Soap base is a pre-made, solid form of soap used as a starting point for creating custom soap products. It’s designed to be melted and then mixed with various additives like fragrances, colors, and textures to create unique soap bars. There are several types of soap bases, including:

1. Glycerin (Transparent) Base: This base produces clear or translucent soaps and is known for its moisturizing properties.
2. Shea Butter Base: Enriched with shea butter, this base is moisturizing and often used for a luxurious feel.
3. Goat Milk Base: Contains goat milk, which is gentle on the skin and adds moisturizing benefits.
4. Olive Oil Base: Rich in olive oil, this base is known for its nourishing and conditioning properties.
5. Coconut Oil Base: Adds lather and cleansing properties to the soap.

To use a soap base, you typically cut it into small pieces, melt it (usually in a microwave or double boiler), and then mix in your chosen additives before pouring it into molds to set. This method is popular because it’s relatively easy and allows for customization without needing to create soap from scratch.
