The Intricacies Of Fragrance Oils In Soap Making

Fragrance oils are a mix of natural ingredients and artificial aroma chemicals. They are synthetic fragrances created in a laboratory and are often used to scent soaps. Fragrance oils are typically created with a mix of aroma chemicals, essential oils, extracts, resins, and other natural raw materials. They can contain dozens of different ingredients to create complex and layered scents. While fragrance oils are a popular choice for soap-making due to their wide range of scent options, longevity, and reliability, they may not appeal to everyone as they are artificial. On the other hand, essential oils are natural extracts derived from plants, herbs, flowers, and trees through steam distillation. They offer potential therapeutic benefits and are generally considered ideal for those seeking natural ingredients in their soaps. However, essential oils tend to be more expensive and have limited fragrance options. Ultimately, the choice between using fragrance oils or essential oils in soap-making depends on personal preferences, desired outcomes, and cost considerations.

Are fragrance oils safe for soap-making?

Fragrance oils are generally safe to use in soap-making, but there are a few things to keep in mind. Fragrance oils are synthetic products, created with a mix of aroma chemicals and natural ingredients like essential oils, extracts, and resins. They are subject to stringent testing for use in cosmetics and are therefore considered safe to use. However, it's important to check that the fragrance oil you are using is suitable for soap-making, especially if you are using the cold process method.

One thing to consider when using fragrance oils in soap-making is that they can sometimes behave unpredictably. For example, some fragrance oils can cause the soap to accelerate, heat up, or discolour. This can be mitigated by researching ingredients beforehand and making a small test batch to see how the fragrance oil performs. It's also important to follow the recommended usage rates for soaps, which can be found on the product page for each fragrance oil or in the IFRA (International Fragrance Association) Certificate.

Another thing to keep in mind is that fragrance oils may not be suitable for everyone, as some people may have allergies or sensitivities to certain ingredients. It's always a good idea to read the descriptions and performance notes on the fragrance oil before use, and to disclose all ingredients to your customers.

Overall, fragrance oils can be a safe and effective way to add scent to your handmade soaps, but it's important to do your research and take the necessary precautions.

What are the pros and cons of using fragrance oils in soap?

Fragrance oils are synthetically produced in a laboratory and can contain numerous different ingredients. They are safe to use and, in some ways, more sustainable than essential oils. However, they are not natural, which may limit their market appeal.

Pros of Using Fragrance Oils in Soap:

• Available in a wide range of pre-mixed fragrances, so there is no need to know note blending.
• Available in impossible scents if you go down the essential oil route. For example, if you want to make strawberry-scented soaps, you would need to use a fragrance oil.
• More sustainable and do not require vast quantities of plant materials to produce.
• Can be carefully formulated to smell as close to something already occurring in nature as possible, or to convey a more abstract concept or feeling.
• The variety of fragrance oils available is useful for soap makers who want to channel a very specific scent in their product.

Cons of Using Fragrance Oils in Soap:

• May cause discolouration of your soap. For example, vanilla will generally turn brown.
• Can change colour or morph between colours during saponification and curing.
• Some fragrance oils accelerate trace or cause your soap batter to seize.
• Not natural, which may limit market appeal.
• If you sell your products, you are tied to the one supplier that you buy your chosen fragrance from.

How do you choose the best fragrance oil for soap?

When it comes to choosing the best fragrance oil for soap, there are several factors to consider. Firstly, it is important to decide on the purpose and theme of your soap. For example, if you're crafting a floral soap, opt for a floral fragrance oil. Think about your target audience and any potential skin sensitivities they may have. It is also worthwhile to test different fragrances to find the one that suits your soap best.

To ensure the best quality, opt for fragrance oils that are IFRA certified, highly concentrated, and specifically labelled as "soap safe" or "for use in soaps and cosmetics". This guarantees that the oils are safe for use and that you are aware of the ingredients infused in the fragrance oil. Additionally, look for oils that are free of phthalates and parabens, and review the SDS document to identify any potential allergens.

The scent of the fragrance oil is, of course, a crucial factor. Choose a scent that makes you feel relaxed and good while you're bathing and throughout the day. Popular choices include floral scents like lavender and rose, citrus fragrances like orange, and woodsy aromas like cedarwood and sandalwood. You can even create custom blends by mixing different fragrance oils to create unique scents.

When using fragrance oils in soap-making, it is important to follow the recommended usage rate, which is typically between 1% to 5% of the total soap weight. For cold process soap, a recommended usage rate is 30g of fragrance oil per kilogram of fats/oils in your recipe. This ensures that the fragrance oil does not affect the performance of the soap.

Lastly, consider any potential issues that may arise during the soap-making process. Some fragrance oils can cause acceleration or discolouration in cold process soaps, so it is important to add the fragrance at the lightest trace and stir by hand.

What are the recommended usage rates for fragrance oils in soap?

When creating your own soap, the amount of fragrance oil you use is important. Too much can be overpowering, while too little may not be noticeable. The amount of fragrance oil you use depends on the type of soap you are making and the strength of your fragrance oil.

For cold process soap, the recommended amount is 30g of fragrance oil for every kilogram of fats/oils in your recipe. This can be calculated based on the base oil amount in your recipe and not the total amount of soap. This is because water amounts fluctuate in soap-making depending on the recipe.

For hot process soap, the recommended amount is 15-20g of fragrance oil for every kilogram of fats/oils in your recipe.

For melt-and-pour soaps, the recommendation is 10g of fragrance for every kilogram of melt-and-pour soap base.

For lotions, creams, balms, shampoos, bath gels, etc., the recommendation is between 1-3% by weight.

It is important to note that some fragrances, especially floral ones, can cause cold process soaps to accelerate or 'seize'. To avoid this, make sure you are using enough water (at least 330g of water for every kilogram of fats/oils) and keep your temperatures at or below 38°C (100°F) when mixing your caustic soda solution with the fats/oils. Additionally, add the fragrance at the lightest trace, and stir by hand.

When blending essential oils, it is important to consider the ratio of each oil as some oils can be overpowering. For example, you may want to use a 50/50 ratio of lavender and mint in your CP soap to ensure that the mint does not overpower the lavender.
