What You'll Learn
Calculating fragrance load
Calculating the fragrance load is an essential step in candle-making. It ensures your product smells amazing without causing performance issues. The fragrance load is the percentage of fragrance oil in your candle compared to the total weight of your candle.
To calculate the fragrance load, you must first decide on your fragrance load percentage. This typically ranges from 6-10% for soy wax. For example, if you want to use an 8% fragrance load, this is your fragrance load percentage.
Next, determine the total weight of your candle. This includes the weight of the wax and the fragrance oil. For instance, if you're making a 16 oz candle, 16 oz is your total weight.
Now, calculate the amount of fragrance oil needed. Multiply the total weight of your candle by your fragrance load percentage (converted to a decimal). So, for a 16 oz candle with an 8% fragrance load, you'll need 1.28 oz of fragrance oil and 14.72 oz of wax.
It's important to note that the fragrance load can vary depending on the type of wax used. For example, paraffin wax typically has a lower scent capacity of around 3%, while pre-blended waxes or those with additives can hold higher fragrance loads of up to 12%.
You can also use a fragrance load calculator to determine the perfect amount of fragrance oil for your candle. These calculators take into account the size of your candle, the desired fragrance load percentage, and the type of wax used to provide the exact amounts of wax and fragrance oil needed.
By understanding and properly calculating the fragrance load, you can create candles that not only smell wonderful but also burn correctly, look great, and are safe to use.

Common fragrance load percentages
The fragrance load is the maximum amount of fragrance oil a particular wax can hold, expressed as a percentage of the total wax weight. It is an important factor in candle-making, as it determines the scent's intensity, influences the burning characteristics, and impacts the overall user experience.
For soy wax, a commonly recommended fragrance load percentage ranges from 6% to 10%. An 8% fragrance load is often suggested as a safe middle ground, helping to keep the wick from clogging and avoiding poor performance. However, it's important to note that the fragrance load may need to be adjusted based on temperature and humidity variations.
When determining the fragrance load, it is crucial to follow the manufacturer's guidelines for the specific wax being used. Exceeding the recommended fragrance load can lead to issues such as poor burn quality, safety concerns, or "sweating," where excess oil seeps out of the wax.

How to avoid issues with fragrance load
To avoid issues with fragrance load, it is important to understand the concept of fragrance load and the factors that influence it.
Understanding Fragrance Load
Fragrance load refers to the maximum percentage of fragrance oil that can be added to candle wax. It is calculated as a percentage of the total wax weight. For example, a 7% fragrance load means 7 grams of fragrance oil for every 100 grams of wax. This ratio ensures that the candle smells pleasant without being overwhelming and performs well.
Factors Influencing Fragrance Load
- Wax Type: Different types of wax have varying fragrance load capacities. For instance, paraffin wax typically has a lower scent capacity of around 3%, while pre-blended waxes or those with additives can hold higher fragrance loads, sometimes up to 12%.
- Additives: The use of additives can impact fragrance load. They may affect the rate of formation of the melt pool and the candle's tendency to produce soot. Therefore, it is important to research the compatibility and interactions of additives with other candle components before use.
- Wick Choice: Different wicks have different burning characteristics and will influence the rate of melt pool creation and the desired fragrance load.
- Fragrance Characteristics: Some fragrances have stronger hot throws than others. Understanding the desired fragrance throw for each scent is crucial in determining the appropriate fragrance load.
- Temperature and Humidity: Fragrance load may need to be adjusted based on changes in temperature and humidity. Natural waxes, in particular, are sensitive to temperature variations during pouring and storage.
Best Practices
- Accurate Measurement and Calculation: Utilize tools such as a digital scale, measuring cups, syringes, and a calculator to ensure precise measurements and calculations.
- Testing and Adjusting: Conduct test burns to evaluate the scent throw and burn characteristics. If adjustments are needed, modify the fragrance load or consider a different wax type.
- High-Quality Fragrance Oils: Ensure the use of high-quality, candle-safe fragrance oils.
- Experimentation: Fragrance load calculation often involves trial and error. Be prepared to experiment with different fragrances and loads to find the perfect balance for your candle.
- Online Resources: Take advantage of online fragrance load calculators and guides to assist in determining the correct fragrance load for your specific candle-making needs.
By following these guidelines and gaining a comprehensive understanding of fragrance load, candle makers can create high-quality products with desirable scent throws and optimal burn qualities.

How to test fragrance load
Testing fragrance load involves testing the strength of a scent. This is particularly important when making candles, as fragrance load refers to the percentage of fragrance oil in relation to the total weight of wax used.
To test fragrance load, you can use a fragrance load calculator. This will require you to input the amount of fragrance oil you plan to use, measured in ounces. The calculator will then display the fragrance load percentage. This will help you adjust your recipe as needed.
When testing fragrance load, it is important to consider the following:
- Each wax type has a unique maximum fragrance load capacity, so always check manufacturer recommendations.
- Test small batches: Experiment with different percentages to find the ideal fragrance load for your desired scent strength.
- Weigh accurately: Use a digital scale for precise measurements of wax and fragrance oil.
- Consider the environment: Higher fragrance loads may perform differently in hot or humid climates.
In addition to using a calculator, you can also test fragrance load by following your sense of smell. Here are some tips for testing fragrances:
- Start with blotters or paper strips: These are the white cardboard strips you find near fragrance display bottles. They allow you to narrow down a few favourites before testing on the skin.
- Test on your skin: Spray your wrist or the back of your hand with the fragrance. Two spritzes should be enough. Drop your hand to your side and wait at least 30 seconds for the scent to settle on your skin. Once it has started to dry, bring your hand up and inhale without touching your nose to the skin.
- Take your time: The fragrance will deepen as you experience each of the levels of notes in its formulation. It will also react with the warmth of your skin, your skin's natural oils, and your body chemistry to create a unique scent.
- Avoid wearing other fragrances when testing a new one.
- Use olfactory palate cleansers, such as coffee beans, between fragrances to reset your sense of smell.
