The Complete Guide to Fragrance Oils for Candles

Fragrance oils are what transform a simple candle into an aromatic experience that can evoke memories, create ambiance, and fill your home with delightful scents. Understanding how to select, use, and maximize fragrance oils is crucial for creating candles with exceptional scent throw.

Understanding Fragrance Oils

What Are Fragrance Oils?

Fragrance oils are synthetic or blended aromatic compounds specifically designed for candle making. Unlike essential oils, they're formulated to withstand the high temperatures of melted wax and provide consistent, strong scent throw.

Fragrance Oil vs Essential Oil

Fragrance Oils:

• Synthetic or blended compounds
• Designed for candle making
• Stronger scent throw
• More stable at high temperatures
• Wider variety of scents
• More affordable

Essential Oils:

• Natural plant extracts
• Not always candle-safe
• Often weaker scent throw
• Can be affected by heat
• Limited scent options
• Generally more expensive

Types of Fragrance Oils

Single Note Fragrances

These feature one dominant scent:

• Vanilla
• Lavender
• Ocean Breeze
• Apple Cinnamon
• Fresh Linen

Complex Blends

Multi-layered fragrances with top, middle, and base notes:

• Top notes: First impression (citrus, herbs)
• Middle notes: Heart of the fragrance (florals, fruits)
• Base notes: Lasting foundation (woods, musks, vanilla)

Seasonal Categories

Spring/Summer:

• Fresh and clean (Ocean breeze, Fresh linen)
• Floral (Rose, Jasmine, Lilac)
• Fruity (Citrus, Berry blends)

Fall/Winter:

• Warm and cozy (Vanilla, Cinnamon)
• Woodsy (Sandalwood, Cedar)
• Spicy (Pumpkin spice, Clove)

Fragrance Load Guidelines

Recommended Percentages by Wax Type

Soy Wax: 8-10%

• Conservative: 6-8%
• Standard: 8-10%
• Maximum: 12% (rarely recommended)

Paraffin Wax: 10-12%

• Standard: 10-11%
• Maximum: 12-15%

Coconut Wax: 12-15%

• Can handle higher fragrance loads
• Excellent scent throw

Beeswax: 3-6%

• Lower loads due to natural honey scent
• Higher loads can cause poor burning

Calculating Fragrance Amounts

Formula: Wax weight × fragrance percentage = fragrance oil needed

Example:

• 500g soy wax × 0.08 (8%) = 40g fragrance oil
• 1 lb paraffin wax × 0.10 (10%) = 1.6 oz fragrance oil

Maximizing Scent Throw

Hot Throw vs Cold Throw

Cold Throw: Scent when candle is not burning Hot Throw: Scent when candle is burning

Tips for Better Scent Throw

1. Temperature Control:

   • Add fragrance at the right temperature (usually 185°F/85°C)
   • Pour at optimal temperature (135°F/57°C)

2. Proper Mixing:

   • Stir gently for 2 full minutes
   • Avoid creating bubbles

3. Curing Time:

   • Allow 24-48 hours minimum
   • Some fragrances improve over several weeks

4. Wick Selection:

   • Proper wick size creates optimal melt pool
   • Full melt pool = better scent throw
