Cold Process Soap Making
Overview
Cold process soap making is a popular method amongst soap crafters. It involves mixing oils with sodium hydroxide (lye) to create a chemical reaction known as saponification. This reaction transforms the oils and lye into soap, resulting in a bar that is mild, gentle, and suitable for sensitive skin types.
Ingredients
To make cold process soap, you’ll need a combination of oils, lye, and water. The specific oils used will depend on your preferences and the properties you want your soap to have. Common oils used in cold process soap making include coconut oil, olive oil, and palm oil. It’s important to use lye and oils in the correct proportions to ensure a safe and effective soap.
Procedure
The cold process soap making procedure involves several steps. First, you’ll need to measure out and combine the oils and lye solution. This mixture should be stirred until it reaches a trace, which is when the soap batter thickens to a consistency resembling cake batter. Once the trace is achieved, any additional ingredients, such as fragrances or colorants, can be added. The soap batter is then poured into molds and left to cure for several weeks.
Curing Time
One disadvantage of cold process soap making is the longer curing time. Cold process soaps typically require at least four to six weeks of curing before they are ready to use. During this time, the soap hardens and the excess moisture evaporates, resulting in a longer-lasting and better-performing bar of soap. While the curing time may be a drawback for those eager to start using their handmade soaps, it is necessary to achieve the desired quality.
Hot Process Soap Making
Overview
Hot process soap making is another popular method used by soap crafters. This method involves heating the soap using an external heat source before pouring it into a mold.

Rebatch soap making doesn’t require curing time since the soap has already undergone saponification in its original form.
Hand-milled Soap Making
Overview
Hand-milled soap making, also known as rebatch soap making, is a method that involves melting and reforming pre-made soap. This method allows you to add your own personal touch and ingredients to create unique bars of soap.
Ingredients
The main ingredient for hand-milled soap making is pre-made soap. You can use unscented or lightly scented soaps to preserve the integrity of your added fragrances. Additionally, you can add fragrances, colorants, exfoliants, or other ingredients to customize your hand-milled soap.
Procedure
To make hand-milled soap, you’ll start by grating or chopping up your pre-made soap into small pieces. These soap pieces are then melted and blended together in a double boiler or slow cooker. Once fully melted, any additional ingredients can be added. The soap mixture is poured into molds and left to cool and harden. Hand-milled soap making doesn’t require curing time since the soap has already undergone saponification in its original form.
