Soapmaking Terms

When learning about soapmaking there are a few terms you will come across. This page will help you understand them.

M&P (Melt and Pour): This refers to the glycerin soap bases that you can puchase in craft stores and other places. Cut them up, heat them in the microwave or over a double boiler and pour them into molds (adding something fun along the way).

CP (Cold Process): When using this process, soap is made by combining fats with lye and water at high temperatures. This is a popular method among soapmaker because they have more control over the final product.

HP (Hot Process): A soapmaking process that is similar to cold process, but once the fats are mixed with the water and lye the mixture is cooked to have more control over the final product. A little more involved than cold process.

EO (Essential Oil): The fragrant oil that is extracted from a particular plant. Essential oils can be added to soap for a more natural fragrance. These oils have aromatherapy properties that are generally lost in the soapmaking process, but can be beneficial in lotions and other products that do not go through that chemical process.

FO (Fragrance Oil): A combination of synthetic and/or natural fragrances. You can purchase fragrance oils that have been tested for cold process soapmaking. Using a tested fragrance will help avoid unplanned chemical reactions.

Saponification: The chemical change that takes place when oils and sodium hydroxide (lye) are combined using the soapmaking process.

Superfatting: Adding a small percentage of fat to your soap that will not be used up in the saponification process. This leavea s small percentage of fat in your end prouduct that adds mildness to your soap. Superfatting at a ratio of between 5% and 8% will give your soap the desired mildness without making it too soft.

Free Fat: The extra fat that is left in your soap, and not saponified, when you use a recipe that is superfatted.
