The Basics: How to Make Solid Soap
Saponification Methods
To understand how to make solid soap, you must first grasp the chemical principles behind it. Saponification is the reaction between a fat and a strong base that creates soap. Here are the main methods:

The most popular technique for learning how to make solid soap is cold process saponification. It preserves the properties of the oils used.
Advantages:
- Preserves oil properties
- Gentle method that retains active ingredients
- Creamy texture of the final soap
Disadvantages:
- Long curing time (4 to 6 weeks)
- Important precautions required with lye
2. Hot Process
This variation speeds up the saponification process through heat.
Advantages:
- Soap is usable more quickly
- Ability to add delicate ingredients at the end of the process
Disadvantages:
- Additional equipment needed
- Sometimes less homogeneous texture
3. Melt and Pour
Ideal for beginners wanting to learn how to make solid soap without handling lye.
Advantages:
- Easy and safe
- No handling of lye
- Immediately usable
Disadvantages:
- Less natural
- Limited customization
