How To Make Custom Soap With Our Soap Blends – Part One

 

At Botanie, we’ve crafted the perfect soap-making oil blends — unique combinations of organic sunflower, safflower, palm, coconut and castor oils sure to make high-quality bar soap. As a great place to start, pre-blended base oils make the soap-making process more convenient while still allowing you to create your custom soap. In addition to convenience, these blends are tried-and-true and have been proven to create wonderful cleansing bars that are hard and long-lasting, full of moisturizing properties, and produce a dense, creamy lather.

There are multiple ways to customize the oil blends, including adding additional oils or butters for superfatting, creating your custom essential oil scent blend, and adding specific herbs or botanical ingredients for different colors and exfoliating properties. In this post, I want to specifically address superfatting.

You can use the following table and methods to create custom soap with different superfat levels with our oil blends. The table provides the different levels of water and sodium hydroxide (lye) you should use with your base oils to achieve certain superfat levels. A custom soap containing a good ratio of oils and lye will have between 4%-10% extra oil. The process of superfatting soap ensures that all the lye is reacted out, allowing for a safe bar. This also adds extra oil to the soap, which provides additional moisturizing benefits.

There are two ways to go about the superfat process. One, you can simply use the numbers in the table to achieve a certain superfat level for a predetermined amount of oil. In the example below, the combination of water and lye used with 14 pounds of base oils results in a 5% superfat level batch of soap, meaning that 5% of the base oils do not get saponified (turned into soap), but instead remain unchanged and continue to keep their specific beneficial moisturizing properties. For quantities of oil above 5 pounds, such as a 35 pound oil blend, simply take the 5 pound oil row and multiply the lye and water ounces by 7 to get your needed lye and water ounce values.

The second superfat process involves adding extra oils or butters to the oil blend in order to create a really moisturizing batch of soap. This process adds additional superfat properties on top of the already calculated superfat levels in the table above. For our 14 pound oil blend, we recommend up to an additional 3 ounces of another oil (ex. Jojoba Oil, Olive Oil, Rosehip Seed Oil) or butter (ex. Shea Butter, Cocoa Butter, Mango Butter), which will produce very moisturizing bars. For those that may be working with higher quantities of oil, this works out to .2 ounces of superfat oils per 1 pound of base oils. If you want to make sure your final bars remain a firm but still have some extra moisturizing properties, 1 – 2 ounces of additional oils should do the trick.

Starting with a base oil blend can be very helpful and convenient and allow you to still create your custom soap. We hope that these superfatting examples and table are a useful soap-making resource and help everyone take their custom soap to another level through superfatting. Understanding the process is important — but for a quicker alternative to making superfat calculations, you can also use our sponsored recipe calculator on SoapCalc.net.
