How Much Essential Oil Should You Add to Your Candles?
Making scented candles is both an art and a science. One of the most common questions we get from candle makers—especially beginners—is:
“How much essential oil should I add to my candles?”
The answer depends on several factors, including the type of wax, the strength of fragrance you want, and the specific essential oil you’re using. Here’s a quick guide to help you get the perfect scent throw while ensuring a clean, even burn.
Recommended Essential Oil Ratio for Candles
A good starting point is 5% to 8% of the total wax weight. For example:
If you’re using 100g of wax, add 5g to 8g (approx. 5-8ml) of essential oil.
Adjust Based On:
✔ Wax Type – Soy wax holds fragrance well (6-10%), while paraffin wax works best at 5-8%.
✔ Oil Strength – Light citrus oils may need a slightly higher %, while strong oils like patchouli or cedarwood require less.
✔ Desired Scent Throw – For a subtle aroma, use 5-6%. For a stronger throw, go up to 8-10%.
Pro Tip: Always check your supplier’s recommendations, as some oils are more concentrated than others.
Why Proper Oil Ratio Matters
Too little oil? Your candle won’t have a noticeable scent.
Too much oil? It can cause poor burning, soot, or even fragrance oil seeping out.
For best results, test small batches first before making large quantities.
