Soy Wax Fragrance Ratios: Finding The Perfect Scent Balance

When making scented candles, it's important to get the ratio of fragrance oil to wax right. Too much fragrance oil can ruin the composition of the candle and cause it to not set properly, while too little will result in a faint scent. The general rule of thumb is to use 1 oz of fragrance oil for every 1 pound of soy wax, which is around 6-7% fragrance load. However, soy wax can contain up to 10% fragrance load, but this may cause wicking issues. It's important to measure the fragrance load by weight and not volume, as every fragrance oil and wax type have different levels of density.

The standard ratio is 1 oz of fragrance oil to 1 pound of soy wax

When making scented candles, it's important to get the right balance of fragrance oil to soy wax. The standard ratio is 1 oz of fragrance oil to 1 pound of soy wax. This is the most common rule of thumb and will give you a 6.25% fragrance load.

To calculate this, you divide 1 oz of fragrance oil by 16 oz (1 pound) of soy wax. This will ensure your candle has a good scent without impacting the flame's ability to burn through the oil or causing disturbances to the top of the candle.

It's worth noting that soy wax can contain up to 10% of the fragrance load, but going above 7% will make it harder to wick and could cause issues with the structure of your candle. So, while more doesn't necessarily mean better when it comes to fragrance oil, it's important to find the perfect ratio so your composition isn't ruined and the scent doesn't fall flat.

If you're making a large batch of candles, you will base all your measurements on the total amount of wax you have by weight and add fragrance by weight. It's also important to only add your fragrance when your wax temperature is below the flashpoint of the fragrance, which is generally between 50-55 degrees Celsius. The flashpoint is the temperature at which the fragrance becomes volatile and may catch alight.

This is 6.25% fragrance load

When making candles, the amount of fragrance you use can make or break your candle. The fragrance load is the percentage of fragrance you mix into your jar along with your candle wax. It is always expressed as a percentage.

The most common rule of thumb for fragrance oils in soy wax is 1 oz of fragrance oil to 1 pound (16 oz) of wax. This equates to a fragrance load of 6.25%. This is calculated by dividing 1 (oz of fragrance oil) by 16 (lbs of wax) to get 0.0625, or 6.25% when expressed as a percentage.

Soy wax can contain up to 10% fragrance load, but this may cause wicking issues. If you are using a container, you can calculate the amount of fragrance oil needed based on the amount of wax the container can hold. For example, if your container can hold 3 pounds of melted soy wax, you would need to use 3 oz of fragrance oil for a 6.25% fragrance load.

It is important to note that not all fragrance oils are created equal. Some scents are heavier than others and require less fragrance. For example, fragrances with vanilla, sandalwood, oudh, or caramel can be reduced to a 6% fragrance load without impacting the scent throw.

Additionally, the type of wax you are using will also affect the amount of fragrance oil needed. The wax manufacturer should provide a maximum fragrance oil load percentage, which is usually based on weight. This tells you the maximum amount of fragrance oil the wax can hold successfully. However, it is not necessary to use the full amount, and exceeding this amount can negatively impact your candle structure. If you are unable to find the maximum fragrance load percentage, it is generally safe to stay within the range of 5-6%.

Finally, it is important to measure your fragrance load by weight instead of volume. Candle-making experts recommend using weight because every fragrance oil and wax type has different levels of density. By using weight, you can ensure that your candle recipe is precise.

A higher fragrance load can cause wicking issues

Adding fragrance oil to soy wax is a delicate process that requires precision to avoid issues with the candle's appearance and functionality. While the general rule of thumb is to use 1 oz of fragrance oil for every pound of soy wax, which equates to a 6.25% fragrance load, the wax can technically hold up to 10% fragrance load. However, going beyond 7% fragrance load will likely result in wicking issues.

