How Much Fragrance Oil to Add to Candles: Beginner Guide

One of the most common questions beginner candle makers ask is:

How much fragrance oil should be added to a candle so it smells good?

It may seem simple: the more fragrance you add, the stronger the scent. But in practice, it doesn’t work that way.

Too little fragrance oil will make the candle almost scentless. Too much can cause poor burning, sweating, oily spots, and even reduced scent throw.

In this guide, we will understand the optimal fragrance percentage, how to calculate it correctly, and why more is not always better.

Why Is the Amount of Fragrance So Important?

When making scented candles, you must maintain a balance between wax and fragrance oil.

If there is too little fragrance oil:

• The scent will be barely noticeable
• The candle will not perform well when burning
• The customer may be disappointed

If there is too much fragrance oil:

• The wax may not hold the fragrance
• Oily spots may appear on the surface
• The wick may become unstable
• The candle may smoke or overheat

That is why wax manufacturers always recommend a maximum fragrance load.

What Is the Optimal Fragrance Percentage?

For most modern soy and coconut waxes, the ideal range is:

8–12% fragrance oil of the wax weight

This range provides a balance between safe burning and strong scent throw.

Recommended starting points:

• 8% – light fragrances
• 10% – universal option
• 12% – strong and rich compositions

How to Calculate Fragrance Oil Amount?

Formula: Wax weight × fragrance percentage

Example:

If you use 150g of wax and want 10% fragrance:

150 × 10% = 15g fragrance oil

You will need:

• 150g wax
• 15g fragrance oil

Why Not Use the Maximum Amount Immediately?

Many beginners assume that 15–20% fragrance will make candles smell stronger.

In reality, the opposite often happens.

Each wax has a fragrance load limit. When exceeded, excess oil separates from the wax.

Result:

• Oily candle surface
• Unstable burning
• Weaker hot scent throw
• Wasted materials

This is why professional candle makers always test before launching a new recipe.

When to Add Fragrance Oil?

The temperature is very important.

For most soy and coconut waxes:

60–65°C

At this temperature, fragrance binds best with wax.

After adding fragrance, mix gently for 1–2 minutes.

Why Candle Scent Does Not Appear Immediately?

After pouring, many makers test candles too early.

Most natural waxes need time to fully bind fragrance.

Curing time:

• Soy wax: 7–14 days
• Coconut wax: 7–14 days
• Some blends improve after 2–3 weeks
