Weighing fragrance oils is an important step in candle-making to ensure a consistent scent throughout. The weight of fragrance oil is based on its percentage in the wax, typically around 6% or 1 ounce per pound of wax, with a maximum of 10% or 1.6 ounces per pound. To weigh fragrance oil, a sensitive high-accuracy digital scale is required, as different oils can vary in volume. The weight of the wax is first determined, and then the desired percentage of fragrance is calculated by multiplying the weight of the wax by the fragrance load. This weight is then measured out on the scale and added to the wax at the recommended temperature of 185*F.

What You'll Learn
Use a scale, not measuring spoons or cups
When preparing fragrance oil, it is imperative to use a scale instead of measuring spoons or cups. This is because different fragrance oils can vary in volume or density, so using measuring spoons or cups can lead to inaccurate measurements. For example, the same volume of two different fragrance oils may result in very different weights, which can affect the overall weight of your final product.
Additionally, using a scale ensures accuracy and consistency in your measurements. Weighing your fragrance oil allows you to calculate the exact percentage of fragrance load in your product, which is crucial for achieving the desired scent strength and ensuring a consistent fragrance throughout your product line. Whether you're measuring in ounces or grams, weight is the most reliable way to measure fragrance oil.
Another reason to avoid measuring spoons or cups is to prevent potential chemical reactions. Fragrance oils can react with certain materials, such as plastic, causing the plastic to break down. Therefore, it is recommended to use glass containers or wax-lined paper cups for measuring fragrance oil. These materials are less likely to react with the oil and can be easily disposed of, ensuring a clean and safe workspace.
Lastly, using a scale allows for easy adjustments to your fragrance oil measurements. If you need to increase or decrease the amount of fragrance oil in your product, you can simply adjust the weight measurement accordingly. This flexibility is especially important when working with different types of wax, as each wax type has a maximum fragrance load that should not be exceeded. By weighing your fragrance oil, you can ensure that you stay within the safe limits and create a high-quality product.

Use a glass container
When weighing fragrance oil, it is important to use a glass container. This is because fragrance oil can react with some materials, such as plastic, and cause the container to break down. Using a glass container ensures that the oil can be measured accurately and safely.
- Choose a glass container that is clean and dry. It should be small enough to fit on your scale comfortably.
- Place the glass container on the scale and tare it. This will zero out the weight of the container so that you are only measuring the weight of the fragrance oil.
- Pour the fragrance oil into the glass container. Be careful not to spill, as fragrance oil can be difficult to clean up.
- Use a sensitive, high-accuracy digital scale to measure the weight of the fragrance oil. Candle and soap scales are ideal for this purpose.
- Read the weight measurement from the scale. If you are using a percentage to calculate the amount of fragrance oil needed, multiply the weight of your wax by the percentage of fragrance oil you want to use. For example, if you are using 16 oz of wax and want to add 6% fragrance oil, you would multiply 16 by 0.06 to get 0.96, which can be rounded up to 1 oz.
- Once you have measured the desired amount of fragrance oil, carefully pour it into your wax. Stir gently and thoroughly to ensure consistent distribution.
By following these steps and using a glass container, you can accurately and safely weigh fragrance oil for your candles or other scented products.

Use percentages for consistent results
When making candles, it's important to weigh out your fragrance oils to ensure a consistent scent throughout. Using percentages is a good way to guarantee consistent results. The maximum fragrance load depends on the type of wax you are using, and this can usually be found on the product page under the properties section. Most waxes have a maximum fragrance load of around 10%, with the typical amount being about 6%.
The first step is to measure the weight of the wax you will be using. You can do this by weighing the wax you'll need for all the candles being poured in that batch. Make sure you know the weight in ounces or grams, not fluid ounces, as this is for volume.
Once you have the weight of your wax, you can calculate the weight of fragrance oil to add. This is done by multiplying the weight of the wax by the percentage of fragrance load you want to achieve. For example, if you are using 16 oz of wax and want to add 6% fragrance oil, you would multiply 16 x 6% (or 0.06) to get 0.96, which can be rounded up to 1 oz.
If you are making a large batch of candles, you can calculate the fragrance oil weight by multiplying the total weight of wax by the percentage of fragrance. For example, if you are making 8 candles, each using 8 oz of wax, you would first calculate the total weight of wax by multiplying 8 x 8 to get 64 oz. If you want to add 6% fragrance oil, you would then multiply 64 x 6% (or 0.06) to get 3.84, which can be rounded up to 4 oz of fragrance oil.
Using percentages allows you to easily adjust the amount of fragrance oil depending on your desired fragrance load and the number of candles you are making. It also ensures that you do not exceed the maximum fragrance load for your wax, which can affect the performance and aesthetics of your candles.

Use a high-accuracy digital scale
When preparing to weigh fragrance oil, it is important to have a sensitive high-accuracy digital scale. This is imperative to accurately measure out the oils. You want to have a minimum of 6% fragrance oil and generally not exceed 12% for most waxes. The maximum fragrance load depends on the wax, but it is usually safe to assume 5%–6% if it is not listed or cannot be found.
The first step is to measure the wax needed for all the candles being poured in a batch. This should be done in weight, in ounces or grams, and not fluid ounces, which are for volume. The weight of the wax will be used to calculate the fragrance oil weight.
The formula to calculate the fragrance oil weight is to multiply the weight of the wax by the fragrance load (percentage). For example, if you are making 8 candles, each using 250g of wax with 7% fragrance, you would multiply 250 x 7% (or 0.07), which equals 17.5g of fragrance oil. If you are making a large batch of wax, take the entire amount and multiply it by the per cent of fragrance you are adding. For example, if you are making 8 candles of 8 ounces each, you would multiply 8 x 8 = 64 oz of wax, then 64 x 6% (or 0.06) = 3.84, which can be rounded up to 4 ounces of fragrance oil for 64 ounces of wax.
It is important to note that different oils can vary in volume, so it is always best to weigh fragrance oil with a scale rather than measuring it with a spoon or cup. Additionally, fragrance oil can react with some containers, so it is recommended to use a glass container or a wax-lined paper cup, as they are disposable, and clean-up is quick and easy.

Multiply wax weight by fragrance load to find oil weight
When making candles, it's important to weigh out your fragrance oils accurately to ensure a consistent scent throughout. The first step is to determine the fragrance load, which can range from 3% to 12% by weight. Most waxes have a 10% maximum fragrance load, but this can vary, so it's important to check the product page for the specific wax you're using.
Once you know the fragrance load, you can calculate the fragrance oil weight by multiplying the wax weight by the fragrance load. For example, if you're making 10 candles and each needs 250g of wax with a fragrance load of 7%, you would multiply 250 by 0.07 to get 17.5g of fragrance oil needed for each candle. This calculation ensures you don't add too much fragrance oil, which can lead to issues like tunnelling, poor scent throw, and wicks not staying lit.
Using percentages or a fragrance load as a decimal ensures consistent results. For example, if you're working with 16 ounces of wax and adding 6% fragrance oil, you would multiply 16 by 0.06 to get 0.96, which you can round up to 1 ounce. This calculation method is straightforward and guarantees consistent results.
It's important to use a sensitive, high-accuracy digital scale to weigh your fragrance oils. Additionally, fragrance oil can react with certain containers, so avoid letting it sit in a paper cup for too long and never use plastic containers. Always refer to the specific gravity or density of the fragrance oil, which is typically around 0.86, to make accurate calculations.
