How much essential oil do you put in a candle?

Essential oils are aromatic compounds extracted from plants that are used to provide fragrance and therapeutic benefits. When adding essential oils to candles, the goal is to create a candle with a nice even scent without the oils overpowering the wax. Determining how much essential oil to use in candle making takes some experimentation based on the size of your container, the type of wax, and the strength of the essential oil. Here are some tips for using essential oils in candles.

Factors That Determine Essential Oil Amount

There are a few key factors that determine how much essential oil you should use when making scented candles:

  • Container size – The amount of wax (and therefore essential oil) needed will vary depending on the size of your candle container. More oil is needed for larger containers.
  • Wax type – The wax composition impacts how well it retains fragrance. Natural waxes like soy and beeswax hold scents better than paraffin.
  • Essential oil strength – How concentrated the aroma is depends on the plant source. Thick, resinous oils like sandalwood are stronger than light citrus oils.
  • Fragrance preference – Personal choice on scent strength also factors in. Some prefer subtle scents while others like very aromatic candles.

Testing out different oil amounts is the best way to determine your ideal concentration. A starting point is around 1% of the wax weight, though many variables can affect the final outcome.

General Essential Oil Use Rates

As a general guideline, here are typical essential oil usage rates:

  • 1-3% for lighter oils like citrus, herbals, and florals
  • 3-6% for woodsy, earthy, and spice oils
  • 5-10% for very strong oils like clove, rosemary, and patchouli

The recipes below provide more specific amounts based on various candle sizes.

Essential Oil Amounts for Small Candles

For small candles like votives and tarts that hold 1-4 ounces of wax, a good starting amount is:

  • 15-30 drops for lighter essential oils
  • 25-45 drops for medium strength oils
  • 30-60 drops for very strong oils

Always add oils gradually and test the scent throw along the way. For votives and tarts, stir the oil into melted wax before pouring into molds.

  • Start with less oil – it’s easy to add more, hard to remove excess.
  • Mix well and allow candle to cure 1-2 hours for scent to develop.
  • Consider blending oils for more complex aromas.
  • Use toothpicks for drop-by-drop precision.
  • Store unused oils properly in dark glass bottles.

Frequently Asked Questions

Does wax type affect how much essential oil to use?

Yes, the wax composition makes a big difference in how much essential oil it can hold. Natural waxes like soy, coconut, and beeswax have a higher oil capacity compared to paraffin. A 16 ounce soy candle would need about 2 teaspoons of oil versus 1 teaspoon for a paraffin candle of the same size.

Can I use more essential oil to make candles extra fragrant?

It’s generally not recommended to use more than 10% essential oils in candles. Excessive amounts can cause the wax to sweat oil pools on the surface. Too much oil can also lead to smoking, tunneling, and an uneven burn.

How do I know which essential oils are stronger?

As a general rule, thick resinous oils from wood, seeds, roots, and spices are very concentrated. These include sandalwood, clove, patchouli, vetiver, cedarwood. Citrus and floral oils tend to be lighter and require more volume.

Is there a difference between scented oils and essential oils?

Scented oils are synthetic fragrance oils, while essential oils come directly from real plant sources. For a natural homemade candle, stick with pure essential oils. Be sure they are not adulterated or diluted with carriers.

Should I add essential oils to the wax while hot or cold?

Always add the essential oils once the wax has fully liquefied to ensure proper incorporating throughout the candle. Cooler wax can hold less oil saturation.