Wicking issues refer to problems with the candle's wick, which is responsible for drawing up the melted wax to fuel the flame. When there is too much fragrance oil in the wax, it can saturate the wick, causing it to become clogged. This, in turn, leads to a range of problems, including:

• Flickering or unstable flame: An oversaturated wick can cause the flame to flicker or become unstable due to the excess oil impeding the flow of wax.
• Excessive soot: The clogged wick can produce more soot than usual, which not only discolours the candle but also releases particles that can be harmful to breathe.
• Drowning wick: In some cases, the excess oil may cause the wick to become completely drowned, resulting in a candle that struggles to stay lit.
• Poor scent throw: Despite using a higher amount of fragrance oil, the candle may exhibit a weaker scent throw due to the impaired burning process.
• Increased flammability: Fragrance oils are highly flammable. Therefore, an oversaturated wick can act as a fuel source, increasing the risk of flare-ups or flashovers, which are sudden and uncontrolled ignitions.

To avoid wicking issues and the associated problems, it is crucial to maintain the recommended fragrance load of no more than 7%. This ensures the candle burns safely and effectively, providing the best experience for the user.

The maximum fragrance load is 10%

When making scented candles, it's important to get the ratio of fragrance oil to wax just right. While you might think that adding more fragrance oil will result in a stronger scent, this is not always the case. In fact, adding too much fragrance oil can negatively impact your candle's structure and cause issues with the wicking.

The general rule of thumb is that you need 1 oz of fragrance oil for every 1 pound of soy wax. This equates to 6.25% fragrance load. However, soy wax can technically hold up to 10% fragrance load. To calculate this, you divide 1 oz of fragrance oil by 16 oz of soy wax, which gives you 0.0625, or 6.25% fragrance load.

If you want to increase the fragrance load to 10%, you can do so by multiplying the number of pounds of wax by 0.10. For example, if you have 3 pounds of soy wax, you would multiply 3 by 0.10, which gives you 0.3. This means you would need to add 0.3 oz of fragrance oil to your 3 pounds of soy wax to achieve a 10% fragrance load.

It's important to note that while soy wax can hold up to 10% fragrance load, it may be difficult to work with and you may experience more wicking issues. Therefore, it is recommended to stay within the range of 6-8% fragrance load to ensure a good scent throw without impacting the burnability of the candle.

Additionally, the type of fragrance oil you use can also affect the fragrance load. Some fragrance oils, such as those with high-quality and concentration levels, may only require a usage of 6-8%. It's always best to refer to the manufacturer's recommendations for the specific fragrance oil you are using.

The amount of fragrance oil depends on the type of wax and fragrance

The amount of fragrance oil you add to your wax depends on the type of wax and fragrance you're working with. Getting the right ratio is important so that your candle's composition isn't ruined and the scent doesn't fall flat.

The wax manufacturer will provide a maximum fragrance oil load percentage, which is usually based on weight. This tells you the maximum amount of fragrance oil the wax can hold. However, you don't have to use this amount, and it's not recommended to exceed it as it could negatively impact your candle. If you can't find the manufacturer's guidance, it's best to stay within a range of 5-6%.

For example, if you're using 1 pound of wax (16 net weight ounces) and the maximum fragrance load is 10%, you would divide the maximum fragrance load percentage by 100 to make it a decimal number (10 divided by 100 = 0.10). Then, multiply the decimal number by the number of wax ounces you are using (0.10 x 16 = 1.6). This tells you that 1.6 ounces is the maximum amount of fragrance oil you can add to 16 ounces/1 pound of wax.

It's important to note that not all fragrance oils are created equal. Some are more potent than others, so you may need to adjust the amount you use accordingly. For example, fragrances with vanilla, sandalwood, oudh, or caramel can be reduced to a 6% fragrance load without affecting the scent throw.

Additionally, the type of wax you're using will also impact the amount of fragrance oil you need. Soy wax, for instance, typically calls for a fragrance load of 6.25% to 7% per pound of wax, but it can contain up to 10%. However, going above 7% may cause wicking issues.
