If you’re new to soap making, you may have come across various ingredients and additives that enhance the quality and benefits of handmade soap. One such popular ingredient is birch tar, which is known for its therapeutic properties and has been used for centuries in traditional medicine.
Birch tar, also known as Russian oil, is a potent ingredient obtained from the bark of birch trees. It has a strong, smoky aroma and is commonly used in skincare products such as soaps, shampoos, and ointments. However, when it comes to using birch tar in cold process soap, the question arises – how much birch tar should be used to get the desired results? Let’s find out.
Understanding the Cold Process Soap Making Method
Cold process soap making is the traditional method of producing soap using oils, lye, and water. In this process, the lye (a mixture of sodium hydroxide and water) reacts with the oils to form soap through a process known as saponification. This reaction can take up to 6 weeks, depending on the oils used and the desired hardness of the soap.
During this time, any fragrances, colorants, or additives can be added to the soap base. One such popular additive is birch tar, which not only adds a unique scent but also has numerous benefits for the skin.
The Ideal Percentage of Birch Tar in Cold Process Soap
Before adding birch tar to your soap recipe, it’s essential to understand the recommended percentage to achieve the desired results. The ideal percentage of birch tar in cold process soap is between 1-3% of the total oils used in the recipe. For example, if your recipe contains a total of 500g of oils, 5-15g of birch tar would be an appropriate amount to use.
Using more than 3% of birch tar can result in a very strong and overpowering scent, which may not be desirable for some users. Moreover, using less than 1% may not be enough to get the desired fragrance and benefits of birch tar.
Fragrance Considerations
While birch tar has a distinctive smoky aroma, it can also vary in its intensity, depending on the method of extraction and the quantity used. It’s essential to note that not all birch tar oils are created equal, and some may have a stronger scent than others.
Therefore, before adding birch tar to your soap recipe, make sure to do a small test batch to determine the ideal percentage for the brand of birch tar oil you’re using. This will help you achieve the desired fragrance and avoid using too much, resulting in an overpowering soap.
