmental Consideration

If you choose palm wax, look for RSPO (Roundtable on Sustainable Palm Oil) certification, though be aware that this certification has critics. Many brands and consumers prefer to avoid palm products altogether.

Wax Blends: The Best of Multiple Worlds

Many modern candles use wax blends, combining two or more wax types to achieve optimal performance. Common combinations include:

  • Soy-coconut: Improves scent throw while maintaining natural appeal
  • Coconut-paraffin: Balances performance with lower cost
  • Soy-beeswax: Adds hardness and improves burn characteristics
  • Paraffin-soy: Reduces petroleum content while maintaining strong scent throw

Blends can offer advantages that pure waxes cannot achieve alone, but they also make it harder to make simple claims about "natural" or "clean" products. Always check ingredient lists if these factors are important to you.

Making Your Choice

The "best" wax type depends entirely on your priorities:

  • For maximum scent throw: Paraffin or coconut wax
  • For longest burn time: Beeswax or soy wax
  • For environmental concerns: Soy or coconut wax (avoiding palm)
  • For budget-conscious shopping: Paraffin or soy wax
  • For luxury and natural purity: Beeswax
  • For vegan preferences: Soy or coconut wax

Remember that wax type is just one factor in candle quality. Wick selection, fragrance quality, and manufacturing care also significantly impact how a candle performs. A well-made paraffin candle may outperform a poorly-made soy candle, and vice versa.
