Candle Wax Fragrance: Finding The Perfect Ounce Ratio

When making candles, it's important to get the right balance of fragrance oil to wax. The general rule is to use 1oz of fragrance oil per 1 pound of wax, but this will only give you a fragrance load of 6.2%. If you want a stronger scent, you can use a higher percentage of fragrance oil, but it's important not to exceed the maximum fragrance load for your wax, as this can negatively impact the structure of your candle. The maximum fragrance load will depend on the type of wax and fragrance oil you're using, as every fragrance oil and wax type has different levels of density.

How to calculate the maximum fragrance load

The maximum fragrance load of a candle is usually around 5-6%, but can go up to 10%. To calculate the maximum fragrance load, you need to divide the maximum fragrance load percentage by 100 to make it a decimal number. For example, 10% would be 10 ÷ 100 = .10. You then multiply this decimal number by the number of wax ounces you are using. So, if you are using 16 ounces of wax, you would multiply .10 by 16, which equals 1.6. This means that the maximum amount of fragrance oil you can add to 16 ounces of wax is 1.6 ounces.

It's important to note that the wax and fragrance load must be measured in terms of weight and not volume. This is because every fragrance oil and wax type has different levels of density. For example, if you were to measure out 1 fl oz of one type of fragrance oil, it would weigh less than 1 fl oz of a denser fragrance oil.

To make things simpler, you can also use the formula of 1oz of fragrance per 1 pound of wax. This will give you a fragrance load of around 6.2%.

However, keep in mind that just because the wax is able to hold a certain percentage of fragrance oil, doesn't mean that you need to use the full amount. In fact, exceeding the maximum fragrance load can negatively impact your candle structure. It's always best to test out different fragrance loads to find the perfect balance for your candles.

How to calculate the fragrance load percentage

To calculate the fragrance load percentage, you need to measure the wax and fragrance oil in terms of weight, not volume. This is because every fragrance oil and wax type has different levels of density. For example, 1 pound of one type of wax might give you 16 fl oz of liquid, but a denser wax could give you 18 fl oz of liquid. This means that 1 fl oz of one fragrance oil will weigh less than 1 fl oz of a denser fragrance oil.

To work out the maximum fragrance load percentage, divide the percentage by 100 to make it a decimal number. For example, 10% would be 10 ÷ 100 = .10. Then, multiply this decimal number by the number of wax ounces you are using. For example, if you're using 16 ounces of wax, you would do .10 x 16 = 1.6. This means that the maximum fragrance load for 16 ounces of wax is 1.6 ounces of fragrance oil.

If you want to add fragrance at a lower percentage, you can use the same formula. For example, if you want to add fragrance at 8%, you would multiply 340 * .08 = 27 grams. So, if you add 27 grams of fragrance to 340 grams of wax, you'll get three 4 oz candles with an 8% fragrance load.

As a general rule, it's recommended to use 1oz of fragrance per 1 pound of wax. However, it's important to note that this will only give you a fragrance load of around 5-6%. If you want a stronger fragrance, you can increase the percentage, but be careful not to exceed the maximum fragrance load for your wax, as this can negatively impact your candle structure.

How to measure fragrance oil and wax

When making candles, it's important to measure fragrance oil and wax accurately. Candle-making experts recommend measuring wax and fragrance load in terms of weight rather than volume for accuracy. This is because every fragrance oil and wax type has different levels of density. For example, one pound of wax could melt down to 16 fl oz of liquid, but a denser wax could produce 18 fl oz of liquid.

To calculate the amount of fragrance oil needed for your wax, you can use the following formula: divide the maximum fragrance load percentage by 100 to make it a decimal number, then multiply this by the number of wax ounces you are using. For example, if you have a maximum fragrance load of 10% and are using 16 ounces of wax, you would calculate 10/100 x 16, which equals 1.6. This means you can add a maximum of 1.6 ounces of fragrance oil to your wax.

It's important to note that just because the wax can hold a certain percentage of fragrance oil, it doesn't mean you need to use the full amount. However, exceeding the maximum fragrance load can negatively impact your candle structure. If you're unsure of the maximum fragrance load for your wax, it's safest to stay within the range of 5-6%.

When adding fragrance oil to your wax, it's recommended to start with a lower percentage and gradually increase until you achieve the desired scent. This is because fragrance oils can vary in strength, and you may need less oil than expected to achieve a strong scent. It's also important to consider the type of wax you're using, as some waxes can hold more fragrance oil than others. For example, soy wax can hold up to 10% fragrance oil, while paraffin wax can hold up to 12%.

By following these guidelines and calculations, you can ensure that your candles have the perfect balance of fragrance and wax, creating a pleasant and safe burning experience.

How to make test candles

To make test candles, you'll need to start by figuring out how much fragrance oil to add to your wax. Candle-making experts recommend measuring both the wax and fragrance load in terms of weight, not volume, as every fragrance oil and wax type has a different density.

To calculate the amount of fragrance oil to add, you need to know the maximum fragrance load percentage for your wax. If you can't find this information, it's recommended to stay within a range of 5-6%. For example, if you're using 1 pound of wax, which is equal to 16 net weight ounces, and your maximum fragrance load is 10%, you would divide this percentage by 100 to get a decimal number (0.10). Then, multiply this by the number of wax ounces (0.10 x 16 = 1.6), which gives you the maximum ounces of fragrance oil you can add.

Using this formula, you can determine that 1 ounce of fragrance oil per 1 pound of wax is approximately a 6.2% fragrance load. However, keep in mind that you don't have to use the full amount of fragrance oil that the wax can hold. As long as you don't exceed the maximum fragrance load percentage, you can add less fragrance oil if desired.

Now that you know how much fragrance oil to add, it's time to make your test candles! Melt down your wax and add the calculated amount of fragrance oil, stirring well to combine. Then, pour the scented wax into your chosen moulds and allow it to cool and harden. Remember, making test candles is a great way to experiment with different fragrances and find the perfect scent for your candles.

How to avoid negatively impacting candle structure

To avoid negatively impacting candle structure, it's important to understand the relationship between fragrance oil and wax. Candle-making experts emphasise that wax and fragrance load must be measured in terms of weight, not volume. This is because every fragrance oil and wax type has different levels of density. For example, one pound of wax can melt down to 16 fluid ounces of liquid, but a denser wax could yield 18 fluid ounces of liquid.

To determine the maximum fragrance load percentage, divide the percentage by 100 to make it a decimal number. For instance, if the maximum fragrance load is 10%, divide 10 by 100 to get 0.10. Next, multiply this decimal number by the number of wax ounces you are using. If you're using 16 ounces of wax, multiply 0.10 by 16 to get 1.6. This means you can add a maximum of 1.6 ounces of fragrance oil to 16 ounces of wax without negatively impacting the candle structure.

It's important to note that just because the wax can hold a certain percentage of fragrance oil doesn't mean the full amount is necessary. In fact, exceeding the maximum fragrance load can harm the candle structure. If you're unsure about the maximum fragrance load percentage for your wax, it's safest to stay within the range of 5-6%.

To ensure you're adding the correct amount of fragrance oil, make test candles with different fragrance loads. This will help you determine the optimal fragrance load for your specific wax and fragrance oil combination. By following these steps and staying within the recommended fragrance load percentages, you can avoid negatively impacting the structure of your candles.
