Scent is perhaps the most compelling aspect of handmade candles and soap. It's what draws you to a certain bar of handcrafted soap at a craft show or farmer's market. And it is the best way to make your own handmade soap a unique gift that'll be remembered.

If you want to try your "nose" at creating your own blends of essential or fragrance oils for your soaps and candles, it's not hard. Whether you're an experienced aromatherapist or new to scent blending, you can create your own complex scent blends that will make your soaps and candles smell wonderful with a scent that is uniquely yours. Grab a notebook and let's get started as this process can take anywhere from a few minutes to a couple of days.

What You'll Need


  • Assortment of essential or fragrance oils
  • Small jars with airtight lids (such as jelly jars)
  • At least one clean cotton swab for each scent oil in the blend
  • A notebook to record your results


Many people start by blending essential oils since they are basic components used to build more complex blends. But you can try any combination of essential or fragrance oils.

As you examine individual components, make notes on how long-lasting the scent is. This will determine if it is a top note (the first, fleeting scent you smell in a fragrance), middle note (the scent you notice after a while; it lingers a little longer), or base note (the longest-lasting scent in a blend that takes the longest to "come to the top"). Ideally, the final blend will include one of each note at least. Alternatively, you can just choose several oils that you think will go well together. This is all about experimentation.

  1. Open Containers

    Open the oils and the small glass jar. You may be able to get a preview of your scent blends merely by having the three bottles open at the same time.

  2. Dip Cotton Swab in Oil

    One at a time, dip the tip of a clean cotton swab into the fragrance or essential oil. Squeeze any excess oil from the swab on the lip of the bottle. Instead of cotton swabs, you can use an eyedropper or disposable pipette and a paper towel, but make sure you use a fresh dropper or pipette for each essential oil.

  3. Put Swab in Jar

    Place the swab in the glass jar.

  4. Repeat for Each Scent

    Repeat for each of the scents you want to add to the blend.


    Try to get equal amounts of fragrance or essential oil on each cotton swab, and make sure they are completely clean, or else you'll risk contaminating your essential oils.

  5. Keep Notes on Oil Testing

    Make sure to write down each oil you include in the blend.

  6. Walk Away

    Walk away from the jar and wait a few minutes.

  7. Smell Scent Blend

    Come back to the jar and gently sniff the air above the jar. Don't stick your nose into the jar to smell the blend. Let the scent rise from out of the jar. This will be the scent blend in its early stage of development. Take notes on your thoughts about it. Is one oil overpowering the others? Do two of them seem too similar to tell apart?

  8. Let Jar 'Mature' and Smell Again

    Put the lid on the jar and leave it in a cool, dark place. After a few hours, open the jar and smell the blend again. The scent should have mixed further and "matured" a bit. Take further notes on your thoughts about the blend.

  9. Repeat Previous Step

    Place the lid back on the jar and return it to the cool, dark place. Wait about 48 hours until the scent blend has fully mixed and "matured." Take more notes about the blend.

  10. Make Corrections to Blend

    Make corrections to your blend. Perhaps try two parts of oil A and one part of oil B. Or add some oil D to your blend of A, B, and C. Try the blend again until you find the perfect combination.


    Sniffing coffee beans or ground coffee will cleanse your scent receptors (just like cleansing your palate). Sniff some coffee beans in between tests and you'll get a more accurate reading of the scents.

  11. Test Scent Blend in Candle or Soap

    Once you are confident in your scent blend, try using it in a candle or soap. Take notes on how it works in them so you know what you need to change for next time.
