Creating Fragrant Soap: The Right Fragrance To Soap Ratio

When making soap, it's important to get the right balance of fragrance. Too much can disrupt the trace and saponification of the soap, but too little and the scent will be lost. The amount of fragrance you add is also a matter of personal preference. For solid soaps, it's recommended that you don't exceed 5% perfume, but you can add up to 8-10% depending on the fragrance you're using and your personal preference. For liquid soaps, the amount of fragrance is calculated based on the weight of the product.

The maximum amount of fragrance to add to soap is 0.7 oz PPO, but some say 0.85 oz

For solid soaps, Melt and Pour bases or cold or hot saponification, it is best not to exceed 5% perfume. However, fragrance oils are more concentrated, so 5% is a good amount to start with, but you can add up to 8% to 10% depending on personal preference.

The EU default is 3%, while the US maximum is 6-8%

The amount of fragrance you add to your soap base is a matter of personal preference, but there are some guidelines to follow. The EU default is 3%, while the US maximum is 6-8%. This means that for every 100g of soap base, you can add between 3 and 8g of fragrance.

For melt-and-pour soap bases, it is recommended to not exceed 5% perfume. This is because some fragrances can disrupt trace and saponification if used in excess.

When using essential oils, a good rule of thumb is to use 0.7 ounces per pound for cold process soap and 0.25 ounces per pound of melt-and-pour base.

To make the process easier, you can use a fragrance calculator. This will help you determine the exact amount of fragrance to add based on the weight of your soap base.

For solid soaps, the maximum fragrance is 5%

When using fragrance oils, 5% is a good amount to start with. However, you can add up to 8-10% depending on your preference. Essential oils have a more delicate fragrance, so you may want to add a little more to achieve the desired scent.

If you're making a large batch of soap, it's a good idea to measure out your fragrance into separate cups before mixing. This will ensure that your fragrance is evenly distributed throughout your soap.

It's also important to check the IFRA certificate to know the maximum dosage for each class of fragrance. This will ensure that you're using a safe amount of fragrance and won't disrupt the soap-making process.

For liquid soaps, calculate the weight of the perfume on the oils

When making soap, the amount of fragrance you add is a matter of personal preference. However, there are some guidelines you can follow. For solid soaps, it is best not to exceed 5% perfume. For liquid soaps, the weight of the perfume is calculated based on the weight of the oils.

To calculate the weight of the perfume for liquid soap, you need to know the weight of the oils you are using. Let's say you are using 3 cups of soap base, which is approximately 700 grams. If you want to add 5% perfume, you would calculate 5% of 700 grams, which is 35 grams. So, you would add 35 grams of perfume to your liquid soap base.

You can also use a fragrance calculator to help you determine the amount of fragrance to use. The Bramble Berry Fragrance Calculator, for example, suggests using 0.7 ounces of fragrance per pound of cold process soap, and 0.25 ounces per pound of melt and pour base.

It's important to note that some fragrances can disrupt trace and saponification if used in excess. The maximum amount of fragrance recommended for soap is typically between 0.7 and 0.85 ounces per pound. The default maximum usage rate in the EU is 3%, while most US soapers use around 6-8%.

When adding fragrance to your soap, it's best to start with a smaller amount and then add more if needed. You can always add more fragrance, but it's difficult to remove it if you've added too much.

You can use fragrance oils or essential oils

If you're using essential oils, you can add 0.7 ounces per pound for cold process soap, and 0.25 ounces per pound of melt and pour base. If you're using fragrance oils, these are more concentrated, so you can add less. For example, if you're making a 5-pound batch of cold process soap, you'll need 3.60 ounces of fragrance oil.

To add fragrance to your soap, measure out around 5 millilitres or 5 grams of fragrance oil or essential oil into a separate cup. Then, pour 4 ounces of soap base into the cup and stir well. Repeat this process for each fragrance you're using.
